High-end CNC for one-off and small lot work

  • Available on TRAK mills and as a knee millretrofit for over 40 makes and models
  • Powerful but easy to learn and use
  • 2 or 3-axis CNC, 3-axis DRO
  • Run in manual or CNC mode
  • Runs ProtoTRAK conversational language, G-code, CAM, 2 and 3-D CAD converter software, and Verify Simulation software*

* Some features are optional

ProtoTRAK SMX is used on:
ProtoTrak SMX CNC retrofits
TRAK K3 SMX Knee Mills
TRAK Bed Mills


Best for these situations:


  • From "manual" work to parts with of moderate complexity (blended profiles)
  • Users will work on the same machine frequently 
  • Prototypes to small batch production
  • Productivity and continuous improvement are key objectives

Powerful Capability


Auto Geometry Engine
The Auto Geometry Engine (A.G.E.) is powerful software that automatically fills in missing print dimensions as you program. It is CAD capability embedded into CNC programming.
With A.G.E. you can make easy work out of programming incomplete prints or part sketches like the ones below. The A.G.E. doesn't take more time to use, it works automatically as you program.


Tool Path Graphics
The ProtoTRAK relieves you from the chore of programming the tool path, but you will still be interested in seeing where the control is planning to move the tool. Colors, error messages and selectable views make it easy to check your program before you machine.

Profiles and Pockets
Programming pockets and profiles of all shapes is a breeze with powerful canned cycles.

The ProtoTRAK may be networked with other ProtoTRAKs or with a server. This allows you to file, share or back-up programs right from your machine. Centralized file management helps assure revision control. Efficient file-sharing allows collaboration without time spent communicating between departments.

Spreadsheet Editing
View data for your whole program all at once. Sort and make changes to whole groups of events with one press of a button. This is much more convenient than either moving through your program one event at a time or picking through a long list of G Codes.

Advanced File Management
The ProtoTRAK borrows the Windows® functionality and adds a couple of clever twists. File management is enhanced by the ability to access different drives, copy and rename files and look at the part graphics before opening the file. Backing up part programs is easy with the automatic back up routine.

Run-Time Clock
In the run mode, the ProtoTRAK will display the time remaining until the next time the control is programmed to stop for a tool change. You know how long it will be before the job will need attention from you.
