TRAK 3-Axis CNC Retrofit

Three-Axis CNC

Retrofits using the KMX CNC are available as three-axis CNCs, with a quill drive for Z-axis machining. The mill can be run manually, as a two-axis or three-axis CNC. Manual quill control is with our unique Electronic Handwheel.

Note: For most three-axis CNC applications, we highly recommend TRAK Bed Mills.

3-axis retrofits are not available with the RMX at this time.
