Small product categories, such as small jewelry, small metal objects, because the product is too small and large, manual polishing is not likely, can only seek metal jewelry polishing machine, we have introduced most of the types, high degree of automation , low degree of automation, square tube polishing, round tube polishing, flat polishing, and so on. I have browsed all the previous mechanical categories and found that there are still some omissions. I don't want to be perfect, I just want to share the knowledge as much as possible. This omission is a small product category, such as small jewelry, small metal objects, because the product is too small and large, manual polishing is not likely, can only seek mechanical processing. We introduce two main types of machining methods: one is a flat polishing method; the other is a curved surface polishing method.
Plane polishing method. This kind of polishing method does not mean that it is only suitable for a completely flat product. Because the small product is small in size, the overall size may be one or two centimeters. Therefore, these flat or near-planar products can also be expected by flat product polishing. Polishing effect. Our common mobile phone card pin, which is petite and small, is a purely flat product. It only needs to use a flat polishing machine to customize one that can accommodate dozens or even hundreds of card pins at the same time for polishing, thereby improving efficiency. In addition, like keychains, hair accessories, accessories, etc. may not be purely flat, the product has a certain degree of curvature, but due to the small curvature and small size, we can use the same plane polishing machine for processing. It is only necessary to pay attention to the use of the polishing wheel. When the first throw is used, the hemp rope can be used, and the soft polishing wheel can be used for fine throwing or fine polishing, so that the polishing wheel can contact some non-planar grooves.
Arc surface polishing method. This kind of curved surface product refers to a small type of product, such as bracelets, rings, semi-rings, etc., although the product is small but the curvature of the appearance is really large. Such products have been unable to simply use flat-type polishing, and some of the more difficult ones even require CNC polishing. For a small semi-annular product, it can be solved by simple single-axis numerical control, and the polishing wheel is automatically adjusted along the semi-circular arc for polishing. The ring and bracelet circular ring products need to be designed to drive the product to rotate. The principle is similar to the double-sided round tube polishing machine. This method can solve the ring shape of 360 degrees without dead angle polishing, and can also be connected by series. Processing a large number of workpieces at the same time is extremely efficient.
By categorizing different products and then matching different polishing methods, we have already shared most of the industry products. Such sharing will come to an end and some missing types may be added later. To sum up, during this time, we mainly shared various polishing processes, polishing methods, mechanical equipment "target=_blank> matching of mechanical equipment, consumables use, etc., and the industry knowledge involved is relatively broad, I hope everyone will gain something. In the final stage, I would like to thank Nie Wen and Xu Hui, the automatic polishing machine experts who provide technical support for this series, polishing technician Tang Hong, polishing consumables expert Shi Changjin, etc. These professionals who have been immersed in the polishing industry for many years, share without reservation. I know what I have learned.
