Used CNC Dual Purpose and Toolroom Mills

Used TRAK MILLING MACHINES


Factory fit CNC bed mills feature the TRAK Auto Geometry Engine three-axis or TRAK Auto Geometry Engine two axis a substantial upgrade to the knee mill design.  Both models are ideal for toolroom prototyping and light production milling.  Ideal when you want one machine for many different applications.  There is easy transition between manual two-axis CNC, three-axis CNC, and three-axis DNC.  Twice as heavy as standard knee mills.  More rigidity, stability, and capability.

Used TRAK DPM
...THREE-AXIS CAPABILITY


The TRAK DPM is the Dual Purpose Mill, to be used both as a Two-Axis and as a sophisticated Three-Axis Milling Machine.

USE IT AS A THREE-AXIS CNC MILL

When needed, the TRAK DPM operates as a three-axis CNC mill. The easy-to-use TRAK A.G.E. 3 gives you the capability you need in a CNC that is easy to learn and operate. Used this way, it is outstanding for light to moderate quantity production, as well as complicated three-axis geometry as in mold making.

CNC CONTROLLED Z RAM MOTION - For the Z axis motion the entire Ram moves up and down along the column, giving you rigidity and generous Z travel.

AUXILIARY FUNCTIONS STANDARD - The TRAK DPM comes equipped with auxiliary functions at no extra cost.  These functions allow automatic control of machine coolant and fourth-axis index functions from commands programmed into the control.

USE IT AS A TRM

The TRAK DPM can operate as a TRAK TRM with all of the features you see on the preceding page.  With a simple selection on the control, the machine operates as a two-axis CNC with the third-axis DRO.  You are never forced to program or set up a three-axis CNC when you don't need that capability.

DUAL INPUTS TO THE Z POSITION READOUT -  The Z axis position displayed is the sum of the motion of the ram (measured by a ballscrew encoder) and the quill (measured by a quill encoder).  In this way, the Digital Readout keeps track of both your ram motion and your manual quill positioning.

A TREMENDOUS VALUE

The TRAK DPM adds up to an exceptional value.  For a little more money than it costs for a good quality knee mill and control, you get:  a lot more iron than with a knee mill; a lot more simplicity than with a Machining Center; a lot more capability than with a two-axis CNC;  and more versatility than with any other alternative.

Used TRAK A.G.E. - THE DPM CONTROL
   ...VERSATILE THREE-AXIS CNC


The TRAK A.G.E. 3 gives you the capability you need in a three-axis control but without the complications found in other CNCs.

THE SAME EASE OF USE AS THE TWO-AXIS CONTROL, WITH THESE ADDED CAPABILITIES:

  • Three-axis simultaneous interpolation including helical canned cycles.
  • Advanced #D tool path graphics before you machine or "real time" during machining operations.
  • Easy transition between capabilities.  A single button press leads in the CNC you want to use - A.G.E. 2 or A.G.E. 3.
  • Optional DNC interface to run large CAM files or complex geometry.
  • Auxiliary functions to control coolant on/off, spindle off, shop air (for a spray mister) and generate a signal to a fourth-axis indexer as the part program runs.

Used TRAK TRM
            ...The two-axis CNC bed mill


The TRAK TRM is the best machine ever made for tooling, fixtures, prototypes, molds, models, electrodes and short run production.  MADE FOR MACHINISTS, NOT CNC OPERATORS.  The TRAK TRM is made for use by the skilled machinists that use knee mills now.  The machine retains much of the same feel of a knee mill and the control is easy to learn for people who know a lot about machining, but not much about computers.  The TRAK TRM makes machinists more valuable by allowing them to spend time solving problems instead of wasting time on manual set-ups or repetitive positioning.

FLEXIBLE OPERATION

  • AS A MANUAL MILL
    Manual operation is enhanced by three-axis Digital Readout, power feed and jog capabilities.  Ball screws in the table and saddle, and wide way surfaces make handle turning smooth and eliminate backlash for positive control.
  • AS A COMBINATION MANUAL/CNC MILL
    To eliminate a time consuming set-up in what would otherwise be a manual job, the CNC can be used for one operation and then the mill returns to manual control.
  • AS A SOPHISTICATED TWO-AXIS CNC
    The TRAK A.G.E. 2 control makes the most useful features of CNCs available for creating complete two-axis part programs.

Used TRAK A.G.E.2 - THE TRM CONTROL ...TWO-AXIS CNC

EASY TO USE

  • All programming in English - no G or M codes to learn.
  • Prompted data inputs - just follow the instructions on the screen.
  • Powerful Auto Geometry Engine - allows programming the part with available data.
  • Geometry-based programming instead of the tool-path programming of typical CNCs.
  • Canned cycles for milling arcs, diagonals, pockets and position drilling operations like bolt holes.

CAPABLE

  • Two-Axis Linear and Circular Interpolation.
  • Math help routines both for finding points and built into the Auto Geometry Engine to calculate unknown points.
  • Diameter cutter compensation allows programming of actual part rather than the center of the tool.
  • Mirror Image, Rotation and Repeats of programmed events.
  • Part graphics to show the entire tool path.  Can be used as a preview during programming or while you machine.
  • Communication with off-line computer systems for running CAM files or saving and receiving programs.
