CNC Machine Buyer’s Guide: Types, Uses, Price, and Definitions

Today, CNC machining is utilized in every manufacturing segment, but it wasn’t always so. Once upon a time, manual machines ruled the manufacturing processes. These machines typically required one operator, often a skilled machinist, for each milling machine, lathe, grinder, etc., so the machining processes were usually labor intensive. Occasionally, a creative worker would devise a way to run multiple machines when long-running operations allowed, but those were the exceptions.

Eventually, the numerical control (NC) machining process emerged on the scene, and machine shops had their first taste of automation. The machining instructions were punched on paper tape and a tape reader system interpreted those instructions. NC programs were difficult to edit (you made a new tape each time), not always reliable, and you could not store the programs.

Computer numerical control (CNC) evolved from and improved the NC method by using computerized controls to manipulate cutting tools and machines, creating nearly any custom shape imaginable.

We will look at the various CNC types, how they work, how manufacturers use them, and what to look for as a buyer, including their cost. But first, a bit of background information might help you better understand these remarkable machine tools.

What Does CNC Mean?

CNC stands for computer numerical control, a computerized manufacturing process using software and code to control the movements of various types of CNC equipment. With the help of CNC technology, machinists and other skilled workers use mechanical design, drawings, mathematics, and computer programming skills to produce parts. For example, CNC programmers and operators can take a metal workpiece and create a critical aerospace or automotive component. Many modern machines combine multiple tools into one, streamlining the CNC machining process.

What is the Function of CNC?

The primary function of CNC is controlling the motions of a machine tool. Digitized data, a computer, and a computer-aided manufacturing (CAM) program work together to control, automate, and monitor the movements of the CNC tools. Large industrial machines typically have a computer integrated as a dedicated onboard controller, while smaller hobbyist models use an external computer.

The CNC controller works with several motors and drive components to execute and control the programmed motions. A feedback system continuously monitors and adjusts the cutter’s speed, feed rate, and position on more sophisticated machines.

What is an example of a CNC Machine Tool?

The milling machine is probably the most popular example of a CNC machine tool. Still, several others exist, including lathes, electric discharge machines (EDM), grinders, laser cutters, plasma cutters, waterjets, CNC routers, and 3D printers. And although the CNC machining process for each of these varies to some degree, the essential principles of the machining process stay the same among all of them.

Let’s examine these machines individually to determine what is unique about each one of them.

1. CNC Milling Machines

How Does a CNC Milling Machine Work?

The CNC milling process starts with a part designed on computer-aided design (CAD) software before being converted into a format the CNC mill can read. Computer-aided manufacturing (CAM) software exports this to a CNC machine program, typically in G-code format. The machine reads the coded instructions and puts them into operation, directing every move the machine makes. This process duplicates the CAD design in the appropriate material with precision, high-production output, less labor, and repeatability.

What are the Uses of a CNC Milling Machine?

One of the critical benefits of CNC milling is its versatility. CNC mills can cut materials—steel, iron, aluminum, alloys, etc.— and produce custom-designed parts more quickly than traditional machining methods. They can machine from a vertical or horizontal position, mill flat or on an angle, and create irregular surfaces or cavities.

CNC machines are ideal for mold work, where two or three axes of the milling table must be controlled simultaneously to produce cavities and surface contours. These machine tools are excellent for everything from cast iron foundry patterns and core boxes to the most complex stainless steel aerospace, military, and medical parts.

What Should You Consider When Purchasing a CNC Mill?

  • The machine’s specification: Matches the CNC mill’s size to the type of work you’ll be doing.
  • Manufacturer: Like other products, some top CNC milling machine brands have a reputation for excellence
  • Ease of programming: Each machine tool is different, so make sure you can create programs with this one
  • Space in your shop: Check the footprint of the machine to ensure it will fit in the available space
  • Service: The manufacturer must provide affordable support when you need it

What are the Prices of a CNC Milling Machine?

