In the processing of parts, it is necessary to pay attention to many details and processing efficiency above. In fact, it is not difficult to improve processing efficiency, but we must ensure the quality of processing while improving processing efficiency, so here we understand how to ensure CNC How about the product processing efficiency of precision parts?
1. Rough division of labor to ensure accurate processing. The characteristics of roughing and finishing are different. For example, in roughing, the workload will be relatively large, such as the amount of cutting and clamping force. Therefore, it is necessary to finish and rough The processing is carried out separately, and the processing conditions are strictly controlled.
Second, choose the right processing equipment.. For finishing and roughing, they have different requirements for equipment. During roughing, you can choose a machine with a low precision for processing, while for finishing, you need to choose a higher performance. Machine tool.
Third, do a good job in the heat treatment of CNC precision parts processing. The implementation of this process has a high impact on the processing quality, and we must pay attention to it.
Fourth, using correct and scientific methods to invest in CNC precision parts processing can meet the needs of the continuous development of the enterprise and make the work perfect. Then, how to do CNC precision parts processing?
1. Choose equipment reasonably
Rough machining of precision parts mainly cuts off most of the machining allowance, and does not require high-precision CNC precision parts processing. Therefore, the roughing should be a high-power and high-precision machine tool, and the relatively high-precision machine tool should be used during the completion process.. Rough and fine Processing on different machines can give full play to the capabilities of the equipment and extend its service life. CNC precision parts processing machine tools.
2. In order to ensure the machining accuracy of CNC precision parts, the coarse and fine mechanical parts are processed well.
Due to the large cutting force during the processing of rough CNC precision parts, the cutting force, clamping force, heat, and the machined surface of the machine parts have obvious work hardening, and the workpiece is in a state of large internal stress. If the rough and rough machine parts are After the processing is completed, the accuracy of the parts will be quickly lost due to the redistribution of stress due to continuous processing. It is used for the processing of some high-precision mechanical parts. After rough machining and finishing, a low-temperature annealing process should be arranged or aged to eliminate internal stress.
3. The heat treatment process is often arranged during the processing of CNC precision parts
The location is arranged as follows: the heat treatment process, the metal that improves its cutting performance, such as annealing, normalizing, and tempering, is generally arranged in the processing of mechanical parts. Eliminate internal stress such as aging treatment, conditioning treatment such as general floor plan, after rough machining, but after completion.. In order to improve the mechanical properties of components, such as carburizing quenching and tempering, generally arranged in the machining of mechanical parts. If the deformation is large after heat treatment, the process after processing must be arranged.
