Rollomatic's notable and historic innovation of "pinch" grinding has been utilized in Rollomatic cylindrical grinding machines for several years. This process operates on the principle of peel grinding. A continuous engagement of a roughing wheel and a finishing wheel on either side of the blank ensures total support at any time during grinding. This guarantees the highest achievable concentricity in cylindrical grinding.

Rollomatic is holding European, US and international patents on the 'simultaneous engagement of a roughing and finishing wheel for cylindrical grinding?. Rollomatic has been successful by legal action in opposing efforts of other machine builders to copy this process.
