The JIS A2-8 spindle has an 80 mm (3.15 in) bore and 120 mm front bearing, and runs from 25 to 3,000 rpm in two infinitely variable ranges. The spindle motor is rated 15 kW (20 hp) for 30 minutes and 11 kW (15 hp) continuous, giving 420 lbf-ft of torque in the low range. A 12-station V12 hydraulic turret takes 1 inch square OD tools and 1.5 inch ID holders and indexes in 1.1 seconds. Rapid traverse is 20 m/min on X and 25 m/min on Z.
