Haas Automation publishes a list price of US$178,995 for the Haas ST-30LY (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-30ly#price; the request is passed to Haas Automation or an authorised dealer.
Maximum turning length and the distance between centers are 62.5 in (1,588 mm). Maximum turning diameter is 13.75 in (349 mm) under a 21 in (533 mm) swing, with 9.4 in (239 mm) of X travel. The chuck is 10 in (254 mm) and bar capacity is 3 in (76 mm).
A programmable tailstock with a #4 Morse taper is listed as standard. A steady rest provision, which Haas describes as being for part-face machining or supporting extra-long parts, is an option. Automatic doors are also listed as an available option for easier part loading.
Y travel is ± 2 in (± 51 mm), with a 472 ipm (12 m/min) rapid and 2,300 lbf (10,231 N) of thrust. The C axis has a maximum speed of 60 rpm, a 5 hp (3.7 kW) maximum rating and 0.01° positioning, and its 13.9 in (353 mm) brake holds 250 ft-lbf (339 N·m). The table has no live-tool speed row for this model.
The ST-28LY has a 12 in (305 mm) chuck, 4 in (102 mm) of bar capacity, 40 hp (29.8 kW) and 425 ft-lbf (576 N·m) at 325 rpm, with 42.5 in (1,080 mm) of Z and an 11.75 in (298 mm) turning diameter. The ST-30LY has a 10 in (254 mm) chuck, 3 in (76 mm) of bar capacity and 30 hp (22.4 kW), with 62.5 in (1,588 mm) of Z and a 13.75 in (349 mm) turning diameter.
Yes, as an option. The standard spindle gives 300 ft-lbf (407 N·m) at 500 rpm. With the optional gearbox the table lists 1,000 ft-lbf (1,356 N·m) at 150 rpm, which is the figure to look at for heavy cuts on large-diameter steel.
