Upon request for international orders, we can re-wire the Control Unit to meet 220-240vac standards at no extra charge.


The CNC MASTERS Master Operating Software for the CNC Jr, CNC Baron, CNC MAX, and CNC SUPRA Milling Machines




The CNC MASTERS Control Unit is designed to work hand in hand with our custom proprietary user friendly MASTER software program. This custom software has been optimized to work with 32 or 64 bit operating systems: Windows 7, or XP Pro with SP2 or better through your standard USB port. The MASTER software features a main windows panel interface that will allow the novice user of a CNC Mill to easily control the program and the machining of parts. The Master Software is used to operate the CNC Baron Mill.

The Master software runs standard FANUC G-code files from other CAD-CAM software such as MasterCAM, SmartCam, SurfCam, etc. The Master software also features its own programming language. It uses plain conversational language like "Move, Absolute, Incremental, Repeat, Rapid, Feed, Spindle on, etc.," which are all self explanatory. These commands are conveniently picked from the pull-down menus and placed on the main screen editor ready for the user to complete. You can easily build a file of commands to machine simple parts without the need to learn or use a CAD-CAM program! For example, you need a number of steel pieces drilled with 100 holes, each of 1/2" dia. by 1" deep at 0.600 centers. With a simple program, the CNC Jr. or the CNC Supra can do this operation with minimal supervision. The program will look like this:
	PROGRAM SAMPLE:
001 ABSOLUTE
002 MOVE X0 Y0 Z0
003 SPINDLE ON FORWARD SPEED 400 RPM
004 COOLANT ON
005 INCREMENTAL
006 CALL ROW 10 TIMES
007 SPINDLE OFF
008 COOLANT OFF
009 MOVE X0 Y0 Z0
010 END /MAIN PROGRAM
011 ROW /BEGIN SUBPROGRAM
011 MOVE Y-0.6
012 CALL DRILL_COLUMN 10 TIMES
013 END /ROW SUBPROGRAM
014 DRILL_COLUMN /BEGIN SUBPROGRAM
015 MOVE X.6
016 FEED 1.0 /INCHES PER MINUTE
017 MOVE Z-1.1
018 RAPID
019 MOVE Z1.1
020 END /DRILL CALL

The ability of the MASTER software to run and repeat "subprograms" with a single command line is a very powerful feature that will save the user considerable manual input and easily program custom "canned cycles" such as large DRILLING REPEATIBLE FILES that can be written with just a few lines. Verifying a new program can be easily done with the "trace" facility. In this mode you can step a program one line at a time and check the XYZ position counters, which serves as your DRO, against the blueprint of the part, or you can activate the "Draw file" command to see a graphic display of your file before you machine the part.

This is another program sample of a simple square with rounded corners:


	N00 ABSOLUTE
N01 MOVE X1.0 F5
N02 CCWCIRCLE X1.5 Y0.5 I0 J0.5
N03 MOVE X1.5 Y1.5

N06 CCWCIRCLE X-0.5 Y1.5 I0 J-0.5
N07 MOVE Y0.5
N08 CCWCIRCLE X0 Y0 I0.5 J0
N09 END

USE the CNC MAX with POPULAR CAD-CAM SOFTWARES


With the included G-CODES FILE INTERPRETER, the MASTER software can run files generated by many advanced CAM software packages, like VisualMill CAM software which uses solids and surface machining technology. Or, use others like MASTERCAM, SURFCAM, RHINO, ARTCAM etc. All you need to do is setup your post-processor to match the CNC Masters Milling Machine, and you will be able to machine the most complex surface program that your machining requires. The maximum file size will be controlled by the storage space available on the hard drive of the host computer. With the MASTER editor you can create, edit, load, or mix G-codes with the MASTER command language.

See how the Master Software interprets G-codes using Rhino CAD and VisualMill CAM optional software.

