NOMURA BORING BN-135QF/R4 HORIZONTAL MACHINING CENTER

Technical Description

The Nomura BN-135QF/R4 Horizontal Machining Center is a heavy-duty CNC floor-type boring mill designed for precision horizontal machining. It features a large table measuring 70" x 78" capable of supporting workpieces up to 26,400 lbs. The machine operates with a powerful 40 HP spindle motor rated for 30 minutes, utilizing a #50 taper spindle rotating up to 1,000 RPM. The spindle supports coolant-through and chilling options to enhance machining stability. Tool handling is managed by an Automatic Tool Changer (ATC) accommodating up to 60 tools, with zero-second chip-to-chip tool change time, and optional pallet changer with two pallets to optimize workflow. The machining center employs 4 axes (X, Y, Z, and B rotary axis) with travel capacities of 157" (X-axis), 137" (Y-axis), 27.6" (Z-axis), and 360° rotary motion on B-axis, achieving rapid traverse rates of 236 inches per minute. Optional support rotary and indexing tables enhance workpiece positioning and flexibility. Its robust construction ensures accommodation of large, heavy workpieces and complex machining operations, supported by CNC control (commonly Fanuc 31i-MB or equivalent). This machine combines extreme rigidity and precision, suitable for heavy industrial applications requiring large-scale boring, milling, and complex machining, offering high metal removal rates with tight tolerances and extended tool life. It is optimized for stability, reduced cycle times, and flexible tooling capacity, making it ideal for demanding manufacturing environments.
