The arrangement of processing sequence should be considered based on the structure of the parts and the condition of the blank, as well as the need for positioning and clamping, with the focus on ensuring that the rigidity of the workpiece is not damaged. The sequence should generally follow the following principles: the CNC machining of the previous process should not affect the positioning and clamping of the next process, and if there are general machine tool machining processes interspersed in the middle, comprehensive consideration should also be given.

The division of CNC machining processes can generally be carried out according to the following methods: the centralized tool sorting method is to divide the processes according to the used tools, and use the same tool to CNC machine all the parts that can be completed. Using the second and third knives to complete other parts that they can complete. This can reduce the number of tool changes, compress the idle time, and reduce unnecessary positioning errors.

Traditional mechanical processing is done by manually operating ordinary machine tools. During processing, the mechanical tools are shaken by hand to cut metal, and the accuracy of the product is measured using tools such as calipers with the eyes. Modern industry has long used computer digitally controlled machine tools for operations, and CNC machine tools can automatically process any product and component according to pre programmed programs by technicians. This is what we call "CNC machining". CNC machining is widely used in any field of mechanical processing, and it is also a development trend and an important and necessary technical means for mold processing.

Firstly, the injection pressure should be greater than 25MPa; Injection speed greater than or equal to 300mm/s; The dimensional accuracy of the product is 0.001mm; The coefficient of standard deviation (rate of change) of product quality is less than 0.1%; Precision of opening and closing positions: opening ≤ 0.03mm, closing ≤ 0.01; The injection position accuracy (pressure maintaining end point) is less than 0.03mm; The force balance of the pull rod is less than 1%; The precision of the pre molded position is less than 0.03mm; Balance degree A of fixed and dynamic templates: less than 0.03mm when the locking force is zero; B: less than 0.005mm when the locking force is greater than z; The temperature control accuracy of the barrel and screw is less than ± 0.5 ℃.

During the forming and punching process of precision stamping parts, due to external factors such as strength, the knife can be split in one step. When dividing the knife, it is particularly important to pay attention to the functional stability of the coil material, which requires uniform stress and a common strength of the coil material

The quality of precision component processing products is always a concern for us at all times. Ensuring the quality of stamping parts processing is a necessary task. In a highly competitive society, we can better ensure the quality of precision hardware stamping parts processing, allowing customers to receive better assurance. As a stamping parts manufacturer, we must ensure the quality of all aspects.
