Title:
MILLING HEAD FOR MILLING CHAMFERS
Document Type and Number:
WIPO Patent Application WO2005095038
Kind Code:
A3
Abstract:
The invention relates to a milling head for milling chamfers, especially for a mobile chamfer miller, comprising successive seats for blanking dies, said seats having a position in which the blanking dies with a leading edge angle of between 40 and 75 DEG operate respectively on average with a positive effective cutting angle of at least 6 DEG and a clearance angle of at least 6 DEG , and are provided for a border comprising blanking dies with a staggered arrangement of the cutting edges, such that respectively only one cutting edge length of 15 mm, preferably 12 mm, at the most, is active. Said measures increase the cutting performance of the milling head. The reduced cutting edge length can be formed on a long blanking die instead of using a shorter blanking die, in such a way that the cutting edge is interrupted by cavities or other e.g. flat triangular recesses on the surface of the blanking die. The staggered arrangement is then comparatively small.
