Definitions

• the invention relates to a tool with a tool holder which can be fixed in a machine holder of a machine tool and on which a cutting plate held non-rotatably in a holder of an intermediate plate is fastened, the intermediate plate being rotatable in an arcuate recess in the tool holder and being lockable in several angular positions relative to the tool holder.
• a tool of this type is known from DE-OS 33 03 058.
• the intermediate plate can be rotated about an axis of rotation in a recess in the tool carrier.
• the set angular position of the intermediate plate is achieved by a shoulder with serration which engages in a corresponding counter-toothing in a receptacle of the tool carrier.
• the toothing determines the stepped rotation of the intermediate plate with respect to the tool holder and thus the setting of the cutting plate to different cutting angles.
• the setting of the toothing of the intermediate plate and tool holder is locked by means of a clamping screw which runs transversely to the adjustment axis of the intermediate plate and which also fixes the intermediate plate on the tool holder.
• the cutting plate and the intermediate plate are fastened to the tool carrier by means of a common fastening screw, that the intermediate plate can be rotated about the fastening screw in the recess of the tool carrier, that the intermediate plate or the recess carries a shoulder, the one in several.
• Recesses of the same cross-section of the recess or the intermediate plate can be used, and that the recesses for the attachment are arranged in a predetermined angular division with respect to the axis of rotation defined by the fastening screw.
• the unve rrehba re definition of the cutting insert in the intermediate plate is achieved in one embodiment in that the preferably triangular insert is held in an acute-angled receptacle of the intermediate plate and protrudes from the receptacle with two corners.
• the machining process with the cutting plate is not hindered by the fact that the top of the cutting plate is flush with the upper side of the intermediate plate and the upper side of the tool carrier.
• Fig. 1 in plan view of the tool consisting of cutting plate, intermediate plate and tool carrier and
• Fig. 2 shows a section through the tool of Fig. 1, along the line II-II.
• the tool carrier 1 is in a manner not shown in the
• the tool carrier 1 On the top, the tool carrier 1 carries the concave recess 9, which closes in a circular arc and receives the intermediate plate 2 with the convex side.
• the circular arcs are matched to the axis of rotation, which is formed by the fastening screw 4, which fixes the cutting plate 3 together with the intermediate plate 2 on the tool carrier 1.
• the cutting plate 2 has a triangular shape and is non-rotatably fixed in the acute-angled receptacle 10 of the intermediate plate 2 that two cutting corners protrude from the receptacle 10.
• the two sides of the receptacle 10 open into the bore 5, so that the cutting plate 2 fits snugly on the sides of the receptacle 10.
• the intermediate plate 2 carries on the convex side, which faces the concave side of the recess 9 of the tool carrier 1, the triangular projection 6, which is inserted into a recess 17 with a corresponding cross section in the recess 9 and holds the intermediate plate 2 non-rotatably on the tool carrier 1 .
• the recess 9 has a plurality of recesses 17, which are preferably made in a predetermined angular division, so that the intermediate plate
• the cutting angle of the cutting plate can thus be made
• the fastening screw 4 only needs to be loosened and the intermediate plate 2 to be fixed in a different angular position in the recess 9 of the tool holder 1.
• the fastening screw 4 is tightened, which is screwed into the threaded receptacle 11 in the tool holder 1, the cutting plate 3 and the intermediate plate 2 are held on the tool holder 1 in a non-rotatable manner.
• the tops of the cutting plate 3, the intermediate plate 2 and the tool carrier 1 are flush so as not to impede the cutting process.
• the extension 6 and the recesses 7 can also have other shapes and cross sections, and can also be interchanged on the tool carrier 1 and the intermediate plate 2.
