Hanover, 19 September 2011. LMT FETTE is setting new performance records by applying the latest BOEHLERIT coating to its face-milling cutters for machining cast materials.
TeraSpeed, an aluminium titanium nitride coating system, is created using chemical vapour deposition (CVd method). CVd provides extremely high adhesion and a uniform distribution of coating thickness on cutting and open areas. The coating itself is exceptional because of its hardness of roughly 3,500 HV. Additionally, an aluminium content of over 90% guarantees a high thermal resistance of up to 1,100 degrees Celsius – 200 degrees more than comparable coatings. This facilitates significantly higher cutting speeds: performance increases by 100% in face-milling applications and even by 200% in step-milling applications. Users therefore save considerable time and money.
