in practice plunge grinding with a long sparkout time has proven itself as the standard manufacturing method. the surface quality given by the roughness values in the din standard is easy to achieve and to verify. the most important requirement for the shaft counterface is its leadfree condition however
plunge grinding is one of the most common production processes for precision shafts. a series of plunge ground shafts was obtained with designed lead angles from 0.5 rh to 0.5 lh in increments of 0.1° for testing. two additional shafts with 0.05 rh and lh leads were also obtained.
