EFCO
lapping machines are designed for the
precision machining of safety valves, ball valves, compressor valve disks etc. We are a
manufacturer and produce
stationary lapping machines and
transportable lapping machines.
We also rent out our mobile lapping machine via our
EFCO Rental Service.
Lapping is a fine or
ultra-fine machining process. Lapping machines achieve high surface qualities, extreme shape accuracy and close dimensional tolerances.
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. In addition to our lapping machines, many of the EFCO
sanding machines with lapping accessories can be used for precise surface finishing. They are complemented by a range of special machines for lapping.
