NOMURA BORING BN-150QF/R4 HORIZONTAL MACHINING CENTER

Technical Description

The Nomura Boring BN-150QF/R4 Horizontal Machining Center is a robust CNC boring mill designed for heavy-duty machining applications with a maximum workpiece weight capacity of 44,000 lbs. It features a large 78" x 98" work table, supporting extensive machining operations on sizable components. The machine is equipped with a horizontal #50 taper spindle capable of up to 1,000 RPM, powered by a 40 HP motor rated for a 30-minute duty cycle, providing substantial torque and cutting power for precise material removal. The spindle’s horizontal orientation facilitates stable and efficient boring and milling. This machining center supports a 4-axis configuration, with an optional 5-axis capability, enabling complex contouring and precision part fabrication. Axis travels include X: 157", Y: 137", Z: 236", and a full 360° B-axis rotation, allowing for flexible machining geometries and access. Rapid traverse speeds reach up to 236 inches per minute on linear axes, optimizing throughput and cycle times. The machine is equipped with an automatic tool changer (ATC) accommodating up to 60 tools, enhancing operational efficiency by minimizing manual intervention during tool changes. Additional options include an indexing table, rotary table, and pallet changer with two pallets, further increasing versatility and reducing setup times. Heavy-duty construction, combined with precision ball screws and advanced servo motors, ensures minimal backlash and high contouring accuracy. The Nomura BN-150QF/R4 system incorporates robust guiding ways and slide covers to protect against contamination and maintain machining precision over extended use. This unit is ideal for machining large, complex parts with demanding accuracy and rigidity requirements.
