Okuma MC-1000H Horizontal Machining Center (HMC) with a 6-pallet Automatic Pallet Changer system

The 2002 Okuma MC-1000H Horizontal Machining Center (HMC) with a 6-pallet APC (Automatic Pallet Changer) system is a heavy-duty, high-precision manufacturing cell engineered for long-duration, automated "lights-out" production.Core Machine SpecificationsPallet Size: 1,000 mm × 1,000 mm square pallets.X-Axis Travel: 1,600 mm (63.0 inches).Y-Axis Travel: 1,300 mm (51.2 inches).Z-Axis Travel: 1,000 mm to 1,200 mm depending on exact spindle/column configuration.B-Axis Indexing: 1-degree standard indexing table (NC 0.001-degree full 4th axis contouring was available as a premium factory option).Spindle & ToolingSpindle Taper: Robust BT50 or CAT50 heavy-duty taper.Spindle Speed: Typically standard at 4,500 RPM to 6,000 RPM geared head for high torque; some high-speed factory variants reached up to 10,000 RPM.Drive Motor: High-output 22 kW to 30 kW motor.Automatic Tool Changer (ATC): Upgraded matrix chain magazine. Standard twin-pallet systems usually carried 40–80 tools, but 6-pallet pool cells from this era were typically packaged with 120, 150, or 180 tool stations to support multi-part unattended operations.Automation & System Features6-Pallet Pool System: Operates on an automated carousel or linear pallet pool loop. This design allows operators to setup, load, and unload parts on external stations while the spindle continuously cuts a separate part inside the enclosure.CNC Control: Equipped with the signature Okuma OSP-U100M or OSP-7000M controller.Stability & Rigidity: Features Okuma’s highly rigid box-way bed structure, dual ball-screw drives, and integrated ball-screw core cooling to tightly manage thermal expansion during prolonged run times
