2010 YAMA SEIKI SP4016 VERTICAL MACHINING CENTERS

Technical Description

The 2010 Yama Seiki SP4016 is a 3-axis bridge-type double-column vertical machining center manufactured by Yama Seiki USA, designed for large-format production milling of aerospace structures, heavy molds, large dies, and industrial components requiring wide-area table coverage and heavy spindle power. The SP4016 provides 157.5 inches of X-axis travel, 63 inches of Y-axis travel, and 30 inches of Z-axis travel. The 35 HP spindle reaches 8,000 RPM, enabling effective cutting performance across a range of materials including aluminum, steel, and cast iron, with sufficient power for both heavy roughing and precision finishing operations. Fanuc CNC control provides high-speed contouring capability and comprehensive G-code programming suited to complex large-format machining programs. The SP4016's double-column bridge structure ensures rigidity across its 157-inch X-axis stroke, maintaining accuracy during heavy cutting passes on large workpieces. The extended X-travel makes the SP4016 particularly suited to manufacturers producing long structural components, rail equipment, shipbuilding parts, and large tooling plates requiring more than 10 feet of longitudinal travel in a single clamping. Yama Seiki's SP series positions the brand in the large-format double-column machining center segment, offering a cost-competitive alternative to Japanese and European bridge mills for North American manufacturers requiring large-envelope capability. The machine requires heavy foundations and adequate overhead crane access for installation and servicing.
