Carbide specialist Ceratizit has published a four-page report, written by Dr Uwe Schleinkofer, head of R&D at the company.

Dr Schleinkofer reports on cutting process requiring an improved interaction of tool parameters such as coating and cutting edge geometry. This complex task can be solved with a mixture of know-how and competence in the field of testing.

Demands are rising in terms of both machining quality and machining efficiency due to rapid innovations in production machining of components and the fast-paced development of work piece materials. However, it has to be accepted that the cutting process depends on so many factors that it is virtually impossible to put a theoretically optimal process into practice.

The main factors influencing the process are defined by the highly complex interaction of powder, substrate, tool coating, cutting edge geometry, chip groove, tool design and the related process parameters in technical application. In the years from 1998 to 2002 Ceratizit created the water-spray process for the manufacture of carbide granulate, which was patented and brought to production stage on a large scale. This powder production represented a quantum leap in the manufacturing of carbide granulates for the entire sector, the company says.
