The Yasda YBM Vi40 Vertical Machining Center is a high-precision, 5-axis CNC jig borer designed for demanding applications in mold, die, aerospace, medical, and automotive industries. Featuring a symmetric bridge-type structure constructed from high-grade cast iron, the machine delivers exceptional rigidity and stability for heavy cuts and ultra-accurate milling of hardened materials. The X, Y, and Z-axis travels measure 35.43 inches (900 mm), 19.68 inches (500 mm), and 17.71 inches (450 mm), respectively, providing a generous work envelope for complex components. The direct-drive spindle reaches speeds up to 24,000 RPM, ensuring precision across the entire speed range, while the BT40 taper supports versatile tooling. An automatic tool changer (ATC) with 60 tool capacity (expandable to 100 or 200 tools) streamlines production and reduces downtime. The machine is equipped with a highly accurate B/C-axis tilting rotary table, enabling 5-sided and simultaneous 5-axis machining with indexing accuracies of ±0.50 sec on the B-axis and ±0.20 sec on the C-axis. Advanced thermal distortion stabilization, including temperature-controlled oil circulation, maintains accuracy during long production runs. The FANUC 31i-B5 control system with a 15-inch color LCD and intuitive OpeNe software provides seamless operation, high-speed interpolation, and comprehensive machine management. The YBM Vi40’s design optimizes operator access, reduces tool length requirements, and supports high feed rates, making it a reliable solution for high-precision, high-efficiency machining of complex, hardened parts.
