| Lapping / polishing is a process
in which free abrasive particles are applied between the plate and
an appropriately - pressed flat part, cutting the part surface without
directional lines. Mirror polishing is expectable if abrasive particles
with reduced granularity are used in connection with the lapping plate
(a polishing pad). Lapping and polishing includes two-way, three-way
and four-way polishing, corresponding to the use of single-sided or
double-sided lapping / polishing machines. JENG YUEH 's lapping /polishing machine (single) controls the flatness of its plate subject to variations. Plate conditioning is enabled during the machining process, maintaining the plate with expected flatness in long life. |
