Commensurate with each other using the tailstock sleeve parts and is part of the main processing surface of which is cylindrical and surface Mohs fourth hole. According to the standard process can be understood, to ensure precision cylindrical surface is certainly better than the hole to ensure the machining accuracy easier. Therefore, in accordance with the design standards before surface after hole. And the outer surface of the hole and working very clear divided into roughing and finishing stages, so you can ensure accuracy. The ins and outs of the process using a common tool. Which of Mohs fourth bore and outside surface roughness is relatively high, after grinding to achieve the roughness. Keyway milling 8mm, mainly outside circular face of the sleeve bore centerline do positioning reference, I used the V-block as a positioning jig, analyze the sources of error of positioning fixture for control assurance and enhancement machining accuracy is very important. The main body of the text is that through the process and the mechanical properties of the machine tailstock sleeve is analyzed on the processing technology of scientific and reasonable arrangement, combined with the actual operation, the successful completion of the final study design C620 machine tailstock sleeve C
