NIIGATA MACHINE TECHNO USA, INC. HN50D HORIZONTAL MACHINING CENTER

Technical Description

The Niigata HN50D is a heavy-duty horizontal machining center featuring a solid meehanite cast iron frame with induction-hardened boxways hand-scraped for superior accuracy and rigidity. It offers 31.5" X-axis, 27.6" Y-axis, and 22.8" Z-axis travel with rapid traverse rates of 1,181 ipm across all axes. The machine accommodates workpieces up to 1,760 lbs on a 19.7" square table and includes a standard pallet changer with two-pallet capacity. The horizontal spindle utilizes a CAT 50 taper with standard speeds to 6,000 rpm and optional speeds to 12,000 rpm, generating extremely high torque through gear-driven design. The 35 hp spindle delivers robust cutting capability for demanding applications. The automatic tool changer manages 60 tools standard, expandable to 230 with optional configurations, featuring 6.8-second tool change time. The machine features a three-axis standard configuration with optional four-axis capability, including a 360-degree rotary B-axis for enhanced flexibility. Controlled by Fanuc 30iB (31iB) CNC, the HN50D provides outstanding stability and vibration damping through extensive ribbing in the machine frame. The combination of wide boxways, hand-scraped axes, and rigid construction enables long-term accuracy maintenance and superior machining performance for heavy-duty production environments.
