    EO U1 The invention relates to the study of the abrasive grain wear characteristics by scratching, in particular, to a scratching device for testing abrasive grains on the nose and nose on a surface grinding machine. There is a known scratching device for testing abrasive grains for wear on a surface grinder which contains a flange fixed to the machine spindle, fixed on the last circle f, mounted on a circle, a force measurement unit with a zen holder, a signal transmitter and a device mounting device on the machine l. A disadvantage of the known device is the lack of reliability of its operation, which is due to the need to use a grinding wheel for sample preparation by stripping, grinding and polishing and making a circle for scratching, i.e. frequent replacement of circles is required. The aim of the invention is to increase the reliability of the device for testing abrasive grains for wear on a surface grinding machine. This goal is achieved by the fact that the scratching device for testing abrasive grains for wear on a surface grinding machine, attached to the spindle hundredth flange fixed on the last circle, Circular mounted force measurement unit with a grain holder, a signal transmitter and means of mounting the device on a machine; it is fitted with an additional flange installed on the machine spindle With a grinding wheel and a measuring unit, it is made in the form of a piezo-square and a titanium pre-tensioning screw, the cone-shaped recess is made in the screw head, in which the grain holder is placed, in the recess there is an internal thread and a grain holder, and on the flanges there are end grooves for balancing. Figure 1 shows the proposed my device; Fig. 2 shows a force measurement assembly; Fig. 3 shows a device installed on a machine. The device {figure 1) contains flag 1, circle 2, node 3 of measurement of force, holder 4 of grain 5 {figure 2), transmitter 6 of signes and means 7 of mounting the device on the machine. The force measurement unit 3 is made in the form of a piezoelectric screw and screw 8, made of titanium preloading the latter, screw head 8 is made conical angle 9 to accommodate the holder 4 of the grain 5. In the recess 9 an internal thread 10 is made, interacting with the nut 11 of the holder 4. The flange 1 has an end groove 12 for balancing. The signal transmitter b is fixed to the flange 1 by means of the cover 13. The screw 8 is equipped with a nut 14 to tighten the piezo quartz to the required pre-tension. The flange 1 is mounted on the sleeve 15c. spline 16 and secured with screws 17 on an additional flange 18 provided with a groove 19 for balancing. A grinding wheel 20 with a rubber coating 21 is installed between the sleeve 15 and the additional flange 18, which serves to carry out any treatment up to polishing by replacing the belt 22 (FIG. 3). The key 23 (Fig. 1) serves to secure the sleeve 15 on the spindle 24 of a surface grinder comprising a spindle head 25, a lever 26 for tensioning the belt 22, a guide roller 27 and a compression spring 28. The holder 4 is made of an alloy based on nickel, and the screw 8 is made of titanium. The transmitter B of the signals is made in the form of a rotary transmitter. The grooves 12 and 19 are made in the form of a dovetail. The proposed device works in the following way. The test abrasive grain 5 is fixed in the holder 4 and is set at a predetermined place around the circumference of the circle 2 for scratching. The normal and tangential force charging signals are guided by the power measurement unit 3 through the rotary transmitter 6 to a charging amplifier (not shown) and recorded with a 4 oscilloscope (not shown), one of the power signals showing the normal force distribution and the other strength A feed setting of, for example, 40 micrometers is achieved in that the grain 5 is radiated at the center of the workpiece without moving the machine table. Radiation signals to the eye of the observer about the first contact of the grain 5 with the product being processed and is also recorded by means of a small force, shown on a storage oscillograph (not shown). Then, the position of the table (not shown) of the machine, on which the surface-ground product is located, is changed so that at the beginning of the workpiece, the product begins the scratching process. As the scratch circle 2 rotates clockwise, the table performs a working chorus in the opposite or same direction. The feed remains constant. Thus, a scratch mark is made on the surface of the workpiece.
    A maximum of four scratch marks with equal spac13 are produced.

    The positive effect is due to the increased reliability of the device for testing abrasive grains for wear.
