What is honing and lapping process?

What is honing and lapping process?

What are lapping and honing? Lapping is a sanding or polishing method used to create an accurate finish on a flat or domed surface of a part. Honing is a method of internal grinding used to achieve a precise surface finish and shape on the inside diameter (ID) of a tube, bore, or hole.

What is the purpose of lapping tool?

Laps and lapping tools are used for precision surface finishing, often in conjunction with loose abrasive compounds. Lap is a soft material that is charged with an abrasive and is used for cutting harder material. A lapping machine uses a charged lead piece as lap for cutting a hardened steel piece.

What is lapping polishing?

Lapping and polishing is a process by which material is precisely removed from a workpiece (or specimen) to produce a desired dimension, surface finish, or shape.

What is a lapping process?

Define Lapping: The term “lapping” is used to describe a number of various surface finishing operations where loose abrasive powders are used as the grinding agent at normally low speeds. It is a process reserved for products that demand very tight tolerances of flatness, parallelism, thickness or finish.

What are the advantages of lapping?

Advantages of lapping: Extreme accuracy of dimensions. Correction of minor imperfections of shape. Refinement of surface finish. Producing close fit between mating surfaces.

What abrasives are used in lapping?

There are four basic types of abrasives that are used in lapping and polishing processes: silicon carbide (SiC), aluminum oxide or alumina (Al2O3), boron carbide (B4C), and diamond (C). All of these abrasives have distinct properties and are used for different materials and applications.

What is the principle of lapping?

Principle of the Lapping Process: Abrasive particles are poured over the lapping plate and the workpiece is rubbed on it. The Abrasive particles remove microscopic material from the workpiece when a force is applied during the relative motion between the plate and the workpiece.

Which material is used for lapping work?

The abrasive materials mainly used in lapping processing are silicon carbide (SiC), corundum (Al2O3), boron carbide (B4C) and, increasingly, diamond. The lapping disc produces a rotary movement and serves as a carrier for the lapping slurry, workpieces and dressing rings.
