8" Tin Faceting Lap

Tin Polishing Lap

The Tin lapping Polishin Lap is a specialized tool used in the manufacturing and finishing processes of various materials, particularly in the field of optics and precision machining. It is a flat, circular plate made of tin or another soft and malleable material, such as copper or cast iron, with a highly polished surface.

The primary purpose of a Tin lapping Polishin Lap is to provide a smooth and flat surface for lapping and polishing operations. lapping is a precision machining process used to achieve extremely tight tolerances and fine surface finishes on materials like glass, ceramics, metals, and semiconductors. During lapping, abrasive materials, such as diamond paste or abrasive slurry, are applied to the lapping plate's surface, and the workpiece is rubbed against it in a controlled manner. This abrasive action helps remove imperfections and irregularities from the workpiece's surface, resulting in a high degree of flatness and smoothness.

Tin lapping Polishin Lap are valued for their ability to provide a uniform and consistent surface for lapping, which is essential in applications like lens manufacturing, semiconductor wafer processing, and precision optics. The use of tin or other soft materials allows the lapping plate to conform to the shape of the workpiece, ensuring even material removal and preventing damage to delicate or brittle materials.

The Tin lapping Polishin Lap is a classic part of the faceting kit. They work great for carrying both diamond and oxide polishes, and have ideal hardness and friction characteristics for working a very wide range of gem materials from hardness 4 or less to 9.
