What’s the use of hollow alumina balls in grinding wheels？
Improve the density and grinding effect of the grinding wheel: hollow alumina ball have a high porosity and a smooth surface, which can fill the gaps in the grinding wheel, thereby improving the density of the grinding wheel. This increase in density helps the grinding wheel maintain stable grinding performance during use, is less likely to wear, and thus extends the service life of the grinding wheel. At the same time, due to its high hardness, alumina hollow balls can generate higher grinding force when grinding objects, significantly improving the grinding effect.
Heat dissipation and heat insulation effect: The grinding wheel will generate a lot of heat during the grinding process. If it cannot be dissipated in time, the temperature of the grinding wheel will rise, which will affect its service life and grinding effect. Alumina hollow balls have a unique hollow structure, which can play a good role in heat dissipation and heat insulation, effectively reduce the heat loss of the grinding wheel, and keep the temperature of the grinding wheel stable during the grinding process, thereby extending the service life of the grinding wheel and improving the grinding efficiency. quality.
Optimize grinding wheel structure and performance: hollow alumina balls are used as filling materials for grinding wheels and can also play a role in making holes. These pores can quickly take away the heat generated by grinding during the grinding process, further improving the sharpness of the grinding wheel and reducing burning on the workpiece surface. At the same time, the presence of pores also helps to improve the structure of the grinding wheel, making it more uniform and stable, thereby improving the overall performance of the grinding wheel.
Enhance the strength and hardness of the grinding wheel: The high hardness of the hollow alumina balls enables it to enhance the strength and hardness of the grinding wheel, making the grinding wheel more wear-resistant and able to work longer.
Reduce production costs: Since alumina hollow balls have high wear resistance and grinding efficiency, the frequency of tool replacement and grinding time can be reduced, thereby reducing production costs.
