Cold cutting saw is a very high demand for power and precision equipment. Therefore, the servo motor can only be selected. Eliminate the mechanical clearance function in the working process, reduce the influence on the cold cutting saw blade, reduce the loss of the saw blade, reduce the production cost; Electrical control choose imported motor and driver, so that the operation of the equipment more stable and reliable; Human-machine interface is easy to understand and fluent, the equipment is easy to operate and easy to use; It has fault-tolerant processing such as sliding of steel tube and fixture to avoid abnormal damage of cold cutting saw blade and mechanical equipment. The overall operation of the equipment is stable and reasonable to avoid mechanical losses to a greater extent.
