The standard of precision CNC parts industry is very strict. There are different processes such as tool feeding and tool discharging during processing. The size will also vary according to the specific requirements of the product, and the requirements for processing accuracy will also vary. In general, the requirements for precision processing accuracy are very high, sometimes even to the number of micrometers below 1mm. If the size difference is large, the product will become a waste product, and it needs to be reworked to meet the requirements. This process is very time-consuming and laborious, and sometimes all raw materials will be scrapped, resulting in increased costs, At the same time, CNC is bound to be unusable, so there are many requirements for precision CNC machining. What are the requirements for precision CNC machining?
(1) Generally, in order to ensure the machining accuracy of parts, rough machining and precision mechanical CNC machining must be operated separately, because the cutting amount, clamping force, heat generation and cutting force of the workpiece are different between rough machining and precision CNC machining. If rough machining and precision machining are carried out continuously, the precision of precision CNC machining will be lost due to different stresses.
(2) Rationality of equipment selection. Rough machining does not require high machining accuracy, but mainly for machining allowance cutting, so precision CNC machining requires very high precision machine tools.
(3) In the process of precision CNC machining, heat treatment is often arranged. The position of heat treatment process is arranged as follows: In order to improve the cutting performance of metal, such as annealing, normalizing, quenching and tempering, it is generally arranged before mechanical CNC processing.
(4) Generally speaking, precision CNC machining almost has a heat treatment process, which can improve the metal cutting performance.
