Overview
The Haas DS-25Y is a dual-spindle turning center with a Y axis and live tooling, built around a 10 in (254 mm) main chuck, 3 in (76 mm) of bar capacity and a 30 hp (22.4 kW) main spindle that peaks at 300 ft-lbf (407 N·m) at 500 rpm. Its work envelope matches the DS-20Y: both turn up to 11.75 in (298 mm) in diameter and 22.5 in (572 mm) long. What changes is the spindle. The DS-20Y is rated 20 hp (14.9 kW) and 150 ft-lbf (203 N·m) with a 4,000 rpm top speed, while this machine has twice the torque and gives up speed, topping out at 3,400 rpm.
The second spindle is smaller than the first, and that shapes how a job is split between them. The table lists a 6.5 in (165 mm) sub-spindle chuck on an A2-5 nose, 15 hp (11.2 kW) and 100 ft-lbf (135.6 N·m) at 870 rpm. It runs to 5,000 rpm on its own, but synchronized with the main spindle for a part hand-off it is limited to 3,400 rpm. Plan the heavy roughing for the first operation and keep the back side for lighter cuts.
Milling goes through a 12-station BMT65 turret with live tools to 4,000 rpm on a 1:1 drive, and a Y axis of ±2 in (±51 mm). The main C axis positions to 0.01° and its brake holds 250 ft-lbf (339 N·m). For the sub-spindle the table carries two entries, a C axis with interpolated motion at 0.01° and a positioning-only form at 0.02°, so confirm which one a quoted machine has.
Thrust is 5,100 lbf (22,686 N) in Z, 4,100 lbf (18,238 N) in X and 2,300 lbf (10,231 N) in Y, which makes Y the axis to protect when milling off centre. The machine ships at 12,700 lb (5,761 kg) on a 143 × 90 × 92 in (363 × 229 × 234 cm) pallet and needs 70 A at 220 VAC or 35 A at 440 VAC three-phase. Haas lists a starting price of US$176,995.

Strengths & Limitations
Strengths
- 30 hp (22.4 kW) main spindle with 300 ft-lbf (407 N·m) at 500 rpm, twice the 150 ft-lbf (203 N·m) of the DS-20Y in the same 22.5 in (572 mm) turning length
- 3 in (76 mm) bar capacity through a 3.5 in (88.9 mm) spindle bore, against 2.5 in (64 mm) on the DS-20Y
- Sub-spindle with a 6.5 in (165 mm) chuck, 15 hp (11.2 kW) and a 5,000 rpm top speed for back-side work
- 12-station BMT65 turret with 4,000 rpm live tools and ±2 in (±51 mm) of Y travel for off-centre drilling and milling
- Main C-axis brake holds 250 ft-lbf (339 N·m) on a 13.9 in (353 mm) disc, for milling against a clamped spindle
Limitations
- Main spindle tops out at 3,400 rpm, below the 4,000 rpm of the DS-20Y and the 4,500 rpm of the DS-30Y, which limits surface speed on small-diameter bar
- Turning length stops at 22.5 in (572 mm); the DS-30Y reaches 32.5 in (826 mm) for longer shafts
- The sub-spindle has 100 ft-lbf (135.6 N·m) and a 6.5 in (165 mm) chuck, so second-operation cuts must be lighter than those on the 10 in (254 mm) main chuck
- Y-axis thrust is 2,300 lbf (10,231 N), under half the 5,100 lbf (22,686 N) available in Z, and Y travel is only ±2 in (±51 mm)
