Further, before step S1 is performed, the positional relationship among the connecting member 51, the driving shaft 42 and the sliding seat 4311 needs to be adjusted, specifically, the positions among the connecting member 51, the driving shaft 42 and the sliding seat 4311 are adjusted by adjusting the screwing lengths of the first adjusting screw thread and the second adjusting screw thread, so that the positioning assembly 5 and the supporting member 431 are correspondingly limited at the polishing position 113 and the drilling position 114.
The valve ball machining process provided by the embodiment of the invention has all the beneficial effects of the valve ball machining device because the valve ball machining device is adopted, is simple to operate, is accurate in positioning, and can effectively improve the polishing effect and the drilling accuracy.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
