| 摘要 |
The invention relates to a tool, which is intended for chip removing machining and comprises a basic body and a replaceable cutting insert (2), which is indexable by means of a cutting edge exchange mechanism, in which there is included a long narrow ejector (32), which in a front part has an attachment (34) for the cutting insert and interacts with means for transforming a rectilinear, axial projection of the ejector into a simultaneous turning of the same. The cutting edge exchange mechanism includes, on one hand, a stop collar (15), which is fixedly anchored in relation to the basic body and through which the ejector (32) is movable back and forth, and, on the other hand, a carrier (23) included in a rear part of the ejector. In addition, between the carrier (23) and the stop collar (15), there is arranged a mechanical compression spring (14), which always aims at spacing apart the carrier (23) from the stop collar (15). In addition, the invention also concerns an autonomous cutting edge exchange mechanism as such. |
