Used CNC Knee Mill Retrofit - A.G.E.

Used CNC KNEE MILL RETROFIT - A.G.E.


Shops that make parts in small quantities have a unique problem.  For most of these jobs, a "full-blown" CNC is not useful because the required programming and set-up takes longer than making the part on a manual machine.  At the same time, making parts on a manual machine is not very productive since it requires time-consuming set-ups and repetitive positioning - low value tasks for some of the most expensive people in your shop!
The TRAK A.G.E. is the solution to this problem.  It makes skilled people more valuable by making them more productive.

Used TRAK A.G.E. - what makes it the best possible CNC for small lot milling:

  • CAPABLE - it has the capability to machine arcs, diagonals, and pockets like sophisticated CNCs, eliminating the manual set-ups of rotary tables and sine plates.  Interface with off-line CAD/CAM systems enables you to run the most complicated parts.
  • FLEXIBLE - easy transition between manual and two or three-axis CNC operation as required by the task at hand.  The machinist is never stuck with doing things the "CNC way" if manual is better.
  • EASY TO USE - made for machinists to use on the shop floor without the extensive set-ups required of a production-oriented CNC.  Even a simple task like drilling holes is done quicker by eliminating the repetitive hand cranking between locations.  
  • The AUTO GEOMETRY ENGINE - embeds CAD capability in part programming, making programming easy by eliminating the need to calculate print dimensions.  

Used TRAK A.G.E. 2 - TWO-AXIS CNC, THREE-AXIS DRO
The TRAK A.G.E. 2 is a CNC package designed for milling parts in small quantities.  It is a complete retrofit system for a manual milling machine.

CONTROL
All the capability you need in a system that is easy to learn and use.
SERVO AMPLIFIERS/MOTORS
Power enough for any cut within the machine's capabilities.
CLOSED LOOP FEEDBACK
DRO encoders on the table and saddle work with motor encoders to provide the CNC with complete feedback of motor motion and actual machine position.
BALLSCREWS
Installed in the table and saddle to eliminate backlash and provide smooth, long lasting operation.
ALL HARDWARE
Including pendant arm, E-stop switch, handles, brackets, bearings, nuts, bolts and cable ties.

Used TRAK A.G.E. 3 - ADDS THREE-AXIS CNC
The TRAK A.G.E. 3 may be used as either a three-axis CNC or a two-axis CNC, a simple control selection loads in the capability you want.

Z-AXIS DRIVE ASSEMBLY
Including motor, encoder and ballscrew is installed on the head.  This assembly drives the machine's quill when operating as a three-axis CNC.  The motor is easily disengaged in order to operate the system as a two-axis CNC or manually with DRO.


AUTO GEOMETRY ENGINE (A.G.E.)

For the shop floor, Geometry-based programming is vastly superior to old-fashioned Tool Path programming.  But however convenient the programming system, incomplete print data still can present the chore of calculating points - unless you have the Auto Geometry Engine.  The Auto Geometry Engine is powerful  software that works behind the easy-to-use Geometry-based programming of the TRAK A.G.E. Control, and it is called up when needed by pressing "A.G.E. PROFILE" at the SELECT EVENT prompt.  With the Auto Geometry Engine you program the successive mill and arc events that make up the part profile by entering only the dimensions that are available on the print.  The Auto Geometry Engine will do the calculations for you, not as a separate operation, but WHILE YOU PROGRAM.





APPLICATIONS

Thousands of shops have already discovered the value of the investment in this technology.  They use their TRAK controls for the applications shown here:

Used TRAK A.G.E. 2
ideal for lots of 1 to 10, where the constant attention of the machinist is required

  • TOOLING, FIXTURES - where there is a lot of machinist input in the design of the part.
  • MOLDS, DIES, EDM ELECTRODES - problem solving is required during machining.
  • PROTOTYPES, MODELS - changes and modifications are anticipated.
  • MAINTENANCE, REPAIR - often with no part drawings or incomplete part specs.
  • SPECIAL MATERIALS, INVESTMENT MOLDS - constant attention is required.

Used TRAK A.G.E. 3
useful for lots of 10  and up, where the additional setup and programming of the Z axis is worthwhile.

  • LIGHT PRODUCTION - skilled input at first, part changing by less expensive personnel later.
  • SMALL LOTS, SECOND OPERATIONS - jobs that are marginal for an expensive machining center.
  • SOME MOLD MAKING - complex Z contouring.
  • REPEAT JOBS - for JIT inventories.
  • HOLE DRILLING, MULTIPLE PASSES - repetitive operations that can run partially attended.

PROGRAMMING CANNED CYCLES

Posn/Drill - single point
Bolt Hole - series of points evenly spaced around a circle
Mill - straight line in any direction
Arc - any portion of a circle
A.G.E. Profile - series of connected lines and arcs defined with limited print data
Pocket - a rectangle, polygon, circle or irregular shape and all the material inside, includes finish cut
Frame - a perimeter of a rectangle or circle, includes finish cut
Sub - repeat of programmed events with or without offset, mirror image or rotation

FOR THE A.G.E. 3, ADD:
Drill and Bore routines
Helix - for threading
