Therefore, re-enacted box parts machining process time should be how to ensure the accuracy of holes focus to consider. Accuracy and surface roughness requirements, the purpose is to ensure that the bearings installed in the hole and shaft of the rotary precision; plane flatness and straightness, the purpose is to ensure assembly of the contact surface after the machine-oriented surface of the contact stiffness and positioning accuracy; the location of the holes is a box-type parts precision of the most important technical requirements, including the location of hole and hole box parts machined surface accuracy of the main problems is the plane and holes. Its technical requirements is mainly reflected in three asp...
