Nest bead machine: put the nearly round jade beads grinded by setting machine or manually adding water into the nest bead grinding head to rub back and forth. It can also be used for different grinding heads, and it only needs to reach the required roundness diameter after a certain period of time. If there is no flat knitting machine, if the bench drill can hold the grinding head, it is also very useful to put a small bucket below.
Production method:
The polishing of beeswax beads still needs some professional equipment: punching machine, Korean new tooth machine, bead nest, PCB drill, cake, sandpaper, strong flashlight, caliper, jewelry scale, wire saw, dust mask and dust eye mask. Choose beads here to remind parents that round beads are polished and decorated with basic square squares.
If you want to grind a 20 mm ball, then you need to use it. The length, width and height must be more than 22mm, so that round beads of about 20 mm can be ground. There is also a premise that the original beeswax stone does not have any cracks. A process of polishing beeswax beads. The second step is the transformation of rough embryo. Coarse embryo modification: thoroughly polish the skin of the original beeswax stone with 60 mesh and 220 mesh sandpaper or bench drill+cake.
Pay attention to three points here. First, everyone must dip in water when polishing to prevent beeswax from cracking due to excessive temperature. Second, leather must be thoroughly polished. Third, measure the size with calipers when grinding to prevent accidental wear. A process of polishing beeswax beads. The third step is to modify excellent embryos with a ball and socket device.
This is an important step in grinding round beads. It is difficult to achieve a perfect circle simply by sandpaper polishing, so we need to use the "ball and socket device" to assist in rounding. First, install the tee on the bench drill. Adjust the speed to the lowest, then pinch the beeswax stone with your fingers and adjust it with the speed and frequency of machine rotation.
