YITONG VMC-1890B VERTICAL MACHINING CENTER

Technical Description

The YITONG VMC-1890B is a mid-range vertical machining center designed for precision manufacturing of complex parts requiring multiple operations. With a spacious work envelope of 1,800mm (X-axis), 900mm (Y-axis), and 680mm (Z-axis), this machine accommodates substantial workpieces up to 1,600kg on its 2,000mm × 900mm work table. The machine features a robust cast-iron construction with reinforced internal structure, ensuring excellent rigidity and dimensional stability during heavy-duty cutting operations. The VMC-1890B is equipped with a maximum spindle speed of 8,000 RPM and delivers 18.5-22kW of spindle motor power, providing aggressive material removal capabilities across various applications. It utilizes BT50 spindle taper configuration with rapid traverse rates of 12-20m/min on X and Y axes and 10-15m/min on the Z-axis. The machine incorporates three-axis servo motor drive systems (5.5-7.5kW per axis) with linear guide rails for smooth, accurate positioning. Standard features include a 24-tool automatic tool changer with approximately 3-second tool-to-tool time, enabling efficient unattended operation. Positioning accuracy is ±0.005mm/300mm with repeat positioning accuracy of ±0.004mm. The GSK or Mitsubishi CNC control system manages complex 3-axis linking operations seamlessly. This machining center is ideally suited for mold manufacturing, aerospace components, automotive parts, and general precision metalworking applications requiring versatility and consistent accuracy in batch production environments.
