Haas Automation publishes a list price of US$108,995 for the Haas ST-15Y (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-st-15y#price; the request is passed to Haas Automation or an authorised dealer.
Spindle size. The ST-15Y has an 8.3 in (210 mm) chuck, an A2-6 nose, 2.5 in (64 mm) of bar capacity, 20 hp (14.9 kW) and 150 ft-lbf (203 N·m) at 500 rpm, with a 4,000 rpm limit. The ST-10Y has a 6.5 in (165 mm) chuck, an A2-5 nose, 1.75 in (44 mm) of bar capacity, 15 hp (11.2 kW) and 75 ft-lbf (102 N·m) at 1,300 rpm, with a 6,000 rpm limit. Travels and Y axis are the same.
Yes in terms of travel. Y travel is ± 2 in (± 51 mm) and the largest bar is 2.5 in (64 mm), so the live tool can reach either edge of the bar. Live tools are BMT45 and run to 4,000 rpm; Y thrust is 2,300 lbf (10,231 N).
The table gives a 5.3 in (135 mm) sub-spindle chuck with a throat 1.3 in (33 mm) in diameter and 1.37 in (34.8 mm) deep, a drawbar bore of 1 in (25.4 mm) by 4.5 in (114.3 mm) deep and a 1.5 in (38.1 mm) spindle bore. Whether the sub-spindle is on the machine you are quoted is a question for Haas.
The brake is 13.9 in (353 mm) in diameter and holds 250 ft-lbf (339 N·m). The C axis itself positions to 0.01°, runs at up to 60 rpm and has a maximum rating of 5 hp (3.7 kW), with interpolated motion and positioning.
Three-phase power, 40 A at 220 VAC or 20 A at 440 VAC, and 4 scfm of air at 100 psi (113 L/min at 6.9 bar). Coolant capacity is 30 gal (114 L). Shipping weight is 7,900 lb (3,583 kg).
