1、 Application of polishing wheel of stone polishing machine
There is no doubt that polishing wheel plays an important role in the whole polishing process. No matter how the surface is treated, it should be used to complete the surface treatment. Grinding, peeling, deburring, polishing, mirror polishing, etc. Because of its importance, the problem is more prominent.
1. Select polishing wheels according to different polishing materials, and use different polishing wheels for different metals. For example, hemp or hemp wheel can be used for initial polishing of stainless steel. The hardness of hemp wheel should be large enough to achieve the polishing effect of stainless steel surface. You can't use this super hard polishing wheel for copper. Copper is too soft, polishing wheel is too hard, easy to deformation. At present, wind turbine has been widely used.
2. The polishing wheel is selected according to the polishing requirements. As mentioned above, different degrees of polishing are required, such as grinding, polishing, mirror polishing, etc. Abrasive belt and 1000 impeller are usually used for grinding, but sponge and hemp wheel can also be used in some cases. The grinding effect adopts hemp rope wheel, hemp wheel and 1000 wire wheel. Cloth wheel is generally used for stainless steel with mirror effect, soft can use pearl cloth wheel.
2、 Use polishing wax
If the polishing wheel is used to dry grind the product, it will only damage the product. Therefore, the chemical polishing wax (polishing paste) needs to be applied on the polishing wheel at the same time. The use of polishing usually depends on the polishing effect and the material of the polishing product. In the polishing process, white wax is generally used for stainless steel, yellow or red wax is used for zinc alloy and aluminum alloy, and purple or blue wax can be applied for 304 stainless steel. For fine polishing, green wax is usually used, but white wax is used if more is needed.
3、 Fixture problem
In the process of stone polishing machine, we often encounter the problem of product fixation. There are many products in the polishing industry. In addition to the common pipe, square tube, plate and other products, there are also standard mechanical polishing. Some irregular or small products need to be fixed before polishing. The fixture used to fix the product is called fixture in polishing device. Usually fixed on the machine workbench, mainly including vacuum cleaner fixture, electromagnetic cleaner fixture and universal fixture. In the polishing process of irregular products, if the fixture is not installed, it may cause scattering, which is the attention in the production of stone polishing machine. How to customize the appropriate fixture will seriously affect the polishing efficiency. For example, when the flat polishing machine is used for small flat products, it is necessary to install a fixed device on the worktable of the flat polishing machine. Generally speaking, vacuum cleaners can be used for aircraft products, while electromagnetic cleaners can be used for iron products. However, fixture manufacturing usually needs to customize the shape of polished products. In the design process of stone polishing machine, we need to coordinate as much as possible to ensure that the fixture is suitable for the machine and products.
