Abstract
A tool head for use with a modular shank tool includes at least two preforms. Each preform of the at least two preforms is made separately from the other preform of the at least two preforms from granular materials and then put together and jointly compressed and integrally bonded.
Claims16
A method for manufacturing a tool head for use with a modular shank tool, wherein the tool head has a central longitudinal axis about which the tool head rotates during operation, the method comprising, prior to connecting the tool head to a tool shank of the shank tool:
- producing at least two preforms of the tool head separately from each other in an injection molding or diecasting process from granular materials;
- abutting the at least two preforms together in a desired relationship;
- and
- integrally bonding the at least two preforms together by jointly compressing the at least two preforms,
- wherein said producing step comprises forming at least one linear duct in one of the at least two preforms and at least one distributor chamber disposed in the other one of the at least two preforms,
- wherein the at least one distributor chamber is in fluid communication with the at least one linear duct in one of the at least two preforms, and
- wherein the at least one distributor chamber has a larger cross-sectional area than the at least one linear duct in one of the at least two preforms.
A method for manufacturing a tool head for use with a modular shank tool, wherein the tool head has a central longitudinal axis about which the tool head rotates during operation, the method comprising, prior to connecting the tool head to a tool shank of the shank tool:
- producing a first preform and a second preform of the tool head separately from each other in an injection molding or diecasting process from granular materials, wherein:
- the first preform comprises a cutter end structured to engage a workpiece;
- and
- the second preform comprises a coupling end structured to connect the tool head to a tool shank of the modular shank tool;
- abutting the first preform and the second preform together in a desired relationship;
- integrally bonding the first preform and the second together by jointly compressing the first preform and the second preform to form an integral bond along a connecting zone,
- wherein said producing step comprises forming a duct system for a cooling lubricant, the duct system comprising a straight duct portion disposed in the second preform and a distributor chamber disposed in the first preform, the straight duct portion leading into the distributor chamber, the distributor chamber having a larger cross-sectional area than the straight duct portion disposed in the second preform.
