Lapping can be applied to practically all metal/alloy combinations & non-metallic materials.

Lapping can be applied to practically all metal/alloy combinations and non-metallic materials including:
stainless & hardened steel silicon
titanium quartz
tin lead
magnesium zinc
silver gold
platinum ceramic
brass aluminium
nimonic hard plastic
glass tungsten
phenolic mozak

& many more.

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

Lapping today is a specialist machine process which has replaced the time and labour
intensive method of hand lapping.

Work piece capacity ranges from 3mm up to 1000mm in all shapes and sizes and weighing in excess of 50kgs.
The fastest and most accurate method of achieving flatness and parallelism with the ultimate degree of surface finish.
Rapid turnaround of work! No fixing or clamping required facilitating a rapid set up.
Stress free process without thermal distortion.
Process suitable for lapping most ferrous materials.
Soft materials can be lapped without the problems generaly associated with grinding.
Consistent size control over small or large batches.
Mixed batches of components can be processed simultaneously.
Typical flat tolerance 0.00025mm over a 150mm diameter.
Parallelism 0.0025
Surface Finish 0.025 Microns on hard materials
Size Control +/- .001mm
