Abstract
The invention relates to a cutter support (11) for fastening to a cutter head, comprising a shaft-like pin (11) and a head, having a soldered-in cutter (12) with a minor cutting edge formed by a face (27) and a free surface (28). According to the invention the minor cutting edge has a rounded area (25), the radius of which continuously increases from a minor cutting edge end (25a) at least to the cutting edge center, or to the other minor cutting edge end (25b).
Claims12
A blade holder for fastening to a face mill, consisting of a shank-like pin and a head with brazed-in blade having a secondary cutting edge formed by a rake face and a flank wherein the secondary cutting edge has rounding, the radius of which increases continuously from a secondary cutting edge end at least up to the cutting edge center or up to the other secondary cutting edge end.
A face mill for orthogonal rotary milling with eccentric tool orientation for the precision milling of bearings of a crankshaft or camshaft, the face mill having at least two eccentric blade holders each comprising a shank-like pin and a head provided with brazed-in blades each having a rake face and a flank having a bevel, the bevel extending along a secondary cutting edge and having a bevel width decreasing outward to 0 mm at ends of the secondary cutting edge and increasing inward up to a maximum value toward a center of the secondary cutting edge, a radius of a rounding of the bevel being at a minimum at the secondary cutting edge ends and at a maximum at the secondary cutting edge center.
