The vertical follow-up turning and grinding machine adopts a vertical high-rigidity structure, integrating turning and grinding into a single machining process. It can complete the entire machining process in one setup, effectively avoiding errors from multiple setups. It has high machining accuracy and strong stability. With a multi-axis CNC system, it can easily process various complex and irregularly shaped workpieces. It also has the advantages of high automation, high machining efficiency, and low material consumption. It is widely applicable to disc, ring, and irregularly shaped precision workpieces such as flanges, valves, motor housings, and bearing rings. It can also process materials such as ceramics, silicon carbide, and stainless steel. It is an ideal equipment for high-precision and high-efficiency machining in industries such as bearings, aerospace, and valves.
