Lapping with EFCO lapping machines

EFCO lapping machines are designed for the precision machining of safety valves, ball valves, compressor valve disks etc. We are manufacturers of portable and stationary lapping machines.

Lapping is one of the fine or ultra-fine machining processes with which high surface qualities, extreme shape accuracy and tight dimensional tolerances can be achieved.

Lapping is defined according to DIN 8589 and means machining with loose grain distributed in a liquid or paste. This lapping mixture is located between the workpiece and a lapping wheel. As lapping does not usually involve heating the lapping piece, deformation is ruled out. Many of the EFCO sanding machines can be used with lapping accessories for the precise finishing of surfaces. They are complemented by a range of special machines for lapping.

Where are our lapping machines used?

Our lapping machines are used for processing fittings in various sectors and branches of industry. We have compiled a small selection here.
  • Valve service
  • Chemical industry
  • Power generation
  • Gas production
  • Petrochemistry
  • Refineries
Lapping has become established as a machining process in valve processing, particularly where leak-free shut-off devices are used (e.g. for safety valves, mechanical seals for boiler water feed pumps, compressor valve disks, etc.).

Where to rent a lapping machine?

Professional lapping machines can rarely be ordered from a catalog. Adjustments and additional accessories are often required for lapping machines.

With our RentalService you can rent an EFCO lapping machine. Our lapping machine rental service allows you to use the latest lapping technology and experience the benefits of our machines for yourself.

We rent out EFCO grinding technology, EFCO turning technology and EFCO testing technology.
