SUNWAY VMC-855 VERTICAL MACHINING CENTER

Technical Description

The SUNWAY VMC-855 Vertical Machining Center is a high-performance CNC machine designed for precision and efficiency in demanding machining environments. Featuring a robust hard rail structure with reinforced linear guideways, it delivers exceptional load-bearing capacity, vibration resistance, and long-term accuracy for heavy cutting operations. The machine offers a generous worktable size of 41.34 inches in length and 20.47 inches in width, supporting a maximum table load of 700 kg, making it suitable for a wide range of workpieces. The triaxial travel is 33.46 inches (X), 21.65 inches (Y), and 23.62 inches (Z), providing ample machining range for complex parts. The spindle system utilizes a BT40 taper with a maximum speed of 8,000 rpm and a spindle motor power of 11/15 kW, ensuring high-speed and high-torque performance for efficient material removal. The VMC-855 is equipped with a precision ball screw feed system, delivering rapid axis speeds of up to 16 m/min and a maximum cutting feed speed of 7 m/min. An automatic tool changer with a 24-tool capacity and an average tool change time of 2.5 seconds enhances productivity. The machine achieves a positioning accuracy of 0.008 mm and a repeat positioning accuracy of 0.005 mm, guaranteeing consistent, high-precision results. With an overall machine weight of 5,500 kg and dimensions of 2,700 x 2,300 x 2,600 mm, the VMC-855 is built for stability and durability in industrial applications.