You can purchase a desktop CNC milling machine for as low as $3,500.00, a high-quality 9” x 49” Bridgeport-type CNC vertical mill for $12,500.00, an entry-level 3-axis vertical machining center for between $60,000 and $100,000, and a production 5-axis CNC mill for $500,000 and up.

2. CNC Lathe Machine

How Does a CNC Lathe Machine Work?

As with the CNC mill, the CNC lathe requires a computer-aided design (CAD drawing) before being converted into computer-aided manufacturing (CAM) format and exported to a CNC machine program with a tool path in G-code format.

With the CNC lathe, the workpiece is held between two centers, in a lathe chuck or a collet. The spindle turns, and the cutting tool moves into the material, creating round parts and drilled or bored holes. Unlike manual lathes, CNC lathes can handle complicated work of various sizes and usually require a skilled operator with thorough training.

What are Some Common Uses of a CNC Lathe Machine?

CNC lathes feature a spinning spindle and a fixed tool for making cylindrical parts for many industries in the metalworking and woodworking industries, making them almost as versatile as the CNC mill.

As a production machine tool, specific CNC lathe machines can produce thousands of machined parts in one shift. Other smaller machines are designated for machining smaller quantities and would be appropriate for maintenance and jobbing shops.

CNC lathe machines can remove material quickly for parts that don’t require a smooth finish or slowly when detailed features require a fine finish. CNC lathe machines are in almost every industry, including automotive, aerospace, firearms, and electronics.

Here are a few specific examples:

  • Camshafts
  • Screws
  • Crankshafts
  • Baseball bats
  • Table and chair legs
  • Gun Barrels
  • Musical instruments

What Should You Know Before Deciding on a CNC Lathe?

  • Consider the projects you will take on: What kinds of parts and materials will you be producing?
  • How many axes will you need for these parts?
  • Is the CNC lathe compatible with your existing CAM software?
  • Will the machine fit in your shop?
  • Will the parts fit on your CNC lathe (length and diameter)?
  • Will the manufacturer provide affordable service and support when you need it?

What are the Prices of CNC Lathe Machines?

You can pick up a small CNC lathe for around $5,000 or an entry-level two-axis CNC lathe for between $15,000 and $50,000. A large production lathe could set you back $300,000.

3. CNC Wire Electric Discharge Machine (EDM)

How Does a Wire EDM Work?

Wire EDM is a manufacturing process that uses a thin brass or copper wire to cut hardened workpieces. The wire acts as the electrode, and the material is removed from the workpiece by frequent current discharges between two electrodes (the wire and the workpiece). The electrodes are separated by a dielectric fluid (typically deionized water) and subject to an electric voltage. The wire continuously unwinds from a spool.

What are Some Common Uses of Wire EDM?

Wire EDM is frequently used in the mold and die manufacturing processes, primarily for extrusion dies and blanking punches. EDM works well for prototypes or total production runs and is most effective in manufacturing metal components and tools. The automotive, aerospace, and electronics industries often use EDM for their parts.

What Should You Consider When Purchasing a Wire EDM?

The two most critical factors (after the initial price) are the ongoing expenses of consumables and maintenance. In other words, how quickly will this EDM get your parts off the machine using the least amount of wire, and how much downtime will you sustain from maintenance and repair? These factors are hard to quantify unless you have EDM experience, so your best bet is thorough research and talking to a few manufacturers with wire EDM knowledge.

How Much Do EDMs Cost?

Entry-level wire EDMs can begin below $7,000, while top-of-the-line models loaded with features may start at $100,000.

4. CNC Grinders

How Does a CNC Grinder Work?

CNC grinding machines are machine tools that use a high-speed rotating grinding wheel to remove metal from a workpiece. A CNC grinder is programmed to improve surface finishes and remove material while holding the proper tolerances on a workpiece.

Although there are several types of CNC grinders, the two most frequently used are the surface grinder and the cylindrical grinder. CNC surface grinders operate automatically from a program creating the finest finish on a flat surface. In contrast, cylindrical grinders work on round-shaped workpieces to grind the outside diameter (OD) or inside diameter (ID) to precise specifications.

What are Some Common Uses of Grinders?

