The innovative RPM-Synchronous Grinding process enables highly efficient manufacturing of various geometries in an ordinary plunge grinding process. An oscillation of the infeed axis, which is coupled to the rotary workpiece spindle axis, like in conventional non-circular grinding approaches is not required. This is achieved by using a fixed ratio of grinding wheel- and workpiece speed and also a non-circular grinding wheel geometry. In this first test series, practice-orientated circular steel-workpieces are Synchro-Finish ground with conventional vitrified grinding wheels for finishing applications. The surface topography of the Synchro-Finished parts is evaluated and compared with conventionally ground workpieces.
