Among the complicated automatic polishing machines, 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 browsed through all the previous mechanical introductions and found that there are still omissions. I do not seek perfection, but only want to share what I know as much as possible. This omission is the category of small products, such as small accessories and small metal objects. Because the products are too small and large in quantity, manual polishing is unlikely, and only mechanical processing can be sought.
We introduce that there are two main types of machining methods for such products: one is a flat polishing method; the other is a cambered polishing method.
Flat polishing method. This kind of polishing method does not mean that it is only suitable for completely flat products. Due to the small size of small products, the overall size may be only one or two centimeters. Therefore, these flat products or products that are close to flat can also be polished by the flat product polishing method. polishing effect. Our common mobile phone pins are petite in size and belong to pure flat products. We only need to use a flat polishing machine to customize a pin that can accommodate dozens or even hundreds of pins at the same time, thereby improving efficiency. In addition, keychains, hair accessories, accessories, etc. may not be purely flat, and the products have a certain radian, but due to the small radian and small size, we can use the same flat polishing machine for processing. It is only necessary to pay attention to the use of the polishing wheel. During the initial polishing, a hemp rope wheel can be used, and a softer polishing wheel can be used for fine polishing or fine polishing, so that the polishing wheel can contact some non-planar grooves.
Curved surface polishing method. This type of cambered product refers to a category that is small but has a very large appearance, such as small objects such as bracelets, rings, and half rings. Such products can no longer be simply polished by plane, and some difficult ones even require CNC polishing. For small products such as semi-rings, it can be solved by simple single-axis numerical control, so that the polishing wheel can automatically adjust the stroke along the semi-circular arc for polishing. For ring-shaped products such as rings and bracelets, a fixture needs to be designed to drive the product to rotate. The principle is similar to that of a double-sided circular tube polishing machine. This method can solve the 360-degree non-dead-angle polishing of the ring, and it can also be used in series. Simultaneously process a large number of workpieces with high efficiency.