Grinding is prevalent in many industries and for various applications, including:

  • Anytime a surface finish is critical
  • Grinding various tools and cutters
  • Precise internal grinding on tapered, straight, and formed diameters
  • Cylindrical grinding on outside diameters such as shafts, pistons, camshafts, etc.
  • Slitting and parting operations

What Should You Consider When Purchasing a Grinder?

After you have determined the type of grinder you need, based on the kind of work you’ll be doing (flat or cylindrical), look at the grinder’s specifications:

  • Grinding wheel diameter and speed
  • Machine horsepower
  • Frequency and volt rating
  • Input power required to operate the machine for various operations
  • Material to be ground
  • Coolant system

How Much Do Grinders Cost?

CNC cylindrical grinders start below $20,000, while a sizeable heavy-duty brand could cost $180,000. Most CNC surface grinders are in the $25,000 to $60,000 price range.

5. CNC Laser Cutters

How Does a CNC Laser Cutter Work?

CNC laser cutting is a non-contact, thermal-based machining operation focusing a high-intensity laser beam on a metal workpiece, melting and cutting it to create the desired shape. The process involves a CNC laser cutter featuring a laser head containing a focusing lens and a nozzle. CNC lasers use compressed gas to cool the focusing lens and remove the vaporized metal from the workpiece, and it also flows through the nozzle that ejects the laser beam.

The heat density where the beam meets the workpiece is exceptionally high and results in the vaporization of the metal. CNC programming and technology control the movements of the laser head and beam on the work surface, forming custom shapes and designs.

What are Some Common Uses of Laser Cutters?

Laser cutting machines are often valuable for engineering, where the precision cutting of components for machines is critical. Laser cutters also cut structural and piping materials and flat sheet metal. CNC technology allows it to change settings and etch or engrave various designs on metal, wood, and plastic. The size and capacity of the laser cutter determine the type of work it can handle.

What Should You Consider When Purchasing a Laser Cutter?

There are three main types of laser cutters from which to choose:

  • CO2 Laser Cutters: These are the most popular and well-regarded type because they are efficient and less expensive. They work best for cutting glass, plastics, leather, wood, and acrylic.
  • Crystal Laser Cutters: With smaller wavelengths and higher intensity than CO2 lasers, crystal laser cutters can cut through thicker materials, such as metals, plastics, and ceramics.
  • Fiber Laser Cutters: Also known as solid-state lasers, fiber laser cutters offer the advantage of cutting reflective and conductive metals, three times the efficiency of CO2 cutters, and no moving parts, meaning lower maintenance. They are suitable for metals and organic materials.

How Much Do CNC Laser Cutters Cost?

Laser cutters range from $8,000 to over $250,000, with the lower-priced model handling small, low-volume projects. For many commercial applications, a metal laser cutter will probably exceed $20,000.

6. CNC Plasma Cutters

How Does a Plasma Cutter Work?

CNC plasma cutters are computer-run machines that move a high-definition plasma torch using the numerical coding (G-code) programmed into the computer. The plasma cutter operates by forcing a gas or compressed air through a nozzle at high speeds and then introducing an electric arc to the gas, creating a plasma that can cut through metal.

Some of the gases used in plasma cutting include:

  • Oxygen: Good for cutting mild steel up to 1-1/4 inches thick
  • Argon and hydrogen mix: Provides high-quality, smooth cuts in stainless steel and aluminum
  • Compressed air: Best for low-current cutting applications in metals up to 1-inch thick
  • Nitrogen and methane: Work for thin stainless steel

What are Some Common Uses of Plasma Cutters?

You will find plasma cutters in fabrication shops, automotive repair and restoration, construction, and salvage operations. Artists and designers use it to create signage, sculptures, and decorative panels for various interior projects.

Ideally, plasma can be used for cutting steel, brass, copper, and other conductive metals, although it’s less effective on stainless steel and aluminum. Plasma cutters work best when cutting more significant parts with loose tolerances and are perfect for general plate cutting since it cuts quickly and is cheaper than other cutting methods.

What Should You Consider When Purchasing a Plasma Cutter?