A testimonial from our customers, Holgate Enterprises in Florida using a CAD-CAM software on his CNC Supra Mill:

Hi CNC MASTERS,

I wrote the program on BOBCAD. It was a little tricky but basically I used it for a training exercise kinda like mountain climbing! Bobcad uses what they call "Solids". Under this category are "Primitives". There are five choices of these primitives: Sphere, Cube, Cone, Cylinder and Torus.

When using these, you must (always) instruct the program the size of these"parts". A chain is made up basically of Torus's and Cylinders. The torus being the ends (left and right) and the center portion is the cylinders. Unfortunately, the program will not write a half a torus. However, one can draw the whole torus and then"erase" half of it. After the first "Link" is successfully drawn and verified using the "render" command, then its just a matter of copying the link, pasting it (in the correct numerical distance to the right), rotating it 90 degrees (every other link is either vertical or horozontal.) and so on.

Upon completion, it has to be rotated every 90 degrees and ran again until the four quadrants are completed. Also, if you examine the picture, at the corners the two vertical sides finish with a half link turned 90 degrees and the top and bottom ones (shorter) must "meet" these corners too. So, as you can imagine, it was a real task and involved large degrees of visualization and so forth.

How accurate is Rhino?

Since many free-form modelers are not accurate enough for manufacturing or engineering analysis, and since Rhino is a free-form modeler, many people assume Rhino is not accurate enough for their application.

In fact, Rhino is just as or even more precise than most CAD software. Here are the details:

There are two common methods 3-D models are stored in computers.

    The first method is using meshes (sometimes called facets), which are usually used for rendering, animation, or conceptual design. While mesh modelers often have what appear to be precise techniques for creating models like spheres, boxes, splines, or even NURBS, behind the scenes they eventually turn everything into a mesh. Meshes are inherently inaccurate because a mesh is simply a collection flat triangles. Even if the surface is curved, a mesh modeler still represents it with flat triangles. This is fine for most renderings, animations, and games, but not when designing for manufacturing. It should be noted that many manufacturing processes use meshes but the mesh density must be under the control of the manufacturing application to achieve the desired accuracy. Rhino does not use meshes for modeling, but it can convert NURBS to meshes at any density as needed for file exports and rendering.

    The second method is NURBS. Most CAD, CAM, CAE, and CAID modelers, including Rhino, represent free-form shapes as NURBS. Products that use NURBS can potentially represent free-form shapes accurately enough for the most demanding application if they are diligent in their NURBS implementation. If an application’s primary focus is machinery design and not free-form shapes, it is likely that its NURBS implementation can be less than robust for demanding free-form modeling. This is typical of the mid-range feature-based parametric solid modelers that are so popular today.

Since Rhino’s focus is free-form NURBS modeling, its NURBS implementation is one of the most robust available today. Here are the primary considerations when evaluating whether a modeler is accurate enough for your application:

    • Position. Rhino, like most CAD products, represents position in double-precision floating-point numbers. That means the x, y, or z coordinate of any point can have a value ranging from as large as ±10308 to as small as ±10-308. Most CAD software, including Rhino, uses double-precision floating-point arithmetic.

      Because of the limitation of current computer technology, we expect calculations to be accurate to 15 digits of precision in a range from ±1020 to ±10-20. This limitation is found in all modern CAD products.

      Older CAD products often have additional limitations because they were developed originally to run on computers with less precision. For example, many CAD modelers are designed for performing calculations on geometry that is restricted to be in a box of size 1000x1000x1000 meters centered at the origin. (Geek alert: Another of the popular off-the-shelf modeling kernels requires parameterizations that are within a factor of 10 of being arc-length parameterizations.) Rhino has none of the limitations found in these older products.

    • Intersections. In Rhino, when two free-form surfaces are intersected, the resulting intersection curve is calculated to the accuracy specified by the user. The Rhino default accuracy (tolerance) is 1/100 millimeter. Many CAD systems have built in tolerances that the user cannot override.

