Abstract
This disclosure relates to a cutting tool, having a main body, a cutting head, which is joined to the free end of the main body and is formed, by primary shaping, as a sintered piece provided with at least one cutting edge, and a cooling lubricant feed, which is led through the main body axially and which has a cooling lubricant distributor inserted into the cutting head for redirecting cooling lubricant into the region of the at least one cutting edge. According to this disclosure, a plurality of protruding spacers for keeping a gap clear with respect to the cooling lubricant distributor and/or the main body are sintered on a supporting surface of the cutting head as primary shaped elements.
Claims17
A cutting tool, comprising:
- a main body having a longitudinal central axis and configured to be clamped in a tool holder;
- a sintered cutting head joined to a free end of the main body, the cutting head having at least one cutting edge and a cooling lubricant feed which is led through the main body axially;
- a cooling lubricant distributor inserted into the cutting head and configured for redirecting cooling lubricant into a region of the at least one cutting edge;
- and
- a plurality of primary shaped protruding spacers sintered on the cutting head, wherein the cutting head forms an annular gap separating the spacers from the at least one cutting edge, the spacers configured to maintain a gap between the cutting head and the distributor for flow of the cooling lubricant.
A cutting tool, comprising:
- a main body having a longitudinal central axis and configured to be clamped in a tool holder;
- a sintered cutting head joined to a free end of the main body, the cutting head having at least one cutting edge and a cooling lubricant feed which is led through the main body axially;
- a cooling lubricant distributor inserted into the cutting head and configured for redirecting cooling lubricant into a region of the at least one cutting edge;
- and
- a plurality of primary shaped protruding spacers sintered on a supporting surface of the cutting head, the spacers configured to maintain a gap for flow of the cooling lubricant, which gap is between the supporting surface and the cooling lubricant distributor;
- and
- wherein the cooling lubricant distributor is screwed into a centering sleeve that is movable against an abutment of the cutting head.
