Spannfutter zum Spannen von Werkzeugen durch Schrumpfsitz

摘要

The invention relates to a clamping chuck for clamping tools by shrink-fit. Said clamping chuck has a chuck body (1) in which a central seat (2) is configured which receives the shaft of a tool (W) to be clamped. The tool holder (6) and the stop element (3) are linked with each other at an axial distance from the bearing surface (4). They consist at least partially of materials with different thermal expansion coefficients so that, if the temperature changes, the seat (2) is expanded and the tool holder (6) dilates to a greater extent than the stop element (3).
