Flat Lapping

Lapping is a cost effective method of machining where components are required to be flat, parallel, need controlling for size or require a fine, or specific surface finish.

Lapping can be applied to a wide range of materials and components and the lapping process is used in a diverse range of industries.

Lapping is ideal for close tolerance work.  Opus can work to a flatness and parallelism tolerance of 0.05 micron and thickness to ± 0.05 micron (size and material dependant).  We can achieve a variety of surface finishes, reflective or matt down to 0.007 micron Ra.

Opus has worked with & helped many well know companies in the oil & gas, motor sports, aerospace, defence industries along with national metrology laboratories and institutes worldwide.


Most materials can be lapped, Opus has particular experience with all types of steels including stainless, tungsten carbide, various ceramics including PZT material.

Opus is one of the few companies where all the work can be verified in our temperature controlled laboratory which also holds UKAS accreditation for calibration work

Our flat lapping department is equally at home with a one off component or working with batches of 10,000+

Our extensive range of plant and equipment includes surface grinders, single and double sided lapping machines laser flatness interferometers, ultrasonic cleaning facilities,  Talysurf 10 and a  laser marking machine.
