27/11/2007 CERATIZIT’s MaxiMill HEC offers performance advantages

The launch of CERATIZIT’s MaxiMill HEC face milling system at EMO 2007 is further proof of the high levels of research and development taking place at its Reutte, Austria manufacturing facility.

The MaxiMill HEC accepts CERATIZIT precision-manufactured inserts of either carbide, ceramic or CBN material, which provide up to eight useable edges. These tangentially-mounted inserts are mounted in such a way as to ensure maximum cutting performance and cutter stability, while at the same time reducing the power required to operate them at their optimum, making them suitable to a much wider range of machine tools.

The result is a face milling cutter that will generate high table feeds, long and consistent tool life, economic application and process security. While MaxiMill HEC can be used in virtually any C.I. face milling application it will be of real interest to those companies supplying the automotive sector where the volumes and component types will suit its particular characteristics and generate the maximum productivity and cost savings for the end-user. Typical application areas for MaxiMill HEC would be cast iron components such as contact faces of crank cases, cylinder heads, turbochargers and pump cases, etc.

“MaxiMill HEC is the result of an ongoing and extensive development programme at CERATIZIT”, says Conan Jackson, CERATIZIT UK’s Sales Manager. “HEC is a welcome extension to the existing MaxiMill range and will provide many of our automotive customers with the opportunity to maximise their machine capacity while reducing tooling costs.”

With the LNHX 1106PNER inserts available in grades CTC3215 (carbide), CTN3105 Si3N4 (ceramic) and segmented CBN, the cutting data achieved is impressive. For example, machining GG25 material at a hardness of HB 180-220 is achieved at 200m/min, 0.25 mm/tooth feed rate with up to 5 mm depth of cut and 79 mm width of cut. Similarly, GGG 70 material at a hardness of HB 240-300 can be cut at 180 m/min at a feed of 0.2 mm/tooth.
