Lapping is an abrading process used to remove minute amounts of metal from a surface that must be flat accurate to sizee and smooth. lapping may be performed for any of following reasons:
1. To increase the wear life of a part
2. To improve accuracy and surface finish
3. To improve surface flatness
4. To provide better seals and eliminate theneed for gaskets
Lapping maybe performed by hand or machine, depending on nature of the job. Lapping is intended to remove only about 0,0005 in or 0,01 mm of material.
Types of laps
Laps may be used to finis flat surfaces holes or the out side of cylinder in each case the lap material must be softer than workpiece.
