The Nomura Boring BN-135QF/R1 is a robust 4-axis horizontal machining center (with optional 5-axis capability) designed for heavy-duty production work on large workpieces. The machine features a substantial work table measuring 70 inches by 78 inches and accommodates workpieces up to 26,400 pounds, making it suitable for large-scale industrial components. The horizontal spindle utilizes an ISO 50 taper configuration with a maximum speed of 1,000 RPM and 40 horsepower (30-minute rating), prioritizing high torque output over spindle speed for demanding cutting operations on tough materials. The machine's extensive travel capabilities include 157 inches on the X-axis, 78 inches on the Y-axis, and 27.6 inches on the Z-axis, enabling machining of large, complex geometries. All linear axes achieve rapid traverse rates of 236 IPM with 118 IPM cutting feedrates, ensuring efficient material removal and reduced cycle times. The B-axis provides unlimited 360-degree rotary capability for comprehensive multi-surface machining access. The machine is equipped with an automatic tool changer accommodating up to 60 tools, supporting rapid tool changes to minimize idle time during production runs. Optional pallet changer functionality with two-pallet capacity enables lights-out machining capabilities and improved throughput. The available 5-axis upgrade expands machining versatility for contoured surfaces and complex part geometries, while optional indexing and rotary table attachments further enhance application flexibility for specialized production requirements.
