SERI VMC-850 VERTICAL MACHINING CENTER

Technical Description

The SERI VMC-850 Vertical Machining Center is a high-performance, rigid CNC machine designed for precision milling, drilling, tapping, and boring across three axes (X: 31.5 in, Y: 19.7 in, Z: 21.7 in). It features a powerful 10 hp spindle motor capable of reaching speeds up to 8,000 RPM with a BT40 taper, enabling high-speed machining with excellent torque. The machine’s worktable measures 39.4 by 19.7 inches and supports substantial workpiece loads, optimized for mechanical processing and mold making. It employs linear guide rails and ball screws for accurate and smooth axis motion, yielding positioning accuracy typically around ±0.005 mm and repeatability within ±0.003 to ±0.0075 mm. Rapid traverse rates reach up to 24 m/min (X/Y) and 20 m/min (Z), maximizing throughput. Its 3-axis CNC control system provides precise command over machining operations, with options for tool changers (typically 20-24 tools capacity) enhancing automation. The machine body is constructed from thermally stable cast iron with a robust column and base to reduce vibration and improve dynamic performance for superior surface finish and dimensional stability. Additional features often include automatic lubrication systems, coolant through spindle options, and chip conveyors, supporting extended heavy-duty operation. Overall, the VMC-850 balances high rigidity, accuracy, and productivity, making it suitable for both rough and finish machining tasks in various production environments. Machine dimensions run about 2600 x 2300 x 2800 mm with a weight near 5,000-5,700 kg depending on configuration.
