Su minte precision machinery technology (Dongguan) Co., Ltd., the allowance of the light knife should be reasonable, so that the smoothness of the workpiece and the service life of the tool will be better. Before machining precision parts, check whether the tool swing is within the allowable tolerance range with the calibration table. The tool head and lock nozzle can be installed only after being blown clean with wind or wiped clean with cloth before machining. Too dirty will have a certain impact on the accuracy and quality of the workpiece. When clamping, pay attention to see whether the name and model of the workpiece processed by the precision parts are the same as those of the program list, whether the material size matches, whether the clamping height is high enough, and use the caliper to count. The program sheet of precision parts processing should be consistent with the direction of the reference angle marked by the mold, and then check whether the upper 3D drawing is correct, especially for the workpieces that have been drilled with water transportation. Be sure to see whether the 3D drawing is consistent with the water transportation of the workpieces. If it is not clear, it is necessary to timely feed back to the programmer or find the fitter to check the lower 2D drawing to see whether the 2D and 3D reference angles are consistent. The program list of precision parts processing documents should be standardized, including the mold number, name, program name, processing content, tool size, feed, especially the safe length of tool clamping, the reserved allowance of each program, light knife. </div>
CNC precision parts are written into the program in the form of instructions. Cutting parameters include spindle speed, back feed and feed rate. Precision machinery hardware processing first station, our company specializes in precision machinery parts processing, automation equipment parts processing. In the process of precision machining parts, metal materials and spring steel are often contacted. <br>
It is a kind of good elastic steel. Under the condition of quenching and tempering, the elastic stress is used to process and manufacture springs and elastic components, such as mechanical accessory chuck number. <br>
The spring steel can bear the definite load with the elastic deformation ability within the specified range, and there will be no permanent deformation after the load is removed. The special elastic material of spring steel is used in many parts of non-standard automation equipment. <br>

For different machining methods, different cutting parameters need to be selected. When programming precision parts, programmers must determine the cutting parameters of each process, including spindle speed, back feed, feed speed, etc., and input them into the program in the format specified by the CNC system. For different machining methods, different cutting parameters should be selected. Reasonable selection of cutting parameters has a great influence on the surface quality, accuracy and processing efficiency of parts. This is also difficult to grasp in practice, to have rich practical experience to be able to determine the appropriate cutting parameters. In NC programming, it can only depend on the experience of the programmer and the recommended value of the cutting parameters of the tool, and the final cutting parameters will be determined according to the debugging results of the NC program and the actual machining situation. The selection principle of cutting parameters for precision parts machining is to improve productivity in rough machining.
