Lapping and Polishing Basics - South Bay Tech

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

The Performance of Polycrystalline Diamond (PCD) Tools ...

Tool material loss in the wear process was caused by the development of thermal cracks. The development of PCD tools' wear made of small-sized diamond grains was a steady adhesion-abrasion process without any catastrophic damage. In contrast, a large-scale fracture happened in the wear process of PCD tools made of large-sized diamond grains.

ABRASIVE TECHNICAL INFORMATION - MC Finishing

synthetically in a high pressure and high temperature process. Most diamonds that are mined are used industrially and most diamonds used in industry are synthetic. Diamond abrasives are used because of their hardness which is a 10 on the Mohs scale and because of their thermal conductivity. Diamonds have a face cubic structure.

An Introduction to the Optics Manufacturing Process

adhered to a polishing tool which is the inverse of the radius of optic being polishing. The tool with the pitch will be placed on the optic and rubbed together, much like the grinding process. As the polishing process continues, the pitch will slowly conform to the shape of the optic so that the surface of the optic is smoothed out, but its ...
