Piston OD oval machining + preparatory machining two turret

These machines are based on the process integration type piston machines, and they further raise the productivity of up to 12" (305 mm) pistons.

A process integration type machine in which non-circular machining function is integrated in the 2-turret 4-axis CNC lathe so as to provide a high efficiency machining of pistons, etc. in variable-kind variable-lot flexible productions
