The MITSUI SEIKI HR6A is a horizontal CNC machining center manufactured in 1984 by MITSUI SEIKI KOGYO CO., LTD. in Japan. This machine is designed for mass production environments, offering precision and efficiency in milling, threading, and boring large workpieces. It features a working range with feed travels of 1300 mm in the X-axis, 1000 mm in the Y-axis, and 860 mm in the Z-axis. The machine is equipped with a worktable measuring 1000 mm by 1000 mm, capable of supporting parts weighing up to 2000 kg.
The spindle has a maximum speed of 4000 rpm and is powered by an 18.5 kW motor, with a spindle taper of ISO 50 and a diameter of 110 mm. The machine supports a maximum milling cutter diameter of 8 inches and a boring diameter of up to 250 mm. Threading capabilities extend to 2 inches in diameter. The tool magazine holds up to 180 tool pockets, accommodating tools with a maximum diameter of 220 mm (when adjacent positions are empty) and a maximum length of 470 mm. The tool clamping force is rated at 3000 kg.
Positioning accuracy is high, with repeatability within ±0.002 mm and overall positioning accuracy of ±0.01 mm. The worktable can index in 1° increments, and the machine includes six pallets for workpiece handling.
Physically, the machine measures 5070 mm in length, 5450 mm in width, and 3980 mm in height, with a total weight of approximately 28,000 kg. The machine is equipped with a rotary table or work holding fixture and a chip conveyor for efficient chip removal. The control panel includes a CRT screen with multiple buttons and dials, showing signs of wear consistent with use. Overall, the machine appears structurally intact though it shows some wear and dirt accumulation from operation.
