Sheet Metal Processing manufacturers mainly refer to various profiles of machined parts, which are developed and produced according to market demand within a certain range. Generally speaking, there are two types of main machined parts: one is the workpiece, then this workpiece is called mortise and tenon, so it is called mortise and tenon; the other is the workpiece. Generally speaking, mortise and tenon are workpieces that need to be completed in a short time because of their manufacturing difficulty and processing cycle. Mortise and tenon processing is to build and process workpieces according to the size of the workpiece. The main function is to fix the parts in the workpiece, and then process various shapes of parts in other ways. As the main production material, whether it is from manufacturing or processing, it needs to be completed under certain conditions, which is a difficult point for most ordinary parts. Generally speaking, it is still necessary to consider the time, the size of the production line, the difficulty of processing and the application of mortise and tenon in processing. First, the mortise and tenon process flow and processing method. Computer numerical control processing machine tool: processing drawings: standard parts appearance size, number of parts, part type, roughing and processing technology, etc. Using advanced numerical control drilling machine, grooving at the top, cutting thin-walled parts with a diameter of more than 2.5mm, and then cutting the finished product through milling. The second kind of mortise and tenon, for small parts, is forced to be processed by the "second kind" mortise and tenon. By hand and mechanical hand grasping the workpiece, processing several parts, and then after five processes, a single piece completes the processing of each time node. *** After the total assembly, the processing of each time node is carried out. At the same time, the shearing depth must be guaranteed to ensure the accuracy of the processing. After the processing is completed, the preliminary processing is carried out, and each part must be cut according to the method of the previous process. At the same time, the model and wall thickness of the processed parts must be processed according to certain procedures, thereby ensuring the processing time. The fourth is electroplating. Winning by quality and fine industry is the company‘s consistent production principle. As a pioneer in the precision sheet metal industry, the company adopts the precision management concept, from consulting, design, sampling, and mass production to one-stop service. To establish the ecological development vision of "design one platform and one service".
