Formulation of CNC machining route: First, we should carefully analyze the geometric structure of the parts, the accuracy requirements of the core parts of the accuracy index, material characteristics, heat treatment requirements and performance requirements, and then reasonably select the blank of the parts, reasonably use the machining equipment, take reasonable stress relief process measures and other reasonable configuration of many process links. In the production organization process, we should strictly follow the process flow, During the process, strict inspection shall be carried out. For general precision parts, the process route is: rough processing - aging - semi finishing - finishing. In the face of precision mechanical parts machining, such CNC machining route is obviously not enough. To ensure the machining requirements, the process route must be lengthened, the aging treatment should be appropriately interspersed, and the ultra precision machining procedures should be configured.
CNC machining
Generally, the CNC machining process is: one rough processing - one thermal aging - two rough machining - two thermal aging (or vibration aging) - semi finishing - vibration aging - finishing - natural aging (or low temperature stabilization) - machining. Among them, the heat treatment requirements of parts should be properly interspersed according to the different requirements of the overall hardness, local hardness and surface hardness of the parts. The stability treatment of the machining accuracy of mechanical parts is also very critical and complex. One or two simple CNC machining methods can no longer meet the requirements. Usually, multiple methods are adopted as required, such as stress annealing, low temperature stability treatment, vibration aging, natural aging, Even adopt cold treatment and other technological means to ensure the accuracy and stability of precision parts.
