Lapping is a loose abrasive machining process that differs from honing or grinding because the abrasive action comes not from a solid abrasive (like a grinding wheel) but from a slurry--abrasive particles mixed with oil or water.
Lapping tracks can be produced during both grinding and polishing. The causes are: incorrect disk/cloth surfaces for the actual operation or the wrong force. Also, combinations of these faults can cause lapping tracks.
This article is a guide for the use of lapping paste and grinding pastes. The correct lapping depends on the skill of the operator and generally circular or figure of eight method is used. Oil is used in the lapping paste as a base however the optimum quantity of oil should only be used and excess oil shoul be avoided as it is contrary to the cutting actions of the abrasives.
