1. The mechanism of the effect of linear speed on sand milling efficiency
1. Grinding force distribution: The change of linear speed will affect the grinding force distribution between the sand milling medium and the workpiece. When the linear speed increases, the grinding force will increase accordingly, making the grinding process more intense and helping to remove the material on the surface of the workpiece. However, too high a linear speed may cause excessive grinding force, excessive damage to the workpiece surface, and even affect the performance of the workpiece.
2. Grinding temperature: The increase in linear speed will increase the temperature during the grinding process. Appropriate grinding temperature helps to promote material removal and improve surface quality. However, too high a grinding temperature may cause problems such as burns and thermal stress on the workpiece surface, reducing the efficiency of sand milling.
3. Sand milling medium wear: The increase in linear speed will accelerate the wear of the sand milling medium. Although wear is an inevitable phenomenon in the sand milling process, excessive wear will cause the sand milling medium to lose its original shape and sharpness, reduce its grinding ability, and thus affect the efficiency of sand milling.
2. Line speed optimization and sanding efficiency improvement
In order to give full play to the performance of the sand mill and improve the efficiency of sanding, we need to optimize the line speed of the sand mill. Here are some suggestions:
1. Reasonable selection of sanding media: Select appropriate sanding media according to the workpiece material and processing requirements. The maximum line speed under different materials and processing requirements may be different, so it needs to be adjusted according to the actual situation.
2. Control the motor speed: The motor speed is one of the key factors affecting the line speed of the sand mill. By adjusting the motor speed, we can control the line speed of the sanding medium, thereby achieving a balance between grinding force, grinding temperature and sanding medium wear.
3. Cooling and lubrication: In order to reduce the grinding temperature and reduce the wear of the sanding medium, coolant or lubricant can be added during the sanding process. These liquids can effectively reduce the grinding temperature and reduce the wear of the sanding medium, thereby improving the sanding efficiency.
4. Sanding medium maintenance and replacement: Regularly check the wear of the sanding medium and replace the severely worn sanding medium in time. In addition, proper maintenance and care of the sanding medium can also help to improve its service life and grinding ability.
