Single Notching

The single groove blanking process of motor blanking is a kind of blanking process relative to double blanking. Motor fixed, Rotor Core punching using single groove punching process, its mold design, manufacturing are relatively simple, suitable for small batch, variety of production, has the characteristics of low cost, fast change. With the development of advanced punching machine, production efficiency continues to improve, the single punching process is also developing rapidly. For the large motor, because of the cost of the duplex die and the equipment capacity, the single groove is also used. Another advantage of single groove punching is the consistency of groove size. Compound die is the same punch, stator or rotor groove completed at one time. How many slots correspond to the same number of punches, punch size to achieve complete has always been some difficulties: single slot punching is by the same punch to complete all the slots, groove consistency is better.
