ABSTRACT:
For machining operations employing cutter heads, use is made of wear-resistant cutting materials, and the cutter heads are operated at constantly increasing cutting speeds and, for coarse machining operations, with high cutting forces. This requires on the one hand a highly reliable mounting of the individual cutter blades or cutter blade carriers, respectively, and on the other hand the possibility of axially and radially adjusting the cutter elements in the micrometer range for the compensation of wear.
The invention provides a cutter head provided with cutter blade carriers (8) having an axial guide stem (9) and a cutter blade mounting portion (10), the guide stem (9) being received in an eccentric bushing (17) acting as a radial adjustment bushing, and coupled therewith for axial adjustment. The eccentric bushing (17) is retained in the main body (2) of the cutter head (1) at an axially fixed position for rotation in the circumferential direction. The cutter blade carrier (8) is locked in the cutter head (1) by means of a radial clamping device.
