Embodiment Construction

[0035] exist figure 1 In , a tool 1 according to the invention is shown in connection with the machining of a workpiece 2 . The tool is realized in the form of a turning tool, the main part of which is the blade plate 3 which serves as a holder or base body for an exchangeable cutting insert 4 . The workpiece 2 is cylindrical and rotatable in the direction of rotation R. As shown in FIG. By feeding the tool 1 longitudinally in the feed direction F during simultaneous rotation of the workpiece, a circumferential groove 5 can be provided in the envelope surface of the workpiece, the width of which is determined by the width of the main cutting edge comprised in the cutting insert 4 , while the depth of the groove 5 is determined by how far the blade and its cutting inserts are fed into the workpiece.

[0036] figure 1 The processing method illustrated in is a grooving operation.

[0037] exist figure 1 , also shows a key 6 with an eccentric body 7 by means of which a clamp...

Abstract

The invention relates to a chip removing machining cutter, a cutting board clamping blades and a replaceable blade, and provides a cutter for chip removing machining of metal blanks. The tool comprises a cutting board and a replaceable cutting blade mounted in a seat, which is delimited between a bottom support and an elastically resilient clamping finger. The cutting blade includes an upper side, in which there is included a front rake surface as well as an application surface, which is positioned behind the same and against which the clamping finger is pressed. In the clamping finger, a flushing channel is included to spray a cooling medium toward the rake surface, a front nose of the clamping finger facing a shoulder, which is formed between the rake surface and the application surface and has the purpose of protecting the nose from chips. According to the invention, said shoulder consists of two knobs, which are mutually separated by a central notch, via which cooling medium can pass from the flushing channel toward the rake surface.

Description

technical field [0001] In a first aspect, the invention relates to a tool intended for cutting removal machining in grooving or parting, a tool of the type comprising a blade and replaceable cutting inserts, the replaceable cutting blade The insert is mounted in a seat located at the end of the blade and delimited between the bottom support and the resiliently resilient clamping fingers, said cutting insert comprising a front side, a rear side , two side surfaces, a bottom side and an upper side, the upper side includes a rake surface and an application surface, the rake surface is arranged closest to the front side, the application surface is arranged at the front behind the cutter face, and against which the clamping finger is pressed against said application face, the clamping finger comprises a flushing channel which opens towards the cutting insert in order to spray cooling medium to the rake face and the main cutting edge Above, the main cutting edge is formed between t...
