24 Lapper

Lapping machines are precision surfacing tools used to produce flat, smooth surfaces on workpieces through controlled abrasive wear. Single-sided lapping machines process one side of a workpiece at a time, using a rotating lap plate and an abrasive slurry.

The Lapmaster 24 has a heavy-duty floor-standing base with an integrally mounted drive motor and reduction gearbox. The abrasive system includes a storage tank, pump, and multiple-point distribution for the slurry. The lap plate rotates at 70 rpm. The machine uses high-density cast iron serrated conditioning rings with adjustable roller bearing yoke assemblies to maintain lap plate flatness during operation. In the pneumatic lift version, the machine provides controls for raising and lowering the pressure plate using a two-hand anti-tie-down system, and the load can be varied between 15 kg (33 lbs) and 85 kg (187 lbs). Pressure weights are supplied with the open face version to apply load to the workpieces.^[5][6]

Lapping machines are used in manufacturing processes where high flatness and surface finish are required, often as a step before polishing or after coarse grinding. In semiconductor and optics fabrication, lapping is applied to substrates and components to achieve precise dimensional tolerances and surface quality.

The Lapmaster 24 can be used to process a wide variety of materials including semiconductors, electro-optics, ceramics, metals, and other specialty products. The machine is capable of both lapping and polishing when equipped with appropriate optional tooling such as solid stainless steel backing plates, composite faced plates, or polishing pads.^[5][6]
