SHIBAURA MACHINE CO. BMC-800 HORIZONTAL MACHINING CENTER

Technical Description

The Shibaura Machine BMC-800 is a three-axis horizontal machining center designed for stable, powerful cutting and precision machining operations. The machine features a 31.5" x 31.5" pallet with a maximum workpiece capacity of 4,400 lbs and employs linear roller guides on all axes (X, Y, Z) for enhanced rigidity and positioning accuracy. The horizontal spindle operates at 5,000 RPM with a CAT 50 taper and delivers 30 HP at a 30-minute rating, supported by a 38-position automatic tool changer with optional expansion to 90 tools. The machine provides rapid traverse rates of 18 m/min (708 IPM) and maximum feedrates of 10 m/min (394 IPM) across all axes, minimizing idle time for improved productivity. Travel distances measure 63" on the X-axis, 39.4" on the Y-axis, and 47.2" on the Z-axis, with extended stroke options available. The BMC-800 incorporates thorough thermal displacement compensation features including an oil-cooled spindle drive motor, ball screw cooling unit, and linear scale feedback systems to maintain machining precision. A parallel shuttle-type automatic pallet changer with two pallets enables operators to setup workpieces during machine operation, enhancing efficiency. The machine is controlled by the TOSNUC 999 CNC system and includes optional features such as a 10,000 RPM high-speed spindle, Z-axis thermal displacement compensation function, and automatic Renishaw measuring probe for advanced precision work.
