CNC SUPRA Vertical Knee Mill Features
The SUPRA Vertical Mill is designed to work with 64 bit operating systems: Windows 7, 8, or 10 through your standard USB port.
This Knee Mill features Powerful X, Y, and Z-axis micro-stepper motors are size 34 with 1200 in/oz. of torque. Stronger torque coupled with micro-stepping motion keeps the CNC Supra from losing steps and performs as accurate as a servo system.
The minimum possible motion for the SUPRA Vertical Knee Mill is .0002” with a minimum speed of 0.05” per minute. The maximum speed is 100” per minute on your Rapid Settings with ramp down effect to keep the machine from jerking.
X & Y Zero Backlash Ball Screws with pre-loaded ball nuts to eliminate play on the table travel, and give precision machining
X & Y Direct Drives–no belts to adjust. This results in smoother operations and ensures accuracy unlike bipolar, 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.
The SUPRA Vertical Knee Mill features Z Axis Zero Backlash Ball Screw with pre-loaded ball nut to eliminate play on the up and down travel of the Quill.
Quill Driven which is better than a knee driven Z axis; this maintains rigidity of the part being machined on three axis interpolation.
This Knee Mill 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.
Full 3 Axis or optional 4 Axis coordinated motion control. True Interpolation.
Limit Switches on all extreme ends of X, Y, & Z travel allowing you to confidently test your program without having to worry about an axis travel to its end and causing damage to machine.
Tool Height Compensation with Automatic Quill Retraction for easy R8 collet tool change
Tool Cutter Radius Offset Compensation
Run your tool path from any line on your program
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.
Hooks up to your PC, comes pre-built from the factory
The SUPRA Vertical Mill is Pre-engineered for you when it comes to pitch and resolution. No axis or motor tuning needed at setup. No additional parameters set-up required. Display resolution is 0.0001 micro-stepping travel. Just start using it.
Runs files from popular CAD-CAM softwares that produce standard G-Codes such as Mastercam, Surfcam, etc to your knee milling machine and engrave intricate and detailed parts at your command
Load DXF and IGES files from graphic programs such as CorelDRAW into CAM softwares to machine or engrave detailed parts from scanned images
Digital Read Out Display of your X, Y, Z, (and optional W) counters on your computer screen in INCHES or MILLIMETERS using your PC mouse, keyboard, or our optional Hand Held Remote Control.
Easily build a file of commands such as drilling operations to machine simple parts without the need to learn or use a CAD-CAM program
Can add a power feed on the knee lift, engraving attachment, fourth axis, computer control coolant assembly for the machine’s built-in tank, and quick tool change, from our line of accessories to the CNC Supra Vertical Mill
Optional “Computer” Controlled Variable Spindle Speed, save time without having to change the belt, and program your spindle’s speed in the Master Software. It also allows you to disengage power from the axis motors to allow for manual machining while still retaining computer control of the spindle. (Runs on single phase 240 vac.)
Easy user-friendly setup for any beginner or experienced machinist. Easy to learn and operate. See our testimonials.
Comes with Tool Box, front and rear chip guard, and a One-Shot Lubing System on the mill’s table ways and X & Y ball screws.

Unlimited “life-long” operational Tech Support step-by-step trouble shooting and walk-through process by email or phone support Monday-Friday PST during normal business hours for as long as your company owns the machine.
Easy to repair, replace parts, and maintain unlike costly servo systems which need to be serviced.
Free Master Software Updates upon request upon request for as long as the hardware can support it.
Your choice in 2 HP Spindle Motor 8 speeds, or 3 HP computer controlled variable spindle speed. Save time without having to change the belt, and program your spindle’s speed in the Master Software through G-codes, simple english conversational commands, or on/off with your PC mouse.

Thank you for taking the time to view the exclusive CNC Supra vertical milling machine, engineered and manufactured by CNC Masters incorporated in the USA. CNC prides itself in offering high quality CNC milling machines at competitive prices.
Many satisfied customers in the USA and around the world are enjoying the numerous uses of the CNC Supra milling machine. Because of its unique turn-key design, the Supra mill allows the novice or experienced Supra user to quickly gain control and master its operating features saving the user valuable time without on-site training. This is especially important if the user is under pressure to quickly prototype a part or has promised customers a quick turnaround.
The CNC Supra can be used for primary or secondary operations, prototyping or even mass producing a part for a client with materials as soft as foam, wax, plastic and wood to as hard as aluminum and even titanium and steel. Unlike other CNC milling machines, the CNC Supra does not require an advanced technical setup of the controller or software.
Overall, the CNC Supra milling machine is a ridged, simple automated system designed for the user who needs easy to use features and desires to design two or three dimensional applications immediately. You can jog your accesses with the touch of your PC mouse, keyboard or optional hand help remote control. You have feed control, relative control for exact driving distance of each access, optional cooling control and optional spinal speed control as well.
The CNC Supra is a versatile machine with X, Y and Z precision preloaded ball-nuts anti-backlash ball screws for precise machining of parts, detailed fine engraving with our engraving attachments and has true forth access optional control as well. The CNC Supra mill can accept simple English commands for quick and easy tool path programs or if you are cutting complex parts such as these, the Supra can accept g-code files from popular cad cam software’s as long as the user obtains the proper post processers from them.
In this demonstration we are showing a complex acorn three-dimensionally shaped part of a mold being machined from a g-code file generated from a popular cad cam software. You will note the complexity of this design by its many circular patterns and the horizontal and vertical planes. Using aluminum, this part is machined in three separate programs. The first program is a roughing tool path using a half inch flat cutter. The second program requires a quarter inch flat cutter for finished roughing and the last program will complete and finish the part using a quarter-inch ball cutter. For the sake of time, we are phasing in and out to show you the significant advances of all three programs as the CNC Supra machines the part noting the accurate interpolation of its three axis’s.
If you are interested in the CNC Supra mill, we would love to earn your business. Please, feel free to correspond with us at firstname.lastname@example.org or call us (number located on our website) should you have any questions or would like to receive a quote.
