Abstract

Collet chuck having a plurality of jaws which are radially movable with respect to one another and which, with their clamping faces, form a common receptacle for guiding a rod that is to be machined in a lathe, characterized by a blind hole which is routed in at least one jaw from the outer face, opposite the clamping face of the jaw, in the direction of the clamping face, with a blind-hole bottom which is delimited on the one hand by the clamping face and on the other hand by the blind hole and which, through wear of the clamping face, is configured to effect the formation of a through-hole indicating the wear of the collet chuck.

Abstract

The invention relates to a guide bushing system (100) comprising a guide bushing (10) configured to receive a guide clamp (20), a plurality of guide clamps (20) of different types which can be introduced into the guide bushing (10), a drive configured to carry out an axial movement of at least one of the guide clamps (20) within the guide bushing (10), and a plurality of spindle caps (40) each adapted to at least one type of one of the plurality of guide clamps (20), wherein each spindle cap (40) of the plurality of spindle caps (40) can be connected to the guide bushing (10) for cooperation with the guide clamp (20) to which the respective spindle cap (40) is adapted.

Abstract

Collet chuck (10) having a plurality of jaws (20a, 20b) which are radially movable with respect to one another and which, with their clamping faces (30a, 30b), form a common receptacle for guiding a rod that is to be machined in a lathe, characterized by a blind hole (50) which is routed in at least one jaw (20a, 20b) from the outer face (40a, 40b), opposite the clamping face (30a, 30b) of the jaw (20a, 20b), in the direction of the clamping face (30a, 30b), with a blind-hole bottom which is delimited on the one hand by the clamping face (30a, 30b) and on the other hand by the blind hole (50) and which, through wear of the clamping face (30a, 30b), is configured to effect the formation of a through-hole indicating the wear of the collet chuck (10).

Abstract

A collet includes a plurality of clamping jaws movable relative to one another, at least one recess provided in one of mutually facing side faces of adjacent clamping jaws, and a spring inserted into each recess and supporting the adjacent clamping jaws resiliently relative to one another, and a seal sealing the gap between two side faces of adjacent clamping jaws, with the said seal having a fastening portion engaging in the at least one recess.

Abstract

The invention relates to a guide bushing (10) for guiding a material rod, comprising a collet chuck (30) mounted in an axially displaceable manner in a collet chuck receptacle (20), and an actuator (40) configured for the axial movement of the collet chuck (30), characterized by at least one sensor (50), which detects, directly or indirectly, the axial position and/or the radial expansion of the collet chuck (30) in the collet chuck receptacle (20) and/or the chucking power.
