Blog #abrasive grinding disc tools

In the abrasive grinding disc tools, in order to increase its safety factor, some details must be paid attention to. Before starting to use the grinding tool, please use it for one minute and then use it. When replacing the new type of grinding tool, please idle for 3 minutes before using ; use an angle grinder with safety cover, cutting machine with safety cover.

Users must wear protective glasses, masks, earplugs, gloves, dust-proof clothing, etc., take protective measures, keep the abrasive grinding disc tools in a place without direct sunlight, no moisture, and place them horizontally; if you encounter the inner diameter of the abrasive grinding disc tools When the small and the equipment do not match, please do not change the diameter of the grinding tool. Use the highest speed of the ultra-thin resin cutting piece and use the maximum number of revolutions.

The knowledge about abrasive grinding disc tools is introduced here. If you want to know more, you can pay attention to Henan Aurora Abrasive Tool Co., Ltd., we specialize in grinding wheel cutting and grinding tools production and business. Welcometo buy.

  The quality of diamond depressed grinding disc for metal is one of the important factors that can improve the processing productivity and surface quality of the products. Therefore, in high-end CNC machining centers, a high-efficiency composite tool can be used to replace multiple single-function tools, and it can automatically process complex-shaped workpieces according to the machining program, thus improving production efficiency. , surface quality and reduced production costs play a very good effect.

  It is reported that the use of advanced and efficient abrasive grinding disc tools can significantly improve the cutting efficiency, and the increase in tool costs is far less than the decline in production costs. At the same time, advanced and efficient tools can effectively reduce various benefits such as tool change time and product quality. Therefore, considering the comprehensive consideration, the use of advanced and efficient tools is very effective in improving processing efficiency and reducing the production cost. Research and development and application of new advanced and abrasive grinding disc tools are one of the development trends of machining in the future.

  Then, when grinding the high-efficiency tool, when the material, structure, and shape of the tool and the selection of the grinding machine are all determined, the diamond grinding disc becomes an important factor in determining the success or failure of the machining. The technical content of the depressed grinding disc for metal and the quality of the depressed grinding disc for metal also determine whether it can produce high-quality abrasive grinding disc tools that meet the design requirements.

  When it comes to diamond depressed grinding disc for metal, although the processing efficiency of ultra-high temperature resin bond diamond grinding discs is lower than that of METROX grinding discs, the bonding strength of diamond grinding discs is high, the production cycle is short, and the processing cost is low, especially when grinding the cutting edge of the tool. In the case of chipping, it can also be ground into various shaped grinding wheels according to the requirements of use. Therefore, diamond grinding discs are still widely used in production.

You know the size of abrasive grinding disc tools.

Abrasives are not only widely used in mechanical manufacturing and other metal processing industries, but also used in grain processing, paper industry and ceramics, etc. It is more widely used, so we should pay attention to its particle size after the meeting in this respect, today to understand this aspect.

Grain size refers to the size of abrasive particles, and the size is represented by grain size. The national standard specifies two sizes of abrasive and micro powder.

Particle size refers to the size of abrasive particles. Granularity is divided into two categories: abrasive and micro powder. For abrasive particles with large particle size and large cylindrical grinding wheel at 40 m, they are called abrasive particles. The size number is expressed by the number of holes in each inch of the screen passing through the grit. The size of the 60 abrasive grain indicates that the size of it can pass through 60 mesh holes per inch. For abrasive particles with a particle size less than 40 m, they are called fine powders. Grading by microscopic measurement, the size number is expressed by W and the number after W, and the value after W represents the actual size of fine powder. For example, W20 indicates that the actual size of the powder is 20 m.

In short, from the above content can be seen, abrasives in use to pay attention to the corresponding problems, each particle size is different, so in this respect at the same time pay attention to the corresponding information, so that you can choose according to your own situation.

Are you looking for 4 inches China grinding disc factory or China grinding disc manufacturer? We are the manufacturers you are looking for.

Grinding wheel is a kind of abrasive grinding disc tools with a large amount of usage and scope, so we are more concerned about its life, in addition to normal wear, there are other reasons leading to this phenomenon, to understand these factors, can also extend the service life.

The grinding wheel is made of abrasive and binder. Because the friction between the grinding wheel and the grinded workpiece produces a great deal of heat, the binder is easy to be softened.

The depressed grinding disc for metal is a bit blunt after a long time of hard work, which is mainly due to the friction between the surface particles and the tool, will gradually wear blunt, when the grinding resistance exceeds the bonding force between the particles and binder, the particles began to fall off, and was replaced by new sharp particles.

The grinding metal material and the binding agent are adhered to the gap between the sand grains, and the wheels are solid. If this kind of stopper grinding wheel continues to work, not only the work efficiency is quite low, the China abrasive tools for metal will become blue and cause annealing.

On the other hand, if the binder can not bond the particles firmly, grinding between the particles has not become pure will make them fall off, so that the sand transmission line wear fast, easy to deformation, need to be regularly trimmed.

These four conditions are the key to the life of the grinding wheel, which should be paid special attention to in daily use.
