FIELD: machine building.
SUBSTANCE: stated invention is related to machine building, namely to devices for fixation of polishing wheel. On aligning section of polishing spindle rotor, main body has indent, from which two strong protrusions protrude inside it. Mount element in the form of cam disk rests on two support pins, which are provided in indent of main body. Cam disk has engagement hole for rotation tool. In process of cam disk rotation it either approaches aligning section or moves away from it. Movement of main body along aligning section is carried out with cam disk pushed in, on completion of alignment it is installed on aligning section. Strong protrusions and cam disk are preferably located so that line of cam disk action lies in the middle of angular distance between strong protrusions.
EFFECT: improved reliability and accuracy of alignment.
