sb-12reiSB-12R type E

A new model for machining small-diameter workpieces added to the lineup of SB-R series with a wide range of choice

A build-in motor (max. 15,000 min-1) is employed in the main spindle .

A tool post, for a 5-spindle cross drll unit (max. 10,000min-1) appropriate for machining small-diameter workpieces, can be selected according to machining parts .

The 4-spindle backworking unit especially designed for rear-end working can accommodate a power tool drive unit (optional) to improve machining performance on the rear end. 

The main spindle/sub spindle C-axis control is supplied as standard equipment.
