SHIBAURA MACHINE CO. MPC-3680B HORIZONTAL MACHINING CENTER

Technical Description

The Shibaura Machine Co. MPC-3680B is a heavy-duty horizontal machining center designed for large-scale and precision machining operations. It features a robust double-column structure supporting a large table measuring 122.4 inches wide by 314.9 inches long, capable of handling workpieces up to 88,000 pounds. The spindle is horizontal with a 50 taper, delivering up to 3,000 RPM and 40 HP (30-minute rating) for powerful cutting performance. The machine is equipped with a 60-tool automatic tool changer (ATC) for efficient machining with minimal downtime. The pallet changer system is optional, supporting up to 2 pallets, enabling versatile workpiece handling and setup. This machining center operates on 4 axes (X, Y, Z, and a secondary axis), with travels of 295.0 inches (X), 144.0 inches (Y), and 35.4 inches (Z). It supports rapid traverse rates of 787 inches per minute (ipm) across all axes, with a maximum feed rate of 236 ipm, combining large work envelope capacity with fast movements for productivity. The machine lacks a U axis but compensates with its large working volume and rigidity, suitable for heavy cutting typical in energy, aerospace, and automotive industrial applications. Overall, the MPC-3680B is engineered for high precision, durability, and efficient handling of large, heavy parts in demanding manufacturing environments.
