The Hitachi Seiki HG-630 is a precision horizontal machining center designed for demanding manufacturing applications. This CNC machine features a robust construction with dimensions approximately 3200mm in length, 5831.8mm in width, and 3160mm in height, weighing around 15,237 kilograms. The machine is equipped with a FANUC 15M or 16M CNC control system, providing reliable automation for complex machining operations. The work envelope offers X-axis travel of 950mm, Y-axis travel of 800-820mm, and Z-axis travel of 762-850mm, accommodating a maximum part weight of 1,197.8 kilograms on the 630mm x 630mm table. The spindle operates at speeds ranging from 20 to 6,000 RPM with stepless control, powered by an 18.6-kilowatt motor featuring a CAT-50 spindle taper. The machine includes an automatic tool changer with either 40, 60, or 120 tool positions depending on the variant, capable of handling tools up to 20 kilograms in weight and 400mm in length. Feed rates deliver rapid traverse capabilities of up to 24 meters per minute, with cutting feed rates between 1-24 meters per minute. The horizontal configuration provides excellent accessibility for workpiece loading and unloading. A rotary shuttle pallet system with typically two 25-inch square pallets enables efficient part changeover with one-degree indexing precision. The machine incorporates through-spindle coolant delivery at pressures up to 1,000 PSI, chip conveyor systems, and full enclosure protection. This versatile machining center excels in precision engineering applications requiring high throughput and dimensional accuracy.
