YASDA H40I HORIZONTAL MACHINING CENTER

Technical Description

The Yasda H40i is a high-precision 5-axis horizontal machining center engineered for complex, high-mix, and low-volume production. It features a rigid machine structure with ribbed cast iron construction and roller-type guideways with retainers on the X, Y, and Z axes, ensuring vibration damping and static accuracy. The machine offers generous travels of 34.45" (X), 29.13" (Y), and 26.97" (Z) with a 15.75" x 15.75" table supporting up to 440 lbs workpiece weight. The 40-taper Big Plus spindle is direct drive type with a 20,000 rpm top speed and 29 HP (30-minute rating) to accommodate high-speed, precision cutting on various material types. The spindle is designed for minimal thermal distortion to maintain optimal tool performance and fine surface finishes. This machine includes 5 axes: linear X-Y-Z and rotary A (360°) and B (230°) axes, both powered by high-speed direct drive motors enabling simultaneous 5-axis machining with rapid traverse rates up to 1,965 ipm on linear axes. The tool system features an automatic tool changer (ATC) with a standard 60-tool magazine, expandable up to 120 tools, with a tool change chip time of 4 seconds. A pallet changer with two pallets is standard, enabling efficient job setup and reduced downtime. Control is typically via FANUC 31i series CNC, complemented by optical scale feedback for precise positioning. Overall, the Yasda H40i is designed to maximize machining flexibility, throughput, and precision within a compact footprint suitable for aerospace, die/mold, and automotive applications.
