2007 Twinhorn VA-500 CNC Vertical Machining Center

This 2007 Twinhorn VA-500 CNC Vertical Machining Center is a Taiwanese box-way 3-axis VMC built by Chi-Fa Machinery in Taichung, configured with 19.69" of X-axis travel, 15.75" of Y-axis travel, and 17.72" of Z-axis travel on a 15.75" x 27.56" working table. The machine runs a BT40 spindle to 8,000 RPM behind a 10 HP motor, cycles tools through a 16-position automatic tool changer, and is controlled by the GE Fanuc 0i-MC — Fanuc's well-known mid-tier VMC control that buyers can still source replacement parts and trained operators for in 2026. Compared to the imported Asian VMCs from this same era that shipped on linear roller guides, the Twinhorn VA-500 was sold specifically on its full box-way / Meehanite-casting platform with pretensioned C3 ball screws on all three axes — the higher-rigidity configuration for shops cutting cast iron, stainless, and stiffer alloys at heavier depths of cut, rather than chasing top rapid speed on aluminum. At 11,595 documented hours running mostly aluminum with a little steel, this VA-500 is positioned as a low-fatigue box-way replacement for any small shop running a tired Bridgeport-class manual mill or an older entry-level VMC needing modern Fanuc control.
