MITSUI SEIKI VX550-5X VERTICAL MACHINING CENTER

Technical Description

The Mitsui Seiki VX550-5X is a high-precision, 5-axis vertical machining center engineered for demanding aerospace, die/mold, and complex component manufacturing. It features robust linear axis travels of 21.7 inches (X), 23.6 inches (Y), and 17.7 inches (Z), providing ample workspace for intricate multi-sided machining. The machine is equipped with a trunnion-style rotary table, enabling full 5-axis simultaneous operations for superior geometric accuracy and surface finish. Its control system is powered by the advanced FANUC 31i CNC, renowned for its reliability, intuitive interface, and support for high-speed, high-accuracy machining. The VX550-5X delivers rapid traverse rates up to 1,900 inches per minute on linear axes, ensuring efficient cycle times. The spindle offers high-speed capability, typically up to 25,000 RPM with an HSK-A63 taper, and is paired with a 40-pocket automatic tool changer for seamless tool management. The machine’s rigid construction and precision feedback systems—including linear scales on X, Y, and Z axes and absolute rotary encoders on the A and C axes—ensure exceptional repeatability and positioning accuracy. Designed for heavy-duty production, the VX550-5X supports high table loads and integrates seamlessly with automation systems. Its compact footprint and comprehensive feature set make it ideal for shops requiring maximum flexibility, throughput, and part quality in a 5-axis platform.
