The Haas DS-30Y is a dual-spindle Y-axis CNC lathe with a reputation for straightforward, dependable operation that has made it a staple in job shops and production turning cells. This 2019 Haas DS-30Y Y-axis CNC lathe pairs a main spindle rated at 4,500 RPM and 30 HP, with an A2-6 spindle nose, 3.5 inch spindle bore, 3.0 inch bar capacity, and a 10 inch 3-jaw chuck, with an opposed sub-spindle carrying an 8.3 inch chuck on an A2-5 nose. A single 12-station BMT65 turret with live tooling at a 1:1 drive ratio works with the Y-axis and C-axis to drill, tap, and mill off-center features, so a part can be turned, milled, handed off to the sub-spindle, and back-worked in one setup. The machine runs the Haas Next Generation Control, and this unit is equipped with a Haas bar feeder for unattended bar work, a chip conveyor, and a 55-gallon coolant tank. For shops running shafts, fittings, hydraulic components, and other turned-and-milled parts from bar, the DS-30Y is built to deliver done-in-one production in a compact footprint.
Compared with earlier Haas turning centers such as the SL-30 and ST-30, which are single-spindle machines that need a second operation or a second machine to finish the back side of a part, the DS-30Y adds an opposed sub-spindle so the part is transferred and completed in the same cycle. Against the Haas DS-30, the dual-spindle model without a Y-axis, the DS-30Y adds Y-axis travel to the live-tooled turret, opening up off-center milling, flats, slots, and cross holes that a C-axis-only lathe cannot reach. The 2019 build also carries the Haas Next Generation Control, a step up from the Classic Haas control on older lathes, with a larger touch-friendly interface, faster processing, and improved program management. The result is a meaningfully more capable machine, not just a newer one: fewer setups, fewer secondary operations, less handling, and more complete parts per shift from a single spindle-to-spindle cell.
