CNC Jr.

It’s the first true milling machine on the list. The CNC Jr from CNC Masters is a fully capable 3-axis CNC vertical milling machine. Heavy-duty cast iron construction and high-end X and Y ball screws mean the CNC Jr is ready to tackle virtually any project.

The CNC Jr is a benchtop milling machine offering the same power as many larger models. The CNC Jr is fully equipped and compatible with any CAD or CAM program that produces standard G-codes. It can also be operated manually when you don’t want the hassle of writing a new program for a simple operation.

The CNC Jr is equally at home in a small home workshop or a busy machine shop. It can handle production runs or intricate prototyping. The Jr is heavy enough to provide the necessary rigidity to ensure precision but light enough to qualify as a true tabletop milling machine. It’s a durable machine that will long outlast many of the other entries on this list.

Best of all, the CNC Jr is easy to learn and comes with all the tech support you need. Prices start at $5893 and can be customized with a 4th axis, coolant systems, upgraded collets, and other features as needed.

Baron Milling Machine

One of the most versatile machines on the list, the Baron is a larger CNC machine that still fits into the tabletop category. It’s perfectly capable of handling small to medium production runs. There’s no need to go easy on it; heavy-duty cast iron construction means that you can run the Baron every day without fear that it will break down.

The Baron features full 3-axis movement, with micro-stepper motors on the X, Y, and Z-axes. CNC Master’s custom software runs on Microsoft Windows and allows you to easily design any custom operation.

While a true vertical milling machine, the CNC Baron features a moveable spindle head that can be tilted and angled to achieve more of the effect of a horizontal milling machine. While capable of fully automated operation thanks to the advanced CNC controls, the Baron can also be operated manually with the flywheels. This allows skilled operators to perform smaller operations by hand, often faster than it would take to write a new program.

The Baron is turnkey and designed for simplicity and ease of use. There’s one port for oil and lube, manuals for both the machine and the CNC programming software, and the Baron is ready to go from the moment you turn it on.

If desired, the Baron can be customized with a fourth axis of movement. Please contact our sales team to learn more. Prices start at $6350, and like the CNC Jr are fully customizable as needed.

CNC Supra Knee Mill

The Supra is one of the best cheap CNC machines you’ll find today, a workhorse CNC milling machine. Cast-iron construction on a traditional knee mill, CNC Master’s Supra Knee Mill comes in two sizes. The 9 x 49 Supra has a max travel of 34” x 11.5” on the X and Y axes. The Z-axis is quill-driven for an extra degree of precision and accuracy. The result is an affordable CNC machine that’s fully capable of high-end work.

There’s also a larger Supra available in a 10 X 54 table, capable of max travel of 35.5” x 15.5” on the X and Y axes. The Z axis is quill driven. This larger Supra is fully capable of industrial work in virtually any setting, making it a great machine for small machine shops as well as high-end production facilities.

The full set of CNC controls also provides for operation recall; rather than reprogram the Supra every time you switch parts, you can build up a library of existing tool paths on the machine. That simplicity, combined with the Supra cnc milling machine power, sets it apart from other cheap CNC machines.

The Supra relies on CNC Master’s MX control software, included with each CNC Master’s CNC machine. The Supra CNC mill controls are compatible with most CAD software.

The 9 x 49 Supra starts at over $12,483; the larger 10 x 54 begins at just under $15,000.

CNC Max Milling Machine

The CNC Max milling machine is CNC Master’s top-of-the-line benchtop CNC machine. An upgraded version of the CNC Baron, the CNC Max features longer travel on the Y-axis and a high spindle speed. The result is a larger machine than the Baron, but one with a similar range of capabilities.

The CNC Max is constructed along the same lines as a classic Bridgeport knee mill, but with a slightly reduced profile to reduce floorspace.

Cast iron construction, true ball screw accuracy, and dovetail ways all make this a mid-size CNC machine capable of full-size work. The CNC Max could confidently be run 40+ hours each week, powering large production runs for a full-scale machine shop or manufacturing facility. A 2 HP main motor and micro-stepper motors ensure plenty of power and precision, with no unevenness or rough cutting.

The MX Software included with every CNC Masters machine is fully Windows 10 or 11 compatible. You’ll also be able to use it with third-party CAM software, so there’s no need to fret over operating systems. The Max is the best CNC machine CNC Masters offers for the discerning machinist.

Other CNC machines come without the necessary software or with a distinct lack of customer service. But the CNC kits from CNC Masters come fully supported by our knowledgeable, in-house support team.

The CNC Max is far more affordable for a desktop machine than most CNC machines. Prices start over $7,475.

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.

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.

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.
