Abstract
The invention pertains to a cutting tool for material-removing machining of materials, comprising a shaft (12) with a tool head (16) having a cutting blade (70). For the effective cooling of the tool blades, the shaft (12) has a single coolant supply channel (26) running in the longitudinal direction of the shaft and a single coolant return channel (28) running in the longitudinal direction and the tool head (16) has a single flow channel (78) connecting the coolant supply channel (26) to the coolant return channel (28) which is thermally coupled to the tool blades (70).
Claims21
Cutting tool (10, 110, 166) for material-removing machining of materials, comprising a shaft (12, 114, 170) with tool head (16;
- 120;
- 172) having a tool blade (70, 72;
- 148, 150;
- 208, 210),
- characterized in that
- the shaft (12;
- 114;
- 170) has a single coolant supply channel (26;
- 122;
- 178) running in the longitudinal direction of the shaft and a single coolant return channel (28;
- 124, 180) running in the longitudinal direction and the tool head (16;
- 120;
- 172) has a single flow channel (78;
- 164;
- 200) connecting the coolant supply channel (26;
- 122;
- 178) to the coolant return channel (28;
- 124, 180) which is thermally coupled to the tool blades (70, 72;
- 148, 150;
- 208, 210).
Cutting tool (216, 332), such as a drilling tool or milling tool for the material-removing machining of materials with a tool carrier (218;
- 334) having a plurality of tool blades (222, 224, 226;
- 372), such as a hollow drill (218) or face milling cutter (334), especially a face milling cutter, wherein the tool blades are supplied with coolant via coolant supply channels (242, 246, 250;
- 282) and via coolant return channels (244, 248, 252;
- 388), which are fashioned in the tool carrier (218;
- 334) and are fluidically coupled via a coolant distribution system (264;
- 375) to a single coolant supply channel (260;
- 406) and a single coolant return channel (262;
- 404), which run in an adapter (256;
- 336) connected to the tool carrier (218;
- 324) and are coupled to a coolant reservoir, characterized in that
- the coolant distribution system (264;
- 375) has an annular coolant supply distribution channel (268;
- 386), which is coupled at its inlet to the single coolant supply channel (260;
- 406) and at its outlet to the plurality of coolant supply channels (242, 246, 250;
- 382), and the coolant distribution system has a coolant return distribution channel (286), which is coupled at its inlet with the plurality of coolant return channels (244, 248, 252;
- 388) and at its outlet with the single coolant return channel (262;
- 406).
