- Lapping is a precision finishing operation carried out using fine abrasive materials.
- This process:
- Improves geometric accuracy
- Refines surface finish
- Assists in achieving a high degree of dimensional accuracy
- Improves the quality of fit between the mating components
- While lapping, the lapping compound collects in the serrations and rolls in and out as the work is moved.
- Before commencing the lapping of the component, the cast iron plates should be charged with abrasive particles.
- Charging is a process by which the abrasive particles are embedded on to the surface of the laps which are comparatively softer than the components being lapped.
- Flat surfaces are hand lapped using a lapping plate having grooves to retain the lapping paste.
