PURPOSE:To carry out mechanically efficiently cutting operation by removing and arranging burrs of a molding such as a core with reversible steel wires and projections with reversible grinding wheels energized elastically. CONSTITUTION:A support plate 3 is lowered along struts 2 to arcuately reverse steel wires 14 through linkages 8, 9 and 10 by operating an air cylinder 6 while cutting burrs 27 existing in holes of a core 26 or the like. Also, unnecessary projections 28 existing on the rear surface of the core 26 are cut and removed by moving grinding wheels 22 supported by the support plate 16 to position in which the projections 28 exist and arcuately rotating said grinding wheels through a linkage 20 by operating a cylinder 17 in the same manner as the burrs are removed. |
