In addition to the 5 turning tools, the B12VI also comes with 3 live cross tools and 4 front/back ID tools. This is the standard machine for the US market.


Reduced Machining, NC Operation and
Tool Replacement Time


Multi-axis control system for extremely fast data processing

All operations directly controlled by the NC using a completely electronic full servo system

Machining with higher precision is assured even in lengthy operations without being affected by the thermal displacement of a ball screw

A built-in servo motor with an integrated ball screw realizes high speed, fast response operation of the feed system

Tool layout not constrained by machine structure reduces setup and tool replacement times


100% Servo Equipped


Less downtime – eliminates belts, hydraulics, pressure switches, pneumatics, solenoids and other high maintenance components

Shorter cycle times than CAMs

Faster rapid traverses and spindle speeds

Quicker acceleration and deceleration times

Shorter chip-to-chip times and chuck open/close times

40% less floor space

Improved back spindle functionality


Synchronous rotation with main spindle

Front and back work performed simultaneously

S4-digits direct command transmission to 7,000 rpm

0.5 kw motor for excellent acceleration and deceleration

Back spindle has same electrical chuck as front spindle

May be opened and closed as needed, eliminating limitations of a conventional CAM drive


Easy, Safe Operation


Quick, easy, safe way to prove out new programs

Reviews operation in forward and reverse for accurate program editing

Increased reliability due to reduced number of parts

Minimum maintenance and attendance


Quiet Integral Drive Spindle


Drive spindle built-in and fully enclosed

Reduced vibration and noise

Sealed unit enables use of water soluble cutting oil

Typical Parts

For parts up to .47" diameter × 5.31" long per chucking.
