Lapping and polishing machines - single side

Lapping and polishing machines from Thane-based SpeedFam-IPEC (India) Pvt Ltd are precision machines designed to produce lap/polish flat surfaces within a flatness of 1 light band (0.3 micron) or less, and surface finish of 0.02 Ra with absolute uniformity on almost all types of hard materials. Working principle * Lap/polish plate revolves at slow speed * The conditioning rings held in position on the machine plate also rotate freely * The work pieces are kept freely inside conditioning rings with the surface to be lapped facing the machine plate * The sharp abrasive particles that are continuously fed on the machine plate get charged in the plate and cut the material from the surface of the work piece transferring the plate flatness onto the work piece surface * The surface finish produced on the work piece depends upon abrasive particle size used in the process. Advantages: * No clamping or distortion - most of the components are held in "free" condition * No fixturing required as reference is established from surface being lapped * Non-magnetic - non-metallic or dissimilar materials can be processed with ease * Thin parts up to 0.5 mm can be lapped easily * Close tolerances on thickness control and part-to-part thickness can be achieved * Brittle parts can be processed without chippage or breakage
