Kemet Portable Hand 3 Lap Kit for Lapping and Polishing

Portable Concentric Grooving Lapping Kit

Hand lapping uses the same principles as machine lapping with respect to abrasive grade / plate selection / plate flatness, but with the following exceptions

  • Lapping plate is kept stationary
  • Components are moved by hand in a figure of 8 action
  • Diamond compounds or liquid diamond can be used

Leaking pumps, valves and seals cause many problems, leading to wastage, poor performance, unnecessary costs, even health hazards. Kemet Portable Lapping Kits enable refurbishment to be carried out on site, reducing expensive downtime. Components manufactured from ceramics, tungsten carbide, stellite, brass, steel, silicon carbide, carbon, ni-resist etc, can be lapped and/or polished by hand in minutes rather than hours. The kits are also ideal for low volume production, where it is not economical to purchase a lapping or polishing machine.