      If you carefully examine the geometry other modelers produce from free-form surface intersections, free-form fillet creation, and free-form surface offsets, you will discover that this free-form geometry is actually calculated with accuracy between 10-2 and 10-4 meters even though they advertise precision of 10-8 (without mentioning that the units are meters).

    • Continuity (curvature change matched across a seam.) Most CAD products don’t even have tools to match curvature, let alone do it accurately enough for a discriminating designer. If your application requires smooth free-form surfaces such as airfoils, hydrofoils, lenses, or reflective surfaces, you need these tools found only in Rhino or high-end surface modeling products like CATIA and Alias.

    • Units. In Rhino the user can specify the units. The units are actually changed and then all calculations are done in those units. In many CAD products, units are only a display attribute. Even though you may have specified millimeters, all of the calculations are actually being done in meters. No big deal. You just move the decimal place over. Wrong! Read on.
    • Changing units. Changing units or unit conversions can be one of most commonly overlooked accuracy hazard in CAD/CAM. Most of us might think that converting from imperial units to metric units would introduce some inaccuracy while never giving millimeter to centimeter conversions a thought. Why? Because we think in decimal. But guess what! The computer doesn’t. It is binary (that is base 2, not base 10). That means one or more floating-point multiplies or divides are needed to convert from millimeters to centimeters. The inaccuracies introduced by converting from millimeters to centimeters are the same as those introduced by converting from millimeters to inches.

In summary, Rhino is as accurate or more accurate than any other CAD product on the market today. In addition, Rhino provides tools for setting accuracy and units as well as tools for controlling and evaluating continuity not found in most CAD products. Rhino does not have the limitations found any of the older CAD products.


CNC Masters MAX Milling Machine Accessories

Hand-Held Remote Control

Man with Hand Held

Our most popular CNC accessory, now only $485.00! Almost every customer orders one with their CNC Masters Milling Machine.

Our exclusively designed Hand-held Remote Control gives you greater ease in controlling the CNC Jr., Baron, MAX, or Supra during initial setup as well as during the operation of the machine without using your computer keyboard. Most importantly--you can jog your axes while never having to remove your sight off the part. Machine simple slots, do profiles, and drill holes without booting up your computer.

The Hand-Held Remote features:

  • Knobs for spindle and feed speed control
  • Joystick to jog any of the selected three or four axes which allows the CNC Jr./CNC Baron/CNC MAX/CNC SUPRA to be operated without having to touch your keyboard or manually cranking the Hand Wheels on the motors.
  • Micrometer wheel which is located on the bottom of the remote. This feature allows you to position any axis in a minimum increments of approximately .0002" and two added multiple selections to move medium speed and faster speed.
  • "GO" button from where you can run your program loaded on the host computer.
  • "ZERO" button which allows you to remotely zero any axis during setup.
  • Red "KILL" button is located at the top of the remote to be used in the case of an emergency stop.

The Hand Held Remote comes with Velcro on it back for easy mounting on the machine and plugs in directly into the Control Unit through serial port. It is worth adding this accessory to your CNC MASTERS Mill or it retrofit kits for its added convenience and time saving features.


 

Engraving Attachment


(Above) One of our oldest customers of roughly 12 years recently sent us these engraving pics from there CNC Jr. Milling Machine. Their testimonials are the kind that keep us happy and pushing to drive some of the best relationships in the business.


