Frasal Tool Co., Inc is proud to offer precision CNC turning and hard turning services. Hard turning is typically defined as the turning of a part or barstock harder than 45HRC on a lathe or turning center. Since improved surface finish can now be achieved, hard turning is often considered a replacement for grinding operations or as a pre-grinding process. Hard turning is most often performed on post-heat treated parts with surface hardness ranging from 45HRC to 68HRC or even higher. The process of hard turning shares many fundamentals to soft turning. This gives hard turning an inherent advantage over grinding, which requires specific knowledge and experience that not all machinists have. Our hard turning services are often a great compliment to the CNC grinding capabilities we possess in manufacturing.