Plasma cutters work on practically any type of metal, so the primary consideration in choosing one is metal thickness and how much you plan to cut. Answer the following questions as you match a plasma cutter to your type of work:

  • Are you cutting thick metal?
  • How often will you use the plasma cutter?
  • Will you adapt your power outlets for your new cutter?
  • Do you now have a generator you plan to use with your plasma cutter?
  • Will your electrical current fluctuate?
  • Do you need a portable unit?

How Much Do CNC Plasma Cutters Cost?

Depending on size and features, a CNC plasma cutter can run between $12,000 and $300,000. Because plasma technology has become cheaper to produce, the price has dropped significantly over the last five years.

7. CNC Waterjets

How Does a Waterjet Work?

Waterjet cutters are machine tools that use a high-pressure stream of water to erode a narrow line on a workpiece. Occasionally, a granular abrasive is added to the waterjet to enhance its cutting power. The abrasive is added at the nozzle, making it easy to switch between water-only and abrasive cutting.

Cutting happens when pressurized water is forced through a ruby or diamond nozzle into a mixing chamber, creating a vacuum and drawing garnet sand into the stream where it is fired at the material. Since the jet stream moves at up to 2.5 times the speed of sound, the cutting can be done at high feed rates, making it an efficient and powerful precision cutting tool.

What are Some Common Uses of Waterjets?

Waterjets are used in numerous glass projects, including kitchen splashbacks, stained glass, shower screens, and floor inlays. Other applications include:

  • Metals such as steel, aluminum, titanium, brass, and nickel
  • Stones, including floors, stepping stones, border tiles, and bench tops for kitchens and vanities
  • Soft materials like foams, interior automotive components, rubber, plastics, and cork
  • Metal parts for the automotive industry, including bumpers, truck bed liners, fiberglass body parts, and trim
  • Aerospace industry components like engine parts, cabin panels, and aluminum body parts
  • The electronics industry uses waterjets for circuit boards and many other parts

What Should You Consider When Purchasing a Waterjet?

  • Make sure you buy a waterjet that can handle your parts, the supplied sheets, and future growth. A 5’ X 10’ or a 6’ X 12’ machine usually works best.
  • The initial price and operating and maintenance costs of abrasive recycling systems almost always outweigh the cost of fresh abrasive.
  • Choosing an Ultra High-Pressure Pump is not always necessary. A higher HP option with an excellent track record should work just as well and save you money.
  • If you want an abrasive removal system, check the aftermarket before deciding on an expensive in-tank dedicated system.

How Much Do CNC Waterjets Cost?

A small waterjet cutting system starts at around $60,000, while complete custom systems can run into the hundreds of thousands.

8. CNC Routers

How Does a CNC Router Work?

Like the other CNC machine tools on the list, CNC routers operate with CAM software programs and G-code to control the machine’s movements, time, and direction. They have spindles that hold cutting tools to create shapes in various materials on a work table. The cutting tool can drill holes, mill cavities, engrave, and more.

Much like a milling machine, the CNC router’s drive system sends the spindle in three directions along the X, Y, and Z axes, allowing it to machine complex patterns and contours. Although there are similarities between the two machines, CNC routers are less robust than mills and are better suited to cutting softer materials like wood.

What are Some Common Uses of Routers?

Some of the most frequent applications for a CNC router include:

  • Furniture making: CNC routers can produce various furniture items in large quantities
  • Sign making: A CNC router is an excellent choice for creating signs because of its versatility
  • Cabinet making: CNC routers lend themselves to the making of shelves, drawer fronts, side panels, and custom doors
  • Arts and crafts: Picture frames, Christmas decorations, and plaques are a few examples of creations that are possible on the CNC router
  • Molds and prototyping: CNC routers are ideal for machining epoxy, foam, and clay 3D design models, as well as cutting molds from EPS foam, polyurethane foam, EVA foam, and plastic.

What Should You Consider When Purchasing a CNC Router?

