Tool system () comprising a tool holder () that includes an insert seat () for accommodating an insert () having a depression (), further comprising a clamping element () that has an opening () for accommodating a clamping means (), and a projection (), and comprising a mechanism (functional dimension (Fx) that limits the linear mobility of the clamping element (). This ensures that a disposable insert () can be repeatedly securely clamped.

Tool system

Tool systemcomprising a tool holderthat has an insert seatfor receiving a cutting insert, and comprising a clamping elementthat has an openingfor receiving a clamping means, an interfacebeing arranged between the tool holderand the clamping element, and channels for the purpose of cooling by means of a fluid being arranged in the tool holderand the clamping element, and a sealing meansbeing arranged in the region of the interface

The invention relates to a carrier tool () comprising a clamping element () with a clamping element projection () and comprising a cutting insert () with a clamping recess () on the cutting insert surface () for machining workpieces. The clamping recess () has an annular indentation () with a recess base (), and the indentation () transitions from the recess base () into the cutting insert surface () via an annular surface (). The indentation () surrounds an elevation (), the tip () of which lies above the recess base () and below the cutting insert surface (). The clamping element projection () engages into the clamping recess () and thus clamps same on the carrier tool (). In order to allow a pre-centering of the contour of the clamping element projection () and the contour of the clamping recess () when closing the clamping element (), the contours of the clamping element projection and the clamping recess thus engaging into each other in a form-fitting and precisely positioned manner, the clamping element projection () has an annular contour () which surrounds the elevation () in the clamped state but does not contact the elevation and rests solely on the annular surface ().

Carrier tool, cutting insert, and clamping element

A cutting tool system comprising a carrier tool, a cutting plate having a clamping recess and a clamping element with an associated clamping bolt, wherein on the underside of the clamping element, which underside faces the cutting plate, an engagement element is arranged that is in clamping contact with the clamping recess in the engaged state and thereby anchors the cutting plate, and the clamping element is guided via a chamfer in such a manner that when tightening the clamping bolt, the clamping element is pulled in the clamping direction.
