Shimada Kitako B6 Series – 6 Spindle Automatic Lathes

High-Speed 6-Spindle Automatic CNC Lathes for Continuous Bar Production

The Shimada Kitako B6 Series consists of four camless, 6-spindle horizontal automatic lathes designed for continuous, high-output bar work. Each spindle performs a different phase of the machining cycle, while the spindle carrier indexes 60ยฐ between operations โ€” enabling fully synchronized, uninterrupted production with extremely low idle time. The combination of multi-spindle efficiency and CNC-controlled slides gives manufacturers both high-volume output and modern process flexibility.

Each model supports up to three CNC 2-axis slides, providing synchronized 6-axis capability for contouring, drilling, grooving, and cutoff operations. The B6 Series merges the speed of traditional screw machines with the precision, programmability, and rapid setup advantages of CNC. Standard equipment includes an IEMCA or Pietro Cucchi compact automatic bar feeder, remnant ejection, and quick-change tooling, making the B6 platform suited for just-in-time manufacturing and lights-out automation.
