What factors should be paid attention to when manufacturing precision metal parts?

Before working, the machine should carefully check whether the processing part is filled with lubricating oil, and then turn it on for 1-3 minutes to check whether it can work normally. If there is a fault, it is prohibited to operate; also, during the operation, the posture must be correct and adequately maintained For mental work, if the body feels unwell, immediately leave the job and report to the leader. To avoid accidents, the dressing requirements must be qualified; secondly, to change the processing mold, turn off the power first, and then start the installation after the machine stops running, debug the mold, after the installation is completed, manually flywheel test punching several times, check whether the upper and lower molds are symmetrical and whether the screws are Tighten well, and whether the blank holder is in the right position; the most important thing is to wait for everyone else to leave before you can start the switch and start working. Remember, after the machine is turned on, don’t put your hands into the working area and pick and place the workpiece in the die. Special tools must be used at the time. If there is an abnormal sound or the machine malfunctions, immediately cut off the power and stop the operation before checking the fault. Finally, the power should be turned off after work, the finished products, side materials and debris on the job should be sorted out, and safety and hygiene should be determined. The processing method of precision parts firstly depends on the technical requirements of the surface of the processed part. It should be noted that these technical requirements are not necessarily the requirements specified on the part drawings, and sometimes they may be due to technological reasons. Certain aspects are higher than the requirements on the process drawings, for example, because the benchmarks do not overlap and increase the processing requirements of the surface of the hardware parts, or are used as the accuracy benchmarks to put forward higher processing requirements, when the technology of the precision parts processing surface is clarified After the requirements, you can choose the final processing method that can guarantee the processing requirements based on this, and determine the processing methods that require several procedures. The selected part processing method should meet the quality of the parts and the requirements of good processing economy and efficiency. Therefore, the following factors need to be considered when choosing a precision metal processing method: 1. The processing accuracy and surface roughness that can be obtained by any kind of precision parts processing method has a relatively large range, but the knowledge is in some comparisons. A narrow range is economical. The processing accuracy in this range is the economical processing accuracy. Therefore, when choosing the processing method, you should choose the corresponding processing method that can obtain economical processing accuracy; 2. Need to consider the precision hardware parts 3. It is necessary to consider the structural shape and size of the hardware parts; 4. It is necessary to consider the requirements of production efficiency and economy. In mass production, high-efficiency advanced technology should be used, and even fundamental Changing the manufacturing method of the blank can reduce the amount of movement of precision machining; 5. It is necessary to consider the existing processing equipment and technical conditions of the manufacturer or workshop. When selecting the processing method, you should make full use of the existing manufacturing equipment to tap the potential of the enterprise , Give full play to the enthusiasm and creativity of workers, but we should also consider continuous improvement of existing processing methods and equipment, and use cutting-edge technology to improve the level of technology; the above are several factors that need to be considered in the processing of precision hardware parts.
