    The invention relates to the machining of metals by cutting, in particular to the structures of cutting plates used in cutting tools.
    The purpose of the invention is to improve the quality of the treated surface due to better chip breaking.
    Figure 1 shows the front part of the cutter, top view; in FIG. 2, a side cutter; on fig.Z - cutting incisor in the workpiece; Fig, 4 - cutter in perspective; figure 5 is a tool holding the cutter, the cut; figure 6 - part of the tool with the inserted cutter.
    Figure 1 shows a plate in the shape of an equilateral hexagon. Fundamentally, the year also has four, five, or octagonal cutters.
    On the front side of the plate 1 is provided an elevation 2, which serves
    the upper edge of the cutter, as well as the supporting surface sticking, which serves to secure the cutter in the tool.
    Elevation 2 is also made in the form of a versatile symmetric hexagon. The lateral surfaces of elevation 2, serving as chip-stepping steps, extend non-parallel to the lateral cutting edges 3 of the cutter. The elevation is rotated relative to the main body of the tool at an angle a. The angle a can lie within 0 ° and 20 °. It is especially convenient to make the angle a 10 °.
    The outer dimensions of elevation 2 are smaller than the outer dimensions of the plate.
    Between the cutting edges 3 and the chip-cutting steps 4 lie the front faces 5. The front faces are non-parallel to the surface of the elevation 2 and, accordingly, to the back wall 6 of the plate. They,

    when viewed in the direction of their length, are tilted at an angle of / 3, which lies in the range of 0 ° / 3 5 ° and preferably takes a value of 1.5 °, Angle / 3 is also a distortion angle or a correction angle.
    In the exemplary embodiment shown in the drawing, the front face expands in an anticlockwise direction, respectively. The narrowest portion of the front edge is the highest. Therefore, the front face decreases in a counterclockwise direction. Due to the fact that the wide part of the front face itself is low, the next, in the counterclockwise direction, the front face has a small step 7.
    The front faces 5 are not only inclined at their length by an angle fi and decrease in the counterclockwise direction, there is also a decrease across the length. hence, from cutting edges 3 to those serving as chip-cutting steps, there are 4 sides of elevation 2. The reduction has a goal at (0 ° and 15 °). It is preferable to choose an angle value from 3 to 6 °. The angle y is also called the rake angle.
    The side wall of the plate, away from the cutting edge 3, is reduced. Here an angle of 7 ° is chosen. This area forms the back surface 8 of the cutting edge of the plate. The rear surface 8 adjoins the section 9, which deviates from the horizontal, for example, by 15 °. The section 9 becomes more inclined than the rear surface 8.
    When machining the wall of the hole 10 with the aid of a plate, the latter is secured properly in an instrument that is not shown here. The tool moves parallel to the surface of the wall of the hole 10. The plate, together with the tool, rotates so that they move to the observers from the plane of the drawing.
    The material of the wall of the hole 10 is removed with a plate. The section of the side edge 3 of the plate that is decreasing or inclined in the feed direction serves when machining the surface, respectively, of the wall of the opening 10, with the main cutting edge (HS). The side of the side cutting edge 3. adjacent to the side counter-clockwise, in Fig. 3, respectively, to the left, serves as an auxiliary cutting edge (NS). The side cutting edge 3 of the plate is inclined here so that it moves almost parallel to the hole wall being machined. The slope here is shown exaggerated. Auxiliary
    the cutting edge is reduced by 50-100 microns in length. Due to this inclination, it is ensured that the step 7 does not contact with the processed wall of the opening 10 and does not reduce the quality of its surface.
    From fig.Z it is obvious that by changing the angle a, the width of the front face 5 can be changed on the sections of the main (HS) and auxiliary (NS) cutting edges. Depending on the material of the surface to be machined, the width of the cutting edge 3 can be set when making the cutter. It should be noted that the width should not be chosen too small, since this does not cause chip deformation. On the other hand, when the width is set too large, the chips no longer break, so that a chip or spiral appears continuously when the chips are deformed, and if the chips are too long, a chip may arise. This chip can damage the treated surface of the wall of the hole 10.
    The outer dimensions of elevation 2 must be chosen so that the angle 11 of elevation 2 lying on the section of the wall 10 of the main (HS) or auxiliary (NS) cutting edges processing the wall is preferably in the depth of cut shown by the dotted line. This results in an optimal chip discharge mode.
    When the front face forms a plane, the chip removal process depends solely on the distance of the cutting edge 3 to the edge raising surface that serves as a chip-breaking step 4. Because of this, it is especially simple to predict chip chip mode.
    Before making the front face, elevation 2 spreads over the entire common surface of the plate. Front face 5 is machined with a grinding wheel. Since the swarf's step is straight, the grinding wheel also moves linearly along the tool. From this it is obvious that the manufacture of the cutter is relatively simple and can be automated.
    Figure 5 presents a cross-section of the tool in which the plate is fixed. The tool has a body 12 of generally circular cross section. In the housing 12, a recess 13 is made, in which the clamp 14 is installed. The clamp on its part is provided with a notch 15, the contours of which are fitted to the sponge-shaped plate. This is presented respectively in Fig.6. In the heel 15, the plate is reinforced, with the protrusion or the pressing sponge 16 of the grip 14 pressing against the surface of the elevation 2, which serves as the upper edge. The back wall of the plate is then pressed against the ledge 17 of the tool body 12.
    The tool body 12 is provided with a hole 18, which has an internal thread. Coaxially with this hole, there is a hole 19 in the tack, which in turn is provided with an internal thread. A tightening screw 20 is inserted into the holes 18 and 19, which tack 14 in a corresponding manner is attracted to the housing 12 so that the plate is rigidly fixed in the recess 15 .
    According to an example of a tool (Fig. 5), a first guide bar 21 is provided opposite the plates. A second guide bar 22 is located somewhat further in the direction of rotation of the cutter. The guide bars are reinforced in the corresponding 12 slots selected in the housing.
    For the images selected here, for example, the plate lies in the plane intersecting the longitudinal axis of the tool. However, it can be tightened in the tool, rotated so that it lies in the plane intersecting the longitudinal or middle axis of the tool, only with its active cutting edge.
    If the plate is designed as a turning blade, the recess 13 in the clamp 14 must be made so that the cutting edges adjacent to the clamp or to the walls of the notch 15 are not damaged.
    When machining the surface, in particular the walls of the hole, the tool rotates in the direction of the arrow (figure 5), i.e. in the counterclockwise direction. In this case, the tool moves from the plane of the drawing to the observer.
    A horizontal projection of the plate, reinforced in a tack, is shown, the pressing sponge 16 is not shown here.
    The shape of the recess 15 in the tack 14 is fitted to the outer shape of the plate. The recess has two tapered side walls that open inwardly towards the base of the recess 15 in the catch 14. The base is mainly parallel to the outer plane of the tool. The dimensions of the recess 15 are chosen so that the two side edges 3 of the plate fit snugly to the conical side walls of the notch 15. To compensate for the tolerance on the size of the plate, it is not adjacent to the bottom of the notch 15, but only to the side walls adjacent to the base inclined to it. Due to this, the plate finds reliable support in the tack 14 of the tool.
