2007 YAMA SEIKI VMB850 VERTICAL MACHINING CENTERS

Technical Description

The 2007 Yama Seiki VMB850 is a 3-axis box-way vertical machining center manufactured by Yama Seiki USA, the compact model in the VMB series designed for precision heavy-duty milling of medium workpieces with the rigidity and accuracy retention advantages of box-way construction. The VMB850 provides 33.5 inches of X-axis travel, 23.6 inches of Y-axis travel, and 23.6 inches of Z-axis travel, with a table measuring 41.3 by 23.6 inches. The 20 HP spindle reaches 8,000 RPM through a two-speed geared headstock, enabling high-torque cutting at low speeds for heavy ferrous material removal while maintaining adequate speed for finishing operations. Fanuc CNC control provides reliable G-code programming and a well-supported production interface. At approximately 12,500 pounds with overall dimensions of approximately 123 by 90 by 110 inches, the VMB850 reflects the heavy cast iron box-way construction that distinguishes this series from linear-guide VMC alternatives. The VMB850 is suited to die/mold shops, toolrooms, and contract manufacturers producing medium-scale components in steel, cast iron, and hard alloys where long-term accuracy retention and vibration damping are prioritized. The VMB designation represents an earlier naming convention for what became the BM series in later Yama Seiki production years, with the two series sharing the same fundamental box-way platform. The 2007 VMB850 provides a reliable and cost-effective box-way VMC option in the North American used market.
