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



  • Available on most TRAK lathes
  • Powerful but easy to learn and use 2-axis CNC, 3-axis DRO
  • Run in manual or CNC mode
  • Runs ProtoTRAK conversational language, G-code, CAM, DXF converter and Verify Machining  Simulation software 
    Indexer compatibility for high-mix, low volume work

ProtoTRAK SLX is used on


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

Just Program the Part Geometry and Leave
the Tool Path to Cycle

With most CNCs you must define your part in terms
of tool path. But with the powerful cycle capability of
ProtoTRAK lathe CNCs, you simply define your part
geometry and the dimensions of your stock. The tool
path is generated automatically.

Just a few simple inputs in the powerful Cycle event...

...and the hard work of defining the tool path is done
for you automatically.


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.


Easy, Convenient Lathe Tool Setting
Accurate tool setting is easy. Tool data may be saved for use on different programs and even applied to manual work in the DRO mode.

List-Step Graphics
With a single button push, you can look at a full screen view of what you have programmed so far. From there, you can use the list step graphics to isolate program problems.

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.

Tooling Choices (Turning)
The ProtoTRAK can be easily programmed to utilize manual or automatic tool changes

Single - manual changes
Gang - set up and run jobs with gang tooling
Indexer - choose between option 4- or 8-station

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.

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.
