Transcript of Highly sophisticated carbide for drilling and milling in the automotive industry and cutting...
Highly sophisticated carbide for drilling and milling in the automotive industry and cutting applications for difficult-
to-cut materials.
President: Dr. Ing. Konrad Friedrichs
high performance carbide of outstanding quality
long tradition of high quality
heavy expenditures in R&D
development of modern manufacturing procedures
rods in diameter ranges from Ø 1 mm to Ø 16 mm and flat bars in various carbide grades
extended shop floor for additional state-of-the-art sintering furnaces
modern kneading machines and extruders
innovative work places for quality control department
KFMG20
88,5 % coarse tungsten carbide and 11,5 % of cobalt
high toughness and impact strength
1.5 mm x 2.2 mm – 16,6 mm x 3,5 mm / variable length
to chip cross-sections, interrupted cutting, and varying cutting depths, cast iron, annealed cast iron, steel, paper knifes and wood
flat bars
94 % ultrafine tungsten carbide and 6 % of cobalt
drilling PCB-applications in bigger dimensions of 0.25 mm – 0.5 mm
ø1.2 – ø1.5 mm / variable length up to 400 mm
KFM606 high hardness, crack
and chip resistance, process stability caused by constant wear of cutting edges
92 % superfine tungsten carbide and 8 % of cobalt
high wear resistance combined with high service life of very sharp cutting edges
