| 摘要 |
The invention relates to a rotatable tool for chip removing machining having a rotatable holder part (1) and a cutting part (2) that is rigidly and detachably connected to a front end of the holder part. In a front end portion of the holder part (1), a forwardly open slot (8) is formed, which separates two elastically flexible or resilient projections (9). For clamping of the cutting part (2) on the holder part (1), a male/female coupling is arranged, which comprises a central, male-like pin (10) on one of the parts and a corresponding seat (not visible) in the other part. Radially outside the male/female coupling, thrust load carrying support surfaces (16) are formed, which surfaces are at least partially conical in order to automatically provide an envelope surface on the pin and an interacting internal contact surface in the seat with a tendency of being pressed against each other during elastic deflection of the projections when the cutting part during operation of the tool is submitted to thrust forces which presses the conical support surfaces against each other. <IMAGE> |
