With the same double-column structure that has been so widely praised in Okuma's double-column machining centers, the VTR-A series machines provide both high rigidity and high accuracy in a large work envelope. This series is designed to handle heavy-duty cutting, including difficult-to-machine and thin or tall cylindrical materials and can easily cut or mill workpieces of various sizes. With optional Thermo-Friendly Concept features, added thermal stability can bring even greater accuracy and repeatability for even the most demanding of tolerances.
