A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation. Thus, grinding is a diverse field.
Lenses were produced by grinding them against a metal tool called a " lap," which had been produced using a lathe. Convex lenses required a lap having a portion of a hemispherical cavity. A male form was used for concave lenses. The laps could be made from any metal, since hardness was not a major factor.
