Haas ST-40Y Lathe

SKU: ST-40Y
Haas ST-40Y – Large Lathe with Y-Axis and Milling Capabilities The Haas ST-40Y is an enhanced version of the popular ST-40 model, enhanced with Y-axis movement. This gives the turning center the ability to perform additional milling, drilling, and tapping operations—all in a single workpiece setup. The combination of a Y axis, a fully interpolated C axis, and driven tools significantly reduces machining time and increases production flexibility. The machine offers a large work envelope, robust construction, and excellent value for money in its class. Key features: 12-station BMT75 tool head, Spindle nose A2-8 – possibility of processing bars up to Ø 102 mm, Y-axis movement: ±76 mm (±3.0"), Fully interpolated C-axis for precise positioning, Milling, drilling and threading without the need for additional setup. The Haas ST-40Y is a versatile solution for shops looking to combine turning and milling operations in one machine, increasing productivity and lowering production costs.
