1989 MATSUURA RAIIIF VERTICAL MACHINING CENTERS

Technical Description

The 1989 Matsuura RA-IIIF is a 3-axis vertical machining center from the Matsuura RA series, equipped with an integrated twin-pallet automatic pallet changer (APC) for continuous, unattended production. The 'F' suffix denotes this dual-pallet flexibility. Each pallet measures 420 x 800 mm (16.5" x 31.5") and supports a maximum workpiece load of 300 kg (660 lbs). Axis travels are 760 mm (29.9") in X, 440 mm (17.3") in Y, and 488 mm (19.2") in Z, with spindle nose-to-table distance of 145 mm to 633 mm. The BT40 spindle is rated at 20 HP and achieves a maximum speed of 15,000 RPM, delivering high-speed capability well beyond the standard RA-III spindle range. A 30-tool arm-type ATC supports complex multi-operation programs. The CNC is a Yasnac i80 (Yaskawa) controller with full EIA/ISO G-code and conversational programming, rigid tapping, and canned cycle support. Machine weight is approximately 15,000 lbs (6,800 kg). The RA-IIIF combines a generous work envelope with twin-pallet automation and a high-speed spindle, making it a versatile platform for precision batch production of medium-sized components in aerospace, medical, and general engineering applications.
