Haas Automation publishes a list price of US$143,995 for the Haas SB-28Y (verified 2026-10-02). Options, tooling, freight and installation are extra, so a dealer quote will differ. A specific price can be requested at https://machinetoolindex.com/machines/haas-sb-28y#price; the request is passed to Haas Automation or an authorised dealer.
Y travel is ±2 in (±50 mm), with 4,490 lbf (19,972 N) of thrust and a 283 ipm (7.2 m/min) rapid. Together with BMT65 live tooling at 4,000 rpm and a C axis that positions to 0.01°, it lets flats, keyways and off-centre holes be machined in the turning setup instead of on a mill.
The SB-28 has no Y axis and a larger turning envelope: 13.5 in (345 mm) in diameter and 21.3 in (540 mm) in length, with 9 in (230 mm) of X, 23.2 in (590 mm) of Z and a 630 ipm (16 m/min) X rapid, at a shipping weight of 12,600 lb (5,715.4 kg). The SB-28Y turns 12 in (305 mm) by 18.5 in (470 mm) and ships at 13,960 lb (6,332.3 kg). Chuck, bar capacity, spindle and bore are the same.
The base spindle is rated 40 hp (29.8 kW) with 425 ft-lbf (576 N·m) at 325 rpm and a 3,200 rpm top speed. Haas lists an optional gearbox that raises torque to 1,400 ft-lbf (1,898 N·m) at 150 rpm. The spindle bore is 3.39 in (86 mm) and the draw tube bore 2.95 in (75 mm).
The SB-35Y is the larger-bore machine: a 12 in (305 mm) chuck, 3.5 in (90 mm) of bar capacity, a 4.13 in (105 mm) spindle bore and 27.5 in (700 mm) of turning length, with a 2,500 rpm spindle. The SB-28Y has a 10 in (254 mm) chuck, 2.9 in (74 mm) of bar capacity, 18.5 in (470 mm) of turning length and 3,200 rpm. Maximum turning diameter is 12 in (305 mm) on both.
Power is 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. Air is 4 scfm at 100 psi (113 L/min at 6.9 bar), with an 80 psi (5.5 bar) minimum. Coolant capacity is 40 gal (151 L). Shipping weight is 13,960 lb (6,332.3 kg) on a 179 × 90 × 98 in (455 × 229 × 249 cm) pallet, which is the shipping size and not the installed size.
