Tough materials continue to drive creep-feed grinding

Horsepower well beyond that of a standard grinding machine is required for creep-feed grinding to gener­ate and maintain the high-productivity forces needed to remove large amounts of material quickly. While a typical reciprocating grinder generates 20 hp to 50 hp, a common creep-feed grinding machine ranges from 60 hp to 150 hp and more.

Centerless grinding - Wikipedia

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ...
