Generally speaking, hard turning is an alternative to grinding. As such, it''s a finishing process with emphasis on dimensional accuracy and surface finish quality. Like some grinding operations, hard turning is used to finish a workpiece that has been heat treated.
Hard turning is a type of turning done on materials with a Rockwell C hardness greater than 45. It is typically performed after the workpiece is heat treated. The process is intended to replace or limit traditional grinding operations. Hard turning, when applied for purely stock removal purposes, competes favorably with rough grinding.
