"For those of you out there who are considering a
conversion of any Bridgeport or Bridgeport clone knee mill, please allow me to advise you to give serious consideration to the CNC Master's kit. It is a complete kit and is extremely well designed with great consideration given to making it easy to assemble with a minimum of work to the mill itself. Working by myself and following the instructions, I had no problems of any kind with respect to alignment or any other issues. In running the mill, repeatability is as advertised as is accuracy. My mill is equipped with X and Y DRO and the coordinates called for on the computer are matched by the DRO indications within 2 to 4 ten thousandths EVERY time! Measurements of repeat runs are even better than that! I searched a long time for a kit and given CNC Master's design and Mfg quality and including ease of conversion I could not find anything that came even close to matching it. Neither could I
find anything close for this price. Lastly, CNC
Masters has been one of the most accommodating companies I have ever dealt with. All things considered, this was one of the best decisions I have made and a huge step in having more capability."
-Michael Morris, Marysville CA

Your Three Axis Kit comes "COMPLETE" with:

Powerful X, Y, & Z micro-stepper motors. The minimum possible motion is .0001” with a minimum speed of 0.5” per minute. The maximum speed is 50” per minute. X and Y are size 34 pre-wired with 1500 in/oz. of torque and the Z is size 34 pre-wired with 1200 in/oz. of torque.
X, Y, Z Zero Backlash Ball Screws with pre-loaded ball nuts to eliminate play on the table, block, and quill travels to provide precision machining.
The Master Operating Software which can operate on your PC Windows XP/VISTA computer through USB port. Click here to view our full specs on the CNC SUPA Master Operating Software.

Tolerances:

Accuracy is +/- 0.003" in 12" (+/- 0.00025 per inch)
Repeatability is within 0.0005"
Resolution is 0.0002" of linear motion on the X, Y, and Z.

Features:

Home Reference Sensors on the X, Y, & Z which saves your home/zero position as the first line of your program. This feature allows you to quickly return to the home position on any program without having to manually zero your three axes again.
Tool Height Compensation with Automatic Quill Retraction for easy R8 collet tool change
Easy to Use Jogging Features and Feed Control
Jog-Input Command automatically writes each line of your toolpath as you manually jog each axis by pc mouse, keyboard, or the optional hand held remote control joystick to save as a program for repeat use.
Software Power Feed capabilities on X, Y, Z, and W with one click of the pc mouse for exact relative driving distance.
Run your tool path from any line on your program
3 Axis or 4 Axis CNC Control Unit which mounts on the back of your mill and drives your system.
Master Software with G-CODE file interpreter; works with Windows XP to VISTA.
Hand-Wheels for each axis. These hand-wheels mount directly behind each motor, giving you manual option for the machining of quick and simple parts that do not require programming.
All hardware supplied with easy-to-follow instructions for the conversion of your mill.

CNC Machine Tools CNC Supra Milling Machine Mill Machine Control Unit

Other Great Features that comes with your KIT:

X & Y Direct Drives--no belts to adjust. This results in smoother operations and ensures accuracy unlike pulley and belt drive methods which can cause the belt to buckle causing inaccurate results. This unique design of direct drive keeps the user without having the need to change the belt or adjust as it wears down.
No bulky large motor brackets that house the belts on the X & Y
Full 3 Axis coordinated motion control, or hand-operated control
Easy-to-follow instructions with pictures to convert your mill
Easy mounting of Z Axis bracket ball screw motor assembly to Quill with alignment reference guides for Quill Drive
Easy precision alignment setup of the X & Y ball screws to your machine
Control Unit mounts on side of your machine and hooks up to your PC
Pre-engineered for you when it comes to pitch and resolution. No additional parameters set-up required. Display resolution is 0.0001 micro-stepping travel.
Since this is not a complicated servo system, you do not need to tune up anything for optimum performance. Our design uses a micro-stepping system "already" pre-designed for optimum performance.
Ready-to-Operate System: As soon as all hardware conversion on your mill is done, install the software on your PC, plug the Control Unit to your PC, turn it on, and you are ready to program your parts to machine!
Runs files from popular CAD-CAM softwares that produce standard G-Codes such as Mastercam, Surfcam, etc to machine and engrave intricate and detailed parts
Load DXF files from graphic programs such as CorelDRAW into CAM softwares to machine or engrave detailed parts from scanned images
Easily build a file of commands to machine simple parts without the need to learn or use a CAD-CAM program
Can add hand held remote control, engraving attachment, fourth axis, quick tool change, computer control coolant assembly--providing your machine contains a built in tank from our line of accessories to your newly assembled CNC Mill.

The instructions will also show you how to install all the other features that are included in your kit such as your ball screws and Control Unit. IMPROVE THE PRODUCTIVITY OF YOUR MILLING MACHINE with automation technology! Why spend thousands more on a new CNC Milling Machine if you already own a bridgeport-type vertical knee mill 9x42 or 9x49 table, 12" knee? Put it to use, and design parts with ease using CNC Masters technology! All components and accessories on the CNC SUPRA Retrofit Kit are individually tested for quality assurance before shipment.

If the top part of the Head comes forward as in the third picture above, the Z Axis Motor and Bracket can be mounted reversed so it does not cause interference with head of your machine. A simple reversal of the motor wires will allow you to retain the correct pos/neg motion. The top and bottom reference faces can have an un-even surface as shown in the pic above or have a flat surface as well.

In approximately 8 hours you should be ready to operate your newly retrofitted milling machine with CNC power!*

Hand Held Remote Control Also check out our line of accessories such as our own exclusively designed Hand-Held Remote Control which allows you to move your newly converted CNC machine's three or four axes with ease by the touch of a joystick! Only $485.00 more!
