Specifications

The CNC Supra Features: 

  • WINDOWS INTERFACE.  Works on operating systems:  WINDOWS VISTA and XP on USB.
  • Powerful X and Y axis micro-stepping motors size 34 with 1500 in/oz. of torque and Z axis micro-stepping motor with 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 is .0001” with a minimum speed of 0.5” per minute. The maximum speed is 50” per minute.
  • 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.
  • 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.
  • 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!
  • Tool Height Compensation with Automatic Quill Retraction for easy R8 collet tool change
  • 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
  • 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 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 METRIC 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 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.)
  • 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.
  • 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.

The CNC Master Software:

3 Axis CNC Supra Mill

Click here to view our full specs on the CNC SUPA Master Operating Software

The CNC MASTERS Control Unit is controlled by the user friendly MASTER software, which runs on any IBM-AT compatible computer with at least 500Mhz and Windows VISTA or XP.  It communicates with the CNC Control Unit through the USB port that is the standard in computer communication. 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 runs standard G-code files from other CAD-CAM software such as SmartCam, SurfCam, etc.  The Master software also features its own programming language.  It uses plain English words, 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 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 REPEATABLE 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.

Other Master Software Features:

  • Tool Height Compensation with Auto Quill Retraction for easy R8 Collet change out
  • Relative driving of any precise distance with one click +/- on the chosen axis
  • Go From Line Command--allows the user to start his toolpath from any line on his program
  • Beep End Program--a beeping sound from the computer to notify the user that the job is done
  • Peck Drilling Cycle
  • Mirror Command--runs the opposite direction of the written toolpath.
  • Go Home--recounts its steps back to your Zero position
  • Saved Home Positioning--never lose your Zero position again when machining the same part
  • Pre-Set--allows you to begin machining at any given value on the X Y Z counters other than zero
  • Tool Radius Offsets
  • Intuitive Interface with axis jog buttons placed in the viewpoint of the cutter to avoid confusion of direction

USE the CNC SUPRA 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 BOBCAD-CAM or VisualMill 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 Supra, 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.

The Master Software supports these standard G-Codes and M-codes:

G00 = Position (Fast speed)

G01 = Linear interpolation (Feed speed)

G02 = Circular interpolation (CW)

Format: X__Y__I__J__ I,J are relative distance from start to center.  Incremental Z can be added for helical designs.

G03 = Circular interpolation (CCW)
G17 = Cancels G60 Command
G40 = Tool Radius compensation off
G41 = Tool Radius compensation left
G42= Tool Radius compensation right
G60 = Switch data from Y to W * radius factor

G70 = Input in inches           

G71 = Input in millimeters       

G80 = Cancel Peck Drilling Cycle

G83 = Peck Drilling Cycle, Format: X____Y____Z____R____Q____P____F____

G90 = Absolute move (Modal)

G91 = Relative move (Modal)

G98 = Return to initial point in canned cycle

G99 = Return to R point in canned cycle

 

M00 = Stop

M02 = End routine

M03 = Spindle on

M04 = Spindle off
M06 = Spindle reverse
M08 = Coolant on

M09 = Coolant off

M30 = End program