  • What type of drive system? You must choose from rack and pinion, lead screw, and ball screw. Ball screw is the most expensive but allows for cutting larger workpieces with greater accuracy and efficiency.
  • Servo or stepper motors? Steppers have more magnetic poles than servo motors for enhanced accuracy. Servo motors supply twice their rated torque for periods and typically have greater efficiency.
  • Machine’s weight: As a rule, heavier machines are more robust, meaning less vibration and more accurate cutting.
  • Software: Don’t skimp on software. Your CNC router does what the software tells it.

How Much Do CNC Routers Cost?

The basic three-axis models range from $5,000 to $10,000, while mid-range machines for large panels and signage will cost anywhere from $25,000 to $50,000. High-end machines typically run from $50,000 to $150,000.

9. 3D Printers: In a Class by Themselves

The previous eight machines are part of the subtractive manufacturing process. In other words, these machine tools remove material by various methods. On the other hand, 3D printers represent an additive manufacturing process where three-dimensional solid objects are created from a digital file.

In this additive process, the part is created by laying down successive layers of material, with each layer seen as a thinly sliced cross-section of the object. 3D printing is the opposite of subtractive manufacturing and is a unique and relatively new process that continues to evolve. As such, it deserves an in-depth and detailed examination.

For now, we will merely mention this exciting technology in passing.

Two Examples of Top-Shelf CNC Machines

Although modern computers are at the heart of every CNC machine, old-fashioned quality engineering separates the great ones from the also-rans. The CNC Masters Supra Vertical Knee Mill and their 1440 CNC Lathe Machine are two prime examples of excellence. Both CNC machines are built in the USA (Irwindale, California) and backed by an expert support team.

CNC Supra Vertical Knee Mills

Slide 1

4. Navigate and Edit Your Program through the MX interface with Ease
With a few clicks of the mouse or using touch screen technology, you can easily navigate through the MX interface importing saved programs into the Editor from the File drop down menu. Using standard windows features to edit your program you can then lock the Editor Screen to avoid accidental editing, and if you need to insert a line in the middle of a program, just click on [ReNum] to re-number your tool path list.
You can create a program or import CAM generated G-code tool paths into the Editor
The X Y and Z W arrow jog buttons are displayed from the point of view of the cutter to avoid confusion when the table and saddle are moving. You can also adjust your spindle speed and coolant control while jogging each axis.

Slide 1

5. Feed Hold – Pause in the Middle of your Program
Feed Hold lets you pause in the middle of a program. From there you can step through your program one line at time while opting to shut the spindle off and then resume your program.
You can also write PAUSE in the middle of your program and jog each axis independently while your program is in pause mode.

Slide 1

6. Hot Keys
Hot Keys is an alternative method to easily control your machine using your hard or touch screen keyboard. One can press P to pause a program, press S to turn Spindle On, G to run a program, Space Bar to Stop, J to record your individual movements one line at a time to create a program in teach mode.

Slide 1

7. Pick Menu – for conversational mode programming
Write FANUC style G-codes directly into the Editor or select commands off the [Pick] menu and write your tool path program in conversational mode such as what is written in the Editor box. You can even mix between conversation commands and G-codes in the same program.

Slide 1

8. Pick Menu List of Options
Use commands such as MOVE, SPINDLE ON/OFF, COOLANT ON/OFF, PAUSE, DELAY, GO HOME…. to write your tool path programs in conversational mode.

Slide 1

9. Draw the Tool Path to verify it before pressing Go
Hit Draw to view your tool path program drawing, check out its run time, or even simulate the tool path in 3D mode. This can be helpful to quickly verify your program before running it. You can also slow down or speed up the drawing or simulation process.
You can also hit Go within the Draw Window itself to verify the cutter’s position on the machine. The current tool path will be highlighted and simultaneously draw out the next path so you can verify what the cutter will be doing next on the program.

Slide 1

10. Run each tool path independently to study its movement
1. Run the machine on Trace mode. You can run each tool path independently, one line at a time to study the tool path movement on the machine to verify the position of the application and if any fixture/vise is in the way of the cutter’s path.

2. You can also verify your program by clicking on the Trace and Draw buttons together. This will allow you to view each tool path independently one line at a time in the Draw Window.

