Speedfam single side lapping/polishing are versatile 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 plates 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 which are continuously fed on
The machine plate get charged in the plate and cuts the
Material from the surface of the work piece transferring the
Plates flatness on to the work piece surface.
The surface finish produced on the work piece depends upon abrasive particle size used in the process.
Applications
-metals:valve bodies,automobiles parts, valve wedges ,seat rings ,tools & die parts, mechanical seals,sewing machine parts.
-ceramic:water pump seals,chemicals seals,facets
-watch parts: watch dials, movements & hands,sapphire glass.
-electrical & electronics :ferite cores,`e`, `u` cores, switchgears contacts, rectifiers & diodes
-carbon:carbon seals,submersible pump bearings
