STARRAG STC 1250 MT VERTICAL MACHINING CENTER

The STARRAG STC 1250 MT is a high-performance 5-axis vertical machining center engineered for precision and heavy-duty machining applications, particularly in aerospace and power generation. It features a robust 120 kW motor spindle capable of reaching 30,000 RPM with an HSK-A63/80 taper interface, ensuring excellent tool holding and high-speed machining capabilities. The machine’s thermo-symmetrical, closed welded design optimizes stability and minimizes vibration, enhancing accuracy and repeatability. The large travel dimensions—X: 2,200 mm (86.6"), Y: 1,500 mm (59"), Z: 2,100 mm (82.7")—accommodate sizable workpieces, while the total footprint measures approximately 11,400 mm long by 8,300 mm wide by 5,450 mm high. Weighing 58 tons, the STC 1250 MT supports heavy structural parts machining with high acceleration and short positioning times thanks to its thermally stable and dynamically optimized construction. It incorporates a CNC control system with advanced look-ahead and dynamic preselection for excellent contour fidelity during high-speed operations. The machine also includes features such as absolute optical linear and rotary axis measurement, hydraulic clamping on the MT version, and vector-controlled motor spindles with internal coolant supply and vibration monitoring. Designed to handle tough materials like titanium and Inconel, the STC 1250 MT delivers high torque and power reserve, making it ideal for heavy chip removal and complex 5-axis multi-blade machining. This combination of rigidity, thermal stability, and advanced control technology positions the STARRAG STC 1250 MT as a benchmark in precision 5-axis machining centers.
