SPP Series Lapping Machines

FEATURES:
SPP Series Pitch Polishers are capable of processing surfaces requiring absolute flatness and mirror-like finishes, such as optical flats, high-precision mirrors, optical glass, and the base reference surfaces of precision measuring instruments for metal products. They can achieve flatness up to 30 nanometers per square meter.

The Polishing Table utilizes granite to minimize thermal deformation caused by grinding, thereby preventing displacement of the table’s flatness. Additionally, since the grinding slurry is supplied from both sides of the workpiece and from the center of the grinding pad, stable slurry supply is ensured across the entire surface of the workpiece.

SPP series are custom made to meet customer specifications.