Slide 1

11. Counters display in Inches or Millimeters – Continuous Feed
1. When running a program, the counters will display a “real-time” readout while the machine is in CNC operation without counting ahead of the movement.
2. The current tool path is highlighted while the machine is in operation without causing slight interruptions/pauses as the software feeds the tool path to the machine. The MX internally interprets a program ten lines ahead to allow for “continuous machining” avoiding slight interruptions as the machine waits for its next tool path command.
3. “Run Time” tells you how long it takes to run your tool path program.

Slide 1

12. Use the “Go From Line” command to start in the middle of your program
If you ever need to begin your program from somewhere in the middle of it, use [Go From Line] which you can find under Tools. The Help guide will walk you through how to position the cutter without losing its position on the machine.

Slide 1

13. Exact Motion Distance without over-stepping on an axis while jogging
Use “Relative ON” to enter a specific coordinate to jog any of your axes to an exact location without having to write a program. It’s like using “power feed” but easier. You can jog an exact distance on any of the axes without needing to keep the key pressed down and mistakenly over-step the movement releasing your finger too slowly off the jog button.
Let’s say you need to drill a hole exactly 0.525” using the Z. So you enter 0.525 in the Z box. Next, adjust the JOG FEED RATE slider for the desired feed rate. Then “click once” on the +Z or -Z button to activate the travel. In this case you click once the -Z button first to drill the hole exactly 0.525”. Then click once on the +Z button to drive the axis back up 0.525”.

Slide 1

14. Teach Mode – Jog Input
You can create a tool path program by storing each point-to-point movement by simply jogging an axis one at a time. Click on either of the Jog Input buttons to store each movement on the Editor Screen. You can then add Spindle ON, feed commands, and press GO to run the new program as needed. This is a great feature to help you learn to create a program by the movements you make on the machine without necessarily writing out an entire program first.

Slide 1

15. Override on the fly to adjust the Jog Feed to Rapid or the Spindle Speed during the middle of a program
1. Jog Feed and Rapid with Override: You can adjust feeds using the slider from slow minimum 0.1″ per minute to a rapid of 100″ per minute of travel. You can even micro-step your jog as low as 0.01”/min. The [-][+] buttons allow you to fine tune feeds in 5% increments while the program is in motion.
2. Spindle Speed with Override: You can adjust speeds using the slider from a slow minimum RPM to the max RPM according to the machine setup. The [-][+] buttons allow you to fine tune feeds in 5% increments while the program is in motion.

Slide 1

16. Adjust Counters using Pre-Set if you cannot begin the program from 0.00
In a situation where you cannot begin your cutter at it’s 0.00 location, you can “Pre-Set” directly into the counters by typing in your beginning coordinate. You can press Go from here to run your program. You can also “zero all” or “zero” your counters independently. With one click of the [Return to 0.0] button, all axes will travel back to its respective 0.0 on the machine.

Slide 1

17. Set and Save your 0.00 position for future runs
Set and save your 0.00 position on the machine. These coordinates will be recorded as the first line of the program in the Editor Screen. Should you desire to return to this program at a later date, you only have to click on the Set Zero Return button. This will command the machine to automatically jog each axis to its saved “set” 0.00 position according to the recorded coordinates at the first line of the program.

Slide 1

18. Create a “Home” position to clear your application and run multiple times
Let’s say you need to machine one application times 100 pieces. This usually requires a jig to retain that physical 0.00 position. But in this case, you want the program to end with a clearance of the axes to easily switch out the next piece of stock and start again. With Save Home, you have the ability to save this offset (home) position while still retaining your Set Zero position where the machine will mill your part out. Pressing [Save Home] will record this new position under the Set Zero line in your program.
Pressing [Go Home] will jog your axes back to your “saved home” position where you originally pressed the Save Home command. You can also input GO_HOME from the Pick Menu as its own tool path in your program. At the completion of your program the axes will end at your Home position. Replace your part, then press [Return to 0.0] button to allow the axes to return to its zero position, and press Go to start your next run.

