  - Surface finish processes are used to obtain good surface finish and dimensional accuracy of the components. Finishing of rolling contact bearings, journals of sliding contact bearings are done by using these surface finishing processes.
  
  The different types of surface finishing process are:
  
  1) Grinding: It is a abrasive machining process which uses grinding wheel as cutting tool.
  
  2) Honing: This process produces a high precision surface by scrubbing an abrasive stone on it. It is used to improve geometric form and surface texture of a surface.
  
  3) Lapping: In this process, two surfaces are rubbed together with an abrasive between them.
  
  4) Buffing and polishing: Work wheel or leather strop is used to obtain smooth surface finish by using an abrasive.
  
  - Turning is a metal cutting process in which the material is removed from outer diameter of the workpiece.
