  • Patent number: 12275080
    Abstract: A tapping apparatus adapted for tapping a workpiece includes a lower die unit to drive the workpiece to move along a conveying direction, and an upper die unit disposed above and movable upwardly and downwardly relative to the lower die unit. A tapping mechanism is disposed between the lower and upper die units to be driven by the upper die unit for tapping the workpiece so that the workpiece is formed with a tapped hole. A thread checking mechanism is disposed between the lower and upper die units and is spaced apart from the tapping mechanism along the conveying direction. The thread checking mechanism is driven by the upper die unit for checking the tapped hole of the workpiece.

  • Publication number: 20240123567
    Abstract: A double-sided polishing method for an optical lens belongs to the technical field of ultra-precision machining. In the double-sided polishing method, upper and lower surfaces of the lens are polished simultaneously by arranging abrasive tools on upper and lower positions of the lens, making the abrasive tools close to the upper and lower surfaces of the lens to swing back and forth in the polishing process, producing relative motion and removing the surface materials. In the present invention, in order to eliminate a problem of removal ununiformity, a method for swing machining of abrasive tools and methods for turning over and polishing of workpieces are adopted in a polishing process, which can realize the high efficiency double-sided high-precision machining for a nonplanar lens, and the method can be applied to the double-sided polishing for different types of lenses.
