    The invention relates to metal working, in particular to a cutting tool. The aim of the invention is to improve the quality of the treated surface and productivity by increasing the accuracy of balancing each cutting insert. The tool case 1 has a hole 2 in which a cylindrical balancing element with a bevel 3 with a locking collar 4 and an axial hole 5 is placed. In the aperture 2 a hub of the tool holder 9 with a cutting insert 10 is attached. In the aperture 5 there is a pin 7 of the support element 6. Using the adjusting screw 11, located in the threaded hole 8 of the cylindrical support element 6, the movement of the cutting insert 10 is controlled. At the same time, the support element 6 is supported on the balancing element of a cylindrical shape with one-sided m bevel that its retaining flange 4 is supported on ledge 2. openings balancing element is prevented from turning out of the established position of the screw 12. The longitudinal axis of the balancing element is angled relative to the axis of rotation of the tool. 2 hp f-ly, 1 ill.

    专利说明:

    The invention relates to metalworking, in particular to a cutting tool.
    Known milling cutter, in which the balances in the yid of steel balls, fractions or deformable masses are located in the channels lying opposite the cutting inserts, and are closed with screw plugs. The balancing is done in such a way that those who are in the interconnected channels of the opposing A can / can move by pulling and loosening the plugs located on the base, from the position to the center of gravity of the instrument, while there is no equilibrium, The channel system for the arrangement of counterweights is used only for a single-blade milling head, since it occupies almost the entire cross section of the half of the mill body located opposite the cutting insert (German Patent No. 947926, class 38e 1, 1956).
    The aim of the invention is to improve the quality of the machined surface and productivity by improving the accuracy of balancing of each cutting insert.
    The drawing shows the proposed mill.
    In the tool body 1 there is a fixing hole 2 of a stepped diameter so that its longitudinal axis is inclined to the axis of rotation of the tool body at an angle of more than 0 °, and the fixing hole 2 on the clamping side of the tool body 1 is smaller in diameter. In the fixing hole 2 are placed a cylindrical counterweight with a one-side bevel 3 with a locking collar 4 and an axial hole 5, a supporting element of a cylindrical shape 6 with a trunnion 7 and a threaded hole 8, the sleeve of the cutting tool holder 9 with the cutting insert 10. The sleeve of the cutting tool holder 9 is attached with the cutting insert 10 using a clamping element (not shown) in the fixing hole 2. Using the adjusting screw 11 located in the threaded hole 8 of the cylindrical support element 6, the movement of the cutting insert in the plane STI In this case, the cylindrical supporting element 6 rests on a counterweight of a cylindrical shape with a one-sided bevel, which with its retaining collar 4 rests on a protrusion formed by two different diameters of the fixing hole 2. The counterbalance of a cylindrical shape with a one-sided bevel 3 is prevented from twisting from an installed position by means of a clamping screw 12. The clamping screw 12 is an additional safety element. Its use is not necessary, since the counterweight is cylindrical in shape with a one-sided bevel by means of a cylindrical supporting element 6 resting on it, when the clamping screw 10 is tensioned, it is pressed against the protrusion 13. The cylindrical-shaped supporting element 6 is provided with a pin 7 located in the axial hole 5 of the cylindrical counterweight with a one-sided bevel in order to maintain the thickness and, consequently, the mass of the tool body as small as possible with a sufficient number of thread steps of the threaded hole 8. After installing the tool holder bush and the cutting insert 10, they are pre-tensioned and, using the setscrews 20 and 11, are adjusted for movement in the plane. Then the toolholder sleeve and the cutting insert 10 are tightened tightly. For the subsequent balancing of the imbalance, the adjusting 11 and clamping 12 screws 25 are loosened so that the counterweight of a cylindrical shape with one-side bevel 3 can be rotated around its longitudinal axis using appropriate auxiliary means.
