FIELD: abrasive treatment.
SUBSTANCE: invention can be used for full treatment of short and/or bar-shape processed details by grinding two parallel end surfaces and external contour of side surfaces with short tact periods. Grinding machine has two grinding spindles with parallel rotation axis located in the tandem set at common grinding spindle assembly. Mentioned grinding spindles are together applied to the cutting-in in the X direction. When interacting fixing and transporting devices the two processed details are grinded at least in parts with equal time. Two end surfaces of one processed detail are grinded in one position. In the second processing position the finishing non-round grinding of outer contour of the second processed detail is made the end surfaces of which were finally grinded before.
EFFECT: increased treatment effectiveness.
