Question

3. What is known as burishing​

Answer 1

Answer:

Burnishing is the plastic deformation of a surface due to sliding contact with another object. It smooths the surface and makes it shinier. Burnishing may occur on any sliding surface if the contact stress locally exceeds the yield strength of the material.

Answer 2

Explanation:

=>Burnishing is the process of rubbing metal with a small hard tool, which can be either a ball type or roller type, to compact the surface.

It is a very useful finishing technique which can increase the work piece surface finish as well as adding micro hardness. Burnishing is also known by various other names such as:-

1. Super finishing process
2. Ballizing process
