NOMURA BORING BN-135QF/R5 HORIZONTAL MACHINING CENTER

Technical Description

The Nomura BN-135QF/R5 Horizontal Machining Center is a robust CNC boring mill designed for heavy-duty horizontal machining tasks. It features a 70" x 78" table capable of supporting workpieces up to 26,400 lbs, with optional indexed or rotary table supports available. The spindle is horizontally oriented with a #50 taper, delivering up to 1,000 RPM and powered by a 40 HP motor rated for 30-minute cycles. Tool handling is managed by an automatic tool changer (ATC) supporting up to 60 tools, with optional pallet changing functionality allowing two pallets for efficient workpiece handling. This machining center operates with 4 axes standard, with an option to add a fifth axis for enhanced machining flexibility. Axis travels are extensive: 275" on X, 137" on Y, 27.6" on Z, with full 360° rotation on the B axis. Maximum feed rates reach 118 inches per minute, and rapid traverses up to 236 inches per minute, facilitating high-speed machining operations. The machine's construction emphasizes rigidity and precision, using large-scale components and hardened guideways to reduce vibration and deflection during operation. It is equipped with features such as coolant-through spindle and chip conveyance for improved machining conditions. Designed for demanding industrial manufacturing, the BN-135QF/R5 supports large, complex workpieces with precise, reliable horizontal boring and milling capabilities.
