摘要

The grinding machine has at least one row (6,6') of cutters (7) originating from each end face (4,5) of the cutting drum (1) and located along a helical line reaching to the middle (11) of the drum. The rows of cutters of one end face to the rows of cutters to the other end are fitted with uniform offset spacing in relation to one another in the circumferential direction. The helical line occupies an angle of about 45 deg opening to the middle of the cutting drum.
