Same bed and Y axis, larger spindle. The ST-15LY has an 8.3 in (210 mm) chuck, 2.5 in (64 mm) of bar capacity, 20 hp (14.9 kW) and 4,000 rpm. The ST-10LY has a 6.5 in (165 mm) chuck, 1.75 in (44 mm) of bar capacity, 15 hp (11.2 kW) and 6,000 rpm. Both have 32.5 in (826 mm) of Z, ± 2 in (± 51 mm) of Y and an 11 in (279 mm) maximum turning diameter.
Interpolated motion and positioning, 0.01° positioning, 60 rpm maximum speed and a 5 hp (3.7 kW) maximum rating. The brake is 13.9 in (353 mm) in diameter with 250 ft-lbf (339 N·m) of holding torque.
Y travel is ± 2 in (± 51 mm). The Y axis rapids at 472 ipm (12 m/min) and is rated for 2,300 lbf (10,231 N) of thrust. Since bar capacity is 2.5 in (64 mm), the Y stroke spans the full width of any bar the spindle can pass.
An MT3 tailstock with 3.8 in (95 mm) of hydraulic quill travel, 44 in (1,118 mm) of manual body positioning and quill thrust adjustable between 140 lbf (623 N) and 1,130 lbf (5,026 N).
220 VAC three-phase at 40 A or 440 VAC three-phase at 20 A. It also needs 4 scfm of air at 100 psi (113 L/min at 6.9 bar). The machine ships at 10,000 lb (4,536 kg) on a 158 × 70 × 81 in (401 × 178 × 206 cm) pallet, and the coolant tank holds 30 gal (114 L).
