TRAKing Pat gives an overview of our CNC knee mills.
Only TRAK Knee Mills featuring ProtoTRAK CNCs are factory-integrated by us, the manufacturer of the control. That means an outstanding product and one source of parts and support. You will never be shuffled between machine and CNC supplier; the entire product is our responsibility.
Our track record proves you can rely on us to live up to our responsibility to you.
The ProtoTRAK® KMX is the best CNC TRAK has ever made for knee mill applications. With the advanced technology, power and flexibility of the KMX, you can accomplish anything from quick manual jobs to complex profiling.
The K3 KMX-3 uses a quill drive for 3-axis machining. The mill can be run manually, or as a 2-axis or 3-axis CNC. Manual quill control is accomplished with electronic handwheels. The K3 KMX-3 is the most versatile of our knee mill machines. For most 3-axis machining applications however, we highly recommend our TRAK Bed Mills.
