2011 YAMA SEIKI LP4025 VERTICAL MACHINING CENTERS

Technical Description

The 2011 Yama Seiki LP4025 is a 3-axis large-format gantry-type vertical machining center manufactured by Yama Seiki USA, designed for machining very large workpieces including aerospace panels, shipbuilding components, heavy molds, and large industrial fixtures requiring a wide-area working envelope. The LP4025 provides approximately 157.5 inches of X-axis travel and configurable Y-axis travel up to 157.5 inches, with Z-axis travel ranging from 39.4 to 55.1 inches depending on configuration. The table accommodates very large workpiece loads consistent with the machine's gantry-class construction. The spindle delivers approximately 29.5 HP at up to 4,000 RPM in the standard geared configuration, with optional direct-drive spindles reaching 8,000 to 10,000 RPM for non-ferrous applications. Fanuc CNC control provides comprehensive programming capability and reliable production interface. The LP4025's moving gantry architecture enables machining of extra-large workpieces that would be impractical in a conventional fixed-column VMC. At machine weights and overall dimensions consistent with its large-format gantry classification, the LP4025 requires heavy-duty reinforced foundations and substantial overhead crane capacity for installation. The LP series represents Yama Seiki's large-format gantry machining platform, suited to aerospace manufacturers, shipbuilders, heavy equipment producers, and large mold shops requiring the ability to machine workpieces exceeding 10 feet in multiple dimensions in a single setup.
