About this machine

This Haas ST-20 Y is a used lathe — sometimes referred to as a turning centre — dating from 2023 and currently located in Germany. Lathes of this type are used to machine workpieces by rotating them against cutting tools to produce cylindrical, conical, and profiled forms, and are central to precision component manufacturing across industries such as automotive, aerospace, energy, and general engineering. Haas Automation is a widely recognised American machine tool builder known for its CNC turning and milling equipment, and its controls and machines are found throughout production and job-shop environments worldwide.

This machine is equipped with a C-axis and a Y-axis offering ±50.8 mm of travel, giving it full multi-axis turning capability with driven live tooling at all positions of the BMT65 turret. The turret itself is a 12-position unit, and all stations are driven, meaning the machine can perform milling, drilling, and off-centre operations in a single setup without re-fixturing. Maximum turning diameter is 298 mm, maximum turning length is 572 mm, and swing over the support is 533 mm.

The spindle is an A2-6 taper unit driven by a vector-drive system, delivering a maximum power of 14.9 kW, a maximum torque of 203 Nm, and a top speed of 4,000 rpm. The spindle bore is 63.5 mm. Driven tools reach the same maximum speed of 4,000 rpm. Rapid traverse rates are 24.0 m/min on the X and Z axes and 12.7 m/min on the Y-axis. The machine includes an automatic hydraulic 3-jaw chuck with a 210 mm diameter.

Supporting equipment includes a tailstock, a tool probe for automated tool-length measurement, direct threading capability, and a coolant tank with a capacity of 208 litres complete with pump. Axis guideways are linear roller type with pre-tension, and lubrication is handled by a central automatic system — grease for the axes and oil for the spindle. Electrical supply is 3 × 400 V / 50 Hz at 14 kVA.

The Haas control features a 15-inch colour LCD monitor, an electronic handwheel on the control panel, 1 GB of operating memory, and USB and Ethernet communication interfaces. The working area is illuminated. Additional items included with the machine are a set of tool holders (compatible with BOT or hybrid turrets), a hand gun for air cleaning, and a set of levelling feet. The machine is described as being in very good condition and is available under power for demonstration.
