Precision Polishing

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.


Lap Tech Industries has years of polishing experience and the equipment to handle a wide variety of parts.

Listed 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.
