Lapping Machines

Lapping is a cost effective process for rapidly achieving flatness, parallelism and surface finishing to a wide range of components & materials, the process is used across a diverse industry spectrum.

We design and manufacture lapping and polishing machines for industry suppliers, worldwide. Ranging from 380mm to 2,500mm diameter they are supplied in three standard formats and specialised to single sided lapping.

We are able to adapt our machines to offer a bespoke solution to any handling or tool requirements.

  • Where parts are heavy enough to lap under their own weight or under the hand weights supplied, an open face machine is sufficient.
  • When extra pressure is required to reduce cycle times, we provide machines with a pneumatic pressure pad over each ring.
  • The third option is a water cooled sub plate. Where factors such as abrasive use, parts being lapped and pressure combine to heat the plate and cause it to deform, water cooling can prevent the build-up of heat and help maintain good flatness.

Other special features that can be offered: variable speed drive; soft start; pneumatically controlled table tops and special jigging.

Our machines can also be adapted to suit a wide range of abrasives from diamond to peristaltic pump systems.
