HAAS ST-15 CNC turning center

HAAS ST-15 CNC turning center manufactured in the USA in 2019, is used for precision machining of metal workpieces with a maximum diameter of 173 mm. Thanks to its small size and emphasis on high productivity, rigidity and thermal stability, the ST-15-NGC CNC lathe is ideal for both small workshops and intensive production work.

The machine comes with modern technology and extensive equipment, allowing it to exploit all its strengths for extremely precise turning of workpieces. Inside the illuminated work area there is, among others, a hydraulic three-jaw chuck, a twelve-position VDI40 tool magazine and a very efficient spindle rotating with a maximum speed of 4000 rpm.

The HAAS ST 15 turning centre is offered with extensive additional equipment, including a tailstock with hydraulic quill extension, an automatic tool probe and a state-of-the-art HAAS NGC CNC controller located on the arm. The machine is new and has never been used – it has not worked a single hour. The total weight of the lathe is 3584 kg.
