For second operation work and/or stand-alone applications.


  • Portable and ships with pallet jack
  • Integrated Jergens Ball Lock System
  • Simple Conversational Programming
  • 3-Axis simultaneous interpolation
  • G code compatible
  • Automatic fixture offsets
  • Indexer compatible


Designed to be easy to learn, use, and move, the TRAK 2OP is the first portable VMC designed for second operations work. It allows a second spindle to be brought quickly and easily to operators idled by the cycle time of their primary machines so that both first and second operations can be run simultaneously. This arrangement makes practical, for the first time, the creation of work cells in high-mix, low volume shops. The result-part cycle time is reduced and output is increased at no additional cost in labor.

For a cost effective, high-mix, low-volume work


  • Integrated Jergens Ball Lock System
  • Simple Conversational Programming
  • 3-Axis simultaneous interpolation
  • G code compatible
  • Automatic fixture offsets
  • 4th Axis Compatible


Designed to be easy to learn and use, the TRAK LPM incorporates technologies to markedly reduce the changeover times that plague high-mix, low-volume shops. It is the only VMC to integrate the machine, control, fixtures, and tool offset measurements into one complete system. This means that it doesn’t require expensive probing systems that consume spindle time to measure offsets. It also means that it doesn’t require a room full of special fixture to facilitate quick changeovers.

Easy to use yet full CNC functionality


  • Easy to learn and remember all the features
  • We recommend this control when most of the work for the machine is simple
  • Great for shops where different people use the machine occasionally
  • Vo Techs love this CNC for teaching conventional milling and introduction to CNC on the same machine


ProtoTRAK Retrofits


Make your manual machines more productive

The more frugal you are, the more painful it should be to watch your people spend their time unproductively. The cost of the ProtoTRAK CNC is trivial when compared to the cost of the person standing in front of the machine. If you are going to keep and use the machine, retrofit it.

Even a machine that has some wear can be a good candidate for a retrofit. Ballscrews will be installed in the table and saddle and electronic machine tool error calibration and backlash compensation routines help maintain accuracy. If the head is in good condition, you probably have a useful machine.

The retrofit kit includes everything:

  • Motors
  • CNC Control
  • Hardware
  • Ballscrews
  • Fasteners
  • Cable ties

It is installed in your shop in about a day by a factory-trained technician.
Custom kits for dozens of machines are available in either 2 or 3-axis CNC.

You shouldn’t stop investing in productivity until all your machinists are working as efficiently as possible. Retrofitting can be a cost-effective way for you to reach that goal.
