ABSTRACT:
An apparatus for cutting off cast parts from a cylindrical runner of a casting body comprises a slidable mount supported on a bed, holding means provided on the slidable mount for supporting and indexing the casting body and a cutting grinder supported up and down movably on the bed. During a forward movement of the slidable mount in the axial direction of the casting body, cast parts arranged in an axial row are cut off successively. After this cutting, the casting body is indexed to the next cutting position and by a rearward movement of the slidable mount cast parts arranged in the next axial row are cut off. Thus cast parts on the outer periphery of the cylindrical runner of the casting body which usually is manufactured by precision casting may be cut off from the runner in the most simple and efficient way.
