Abstract:

Burnishing is process in which irregularities on machined surface deformed plastically using hard ball or roller. The deforming action of the ball of roller fills peaks into valleys due to which properties at surface improves along with surface finish. In present work ball and roller burnishing process is carried out on cylindrical components of free cutting brass in presence of abrasive particles of 20/40 micro coarser size in the form of paste (paste) and its effect studied on surface roughness and micro hardness. Two parameters namely burnishing force and speed were controlled during burnishing process. It was found that the application of paste in between specimen and tool interface is advantageous in case of ball burnishing where as in case of roller burnishing the results were adversely affected by paste.
