About this machine

This Haas ST-25Y is a used lathe — sometimes referred to as a turning centre — dating from 2020 and currently located in the United Kingdom. Lathes are machine tools used to rotate a workpiece against a cutting tool to perform operations such as turning, facing, boring, and threading, and are fundamental across precision engineering, aerospace, automotive, and general subcontract manufacturing. Haas Automation is one of the most widely recognised machine tool builders in the world, producing CNC lathes, machining centres, and rotary tables used extensively in production and job-shop environments globally.

This particular machine is equipped with a Y-axis, which extends the capabilities of a standard turning centre by allowing off-centre milling and drilling operations without repositioning the workpiece, effectively combining turning and milling functionality in a single setup. The Y-axis travel on this machine is ±50.8 mm, providing meaningful off-centreline reach for complex part geometries.

The spindle accepts bar stock up to 76 mm in diameter and reaches a maximum speed of 3,400 rpm, driven by a 22.4 kW spindle motor. Workholding is via a 254 mm three-jaw chuck. The principal capacity figures are a maximum machining diameter of 298 mm, a swing of 533 mm, and a cutting length of 572 mm, giving a solid working envelope for medium-sized turned components.

Tooling is managed through a 12-station turret, allowing a substantial number of tools to be held ready in a single setup and reducing changeover time during complex operations. A tool setter is included, enabling automatic tool length measurement and offset setting directly at the machine.

Ancillary equipment fitted to this machine includes a swarf conveyor for continuous chip removal, a coolant system, and a tailstock for supporting longer workpieces during machining. The machine runs on the Haas control system, Haas's own proprietary CNC interface widely regarded for its straightforward operation and broad industry familiarity.
