Abstract：Based on the working principle of the backstop,the structural characteristics and technical requirements of the wedge block,a machining process route for the wedge block has been developed.By designing an open elastic sleeve,the center hole was drilled on the lathe,laying the foundation for subsequent eccentric arc grinding.By using formed arc milling cutters to achieve semi-precision machining of eccentric arcs.By designing an eccentric arc tire grinding fixture,precision machining of the eccentric arc of the wedge block has been achieved.The inspection and experimental verification have been carried out,and this process method can achieve a surface roughness of≤0.8 μm on the circular arc surface of the wedge block(up to 0.4 μm on the working surface),a coaxiality of ≤0.02 mm,and all performance of the backstop meet the technical requirements.
