Haas’ DS-30 dual-spindle turning centers are designed to turn both ends of a part in a single setup to minimize part handling, increase throughput and reduce work-in-process. The opposed spindles feature fully synchronized turning for clean part-off and enable on-the-fly part pass-off to reduce cycle times.
The machine has a maximum cutting capacity of 18" × 26" and is equipped with a 12-station hybrid BOT/VDI turret. The main spindle features an 8.3" hydraulic chuck and is powered by a 30-hp vector drive system that provides 275 foot-pounds of torque. The secondary spindle also has an 8.3" hydraulic chuck and is powered by a 20-hp vector drive system that provides 150 foot-pounds of cutting torque. Both spindles turn as fast as 4,000 rpm and have a 2.0" bar capacity. Rapids are 945 ipm on all axes.
The machine also is available in a “Super Speed” configuration (model DS-30SS) with a maximum cutting capacity of 16" × 26" and a 24-station hybrid BOT/VDI turret. The main spindle features an 8.3" hydraulic chuck and is powered by a 30-hp vector drive system that provides 250 foot-pounds of torque. The secondary spindle is identical to that of the DS-30.
Both machines provide a maximum swing of 31.75" over the front apron with a 20.75" swing over the cross-slide. They feature rigid tapping, spindle orientation, a 15" color LCD monitor and a USB port. Options include a belt-type chip conveyor, automatic tool probe, automatic parts catcher and high-pressure coolant systems.
