What is the order of CNC machining? For precision part processing, it must be based on the structure of the part, the condition of the blank, and the requirements of positioning and clamping. The key point is that the rigidity of the workpiece will not be damaged. There are the following points:
1、 The familiar understanding of precision parts processing technology can be divided into several points:
- How to handle the previous process will not affect the positioning and clamping of the next process. The middle cross section has a general fine part processing process.
- First stop the adding process of the inner cavity, and then stop the shape processing process.
- It is better to use the same positioning and clamping method or the same tool to stop the process, so as to reduce the number of repeated positioning, tool change and the number of moving pressing plates. Dongguan machining factory method.
- In multiple processes stopped in the same device, the process of damaging the workpiece stiffness shall be arranged first.
2、 The precision machining process of all parts can be completed by using the same tool sequence. Using other tools can successfully complete other parts. This can reduce the number of tool changes, shorten the dead time and reduce unnecessary positioning errors.
3、 Sorting method of processing parts: for parts with a large amount of processing content, according to their structural characteristics, the processing parts can be partially red, such as internal shape, shape, surface or plane. Common machining plane, locating surface and post machining hole; First deal with simple geometry, and then deal with complex geometry; Firstly, the parts with low precision shall be processed, and the parts with high precision shall be processed.
The above is the steps of precision CNC machining.
