Rotary stone engraving machine the equipment after the update for many years in the technology generated automatically engraving and cutting equipment, it can be processed marble, granite sculpture model, shallow relief, decorations, fireplace, shaft, stigma and statue. The device has a X, y, Z axis and X axis to rotate around the A, mainly by the control platform system, the three directions of the two work stations and spindle system. Linear motion axis three direction respectively by the stepper motor control through the rolling pair. The spindle is provided with a saw blade for cutting and milling head, and also provided with a saw blade double speed motor and the milling head double speed motor, used to control the processing rate of different. The two stage is a fixed table, a rotary table. Stone processing piece clamping clamp plate in the rotary table of the headstock, and the other end by a tailstock clamping, clamping structure by hydraulic. Through the program control of diamond head carved the three directions of movement and stone processing a slew rate, can be carved out of a variety of complex patterns. The centralized lubrication and hydraulic system of moving parts adopt, at the same time with the water tank can be collected and recycled application.