Slide 1

19. Disable the axis motors to manually hand crank each axis into place
Easily de-energize the axis motors by clicking [Disable Motors] to crank each axis by hand, and then press [Reset Control] to re-energize the axis motors.

Slide 1

20. Change up to 30 tools with compensation, and store your tool offsets for other programs
The MX supports…

21. Use the optional ATC rack up to 8 tools for milling, drilling, and rigid tapping applications
The CNC Masters Automatic Tool Changer Rack and Tools (US Patent 9,827,640B2) can be added to any CNC Masters Milling Machine built with the rigid tapping encoder option. The tutorial will guide you through the set-up procedure using the ATC tools.

Slide 1

22. Use the optional Rigid Tapping Wizard without the need for tapping head attachments
When you order your CNC Masters machine, have it built with the optional rigid tapping encoder. You can take any drill cycle program and replace the top line with a tapping code created by the wizard to tap your series of holes up to 1/2” in diameter.

Slide 1

23. Use the optional Digital Probe to scan the profile and/or pockets of your fun/hobby type designs to write your tool path program and machine out a duplicate of your original design To “surface” scan an object, you can program the probe along the X or Y plane. The stylus will travel over the part starting on the left side front corner of the object and work its way to the end of the part on the right side. Depending on how the stylus moves, it will record linear and interpolated movements along the X, Y, and Z planes directly on the MX Editor.
To “pocket” scan an object containing a closed pocket such as circles or squares, the scan will start from the top front, work its way inside of the pocket, and scan the entire perimeter of the pocket.
Under the Setup of the MX software you will find the Probe Tab which will allow you to calibrate and program your probe. Your “Probe Step”, “Feed”, and “Data Filter” can also be changed on the fly while the probe is in the middle of scanning your object.

Slide 1

24. Use work offsets G54-G59 for nesting applications
The work offsets offer you a way to program up to six different machining locations. It’s like having multiple 0.0 locations for different parts. This is very useful especially when using sub-routines/nesting applications.

Slide 1

25. Create a Rectangular Pocket / Slot with our selection of Wizards to help you build a tool path program
The Cycle Wizards for the mill or lathe makes it easy to create a simple tool path without needing to use a CAD and CAM software.
On this Wizard, the Rectangular Pocket / Slots, can be used to form a deep rectangular pocket into your material or machine a slot duplicating as many passes needed to its total depth.

Slide 1

26. Create a Circular Pocket Wizard
Input the total diameter, the step down, and total depth and the code will be generated.

Slide 1

29. Create a Peck Drilling Program in Circular or Rectangular Patterns
Using the Circular or Rectangular Drilling Wizards, you can program the machine to drill an un-limited series of holes along the X and Y planes. Program it to drill straight through to your total depth, use a high-speed pecking cycle, or deep hole pecking cycle. You can program the cut-in depth and return point for a controlled peck drill application to maximize chip clearance.

31. Use Tool Change Compensation or the optional Auto Tool Changer Turret if your application requires more than one tool in a single program
You can offset the length and angle of each tool and record it under Tools in your Setup. The program will automatically pause the lathe’s movement and spindle allowing you to change out your tool, or allowing the optional ATC Turret to quickly turn to its next tool and continue machining.
On the MX interface, you also have four Tool Position buttons. Select your desired T position, and the auto tool post will quickly turn and lock itself to that position.

35. Facing / Grooving / Part Off Cycle Wizards – with Constant Surface Speed
These cycles can be used with Constant Surface Speed allowing the spindle speed to increase automatically as the diameter of the part decreases giving your application a consistent workpiece finish. With CSS built into the wizard, there is no need to break down the cycle into multiple paths and multiple spindle speed changes.

36. This is our list of supported G and M codes which can be found under Tools > G Code/ M Code List in the MX
If you plan to use a third-party CAM software to generate your tool path program, use a generic FANUC post processor and edit it to match our list of codes. As an option, we also sell Visual mill/turn CAM software which comes with a guaranteed post processor for our machines to easily generate your tool path programs based on your CAD drawings.
