Shimada-Kitako 2SI MKII Series – Twin Spindle Single Turret Lathes
Twin-Spindle, Single-Turret CNC Lathes for Simultaneous OP10/OP20 Machining
The Shimada-Kitako 2SI MKII Series consists of twin-spindle, single-turret CNC turning centers designed to machine both ends of a workpiece at the same time. While one spindle completes OP10, the second performs OP20, eliminating load/unload idle time and allowing finished parts to exit the machine every cycle. Once both operations are complete, the turret indexes 180°, instantly swapping sides and repeating the process for uninterrupted production flow.
Designed for flexibility, the 2SI MKII Series supports 6″, 8″, and 10″ chuck configurations, including asymmetric setups when part families differ in size. Options such as live tooling, Y-axis, and servo tailstock transform the platform into a compact mill-turn solution capable of handling complex parts with fewer secondary operations. The externally mounted chucks and automation-friendly layout simplify setups, shorten changeovers, and allow direct robot integration without increasing required floor space.
