тельно его продольной оси. Фиксаци дорна от проворота относительно замка происходит за счет сил трени -между торцом заднего конца гильзы и замком через дорновое кольцо. Предложенное устройство осуществл ет фиксацию дорна относительно оси его вращени без участи рабочего дорнового или специального устройства, облегча тем самым ручной труд.its longitudinal axis. Fixation of the mandrel from rotation relative to the lock occurs due to the forces of friction - between the end of the rear end of the sleeve and the lock through the mandrel ring. The proposed device fixes the mandrel relative to its axis of rotation without the fate of a working mandrel or special device, thereby facilitating manual labor.
