Makinos GF12/20 vertical machining center offer high performance machining of medium and large dies and molds. Equipped with a standard 15,000 rpm spindle, the GF12/20 delivers superb accuracy, ultra fine finishes and fast cycle times. Makinos patented SGI.3 features high resolution feedback and greatly improved servo control for higher surface finish capabilities. The GF12/20s 15,000 rpm spindle has patented core cooling and under race lubrication to maintain thermal stability. Makinos advanced spindle minimizes thermal distortion at high speeds to provide exceptionally stable machining accuracy. The integrated construction of the spindle and drive motor also reduces vibration during high-speed operation to ensure high-quality machined surfaces. These finishes are made ultra fine using Makinos proven Flush Fine (FF) advanced milling process, which virtually eliminates the need for polishing.
The GF12/20s superior capabilities are backed by the following features:
