    A method for manufacturing a diamond tool having a shank, comprising accurately arranging a diamond chip on an upper surface of a base body in such a manner that the cutting edge of the chip projects from the end of the body by a predetermined distance, provisionally securing the chip to the upper surface of the body by means of an adhesive, fitting the body and an insert having an exposed clayish fixture in a U-shaped channel of a lower die to penetrate and position the cutting edge portion of the chip into the fixture of the insert, passing an upper die against the lower die after the fixture is cured, charging a predetermined amount of powder metals into a vertical hole formed in the upper die, pressurizing the powder metals by a press rod which is inserted in the vertical hole while heating the upper and lower dies in order to sinter the powder metals on the upper surface of the body and in the U-shaped channel of the lower die, thereby to rigidly fix the chip to the body, and shaping the body so as to provide a desired form of a shank.

    one
    The invention relates to metal working.
    The known method of making a diamond cutter, in which the sinking j element is surrounded by a powdered material in steel, is then heated and squeezed by hydrostatic pressure to a liquid-plastic state.
    The disadvantage of the known method is that, when heated and compressed by hydrostatic pressure, the diamond cutting element can be displaced from the initial position.
    The purpose of the invention is to increase the strength of a diamond cutter by pre-fastening the cutting element with a clay filler.
    This goal is achieved in that the holder with the cutting element is installed in the V-channel of the lower die, then the cutting element on the holder is additionally secured with a clay filler resistant to the action of the molten metal and high temperatures, then the upper part A stamp in which a vertical hole is made, having a cross section corresponding to the shape and dimensions of the holder, is fed to the bottom, and the powdered material is introduced into the vertical hole of the upper stamp and is sintered, secured. cutting element on the holder.
    FIG. 1 shows a manufactured diamond cutter; Fig. 2 shows a mold for making a diamond cutter, a longitudinal section.
    The tool holder 1 has a roughly processed L-shaped sample 2 onto which diamond 3 is installed. Then, using a projector, a microscope or a template, a predetermined value is reached for the protrusion of diamond 3 due to the front face of sample 2.
    Then, sample 2, the holder and the insert 4 filled with clay fixer 5 are installed in the V-shaped channel 6 of the lower punch 7 so that the end of Zalmaz 3 is in the mix 5 of the implant 4.

    Claims (2)
    [1]
    The lower stamp in the central region has a V-shaped channel b with open ends. The width of the channel is such that the holder 1 fits tightly into it. A sample 2 of the holder 1, a part of the holder 1, and 4 is inserted into the channel 6. The insert 4 has an L-shaped cross section and is filled with a clay fixer 5 so that the surface of the fixer is flush with the insert. The insert 4 moves and is inserted into the channel 6 so that the cutting edge 3 of the diamond 3 enters the fixer 5. Then the fixer 5 is dried and burned, strengthening the cutting edge of the diamond 3, the upper die 8 is pressed against the lower die 7. The upper die 8 is provided with a vertical hole 9 located directly above the sample
    [2]
    2. Then a predetermined amount of powdered metal 10 is loaded into the hole 9. The mold is heated during the pressing of the powdered metal using a pressing rod 11, which fits tightly into the hole 9 of the upper die 8. The powdered metal is thus sintered in sample 2, firmly secured the diamond 3 with the holder 1. After cooling, the holder 1 is removed from the dies 7 and 8 and removed from the fixer. The proposed method allows the diamond to be securely fastened to the holder, eliminating the possibility of accidental displacement or separation of the diamond, which leads to an increase in the strength and durability of the cutting tool. The invention The method of manufacturing a diamond pds, according to which the cutting element is preliminarily fixed in the holder's nest with glue and then fixed with the help of a porous-like material of the material, distinguished by the fact that in order to increase the strength of the cutting element attachment in the V-shaped channel, the lower punch, then the cutting element is additionally secured on the holder with a clay filler resistant to the action of the molten metal and high temperatures, then the top Yu die portion in which are formed a vertical hole having a cross section corresponding to, present the shape and dimensions of the holder, is led to the bottom, and the powdered material is introduced into the vertical hole of the upper die and sintered, cutting element secured to the holder.
