摘要:
The invention relates to a cutting tool having a holder (12) having a slot-shaped, arc-shaped receptacle (16) having bottom and top contact surfaces (36, 38) attached to rigid clamping jaws (18, 20) of the holder (12) for receiving (16) a cutting insert (14) and a cutting insert (14) having an arc-shaped shaft (22) having a bottom and top contact surface (32, 34) which is interchangeably arranged in the receptacle (16), and a cutting head (24), having a cutting edge (26), arranged on a tool-side end (44) of the shaft (22), wherein the arc-shaped receptacle (16) and the arc-shaped shaft (22) each extend beyond at least 90°, measured on the bottom contact surface (36) of the receptacle (16) or the bottom contact surface (32) of the cutting insert (14), wherein the receptacle (16) extends beyond a larger angle range than the shaft (22) of the cutting insert (14) and wherein the shaft (22) is held in the receptacle (16) such that the holder-side end (28) of the shaft (22) is spaced apart from the holder-side end (30) of the receptacle (16).
摘要:
According to the invention a tool system for machining a workpiece is recommended, having a cylinder-shaped retaining shank (12) that has a cutting head holder (16) on an end surface (14) facing the workpiece, a drive mount (20) on an end surface facing the drive (18), a cutting head (22) having at least one cutting edge (24), a cutting head hub (26) corresponding to the cutting head holder (16) on the retaining shank (12), a tool coupling (28) with a tool interface (30), and a coupling hub corresponding to the drive mount (20), wherein the coupling hub (32) and/or the cutting head hub (26) have elevated areas (34, 50) with contact surfaces (36, 52), wherein the elevated areas (34, 50) are distributed in an arrangement in both the circumferential (38) and longitudinal directions of the coupling hub (32) and/or the cutting head hub (26), wherein the contact surfaces (36, 52) make contact on support surfaces (42, 56) on the drive mount (20) and/or on the cutting head holder (16) on the retaining shank (12), and wherein the drive mount (20) and/or the cutting head holder (16) is permanently connected to the coupling hub (32) and/or the cutting head hub (26) by means of a joining material (46) in intermediate spaces (44, 58) between the elevations (34, 50).
摘要:
The present invention relates to a tool for the machining of a tool, and also to a corresponding holder for this type of tool. In order to achieve improved cooling, a tool is proposed with a cutter insert (14a) with at least one cutter (22a, 23a, 24a) and with a holder (12a) with a cutter-insert receptacle (18a) arranged in the region of the workpiece-facing face side (16a) of the holder, in which the cutter insert (14a) has been arranged, where the arrangement has, in the holder (12a), a coolant bore (28a) which leads to at least one coolant outlet (44a), which has been arranged at the workpiece-facing face side (16a) of the holder (12a) laterally alongside the cutter-insert receptacle (18a) and has been designed in such a way that coolant is discharged in the direction of the cutter insert (14a).
