The SS-56H lapping machine is equipped with a 56-inch (1422 mm) diameter lapping plate made of HT300 gray cast iron, compliant with ISO 185 (2005) standards. The lapping plate consists of multiple segments secured to a support plate with screws.
The pressure weight is connected to the pneumatic cylinder's piston rod via a self-aligning bearing. The cylinder is mounted on a crossbeam supported by two vertical columns above the lapping plate.
The primary function of the pneumatic system is to eliminate the need for manual handling of the pressure weight during loading and unloading. Additionally, extra pressure can be applied to the workpieces upon customer request.
The machine is configured as standard for use with loose abrasives; configurations for water and diamond slurry are also available as options upon request.
Operator safety is a primary focus of the equipment's design. A two-hand safety relay controls the vertical movement of the pressure weight; since simultaneous two-hand operation is required to initiate the process, this ensures the operator's arms are not injured while the weight is descending.
Another safety feature allows the pressure weight to be locked in any position, preventing it from falling in the event of a sudden loss of air or power supply.
The flatness of the lapping plate and the workpiece can be adjusted by modifying the position of the conditioning ring on the lapping plate.
The lapping plate drive system utilizes an independent motor, a worm gear reducer, and a belt drive.
