Product BrochureThe CNC Jr. delivers quality and accuracy for LESS! Why spend thousands on a manual-milling machine, when you can let automation technology do the work for you? IT'S TURN-KEY, EASY TO LEARN, AND EASY TO OPERATE!
The CNC Jr machine and controller are built to order and stock in-house in the USA. We do not buy and re-sell our CNC Driving System. So we'll never bounce you to a third-party vendor for limited support to either their controller or another vendor's machine. WE SUPPORT THE COMPLETE CNC Jr MILLING CENTER INCLUDING ITS OPERATIONAL SOFTWARE BY PHONE OR EMAIL.
The CNC Jr. Table Top Mill is a versatile bench top mid-size CNC mill made for primary or secondary CNC machining applications. This CNC machine is intended for the user who needs the ability and performance of a CNC Bridgeport-type size machine without taking up floor space like larger CNC machinery. The CNC Jr. Table Top Mill is a great purchase for small machine shops, research institutions, colleges, universities, high schools, engineers who need to quickly prototype 3D parts, and one-man operations who need to mass produce hundreds of the same single part in their home garage-turned-shop. The CNC Jr Mill makes a great investment tool for business owners who would rather save money by machining their own parts instead of contracting the order out. Because of its size, the CNC jr can fit in areas where space is limited, yet can machine just about any application within 19” and 7”. SAVE YOUR BUDGET, TIME, AND BEGIN CUTTING PARTS THE SAME DAY! The CNC Jr. is made in the USA combining parts made in the USA and abroad allowing us to bring the savings to you. THE CNC Jr. IS TESTED FOR QUALITY AND PERFORMANCE IN-HOUSE IN AZUSA, CA USA.
- Works on operating systems: WINDOWS VISTA AND XP on USB.
- Powerful X, Y, and Z axis micro-stepper motors are size 34 with 1200 in/oz. of torque. Stonger torque coupled with micro-stepping motion allows the CNC Jr to perform accurately without losing steps. The minimum possible motion is .0001” with a minimum speed of 0.5” per minute. The maximum speed is 50” per minute.
- Full 3 Axis or optional 4 Axis coordinated motion control on bipolar motors--far superior over unipolar technology when it comes to torque and power. True Interpolation!
- Hand-Wheels on each axis for manual option machining with motor disengage feature to retain spindle speed control (applies to the CNC Jr. with variable spindle speed control)
- X & Y Axes Zero Backlash Ball Screws with pre-loaded ball nuts to eliminate play on the table and saddle travel, and provides precision machining. These custom-made precision ball screws allow for precision conventional and climb milling operations and accurate circular and contour cuts without time consuming setups.
- Z Axis pre-loaded arrangement to eliminate backlash on the up/down travel
- X & Y Direct Drives--no timing 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.
- 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.
- 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 Diameter 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, and is completely tested before shipping out.
- 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 such as drilling operations without the need to learn to use a CAD-CAM program

The CNC Master Software:
Click here to view our full specs on the CNC Jr 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 and XP (min 32 bit). It communicates with the CNC Control Unit through USB port the standard in computer communication. The MASTER software features a main windows panel interface that will allow the novice user 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 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.
Other Master Software Features:
- Relative driving of any precise distance with one click +/- on the chosen axis
- Tool Height Compensation with Auto Quill Retraction for easy R8 Collet change out
- 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 Jr. or the CNC SUPRA with POPULAR CAD-CAM SOFTWARES!
These pictures were given to us by Chris Twine of MA who produced this part for his custom made motorcycle using the CNC Jr Mill.
With the included G-CODES FILE INTERPRETER, the MASTER software can run files generated by many advanced CAM software packages, like the 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 Jr., 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)
G03 = Circular interpolation (CCW)
Format: X__Y__I__J__ I,J are relative distance from start to center. Incremental Z can be added for helical designs.
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____

Many of the parts I have produced on much larger and more expensive machines could have been produced on the CNC Jr...The benefits of the CNC Jr. are less cost and less size. When we are looking at new machinery, we sometimes forget that the concrete these machines sit on is not free. --John Kitchens Dallas, Texas
These pics were given to us from Avro Enterprises in Ontario, Canada. He said it took him only 15 minutes to machine these two aluminum frames (third pic on right) using the CNC Jr desktop milling machine.
