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.

Advanced Features - Knee Mills
Advanced Features with Verify incorporates 3D solid model machining simulation software that allows you to quickly and easily proof your ProtoTRAK mill programs prior to cutting chips.
Not available for the ProtoTRAK EMX.
Remote Stop/Go Switch
A hand-held switch to stop and continue program run.
Table guard with sliding doors to impede chips and coolant and keep the operator from the tool and workpiece during CNC machining. Interlock switch on the door interfaces to the CNC. DRO and TRAKing are allowed with the door open, but the door must be closed for automatic CNC operations in the Program Run Mode.
Bright, long-lasting LED work lamp with industrial-grade mount.
6″ Kurt vise and mounting hardware - model DX6. Opens to 9″.
The unique Fog Buster® non-fogging coolant sprayer precisely directs a fine stream of coolant to the tool and workpiece.
TRAKing® / Electronic Handwheels
The feel of manual control of real handwheels, but our electronic handwheels bring the power of the CNC to your fingertips through features such as TRAKing and DO ONE. Standard for TRAK DPM RX5 and TRAK DPM RX7.
Power Draw Bar
A Torque-Rite draw bar factory installed. May be ordered as CAT or NMTB/NST. Draw bar for CAT type is longer to fit into tool holders that have the tool changer grip, or retention knob removed.
A popular brand of glass scale mounted on the table and saddle.
DXF Converter - Mills
Import and convert CAD data into ProtoTRAK programs
DXF or DWG files
Automatic Gap Closing
Easy, prompted process you can do right at the machine
Not available for the ProtoTRAK EMX.
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.
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.
USB Memory - 2GB
The USB Memory option consists of an industrial-grade 2G Delkin® Thumb drive. Don't let the relatively small capacity fool you, this thumb drive is unsurpassed for reliability and speed of file access. It is the storage of choice for our own software engineers.
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.
Other Knee Mill Options
Networking Option — lets you connect your ProtoTRAK to a network of other ProtoTRAKs or offline computers. (Not available for the ProtoTRAK EMX.)
Auto Lubrication Pump — The auto lubrication for the ways and ballscrews is wired to operate while the spindle is running. Discharge times and intervals are set on the lube pump. (Not available for model K3EMX knee mills.)
