Horizontal turning machine SB-35LY

CNC3-axisinclined bed

Overview
The Haas SB-35LY is the long-bed version of the SB-35: a Y-axis CNC box-way lathe delivering high dynamic stiffness, strong load capacity and effective vibration damping for heavy turning applications. It combines traditional box-way construction with Haas control and service network support. Standard capacities include a 12 in (305 mm) chuck, A2-8 spindle nose and 3.5 in (90 mm) bar capacity.

Key Features

• BMT65 turret with 12 stations (supports live tooling)
• Hardened, precision ground box ways
• Hand-scraped Turcite-B slideways
• 30° slant-bed with 30° Y-axis wedge angle for rigid cutting
• Programmable steady rest provision

Important Notes

• NOTE: The SB-35LY is not compatible with the Haas Bar Feeder and is not available with a parts catcher.
• ATTENTION: The steady rest provision is not removable; this limits the minimum distance between centers. Refer to the machine layout drawing for details.
