What are the sequences of precision CNC machined parts ?

For the processing cnc machining industry, the order is very important. It is related to the quality assurance of the products. If there is a wrong order, it will easily cause great losses. If it is serious, it must be repeated. It is a bit serious, these CNC machining products are scrapped. , precision parts processing is one of them, What is its order ?
First, the order of the precision CNC machining parts processing should be considered according to the structure of the parts and the condition of the blank, as well as the need for positioning and clamping. The key point is that the rigidity of the workpiece is not destroyed.
  (1) The processing of the previous process cannot affect the positioning and clamping of the next process, and the intermediate precision machining process must be considered in the middle.
  (2) First, the inner cavity is added, and then the outer shape processing step is performed.
  (3) It is best to connect the same positioning, clamping method or the same tool to reduce the number of repeated positioning, the number of tool changes and the number of moving plates. Dongguan CNC machining,
  (4) In the multiple processes carried out in the same installation, the process of reducing the rigidity of the workpiece should be arranged first.
  Second, the tool concentration sequence method is to divide the process according to the tool used, and use the same tool to finish all the parts that can be completed on the part. Use the second knife and the third handle to complete other parts that they can complete. This reduces the number of tool changes, compresses the dead time, and reduces unnecessary positioning errors.
  Third, the processing part of the order method For the processing of a lot of CNC machining parts, the processing part can be divided into several parts according to its structural characteristics, such as internal shape, shape, surface or plane. Generally, the plane, the positioning surface, and the rear processing hole are first processed; the simple geometric shape is processed first, and the complex geometric shape is processed; the lower precision part is processed first, and the processing precision requirement is higher.
 The above is the order of processing precision CNC machining parts. It is necessary to operate according to these several items, which will greatly reduce your processing risk.
