Serving the Aircraft & Automotive Industry Since 1969 WORLDWIDE!

Established in 1969, Technical lapping are totally dedicated to the lapping industry. Our large and dedicated workforce combined with our specialist lapping technology means we are capable of handling a wide range of product sizes and materials. This no doubt accounts for the broad spectrum of industries that use our services on a regular basis. As an illustration we handle components for the aircraft, automotive (Including Formula 1 racing), engineering and electronics industries.. Lapping is ideal for close tolerance work. We can work to a flatness and parallelism tolerance of 0.05 micron and thickness to ± 0.05 micron (size and material dependant). We can achieve a variety of surface finishes, reflective or matt down to 0.007 micron Ra

Lapping is a cost effective method of machining where components are required to be flat, parallel, need controlling for size or require a fine, or specific surface finish. Lapping can be applied to a wide range of materials and components and the lapping process is used in a diverse range of industries.
Lapping is a precision process or combination of processes used to provide flatness, parallelism, size and surface finishes to extremely demanding tolerances. The process is a manufacturing method that employs particles of an abrasive material to remove stock from a surface. It is comparable to sanding or grinding, except that sanding and grinding use abrasives, which are fixed (bonded abrasives) whereas lapping employs abrasives, which are suspended in a liquid carrier, and are free to move about. Lapping is sometimes referred to as 'Free Abrasive Machining'.

Lapped components are widely used by aircraft and motor manufacturers, electronics companies, clockmakers and toolmakers, as well as in the optical and radar gas industries. Machine lapping is used, for example in manufacturing:

  • Pneumatic valves
  • Steel moulds
  • Meter equipment
  • Precision gyroscopes
  • Engine components
  • Printing machinery
  • Inspection & test equipment
  • Hydraulic valves
  • Slip gauges
  • Pumps
  • Seals
  • Gearboxes
  • Compressors
  • And more...
