EFCO
lapping machines are designed for the
precision machining of safety valves, ball valves, compressor valve disks, etc. We produce
stationary lapping machines and
portable lapping machines from the manufacturer.
In addition, we provide a
small lapping machine or
mobile lapping machine via our
EFCO Rental Service.
Lapping is a fine or
ultra-fine machining process. Lapping machines are used to achieve high surface qualities, extreme shape accuracy and close dimensional tolerances.
Our
surface finishing machines enable
precision lapping in accordance with
DIN 8589. Both
surface lapping machines and
fine grinding are used to produce micro-fine
workpiece surfaces with exact
tolerance accuracy. DIN 8589 means machining with loose grain distributed in a liquid or paste. This
lapping mixture is placed between the workpiece and a
lapping wheel, resulting in the desired surface structure. As the lapping piece is generally not heated during
lapping and polishing,
deformation is ruled out.
In addition to our lapping machines, many of the
EFCO grinding machines with
lapping accessories can be used for precise finishing of
micro-fine surfaces. Our machines and
grinding techniques guarantee first-class results in
metalworking with machines. They are complemented by a range of special machines for lapping.