Engraving Sample Created through CNC Supra or CNC Jr Machine

With the CNC Jr., Baron, MAX, or Supra, there is no need to have a separate engraving machine. The optional engraving attachment combined with the 3-D machining ability of the CNC Jr., Baron, or Supra, offers engravers creative opportunities not possible before. Furthermore, with the 4th axis rotary table, you can now engrave on curved surfaces! For example, you could scan the autograph of your favorite baseball player and engrave it on a bat, or you could have a pool cue engraved with your own unique design. CNC MASTERS offers Three Choices:

CNC Jr/Baron Engraver Attachment
The engraving attachment, which is a 3/4 HP Router that has a maximum speed of 23,000 RPM, mounts on the same spindle axis. It can be quickly attached or removed with a single clamping screw. You will have 11" of throat space or distance from the table to your router to machine your intricate details on your part. The router comes with a 1/4" collet so any tool with a 1/4" shaft will work. You can also use a reducing adaptor from 1/4" shaft to 1/8" holder for your tools that have 1/8" shaft. (The Router Attachment is designed for the CNC Jr. or Baron Table Top Mill.)

AIR TURBINE Air Spindle Attachment (can be used for the CNC Jr, CNC Baron, CNC MAX, or CNC Supra Mills)
You also have the option of the Air Driven Spindle with a maximum speed of 40,000 RPM, for jewelry, mold making, and fine machining and engraving such as designing a three-dimensional face for a doll or action figure. The Air Driven Spindle requires your air compressor to go to 90 PSI at 3 cubic feet/minute of air volume to obtain maximum RPM and connects to your spindle with R-8 collet. The AIR TURBINE Model 625JS -- 3/4" shank, 1/4" collet size for cutting tools.

The jewelry design in this picture was from our satisfied customer in the jewelry business using the CNC Jr Mill and the Air Turbine Air Spindle. Design is by Nouveau, Inc. in Bersa, OH.

CNC SUPRA Engraver Attachment
You will find that the ease of use and extreme rigidity offered in its design will result in your ability to engrave a superior product using the CNC SUPRA Mill. This product will ensure your ability to machine units at far greater efficiency and cost effectiveness than comparable air driven units. The RotoZip® brand (Manufactured by BOSCH) is a proven workhorse capable of delivering the power and dependability that is needed in our modern machine shop environments. The RotoZip® runs at 30,000 RPMs. Because the unit mounts directly to the quill (Z axis), maximum rigidity is guaranteed. It also provides maximum distance to the table for ample machining space. The CNC SUPRA Engraver Attachment is designed for the user looking for a low cost solution for his/her engraving needs using the CNC SUPRA Milling Machine. (5 amp power, runs on 120v only, contains 1/8, 5/32, & 1/4 collets)

 

CNC Supra Mill with 4th Axis and Supra Engraver CNC Supra Engraver Attachment and Accessory

(above) These pictures were sent to us from another satisfied customer using the CNC Supra along with 4th Axis and Supra Engraver.

...."I decided to buy the rotary table at same time as the CNC SUPRA machine itself. Thank the
Lord 'cause about a month later I had a gear cutting job come in for 100 gears at $150 a pop! Paid for the thing 15 times over! The Supra Engraver was a great idea!"

4th Axis Rotary Table

4th Axis Rotary Table for CNC Mill

TRUE CNC FOURTH AXIS CONTROL!

The ability of our CNC Control Unit to interpolate one or multiple axis with the 4th axis 6" rotary table, offers more options for machining difficult parts. Our 6" rotary table can be easily jogged and has a minimum motion of 1/100 degree. It can be secured on a horizontal or vertical position. The fourth axis motor is the same as the X, Y, Z motors which are size 34 with 1200 in/oz. of torque and is programmable in the same manner as the X, Y, Z axes. The the motion of the fourth axis can be interpolated with the X, Y and Z. The rotary table is easily removable from our cnc mills when three axis machining is needed only.

Quick Tool Change

Tool change with height compensation. With the CNC Jr., Baron, MAX, or the Supra you can machine production parts that require several tool changes. You can program up to ten different tools. The MASTER software will automatically adjust the Z axis for each tool change. The tool height compensation complements our manual quick tool change system. It only takes a few seconds to release and replace a new cutter from the master holder. This smart investment will pay off in no time. CNC Masters is proud to bring you two options to choose from, the quick tool change system by Royal Products or quick tool change system by Billet Designs.
