Nowadays, the equipment for processing special-shaped stone products is developing towards high efficiency, intelligent and multifunction. Based on the features of stone processing technology, a sawing-milling compound machining center with eight axes and double five-axis simultaneous control for special-shaped stone products was designed. The dynamic performance and processing capacity were tested. Research shows that the sawing and milling compound machining in the same horizontal slide saddle is practicable. This machine can realize both vertical and horizontal machining under five-axis simultaneous control, and its machining accuracy is better than the normal industrial standard.
