Jewelry OEM punching inlay skills

When jewelry is made, in addition to the role of shape, cutting and grinding, inlaid jewelry is also very important. Most of the pendants, ear studs, and bracelets that are generally seen need to be embedded. The drill position, size, and quality will affect the quality of the jewelry. So, what tools do you need for a hand drill? Today KeKe Jewelry Manufacturer brings you a jewelry drilling tutorial, friends who like it, come and have a look!

The most important rule for drilling is to determine if the drilling position is correct. It's not as simple as it sounds. Before you start using it, you have to think about where to drill the holes.

First, mark the drilling location.

Before punching, mark the best position. Use a center punch mark with a spring, or use a scribing tool to draw the point to be drilled, and choose one based on the size to be drilled and the thickness of the metal.

When using the scriber, place it on the metal surface evenly with your hand, then move it quickly from side to side. If a center punch is used, the drill should be placed on a flat metal, and then the center punch should be placed on the workpiece and pushed down smoothly. The impact of the center punch is great, so there will always be some metal shavings around. But it doesn't matter if the drilling is very large.

The second is drilling technology.

When drilling, tighten the workpiece. If moving, rotate quickly with the drill bit. Well location is another important consideration. Drilling large areas of non-cutting metal is much easier than drilling precise holes in neat, small workpieces. If a hole is to be made in the center, it is generally easier to cut around it. In general, the workpiece on the table should be placed in the hand. However, metal that is drilled with a hand-held crane or electronically can get very hot while drilling. That way, applications can clamp a piece of wood to a piece of wood, or drop the drill bit into oil or water to cool it down during a run. If you want to drill large holes, you can drill small holes first, and then gradually enlarge, so the operation is easier.

The third is drilling tools.

Second, there are four different hand-held needle drills.

Jewelry surface punching process

Do not drill directly on the curved surface, as the drill bit will not be able to grasp it, and it is easy to slip around or even break during operation. Usually, file a small face at the top of the curved surface, mark the drilling position with a pencil, and then mark the drilling with a scriber.

make small drills

There are some small holes that can be made with needle and thread. Use flat-nose pliers to clamp the needle tip at the end of the needle, then clamp the needle tip with a vise, and then clamp 1/3 of the needle with a vise, fold one end on the oiled diamond sandstone, and make a wedge of about 45 degrees at the other end. Gently remove opposite sides and grind into double wedges. Using this method to make small drill bits is very practical and strong, but it is not suitable for metal thicknesses greater than 1mm (1/32).
