2 3 The direct-drive rotary guide bushing enables higher spindle speed. BH20/BH20Z Overrapped machining with the back spindle ■Maximum spindle speed: 10,000min-1 ■Machining stroke: 170mm (built-in motor drive) Improved geometric accuracy, dimensional accuracy, and surface roughness with high speed and quiet operation ■Improved rotation and phase synchronization accuracy with the main spindle ■The main/back spindle follow-up function enables Guide bushing type or guide-bushing-less type selectable rounding cut-oﬀ. according to the workpiece (Option) BH20/BH20Z

Guide bushing spindle Guide-bushing-less ■Stationary guide bushing ■Guide-bushing-less unit structure structure ■Direct-drive rotary guide bushing device ■Possible to switch between the guide bushing type and guide-bushing-less type so the most suitable operation for the workpiece length can be chosen. ■The spindle without a guide bushing does not require ground bars, enabling high

speed and high precision when machining cold drawn bars. １８０ mm ３０ mm Remnant length Remnant length The shortest possible remnant length is 30 mm. (Carrier type rotary guide bushing device) BH20/BH20Z back spindle

"Double Spindle" structure enables powerful machining that produces blue chips. BH38 Shortened indexing time Higher rigidity of rotary tools "Double Spindle" structure ■The double spindle structure that integrates the guide bushing and the spindle ■Turret indexing time by the servo motor: 0.3 sec ■20% increase in productivity thanks to enlarged (in perfect synchronization) enables high accuracy and powerful machining. ■Chip-to-chip time: 2 sec (4 sec on the conventional model) drive shaft and bearing. ■Since water-soluble coolant can be used, there is no danger of ﬁre or greasy ■Non-lift indexing turret reduces mechanical shocks. ■Bore diameter on turret: 40 mm (32 mm on conventional models) fumes even when heavy duty machining is performed. ■Short remnant length (150 mm + workpiece length)

■3 times faster feed rate, 3 times greater productivity Independent drive
