| 摘要 |
The invention relates to a machine tool with a tool shank and a cutting head made from different materials, which are joined to each other on opposite joint surfaces in a positive material fit by means of a joint layer made of a ductile solder material. According to the invention, in order to obtain a solder connection which is substantially stress-free, powder particles made of a temperature-resistant material with a thermal expansion coefficient which is lower than the solder material are embedded-into the joint layer and the density of the powder particles varies along the entire thickness of the joint layer. |
