Development of Sphere Lapping Attachment for CNC Lathe

Lapping is one of the techniques where form and surface roughness are controlled on surface like flat, cylindrical and spherical shape. Now a days with optimized parameters and the process is being applied to any material and shape which are not subject to plastic deformation due to their own weight or to mechanical load by machining. It is used less for finish and more for form accuracy, such as flatness in the case of flat objects or sphericity in the case of spheres. The parameters optimization is key factor for lapping spherical surface. This paper gives brief about development of Sphere Lapping Attachment for CNC Lathe with Spherical tolerance accuracy within 1 micron for lapping spherical surface with scratch-free, mirror finish high-quality surface. This Attachment is effective on stainless steel and Cobalt Chrome (Co Cr) alloyed metals.
