TRAK Knee Mill 3 Axis CNC

Three-Axis CNC

TRAK Knee Mills with the SMX and 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 our TRAK Bed Mills.

Not available for the ProtoTRAK EMX.

Coolant Pump

The optional coolant pump is mounted on the back of the machine column. It is wired into the electrical panel for operation through the Accessory key on the CNC front panel. A manual switch is provided for ProtoTRAK EMX and SMX CNC two-axis models, or if Auxiliary Function option is not ordered.

Limit Switches

Switches and brackets to set for maximum travel limits. Tripping the switch will cause the servo motors to shut down. Note, limit switches are not especially recommended. The system software monitors voltage intensity and will shut down the servos if it detects excessive force.

Auxiliary Functions - Knee Mills

The Auxiliary functions provide program control of spray mist or coolant, spindle off, and interface to a programmable rotary table or indexer.

Not available for models K3EMX and K3SMX knee mills or 2-axis retrofits.
