How to make Beauties of Nature Flower Opening/Closing Mechanism (Pillar Ball Screw)
This is a ball screw for the tip that attaches to the support column. It's shaped like the tip of a ballpoint pen, and the process involves cutting, drilling, threading, heat treatment, and tempering.
The tempered part is then mounted back on the lathe, and a groove for the ball is drilled using an end mill. The groove is then tapered towards the tip, and the ball is fitted into place.
Since the ball is loose when it's just fitted in, use a burnisher to bend the tip so that the ball doesn't fall out and can rotate freely within the groove. Finally, attach it to the support column and check the ball's rotation to complete the process.
