    The invention relates to metal cutting, in particular, to a cutting tool for external machining of rotationally symmetrical products.
    The purpose of the invention is the expansion of technological capabilities through the implementation of rough and precision external machining with a single tool of a symmetrical preform.
    FIG. 1 shows a turning tool in which the guide is provided with at least one guide bar; in fig. 2 is a variant of a turning tool in which the guide is provided with a concentric guide ring.
    FIG. 1 schematically shows a turning tool with a cutting head 1 made as a hollow cylinder and a shank 2. Beginning from the end side 3 of the cutting head 1 in its side wall 4
    notch 5 in the shape of a sector has been made. In the side 6 of the recess 5, a groove 7 is selected in which the cutter plate 8 is inserted, the cutting edge of which projects into the inner space of the cutting head 1. The clamp 9 is inserted into the wall of the cutting head 1 so that it presses the cutter plate 8 to opposite to the direction of rotation of the groove side 7. In this case, the clamp 9 lies on the front face of the cutter plate 8. For accurate installation of the cutter plate 8, those not shown in FIG. 1 adjustment parts, made wedge-shaped at its front end of countersunk screws or fingers with a thread 10 serving as a regulator. The threaded fingers are screwed into the internal threads of the mounting holes 11 of the cutting head 1.

    In the front part of the cutting head 1, on its inner wall, there is provided a guide sleeve 12, extending from at least the length of the cutter plate 8, made of a wear-resistant material, for example, of a hard alloy. It serves to guide the product to be processed and is connected to the side wall 4 of the cutting head 1 so that it cannot rotate inside the cutting head. A longitudinal groove 13 is provided to provide chip exit in the sleeve. serving as a guide bar 14. Preferably, two guide bars are provided, of which one is placed 40 after the cutting edge plate in the direction of rotation of the tool, while the other located against the cutter plate.
    The inner wall of the guide 12 can be made as the inner wall of the rest of the cutting head 1 is tapered. In this case, the cutting edge of the blade of the cutter 8 is directed in such a way that it runs parallel to the inner wall and protrudes into the hollow space of the cutting head 1, as is also the case in the example of FIG. 1 and 2.
    The cylindrical shank 2 (FIG. 1) has an axial first hole 15 for supplying coolant, which is inserted up to the hollow space of the cutting head 1. An inlet channel 16 that is smaller than the diameter of the first hole 15 connects the hollow space to the first hole 15 To supply coolant directly to the cutter plate 8, a second hole 17 is provided in the wall 4 of the cutting head 1, extending generally parallel to the center axis of the turning tool and connecting the first hole 15 through a radial hole. hole 18.
    FIG. Figure 2 shows a second exemplary embodiment of a turning tool, in which identical parts are provided with the same positions.
    The inner side of the guide 12, also designed as a sleeve, has a guide ring 19 which is concentric with the central axis of the turning tool and serves to guide the product to be machined. Instead
    several guide rings may also be provided for one guide ring. In this embodiment, it is possible to form the inner wall.
    the guide sleeve 12 is conical. The inner radius of the guide 12 in the area located in the direction of rotation of the tool of the cutting device is larger than in the other parts. Due to this, the approach is improved.
    coolant and chip discharge.
    Plot with a large inner diameter
    extends, for example, over a sector of 30.
    For machining long products, a needle 5 turning tool 2 of a turning tool can be made the same as a hollow body. In this case, the outer diameter of the shank should be correspondingly increased compared with the examples of execution,
