MITSUI SEIKI HU63A HORIZONTAL MACHINING CENTER

Technical Description

The Mitsui Seiki HU63A Horizontal Machining Center features a robust 24.8" x 24.8" (L x W) table capable of supporting workpieces up to 2,700 lbs. It includes an optional indexed or rotary support table and can be equipped with up to a 4-axis configuration, although standard operation is with 3 axes (X, Y, Z). Axis travels measure 35.43" (X), 31.5" (Y), and 31.5" (Z), each with a max feed rate of 394 ipm and rapid traverse speed of 1,260 ipm. The horizontal spindle employs a #50 taper with a standard top speed of 6,000 RPM, upgradeable to 12,000 RPM, and is powered by a 25 HP (30 HP optional) motor, supporting high-power heavy machining. The machine features an automatic tool changer (ATC) with a 60-tool capacity, expandable to 180 tools, and a rapid 2-second tool change time without chip-to-chip delay. Pallet changers are optional, with standard 2 pallets and an option for up to 10, facilitating efficient production runs and workpiece exchange. This combination of powerful spindle, substantial travel, rapid feedrates, and flexible tooling and pallet management makes the HU63A well-suited for heavy-duty, precision horizontal machining tasks demanding high throughput and versatility.
