Precision Grinding Services

Precision grinding services perform operations such as centerless grinding, creep feed grinding, double-disc grinding, internal grinding, external grinding, jig grinding, surface grinding, and thread grinding. Centerless grinding is a machining operation in which an abrasive wheel grinds metal from a bar’s surface while a regulating wheel forces the bar against the grinding wheel. Creep feed grinding is a type of plunge grinding that uses specialized grinding equipment. The grinding wheel is fed into the work at very slow infeed rates. Disc grinding and double disc-grinding use a large wheel to produce flat, parallel parts for high-volume production. Internal grinding or ID grinding is used to grind the inner diameter (ID) of holes. By contrast, external grinding or OD grinding is used to grind the outer diameter (OD) of cylindrical parts. Jig grinding uses very precise machines for locating and generating very accurate holes, contours, and surfaces to tolerances of .0001" or less. Surface grinding mounts the workpiece a table for back and forth feeding under the grinding wheel. Thread grinding is used to produce lead screws, ball screws, and worms. Precision grinding services that perform other types of grinding operations are also available.
