     Abstract: With comparison of roughcast piston quality home and abroad, this paper proposed  a new design concept of tools which  has features like low cost and easy operation. In addition, this paper developed a fixture, which could be applied in single and automatic piston machining, achieving  machining at high efficiency, high precision, high quality and low cost.
