With the increasing number of machinery industry, more mechanical products need to be processed. Typically, each product processing needs to be formed by cutting wheels, followed by subsequent grinding and polishing, and through a series of processes to become a mature product. It is undeniable that the quality of cutting sheet products on the market is uneven: "cutting wheel is not durable", "cutting wheel cutting efficiency is very low", "cutting wheel safety accidents" and so on. Today, we will share with you the product considerations and the principles of selecting cutting pieces. First of all, good uniformity and no cracks are the basic appearance of high-quality grinding wheels. Secondly, fine packaging printing anti-counterfeiting bar codes are the difference between original products and counterfeit products. Finally, how to choose safe, efficient and wear-resistant cutting products! The following abrasives cutting experts introduce you to several priority factors in the selection process:
1. When grinding high tensile strength materials, choose abrasives with high toughness.
2. Brittle abrasives should be selected for materials with low grinding hardness and high elongation.
3. When grinding high-hardness materials, choose abrasives with higher hardness.
4, choose abrasives that are not easy to process.
5, when the hardness of the material processed is higher or the cutting area of the material is larger, a sharp grinding wheel with a looser organization should be selected, so as to effectively improve the processing efficiency.
6, when the hardness of the material processed is low or the cutting area of the material is small, the durable grinding wheel with a tighter organization should be selected, so as to effectively improve the service life of the grinding wheel
7, when the use of electric or pneumatic tools for a long time, wear or insufficient power, should choose should choose the organization of the looser sharp grinding wheel, to avoid cutting or grinding and other processing difficulties.
8, when the power of electric or pneumatic tools is large, the grinding wheel with sufficient strength should be selected. Under no circumstances is it allowed to exceed the maximum safe speed of the grinding wheel.
9, under special processing conditions, you can find Yi Lida abrasive manufacturers for customized processing and production.
In addition, what is the cause of the sudden rupture of the cutting wheel ?
We all know that in the process of manufacturing and using cutting wheels, we often find that the cutting pieces are broken, how to avoid it? Then pay attention to the following questions:
1. Before installing the fan, check whether the resin grinding wheel has cracks, and tap the grinding wheel with a wooden hammer to see if there is an abnormally quiet sound. If yes, the cooling fan cannot be used for cutting to avoid damage or injury caused by the grinding wheel rupture.
2, the resin grinding wheel used every other day or every other day should be idled for more than one minute before use. If all is in order, it can be used in accordance with the relevant safety regulations for grinding machinery.
3, because the resin grinding wheel is fragile and brittle, please do not let it impact, collision or fall alone. When stored, it should be frost-proof, moisture-proof, ventilated and cool, placed smoothly, stacked neatly, dustproof, and keep unused grinding wheels clean and free from heavy pressure.
4. When installing the resin grinding wheel, you must find the center of the resin grinding wheel and tighten the flange at the same time. After installing the flange, check whether the outer ring of the grinding wheel is concentric with the spindle. At least one side of the resin grinding wheel is perpendicular to the center line of the spindle.
5, after the installation of resin grinding wheel, for safety reasons, do not install unqualified protective cover. Then start the machine.
In short, when choosing cutting wheels , we must ask professional personnel for reference to buy high-quality and inexpensive products.
