The first, the tool concentrated sequence method.
The principle of this method is very simple, it is based on the tool used to divide the process, simply put, is to use one knife to finish all the machining procedures on the part, and then use a second knife, and then a third knife until all the machining procedures are completed. This processing method is to reduce the inconvenience caused by frequent tool change, can also speed up the overall progress of mechanical drawing processing, but also can reduce unnecessary positioning errors.
The second, rough and finish processing method. In simple terms, it is to do rough machining or semi-finishing of a single part first, and then finish the operation. Then, for a large number of parts, the first unified rough processing, and then semi-finishing, and finally complete the mechanical finishing work. We should pay special attention to the gap between rough and finish machining, and must be buffered for a period of time. This is to make the deformation of parts after rough machining fully recover time, and then finish machining after recovery, which can improve the machining accuracy of parts and increase the qualified rate of finished products.Line Cutting

What are the principles for handling precision machined parts? What are the safety precautions when processing precision parts?CNC Lathe
1.Processing principles of precision machining
There are three specific processing principles for precision machining, as follows.
(1) In order to ensure machining accuracy, roughing and finishing are best carried out separately. Because rough machining, cutting volume, the workpiece is subject to cutting force, clamping force, more heat, as well as the processing surface has a more significant machining hardening phenomenon, there is a large internal stress inside the workpiece, if rough, rough machining is carried out continuously, the precision of the parts after finishing will be quickly lost because of the redistribution of stress. For some parts with high machining accuracy requirements. After roughing and before finishing, should also arrange low-temperature annealing or aging treatment process to eliminate internal stress.Sheet Metal
(2) reasonable choice of equipment. Roughing is mainly cut off most of the machining allowance, and does not require a high degree of machining accuracy, so roughing should be in the power, accuracy is not too high on the machine tool, finishing process requires a higher precision machine tool processing. Rough and finish machining in different machine tools, not only can give full play to the capacity of the equipment, but also to extend the service life of precision machine tools.
