FIELD: tool production. SUBSTANCE: mill (broach) is relieved on lathe-relieving machine in which spindle it is fastened. Relieving is made by an abrasive disk which is set in synchronous rotation, reciprocating and axial movement. The mill (broach) is made in the form of a chain built up from joined links with cutting members in the form of two sprockets: drive and driven. The disk is axially moved one step per one revolution of the mill, during this step a number of reciprocating movements is made which number is equal to the number of teeth of the drive sprocket. EFFECT: improved quality. 2 dwg
