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.
Thousands of shops are already using ProtoTRAKs for the two
and three-axis applications shown here.
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
- MAINTENANCE, REPAIR - often with no part drawings
or incomplete part specs.
- SPECIAL MATERIALS, INVESTMENT MOLDS - constant
attention is required.
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
Tool Compensation allows programming of the actual part
rather than the center of the tool path.
Interpolation makes arcs and any size hole easy to do with
