In machining, our staff must follow the operating standards. But how do you get it right when formulating a machining process for a component? Let's take a look at Changzhou Machinery Parts Processing.
1. Select the appropriate processing method for each surface according to the requirements of the machining accuracy and the roughness of the machined surface.
2. The positioning benchmark of each process should be effectively selected according to the thickness benchmark requirements.
3. On the basis of the analysis of the parts, distinguish the rough and fine machining, and clarify the concentration of each process, and then arrange the processing sequence of each surface reasonably, and then formulate the machining process of the parts. route.
4. Make clear the machining allowance of each process and the dimensions and tolerances of each process.
5. Under the premise of ensuring quality and quantity and taking into account the economy, select suitable machine tools and tools, clamps, measuring tools and cutting tools.
6. Clarify the technical requirements and inspection methods of each process.
7. In order to ensure the rationalization of production and the balance of rhythm, it is necessary to select suitable cutting amount and time quota, and cannot modify it casually.
8. The staff shall fill in the process documents as required.
Let's discuss with Changzhou mechanical parts processing.
1. On-site investigation and research is a very important step. As far as possible, collect the remains of the failed parts as carefully as possible, and take pictures to record the current situation, so as to clarify the key analysis objects. The test samples should be taken from the failed parts. from location.
2. Carefully record and sort out the relevant materials of the failed parts, such as design drawings, production and processing methods and application conditions.
3. Analyze the selected specimens to clarify the origin of failure and failure mode. Scanning electron microscope fracture analysis to determine the origin of failure and failure mode; metallographic analysis to determine the internal quality of the material.
4. Measure the relevant data of the test sample: functional test, tissue analysis, chemical composition analysis and non-destructive testing, etc.
5. Analysis of fracture mechanics.
