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).
Claims11
A blade holder for fastening to a face mill, comprising a shank-like pin and a head with a blade having a secondary cutting edge formed by an intersection between a rake face and a flank, wherein the secondary cutting edge includes a rounded bevel having a first radius at a first end of the secondary cutting edge and a second, different radius at a second, opposite end of the secondary cutting edge, the first radius being smaller than the second radius.
A blade for a face mill comprising a secondary cutting edge formed by an intersection between a rake face and a flank, wherein the secondary cutting edge includes a rounded bevel having a continuously varying radius from a first end of the secondary cutting edge to a second, opposite end of the secondary cutting edge, the radius at the first end being smaller or equal to the radius at the second 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 blade having a rake face, a flank and a secondary cutting edge formed at an intersection between the rake face and the flank, the secondary cutting edge having a rounded bevel, wherein the bevel extends along the secondary cutting edge and has a width that decreases to 0 mm at a first end of the secondary cutting edge, and reaches a maximum at an opposite, second end of the secondary cutting edge when viewed perpendicularly to a rotation axis of the face mill.
