Machining steps

The operation of machinery is very important. If there is a wrong step in the operation, the consequences may directly affect the quality of the product. These are not what we want, so we must follow the steps in the operation. Let’s learn about the specific steps of machining?

1. Finishing: this processing principle is roughly some grinding and polishing, which is usually carried out after the product has completed the structure.
2. Face before hole: in the process of precision mechanical parts, for the workpiece such as bracket, it is necessary to carry out both plane processing and mechanical hole processing. In order to make the accuracy error of the hole processed smaller, machining the plane before processing the hole is conducive to reducing the error.
3. Dividing the processing stage: when the product is in the precision mechanical parts, the processing degree needs to be divided according to different product requirements. If the accuracy requirement is not high, then a simple rough machining stage is OK. The product schedule requirements are more and more strict, the follow-up will be semi finishing and finishing stage.
4. Datum first: when using mechanical equipment to process products, a datum plane must be determined, so that there can be a positioning reference in the subsequent processing. After the datum plane is determined, the datum plane must be processed first. In precision mechanical parts, there will be a lot of workpieces are not produced by one-time production, but when the workpiece is produced, it is just a rough model.
