2011 YAMA SEIKI AF1250 VERTICAL MACHINING CENTERS

Technical Description

The 2011 Yama Seiki AF1250 is a 3-axis vertical machining center manufactured by Yama Seiki USA, representing the largest-envelope model in the AF high-speed series for production milling of medium-to-large workpieces at elevated spindle speeds. The AF1250 provides 49.2 inches of X-axis travel, 24.4 inches of Y-axis travel, and 24.4 inches of Z-axis travel, with a table measuring 53.1 by 24.4 inches. The 25 HP spindle reaches 12,000 RPM standard — with a 15,000 RPM option available — enabling high-speed cutting in aluminum structures, precision molds, and non-ferrous components. Fanuc CNC control provides high-speed contouring capability and a comprehensive production programming interface. The AF1250's extended travel and high spindle speed make it suitable for manufacturers producing large aluminum aerospace components, automotive body tooling, and precision mold cavities requiring a combination of large working envelope and high-speed machining capability. The machine's robust construction provides the rigidity needed to maintain accuracy at elevated spindle speeds during aggressive feed-rate cutting passes. Yama Seiki's AF series machines are positioned in the North American market as cost-effective alternatives to Japanese-built high-speed VMCs, combining reliable Fanuc control with competitive Taiwanese manufacturing quality. The 2011 AF1250 provides a practical and capable large-envelope high-speed VMC for shops in aerospace, automotive, and precision manufacturing sectors.
