Cutting Tool Applications, Chapter 18: Lapping and Honing

Most lapping is done with a tooling plate or wheel (the lap) and fine-grained loose abrasive particles suspended in a viscous or liquid vehicle such as soluble oil, mineral oil or grease. Honing is a low-velocity abrading process. Material removal is accomplished at lower cutting speeds than in grinding.

The Differences Between Honing and Lapping - Indiana Precision Grinding

Lapping is generally used to remove "tenths", or ten-thousandths of an inch. Lapping uses "loose" abrasives on its plate instead of bonded abrasives that a honing wheel would. These abrasive particles are suspended in a viscous medium such as soluble or mineral oil. To achieve optimal performance, the abrasive must be uniformly graded.

What is the difference between valve lapping and valve grinding?

Valve lapping is a process of smoothing out the valve face and valve seat at the same time. The machinist applies a fine abrasive compound to the face of the valve and the seat and assembles the valve in the cylinder head. Then the machinist spins the valve while pulling it against the seat. The fine abrasive smooths both surfaces for a tight fit.
