Thermal clamping and release of tools involves heating chuck in one workstation of shrinkage device, inserting/removing tool, cooling, heating chuck in separates second workstation

摘要

The method involves heating the tool holding section of a first chuck in a first workstation (5-7) of a shrinkage device, inserting the tool shaft into the tool holder opening and/or removing a tool from it, actively cooling the tool holder section and heating the tool holder section of a second chuck in a second workstation of the shrinkage device separate from the first workstation. The method involves using a shrinkage chuck with a thermally expanding tool opening and a clamp section for clamping the chuck to the machine spindle. It involves heating the tool holding section of a first chuck in a first workstation (5-7) of a shrinkage device, inserting the tool shaft into the tool holder opening and/or removing a tool from it, actively cooling the tool holder section and heating the tool holder section of a second chuck in a second workstation of the shrinkage device separate from the first workstation. Independent claims are also included for the following: An arrangement for thermal clamping and release of tools in shrinkage chucks.
