Petty-Thompson Used CNC Knee Mill
Retrofit - Proto Trak

| Used CNC KNEE MILL RETROFIT - PROTOTRAK |
|
| Work that is done on manual
knee mills presents a problem. The jobs are usually
simple and required in small quantities, therefore unsuitable
for production-oriented CNCs. At the same time,
making parts on manual machines 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 ProtoTRAK has been
solving this problem for more than ten years. It
has the features machinists need to save time, while avoiding
the complexity normally associated with CNCs.
- 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.

Applications -
Thousands of shops are already using ProtoTRAKs for the two
and three-axis applications shown here.
Used ProtoTRAK
M2 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 LECTRODES - 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 ProtoTRAK
M3 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.
SOFTWARE
Diameter
Tool Compensation allows programming of the actual part
rather than the center of the tool path. Circular
Interpolation makes arcs and any size hole easy to do with
standard tools. Linear Interpolation to machine
diagonals at any angle. Conrad provides automatic
corner radius programming for inside or outside corners with
one data input. Incremental and Absolute programming
can even be mixed within a single event. Error
Messages to identify programming mistakes. Fault
Messages for system self-diagnostics. Program Down
loading from offline CAD/CAM systems. Mirror Image
and Rotation of programmed events. Part Graphics
displayed before machining or during program run (real
time). Look a single button press to view graphics
during programming. Math Help for finding points in
prompted format with graphical representation of
prompts. Teach for programming manual
moves. Machine Tool Error Compensation and Backlash
Compensation custom set on your mill after
installlation. Scaling of print data.
FOR
THE Used ProtoTRAK M3, ADD:
3-Axis circular and Linear
Interpolation; 3D Graphics. Helical
Interpolation. Tool Length
Offsets.
HARDWARE
Simple Installation in
your shop and on your mill. Digital Servo Amplifiers custom
designed for ProtoTRAK operation. D.C. Servo Motors rated
at 280 in-oz. continuous torque are twice that
required. Precision Ground Ballscrews in the table and
saddles. Modular Design simplifies service and maximizes
uptime. 115V/60Hz/15 Amps. Feedrate Override of
programmed feedrate and rapid. Polycarbonate Sealed
Membrane Keypad and Gasket sealed Control Enclosures to lock
out contamination. 9" CRT. Built-in Floppy Disk Storage
for part program. RS232 Port for Interface with
computers.
FOR THE Used ProtoTRAK, ADD:
Z-Axis
Ballscrew and Motor assembly Dual Floppy Disk
Drive
