STARRAG STC 1250 VERTICAL MACHINING CENTER

Technical Description

The STARRAG STC 1250 Vertical Machining Center is a robust 5-axis CNC machine engineered for high-performance milling of complex structural parts, multi-blades, and casings, especially in aerospace and power generation sectors. It features a powerful 93.9 HP spindle delivering up to 15,000 RPM with an HSK-A100 taper, optimized for heavy chip removal on tough materials such as titanium and Inconel. The machine’s construction incorporates a thermo-symmetrical design with closed welded elements, ensuring exceptional stability, minimal vibration, and high positional accuracy. Its large working envelope spans 86.6" (X) by 59" (Y) by 82.7" (Z), accommodating sizeable workpieces while maintaining precision. The machine’s dimensions are 449"L x 327"W x 215"H, and it weighs approximately 127,867 lbs, reflecting its solid and durable build. Advanced features include a tried and tested rotatable head, high acceleration for reduced positioning times, and dynamic path control that ensures contour fidelity at high speeds. The spindle is equipped with water-cooling and direct oil-air lubrication, along with sensors for bearing temperature and vibration monitoring, enhancing operational reliability and longevity. An absolute optical measurement system covers all five linear and rotary axes, guaranteeing repeatability and precision in complex machining tasks. The STC 1250 is designed with options like variable hydraulic bearing pretensioning, integrated coolant supply, and recoil protection to meet diverse application requirements. Its control system is optimized for roughing to super finishing processes, balancing accuracy, surface quality, and productivity. This machining center is a benchmark for heavy-duty, high-precision parts manufacturing with innovative solutions for advanced industrial applications.
