Gear cutter with radial adjustability of square or rectangular stick blades

A bevel gear face cutter head for face hobbing and face milling of bevel and hypoid gears, said cutter head being generally disc-shaped and rotatable about a cutter head axis, said cutter head comprising:

• a top surface and a bottom surface,
• one or more cutting blade positioning slots arranged in said cutter head with each of said blade positioning slots extending between said top and bottom surfaces and with each of said blade positioning slots defining a four-sided shaped cross-section,
• said cutting blade positioning slots each having at least one blade seating surface extending between said top and bottom surfaces,
• said at least one blade seating surface having a modified shape and extending from said top surface to said bottom surface wherein said modified shape departs from the straight line shape of a continuous straight seating surface extending from said top surface to said bottom surface,
• wherein the cutter head is capable of clamping a cutting blade having a four-sided shaped cross-section to the at least one blade seating surface such that the blade is pre-clamped and axially located and is capable of thereafter having the radial location of the blade tip adjusted by an increase of the torque of a clamp screw located in the area of the modified portion of the blade seating surface.
