NIIGATA HN-50B HORIZONTAL MACHINING CENTER

Technical Description

The Niigata HN-50B is a high-rigidity horizontal machining center designed for heavy-duty and precision milling tasks. It features robust travels with an X-axis movement of 31.447 inches, a Y-axis travel of 27.516 inches, and a Z-axis travel of 21.619 inches, allowing for a substantial machining envelope. The machine is equipped with a BT-50 spindle taper driven by a 20 HP spindle motor, capable of spindle speeds ranging from 20 to 4500 RPM through a geared head system, ensuring flexibility in machining a variety of materials and geometries. It includes an automatic tool changer (ATC) with a large capacity of 180 tools, facilitating extended unattended operation and reducing cycle times. The pallet system supports a 19.654-inch square pallet size, optimizing workpiece handling efficiency. Controlled by a Fanuc 15M CNC system, the center offers precise, programmable control over all machining parameters for complex, repeatable production. Additional features typically associated include a full enclosure splash guard, automatic lubrication of all axes, spindle cooling, and chip conveyor systems to maintain operational cleanliness and machine longevity. This configuration is ideal for industries requiring high-volume, high-precision horizontal machining with rapid tool and pallet changes to minimize downtime and maximize throughput.
