Overview

The Haas SB-35LY is the most capable machine in the SB box-way series, combining long-bed Z-axis travel, Y-axis milling, live tooling, and hardened box-way construction in a single platform. It is designed for shops that need to turn long shafts and components in tough materials while adding cross-drilling, milling, and off-center features without a second setup.

The spindle delivers 29.8 kW (40 hp) with a max speed of 2,500 RPM on an A2-8 spindle nose. Peak torque is 542 Nm (400 ft-lb) at 500 RPM, with the optional gearbox pushing 1,898 Nm (1,400 ft-lb) at 150 RPM. The 305 mm (12 in) chuck and 89 mm (3.5 in) bar capacity match the standard SB-35. Max cutting diameter is 406 mm (16 in) with a cutting length of 1,524 mm (60 in).

The BMT-65 turret provides 12 stations of live tooling at 4,000 RPM with 3.7 kW (5.0 hp). Y-axis travel of 102 mm (4.0 in) total enables milling flats, hexes, keyways, and cross-drilling on long turned components. C-axis positioning resolves to 0.01 degrees for precise angular feature placement.

The box-way advantage becomes especially apparent on long parts in tough materials. Where linear-guide machines may chatter on heavy interrupted cuts across a 60-inch bed, the SB-35LY hardened box ways absorb vibration and maintain surface finish consistency. This makes it the go-to machine for shops machining long pump shafts, hydraulic cylinders, and downhole tools with cross-holes and milled features.

At $155,000-$195,000 configured, the SB-35LY is the premium offering in the SB lineup. It competes with the Doosan Puma 3100LMY and Okuma LB4000 EX II MY-L in shops that demand the best possible rigidity on long mill-turn work.

Strengths & Limitations

Strengths

Combines box-way rigidity, long-bed Z-travel, Y-axis milling, and live tooling in one platform for maximum versatility
1,524 mm (60 in) Z-axis with box ways maintains cutting stability across the entire bed length on long parts
40 hp spindle with optional 1,400 ft-lb gearbox handles heavy roughing in stainless, Inconel, and alloy steels
BMT-65 turret with live tooling enables cross-drilling, milling, and feature work without a second setup
Box-way vibration damping produces better surface finish than linear-guide machines on long, heavy cuts
C-axis positioning to 0.01 degrees ensures accurate angular feature placement on long components

Limitations

2,500 RPM max spindle speed limits surface speed on small-diameter aluminum work
Slower rapids at 400/600 IPM compared to linear-guide ST-LY machines increase non-cutting time
At $155-195K, this is the most expensive SB-series machine and approaches ST-40Y territory
Extended bed plus Y-axis hardware creates a large footprint requiring careful floor space planning

Best For

Long-shaft mill-turn work in tough materials where box-way rigidity and 60-inch Z-travel are both required Oil and gas shops machining long downhole tools, pump shafts, and couplings with cross-holes and milled features Hydraulic cylinder manufacturers adding port holes, flats, and mounting features to long turned components Defense shops machining barrel blanks, long spindles, and extended components with off-center features Shops that need the rigidity of box ways on long parts without sacrificing mill-turn capability

Frequently Asked Questions

01 What does a new Haas SB-35LY cost?

Base price starts around $155,000 with BMT-65 turret and Y-axis. Configured with tailstock, gearbox, chip conveyor, steady rest, and high-pressure coolant, expect $175,000-$195,000. This is the most feature-rich SB-series machine Haas builds.

02 What is the difference between the SB-35LY and the ST-35LY?

Both offer long-bed Y-axis mill-turn capability. The SB-35LY uses hardened box ways for superior rigidity and vibration damping. The ST-35LY uses linear guides for faster rapids and cycle times on lighter cuts. Choose the SB-35LY for heavy cutting in tough materials; the ST-35LY for higher throughput on less demanding work.

03 Is the SB-35LY worth the premium over the SB-35L?

If you are currently running turned parts on the SB-35L and then moving them to a VMC for cross-holes, flats, or keyways, the SB-35LY eliminates that second operation. The time savings and improved accuracy from single-setup machining typically justify the $50-65K premium within months of production.

04 Can I use a steady rest with Y-axis operations?

Yes, but the steady rest must be positioned to clear the Y-axis travel envelope. Coordinate with your Haas dealer on steady rest placement relative to the milling zone. For long, slender parts with milled features at specific locations, plan the setup to support the workpiece during both turning and milling operations.
