Through the analysis of the sectional drawing of the pneumatic ball valve shell, the most ideal method for machining the inner surface of the part is turning. Because it is difficult to ensure the dimensional accuracy and surface quality of spherical surface by manual turning with ordinary lathe, it is difficult to achieve good surface contact when matching with other parts, so CNC turning must be adopted to ensure the processing accuracy. Since the inner surface of the valve body is approximately a closed sphere, it is inconvenient for the tool to enter and exit during machining. If the ordinary wok cutter is used for processing, it is difficult to ensure its rigidity because the overhang length of the cutter bar exceeds 75mm. Therefore, reasonable tool design is the key step to realize machining.

When people can understand the electric three-way ball valve with an ideal attitude in life, they can have a more ideal understanding of each part of various products. In order to make the equipment operate better, after knowing the actual parameters, the overall operation mode should also be better mastered, so that the equipment can enter a more ideal working state.
