YITONG VMC-850L VERTICAL MACHINING CENTER

Technical Description

The YITONG VMC-850L is a CNC Vertical Machining Center designed for medium-duty milling, drilling, tapping, and boring operations. It features a 31.5-inch (800 mm) X-axis travel, with 19.7 inches (500 mm) travel on both Y and Z axes, providing a versatile working envelope. The machine is equipped with a BT40 spindle taper and a high-speed spindle capable of reaching up to 8,000 RPM, driven by a 7.5 kW motor, combining power and precision for a variety of machining applications. The worktable measures approximately 39.4 inches in length and 19.7 inches in width, supporting workpieces up to 500 kg, with T-slots configured for secure fixturing. This VMC model comes with linear guideways on all three axes for enhanced rigidity and smooth motion, ensuring high positional accuracy typically within ±0.005 mm and repeatability close to ±0.002–0.003 mm. The control system is CNC-based, and common options include FANUC, Siemens, or GSK, providing flexible and reliable machine control. The machine also supports a 24-tool automatic tool changer for efficient tool management and reduced downtime. Its robust Meehanite casting frame combined with precise ball screw drives ensures long-term stability and machining accuracy. The rapid feed rates on axes peak around 24 m/min, optimizing productivity. Overall, the YITONG VMC-850L offers a blend of precision, rigidity, and operational efficiency suited for mold making, automotive parts, and general precision machining tasks.
