The device is intended for sharpening on grinding machines of models VZ-318, VZ-318E, VZ-818, VZ-818E worm cutters according to GOST9324-80. Division into the tooth is carried out on a dividing disc. On the device it is possible to sharpen another tool on the front and rear surfaces with the angle of installation of the sinus ruler up to 10°.

When sharpening the tool with the installation of a sinus ruler up to 45°, it is necessary to use hydroficated machines of the mod. VZ-318E, VZ-818E. With the use of the tool, it is possible to sharpen the tool with straight grooves. For this, the sinus ruler is set parallel to the longitudinal displacement of the table, i.e. In the zero position.
