The invention relates to a template type arc moulding machine which comprises a rack. A lifting assembly, a rotating assembly and a template are arranged on the rack. The rotating assembly comprises a vertical rotary shaft, a rotating frame, a connecting plate, an air cylinder and a transverse guide rod. Telescopic rods and an air cylinder are arranged on the rotating frame. The rear ends of the telescopic rods are connected with the connecting plate. The lifting assembly comprises a lifting motor, a motor support, a lead screw, vertical guide columns, a fixed frame, a control motor, bearings, a rotating shaft and a grinding wheel. The lifting motor, the control motor and the vertical guide columns are arranged on the motor support. Each bearing is arranged at the end of the corresponding guide column. The rotating shaft cooperates with the bearings. The grinding wheel is arranged on the rotating shaft. A vertical sliding groove is formed in the rear side of the fixed frame. The cooperation end of the rotating shaft and the control motor penetrates the sliding groove. According to the template type arc moulding machine of the scheme, the multiple motors are used for driving different modules to machine stone, operation is convenient, and product forming grain is smooth.
