Polishing is a common surface treatment process, which mainly plays the following roles:
Improving surface smoothness: Polishing can remove burrs, unevenness, and small scratches on the surface of the workpiece, making the surface smoother. By polishing, the surface smoothness of the workpiece can be improved, giving it a better appearance and texture.
Improving surface quality: Polishing can improve the quality of the workpiece surface, remove harmful substances such as oxide layers, rust, and stains, and present a more uniform, clean, and bright state on the workpiece surface. This helps to improve the corrosion resistance and service life of the workpiece.
Increase glossiness: Polishing can increase the glossiness of the workpiece surface, giving it a mirror like effect. By using different polishing processes and materials, the glossiness of the workpiece surface can be adjusted to meet different needs.
Improving lubrication performance: Polishing can form a smooth film on the surface of the workpiece, improving the contact friction between the workpiece and other components. This helps to reduce friction coefficient, improve lubrication performance, and reduce energy loss and wear.
Repair and repair: Polishing can repair and repair defects and damages on the surface of workpieces, such as scratches, wear, and oxidation. By using appropriate polishing techniques and tools, the surface of the workpiece can be restored to a flat, smooth, and flawless state.
Polishing plays an important role in industrial processing, which can improve the smoothness, quality, and glossiness of the workpiece surface, improve lubrication performance, and repair and repair surface defects. This helps to improve the quality and value of the product, meeting the requirements of different industries for the surface of the workpiece.
Grinding wheel
Grinding wheel is a commonly used grinding tool, widely used in polishing work in industrial processing. The following are the general steps for polishing with grinding wheels:
Choose a suitable grinding wheel: Based on the material to be polished and processing requirements, choose a suitable grinding wheel. The types and particle sizes of grinding wheels are different, suitable for different materials and processing effects.
Installation of grinding wheel: Install the selected grinding wheel onto the grinder or polishing machine. Ensure that the grinding wheel is firmly installed, has good balance, and can rotate normally.
Adjusting the position of the workbench and grinding wheel: Adjust the position of the workbench and grinding wheel according to the processing requirements. The height and tilt angle of the workbench can affect the polishing effect.
Preparation of workpiece: Prepare the workpiece to be polished. Clean the surface of the workpiece to ensure that it is free of impurities and dirt.
Apply polishing agent: Apply appropriate polishing agent to the surface of the workpiece as needed. Polishing agents can provide lubrication and cooling effects, while improving the polishing effect.
Start polishing: Start the grinder or polishing machine to start polishing work. Slowly move the workpiece onto the grinding wheel, maintaining appropriate pressure and speed. Pay attention to the angle and direction of the workpiece to achieve the desired polishing effect.
Continuous polishing: Continue polishing until the expected polishing effect is achieved. As needed, multiple polishing can be carried out, using grinding wheels with different particle sizes to gradually improve the precision and smoothness of polishing.
Clean the workpiece: After polishing, clean the surface of the workpiece to remove polishing agent and grinding wheel residue. Ensure that the surface of the workpiece is clean and smooth.
