Step sequence of CNC precision machining
Whether it is CNC precision machining or everything we do in life, we must be orderly. Only in this way can a product or thing be made more perfect.
It is like CNC precision machining operations, which all need to be performed in sequence. If CNC precision machining is not carried out in accordance with the operation sequence, it is easy to cause machine failure in the process, and serious personal safety will occur. Therefore, when we are doing CNC precision machining, employees must pay attention to the safety operation sequence to avoid accidents!
A CNC precision machining often has several surfaces that need to be processed. These surfaces not only have certain precision requirements, but also have certain positions on each surface. Require. In order to meet these precision requirements, the machining sequence of CNC precision machining surfaces cannot be arranged arbitrarily, but must be processed in a certain sequence. This is the selection and conversion of positioning datums that determine the processing sequence, and the pre-process prepares the positioning datum for subsequent processes. the rules.
The first thing to do is to prepare for starting the machine
The CNC machine tool returns to the reference zero position of the machine tool every time it is turned on or the machine tool is reset by emergency stop. (ie, return to zero), so that the machine tool has a reference position for its subsequent operations.
The second step is to be precise and then operate
cnc precision machining as a precise surface should be carried out at the beginning of the cnc machining process Machining because it is used for positioning when machining other surfaces in subsequent operations.
The third step is rough base precise positioning
When cnc precision machining precise surface, it is necessary to use rough base for precise positioning. In single piece, small batch production, or even batch production, for castings and forgings with complex shapes or large sizes, as well as blanks with large dimensional errors, the scribing process should be arranged before the machining process to ensure accurate machining. Provide alignment benchmarks.
The fourth step requires more precise machining of CNC machining
After we have finished the precise machining, then we will deal with the higher precision machining. Roughing, semi-finishing and finishing are performed on each major surface. Surfaces with particularly high precision requirements also require finishing.
The fifth step of adjustment
cnc precision machining Before machining the important surface, the precision should be rested once, in order to ensure the important surface machining accuracy.
The last is the process of rejects
For the processes that are prone to rejects during CNC machining, finishing and finishing can be properly placed. On the front, some minor surface machining can be placed after it.
