STARRAG LX 021 VERTICAL MACHINING CENTER

Technical Description

The STARRAG LX 021 is a high-precision 5-axis vertical machining center optimized for turbine blade manufacturing, featuring compact dimensions with X, Y, and Z axis travels of 15.7" (399 mm), 7.9" (201 mm), and 16.1" (409 mm) respectively. It is powered by a 20 kW spindle capable of speeds up to 30,000 RPM, utilizing an HSK-A40 taper for tool retention. The machine supports a robust 320-station automatic tool changer, enabling high production flexibility and efficiency. Equipped with a Siemens 840D CNC control, it ensures precise machining with linear axis positioning accuracy of 0.004 mm and rotary axis precision suitable for complex blade geometries. Its thermo-symmetrical cast design offers outstanding stability and low vibration, critical for maintaining surface integrity and dimensional accuracy during the machining of superalloy turbine blades. The LX 021 incorporates advanced CAM integration and adaptive milling routines for process reliability and efficiency in both prototype and series production. Its 5-axis configuration includes full 360° A-axis rotation and -45°/+95° swivel on the B-axis, allowing complete multi-surface machining in a single clamping setup, minimizing distortion and setup time. The machine is designed for the aerospace industry, capable of handling blades up to approximately 200 mm in size and is supported by comprehensive process monitoring and inspection systems. Overall, the LX 021 provides a turnkey solution for highly accurate, automated turbine blade machining with optimized throughput and quality control.
