Polishing achieves the most precise surfaces of all finishing
methods. Parts move between horizontal rotating plates as
an ultra fine free abrasive causes micro inch cutting at
a highly controlled rate. Polishing is typically preceded
by another finishing process such as grinding, fine grinding
/ flat honing, or conventional flat lapping. Capabilities
Lap Tech Industries has years of polishing experience and
the equipment to handle a wide variety of parts.

tolerances are approximate. Actual tolerances are dependent
on part size and shape.
Ideal
for all types of components
Polishing is ideal for all types of metals, ceramics, plastics, glass, carbon,
hard anodized surfaces and other materials. Components of most sizes and shapes
can be quickly and easily processed, including rings, seals, heat sinks, gears,
bearings, rollers, slitter knives, cutting tools, silicon wafers and others.
These components are used in a variety of devices including precision pistons,
automotive sensors, valve, gear pumps, rotary pumps, faucets, computers, telecommunication
devices, optical equipment and virtually any product with a sealing surface.
Features
and Advantages
- High Precision
Parts
can be polished to extreme tolerances including flatness
to within .025 microns
and dimensions to
within .05 micron.
- Surface
Finishes
Surface smoothness
of 0.1 micro inches and better can be reached on a repeatable
basis.
- No Stress
The
highly-controlled micro inch cutting eliminates stress on
the work parts, ensuring
that even the
tightest tolerances are consistently achieved.
