Abstract
A milling cutter head intended for metal machining, particularly aluminum, comprises grooves in which are mounted cutting insert-carrying cartridges and spacer plates. The sides of the cartridge and the spacer plate that are in contact are serrated in the same direction. The other side of the spacer plate and the side surface of the groove being in contact with it are serrated in a direction which is substantially perpendicular to the first mentioned serration. In this way, it is possible to independently and precisely adjust each of the axial and radial directions of the cutting edge.

A milling cutter head comprising, a rotary body defining an axis of rotation, cutting inserts carried by cartridges having insert receiving seats, said cartridges placed in grooves spaced around an outer periphery of the body;
- a spacer plate being placed in each groove one side of each groove being serrated and in contact with a first correspondingly serrated side of the spacer plate;
- one side of the cartridge being serrated and in contact with a second correspondingly serrated side of the spacer plate, the second side being on an opposite side of the spacer plate from the first serrated side of the spacer plate in a circumferential direction;
- the serrations on the two sides of the spacer plate disposed in respective directions arranged substantially perpendicular to each other, a first of the directions being substantially parallel to the axis, and a second of the directions being substantially radial with respect to the axis;
- a first manual actuator engaged directly between the cartridge and the body for displacing the cartridge in the first direction;
- a second manual actuator engaged directly between the cartridge and the body for displacing the cartridge in the second direction;
- the first and second actuators being arranged so that the cartridge is displaceable in the first direction without being displaced in the second direction in response to actuation of the first actuator, and is displaceable in the second direction without being displaced in the first direction in response to actuation of the second actuator.
