Machine overview:
The LP50 is a one to three workstation machine which permits both lapping and polishing (although not at the same time). The lapping process uses an automatic flatness control system. The flatness of the polishing plate is checked before every run with a single dial gauge and a master flat block. A flow of abrasive fluid is supplied to the lapping / polishing plate during the run. The machine is controlled from a membrane control panel at the front including a process data screen.
