STARRAG STC 1600 MT VERTICAL MACHINING CENTER

Technical Description

The STARRAG STC 1600 MT is a high-performance 5-axis vertical machining center engineered for precision heavy-duty cutting operations in aerospace and power generation industries. This hybrid mill-turn center combines simultaneous 5-axis milling capabilities with turning functionality, enabling complex components to be machined in a single clamping operation. The machine features working envelope dimensions of 110.24" (X-axis), 74.8" (Y-axis), and 96.46" (Z-axis), accommodating workpieces up to 8,000 kg. It delivers 49.6 hp continuous power at 8,000 RPM through a gear-driven spindle configured with ISO 50 (HSK-A100) taper, generating 940 Nm of torque—ideal for titanium and Inconel machining. The machine weighs approximately 138,600 pounds and occupies floor space of 14,500L x 10,200W x 5,450H mm. Engineered with thermo-symmetrical design, closed-welded elements, and FE optimization, the STC 1600 MT delivers exceptional rigidity and low-vibration performance critical for high-material removal rates. Its rotatable head and A-axis (±100°/+60°) enable simultaneous 5-axis cutting with positioning uncertainty of 0.006mm and reversal error of 0.002mm. The machine incorporates absolute optical measurement systems for all linear and rotary axes, internal coolant supply, and variable hydraulic bearing preload. Optional spindle configurations extend capabilities from 70 kW high-speed motor spindles (15,000-24,000 RPM) to enhanced gear spindles with 1,300 Nm torque for extreme heavy-duty applications.
