There's nothing quite like fabricating your own custom designs using a CNC mill. We've recently started carrying these great CNC conversion products from PROMiCA of Australia, which are designed for seamless integration with the popular and cost-effective X3 and Super X3 Mill. This family of mill can be readily purchased from the following locations:

• Super X3 at Grizzly
• X3 at Grizzly
• X3 at Harbor Freight (Identical to the Grizzly X3 in dimensions, although their website seems to suggest otherwise)

The CNC conversion kit we carry will allow for complete computer control of the otherwise manual mill. While a handful of CNC conversion kits for this mill exist, the kit and components we carry are superior for the following reasons (among many others):

• Kit provides complete solution - no hunting around for compatible components
• Simple and quick to perform the conversion
• Detailed technical manual (including assembly photos) included. Manual is also in layman's terms meaning someone with no experience with a mill could install it.
• No modifications needed to the actual mill
• Very low profile - protrudes less than original mill handles
• Fully configured for 120VAC and shipped from our US location (other voltages available upon request)
• Under normal operating conditions, accuracy and repeatability should be under 0.001”
• Kit is nearly waterproof. Motors can stand all the flood coolant (even water-based) you can give it and the wiring is protected by loom tubes or HDPE covers.
• Ballscrews are coated with managanese phosphate which retards corrosion.
• Quality Australian workmanship
• Customer Support - we are always available by email, phone, or through the PROMiCA mill kit forum to answer any questions.
• Increased X and Y travel - about 1" on Y and 2-3" on X axes.
• Professional look - something you will be proud to show off to anyone.

There are many other great features and details. If you would like more information, visit the PROMiCA website, email us, or call for details.

This kit contains the X+Y+Z axis hardware, including plates, brackets, leadscrews and ballnuts, 20XL pulley on leadscrews, and the stepper motors with 10XL pulley, stepper wiring with loom tubes, timing belt for each axis

This kit contains the X+Y+Z axis hardware, including plates, brackets, leadscrews, ballnuts, 20XL pulley on leadscrews, 10XL pulleys for motors (drilled to 1/4"), and timing belts for all axes.

With the single ballnut on the conversion kit (the default), backlash averages about .003". With the double ballnut option, backlash can be reduced to zero!

The standard X3 allows for only 2000 RPM at the highest speed. Promica now offers an easy to install kit which will allow the spindle to run at 4000 RPM! This upgrade is ideal for those who wish to use very small cutters or engraving tools. The upgrade uses the existing two setting gearbox on the X3 but changes the setttings to 0-2000 RPM and 0-4000 RPM. The mill should still use smaller bits at very high RPM.

This 4 Axis intelligent controller comes with 3 axis cards to drive the PROMiCA 3-axis CNC mill. It can be expanded to a 4-axis controller with the addition of an axis card available on this page. The controller has low-level input buffering that allows it to work with most computers, including laptops (although not recommended). The controller will work with most CNC software such as Mach3, TurboCNC, etc. which is free of charge at machsupport.com. It comes equipped for 120VAC power supply.

This card allows you to take full advantage of the 4-axis intelligent controller. It is inserted into the controller to add the 4th axis such as a rotary table.

Oftentimes, your project would be better suited for a slightly larger mill. It can be annoying to have to turn the material around, refind the edge, and then continue running a milling program. The retrofitted Rotary Table was designed with those constraints in mind. Having a rotary table as a 4th axis decreases tooling and setup time significantly. The conversion kit is low profile (as are all other conversion kits we offer), making a smooth integration with the rest of your CNC kit. The table can be mounted vertically or flat on the mill table without issue. We offer the rotary table in 4 options.

 

Turn-Key Solution: Includes everything - 6" Table, Hardware, Motor, pulleys, timing belts, home switch, cables, and Axis Card - fully assembled! All you need to do upon receiving the kit is mount the table, plug in the card into your controller, enable the 4th axis in your CNC software program, and you're ready to machine!

Hardware, Motors, Axis Card: Includes aluminum mounting plates, pulleys, timing belts, home switch, cables, stepper motor, and the 4th Axis card. Do-it-yourself assembly is a piece of cake with the Promica installation manual which is full of detailed instructions and actual assembly photos.

Hardware, Motors: Includes mounting plates, pulleys, timing belt, cables, stepper motor, and home switch.

Hardware: Includes mounting plate, pulleys (not drilled for adaptation to varying motors), timing belts, and home switch.
