STARRAG STC 1000 X VERTICAL MACHINING CENTER

Technical Description

This high-performance CNC spindle unit delivers 161 kW of power and operates at speeds up to 30,000 RPM, making it suitable for demanding precision machining applications. It features an HSK-A 63/80 taper interface, ensuring secure tool holding and high rigidity for optimal accuracy and repeatability. The HSK-A 63/80 taper complies with DIN 69893 standards, providing compatibility with a wide range of tooling systems and supporting both automatic and manual tool changes. The unit is designed for integration into advanced CNC machining centers, offering precise control and dynamic responsiveness for complex milling and high-speed cutting operations. Its robust construction supports heavy-duty use, with a core tensile strength of at least 800 N/mm² and a surface roughness (Ra) below 0.4 µm for reliable performance and extended tool life. The spindle’s compact design measures 374 inches in length, 307 inches in width, and 179 inches in height, and it weighs 92,594 lbs, reflecting its industrial-grade build and stability. The unit is engineered for minimal runout and maximum rigidity, ensuring consistent accuracy even under high-load conditions. The HSK-A 63/80 taper interface is compatible with shrink fit, hydraulic expansion, and ER40 tool holders, allowing for versatile tooling options. This spindle is ideal for applications requiring high torque, rapid acceleration, and precise control, such as aerospace, automotive, and mold manufacturing.
