ST25 series machine with numerical program control can carry out complex machining by means of various tools. The turning center can be equipped with 12-position turret, and all 12 positions can be used for the driving tool simultaneously that significantly expands technological capabilities and increases labor productivity.

45-degree slant bed provides the sufficient strength and rigidity at the extreme loadings because of high-performance processing. The guideways carry high loads. Strength margin allows the ball screw works both in the high speeds, and in the mode of power turning.

The bed is cast from high-strength cast iron in Penza city. It naturally and artificially aged, has additional strengthening ribs and specially developed construction. Machining and hardening of guideways are made by the “StankoMashStroy” company.

CNC turning center ST25LM is equipped with BMT65 turret made by South Korea and holders made by WTO company. Drive power is 2.2/3.7 kW standard or 3.7/5.5 kW optional. The main advantage of turret is the possibility to install all 12-drive holders simultaneously, turned the lathe into the milling center. The turret indexing accuracy is ±0,003 mm.

Machining and assembly is made in the temperature-controlled rooms, equipped with precision SKF bearings. It has high output capability and high vibration strength that allows to machine alloy-treated steel and special alloy with 7 accuracy degree and degree of roughness 0.8 under Ra criterion.
