Abstract: Aiming at the problems such as low rigidity of thin-walled V-tooth surface ring products with corrosion resistance and difficult to machine the Hastelloy materials, easy vibration in turning and unable to guarantee tolerance, a set of innovative processing methods and technologies for clamping materials is put forward in this paper. Using position of the inner hole of the workpiece, turning is carried out by using the friction between the mechanical device and the workpiece to realize all cutting operations in a clamping station, which reduces the impact on the product caused by turning over and aligning deviation, and also effectively improves the manufacturing quality and efficiency. Through the success of tackling the problem of V-shaped tooth ring made of Hastelloy, it is verified that the new clamping method can effectively solve the turning problem of this kind of products. This turning method has a good reference and popularization value for production of the similar thin-walled rings.
