MaxiMill HEC
CERATIZIT’s MaxiMill HEC offers
performance advantages
CERATIZIT’s MaxiMill HEC cutters will help users maximize their productivity when machining Cast Iron components.
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,
imp:act 01/08
cylinder heads, turbochargers and pump cases,
etc. “MaxiMill HEC is the result of an ongoing and
extensive development program 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 maximize 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 around 660 ft/
min, 0.009"/tooth feed rate with up to 0.19" depth of cut
and 3.11" width of cut. Similarly, GGG 70 material at a
hardness of HB 240-300 can be cut at 590 ft./min at a feed
of 0.0078"/tooth.
