Haas Automation publishes a list price of US$202,995 for the Haas ST-35LY (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-35ly#price; the request is passed to Haas Automation or an authorised dealer.
± 2 in (± 51 mm), with 2,300 lbf (10,231 N) of thrust and a 472 ipm (12 m/min) rapid. That stroke covers flats, keyways and off-centre holes close to the spindle axis. Features further from the centreline on a part near the 13.75 in (349 mm) turning diameter are reached by rotating the C axis.
The C axis runs at up to 60 rpm with a maximum rating of 5 hp (3.7 kW) and positions to 0.01°. Its brake is 13.9 in (353 mm) in diameter and has 250 ft-lbf (339 N·m) of holding torque. That holding torque is the limit to respect when milling or drilling far from the centreline with the spindle clamped.
The ST-28LY turns 11.75 in (298 mm) in diameter and 42.5 in (1,080 mm) in length, with ± 2 in (± 51 mm) of Y travel. The ST-35LY turns 13.75 in (349 mm) and 62.5 in (1,588 mm) with the same Y travel. Chuck size, bar capacity, spindle power, torque and maximum speed are the same on both.
A programmable tailstock with a #4 Morse taper is standard. For extra-long parts, or for machining a part face, Haas offers a steady rest provision as an option. Distance between centers is 62.5 in (1,588 mm). The table lists no tailstock thrust for this model.
Electrical supply is three-phase, 70 A at 220 VAC or 35 A at 440 VAC. Air demand is 4 scfm at 100 psi (113 L/min at 6.9 bar) with at least 80 psi (5.5 bar) at the machine, through a 3/8 in hose and coupler. It ships at 13,820 lb (6,268 kg) on a 202 × 90 × 92 in (513 × 229 × 234 cm) pallet.
