Overview
The Haas SB-35LY is the long-bed, Y-axis member of Haas's box-way lathe series: a 12 in (305 mm) chuck, 3.5 in (90 mm) of bar capacity, 49.8 in (1,265 mm) of Z travel and a turret that moves ± 2 in (± 50 mm) in Y with BMT65 live tools turning at 4,000 rpm. Maximum turning length is 47.3 in (1,200 mm) on a 12 in (305 mm) maximum turning diameter, so this is a machine for shafts that also need flats, keyways or cross holes.
The bed is what separates it from the SB-35Y, which has the same chuck, spindle and Y travel but stops at 27.5 in (700 mm) of turning length and 30.1 in (765 mm) of Z. Here the table lists a tailstock with 39.4 in (1,000 mm) of travel and a hydraulic quill with 4.7 in (120 mm) of stroke on an MT5 taper, and the distance between centres is 58.8 in (1,493 mm). A part at full turning length is roughly four times as long as the largest diameter the turret can cut, which is work that has to run on a centre.
The spindle is built for torque, not speed. It is rated 40 hp (29.8 kW) with 425 ft-lbf (576 N·m) at 325 rpm and a 2,500 rpm ceiling, on an A2-8 nose with a 4.13 in (105 mm) bore and a 3.58 in (91 mm) draw tube. The table also gives a figure for an optional gearbox: 1,400 ft-lbf (1,898 N·m) at 150 rpm, about 3.3 times the base torque. That is an extra, so look for it on the quote if low-speed roughing matters.
The Y axis is slower and lighter than the turning axes. It rapids at 283 ipm (7.2 m/min) against 472 ipm (12 m/min) on X and 787 ipm (20 m/min) on Z, and its thrust is 4,490 lbf (19,972 N) where X and Z are each rated 7,780 lbf (34,607 N). The C axis interpolates and positions to 0.01°, runs at up to 60 rpm on a 5 hp (3.7 kW) rating, and is held by a 13.9 in (353 mm) brake with 250 ft-lbf (339 N·m) of holding torque. Heavy milling against the clamped spindle is limited by that brake figure, not by the 40 hp motor.
Adding Y takes some turning envelope: the SB-35 without Y turns 13.5 in (345 mm) in diameter with 9 in (230 mm) of X travel, against 12 in and 8.1 in (206 mm) here. The machine ships on a 214.5 × 90.5 × 99 in (545 × 230 × 252 cm) pallet, holds 100 gal (379 L) of coolant, and Haas lists a starting price of US$217,995.

Strengths & Limitations
Strengths
- 49.8 in (1,265 mm) of Z travel and 47.3 in (1,200 mm) of turning length, with 39.4 in (1,000 mm) of tailstock travel to support the part
- ± 2 in (± 50 mm) of Y travel with BMT65 live tooling at 4,000 rpm for off-centre milling and drilling on long shafts
- 40 hp (29.8 kW) spindle with 425 ft-lbf (576 N·m) at 325 rpm; an optional gearbox is listed at 1,400 ft-lbf (1,898 N·m) at 150 rpm
- 3.5 in (90 mm) bar capacity through a 4.13 in (105 mm) spindle bore on an A2-8 nose
- C axis with interpolated motion, 0.01° positioning and a 13.9 in (353 mm) brake holding 250 ft-lbf (339 N·m)
- 7,780 lbf (34,607 N) of thrust on both X and Z
Limitations
- Spindle speed tops out at 2,500 rpm, which limits surface speed on small-diameter work
- Maximum turning diameter is 12 in (305 mm) and X travel 8.1 in (206 mm), less than the 13.5 in (345 mm) and 9 in (230 mm) of the SB-35 without Y
- Y rapid is 283 ipm (7.2 m/min) and Y thrust 4,490 lbf (19,972 N), both well below the X and Z figures
- The 1,400 ft-lbf (1,898 N·m) torque figure belongs to an optional gearbox, not the base machine
- Ships on a pallet 214.5 in (545 cm) long and the table gives no machine weight, so get rigging figures from Haas before delivery

Frequently Asked Questions
01
Bed length. The SB-35Y has 30.1 in (765 mm) of Z travel and 27.5 in (700 mm) of turning length; the SB-35LY has 49.8 in (1,265 mm) and 47.3 in (1,200 mm). Chuck size, bar capacity, the 40 hp (29.8 kW) 2,500 rpm spindle, X travel and Y travel are the same on both.
02
± 2 in (± 50 mm). The Y axis rapids at 283 ipm (7.2 m/min) and is rated for 4,490 lbf (19,972 N) of thrust. Live tooling is BMT65 and runs at up to 4,000 rpm, and the C axis positions to 0.01° with interpolated motion.
03
Torque at low speed. The base figure is 425 ft-lbf (576 N·m) at 325 rpm. With the optional gearbox the table gives 1,400 ft-lbf (1,898 N·m) at 150 rpm, about 3.3 times as much. The table gives one power figure, 40 hp (29.8 kW), and one top speed, 2,500 rpm.
04
The table lists a tailstock with an MT5 taper, 39.4 in (1,000 mm) of travel and a hydraulic quill that strokes 4.7 in (120 mm). Distance between centres is 58.8 in (1,493 mm) and maximum turning length is 47.3 in (1,200 mm). No steady rest appears in the table.
05
Either 220 VAC three-phase at 70 A or 440 VAC three-phase at 35 A. Air consumption is 4 scfm at 100 psi (113 L/min at 6.9 bar) with a minimum supply pressure of 80 psi (5.5 bar), through a 3/8 in hose and coupler. The coolant tank holds 100 gal (379 L).
