Abstract
The invention relates to a tool holder comprising a tool receptacle for frictionally clamping a tool shaft. A sleeve is arranged between the tool shaft and the clamping surface of the tool holder, said tool holder applying pressure to the tool shaft via the sleeve, producing the friction fit. At least one of the bearing surfaces of the sleeve is interrupted by open surfaces that are designed and arranged such that they form the damping cavities.
Claims17
A tool holder, comprising:
- a tool receptacle for frictionally clamping a tool shank;
- and
- a sleeve situated between the tool shank and a clamping surface of the tool holder, with the tool holder applying pressure on the tool shank via the sleeve and thus producing a frictional engagement;
- wherein at least one bearing surface of the sleeve is interrupted by open micro-recesses that constitute a spring element, which experiences solid compression after a definite short spring travel, wherein the depth of the open micro-recesses is less than or equal to 0.1 mm, and wherein the open micro-recesses are interrupted in a circumferential direction by non-recessed areas.
