<p>A machine tool for abrasive machining comprises an abrasive instrument (1) and a device for creating the pressing force in the cutting zone provided with a casing (3) with guides in which are mounted , with the possibility of reciprocating movement, tail spindles (4) with heads (5) for transferring the pressing force to the cutting instrument (1) and a feeding mechanism (14) mounted on the casing (3). In the device for creating the pressing force the tail spindles (4) are interconnected by means of an elastic element (11) rigidly connected to the feeding mechanism (14), the latter being capable of damping the elastic element (11) in the back and forth feeding directions. According to another variant, in the device for creating the pressing force the tail spindles (4) are interconnected by means of at least one elastic element (11a) rigidly connected to them, whereas the feeding mechanism (14) is connected to the elastic element (11a) and is capable of damping the elastic element (11a) in the back and forth feeding directions.</p> |
