HAAS ST-20 CNC turning center

HAAS ST-20 CNC turning center was built in 2011 in the United States by HAAS AUTOMATION, INC. The machine is designed for the production of precision parts used in various industries. It enables the efficient turning of workpieces with a maximum diameter of 381 mm and a length of 533 mm.

Machining is performed using a spindle with a maximum rotational speed of 4000 rpm. The HAAS ST-20 works in two axes, X and Z, with feeds of 236 mm and 533 mm respectively. The 12-position turret allows for the use of different tools during machining and enables their rapid exchange. All this is complemented by a compact, highly rigid design.

The ST-20 CNC lathe is operated using an intuitive HAAS CNC controller with access to numerous advanced functions. The machine is also equipped with a measuring probe and a chip conveyor designed to automatically remove chips from the work area. The total weight of the machine is approximately 3900 kg.
