Lapmaster produces a wide range of air bearing spindle and conventional belt -drive optical polishing machine for use in both plano optics production and R&D environments.

The air bearing line of optical polishers, available with 36" and 48" diameter pitch laps, are designed so that the pich lap and support plate ride on a very thin cushion of compressed air. These machines are driven from an electric motor via a lay shaft, and power is transferred to the lap using a multi-vee drive belt around the circumference of the support plate. This unique design virtually elimminates vibration at the polishing surface and dramatically improves component flatness and finish results.

The conventional belt-driven line of ptich polishers, available with 60",70",84" and 120" diameter pitch laps, are built on a cruciform-shaped structual steel base. The mechanical reduction gearbox and motor are mounted to the side of the polishing plate. The polishing plate is supported by a graphite support plate turning on a heavy duty bearing. Power is transmitted via a flat belt, and the moving parts of the system are enclosed within a panel-clad base.This innovatie polishing plte support design prevents plate deflection common on very large continuous polishers. Isolation of the motor and geabox also help to virtually eliminate vibration at polishing surface.
