Steering knuckle parts of the main surface is a knuckle spindle surface, surface, the main pin hole and keyway. By the principle known processing, in order to ensure the accuracy of the parts, at the same time, save cost shorten the processing cycle to improve production efficiency. So a good process arrangement and special fixture design essential. In the process of arrangement is not tight reasonable processing requirements, but also consider the operator and processing machinery safety. At the same time the fixture design also consider removing the convenience and safety. The design of a good tooling arrangement route must to process a detailed analysis and careful consideration can reach. So the analysis of a problem is the key. At the same time, repeated adjustment. To seek a better solution. In order to ensure the machining precision of the workpiece and the production rhythm.
