Small optical freeform, PRISMATIC AND ASPHERIC grinding components. The Cranfield Precision TTG is the ultimate ultra-precision aspheric and freeform optics grinding solution. Engineered specifically for high-end optics and molds including medical and aerospace components, up to 350mm in diameter. Cranfield Precision TTG.

Provides smooth, square, parallel and accurate workpiece surfaces. When ultrasmooth surfaces and finishes on the order of microns are required, lapping and honing machines (precision grinders that run abrasives with extremely fine, uniform grits) are used. In its "finishing" role, the grinder is perhaps the most widely used machine tool.

Grinding Machine Definition. A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the material.It is a process of metal cutting by using a rotating abrasive wheel from the surface of the workpiece. Generally, the grinding is a type of finishing operation to make sure that there is high …
