Abstract
A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the face cutter head includes a positive blade seating and stick-type rectangular or square cross-section cutting blades (6) are clamped tight to the positive seating surfaces (14, 18). The cutting blades are adjustable radially by axial movement by a non-self-locking system.
Claims17
A cutter head for a gear cutting tool, said cutter head comprising:
- an axis of rotation,
- a first side and a second side spaced axially from one another,
- at least one cutting blade mounting and positioning slot arranged in said cutter head and having a length extending from said first side to said second side, said at least one slot comprising a radial seating surface and a tangential seating surface arranged perpendicular to one another,
- a clamping mechanism located in said at least one slot, said clamping mechanism being capable of delivering a clamping force to a corner region of a cutting blade, having a square or rectangular cross-section, mounted in said at least one slot, said corner region being remote from said radial seating surface and said tangential seating surface of said at least one slot,
- whereby a first portion of the clamping force is directed to and effects a clamping of the cutting blade against said radial seating surface and a second portion of the clamping force is directed to and effects a clamping of the cutting blade against said tangential seating surface.

The cutter head of claim 2 further comprising an angular clamping block having a shape complementary to said corner region of the cutting blade.
A gear cutting tool comprising:
- a cutter head having an axis of rotation, a first side and a second side spaced axially from one another, at least one cutting blade mounting and positioning slot arranged in said cutter head and having a length extending from said first side to said second side, said at least one slot comprising a radial seating surface and a tangential seating surface arranged perpendicular to one another,
- an angular clamp block located in said at least one slot,
- a cutting blade having a square or rectangular cross-section positioned in said at least one slot, said clamp block contacting a corner region of said cutting blade, said corner region being remote from said radial seating surface and said tangential seating surface of said at least one slot,
- at least one clamp screw positioned in said cutter head at each of said at least one slot, said at least one clamp screw exerting a clamping force against said clamp block and said cutting blade,
- whereby a first portion of the clamping force is directed to and effects a clamping of the cutting blade against said radial seating surface and a second portion of the clamping force is directed to and effects a clamping of the cutting blade against said tangential seating surface.
