The cause and solution of burr in grinding process (2)

The processing conditions in the grinding process also influence the generation of burrs. The following is a detailed analysis from the processing speed, grinding fluid, feeding mode and machine structure.

Processing speed: The higher the grinding speed, the shorter the contact time between the grinding wheel and the workpiece, which reduces the generation of grinding heat, thereby reducing the surface temperature of the workpiece, which is conducive to reducing the generation of burrs. However, too high grinding speed will lead to increased grinding wheel wear, so it is necessary to choose a suitable grinding speed.

Coolant: Coolant can play a cooling, lubrication and cleaning role, reducing the temperature of the grinding zone, reducing the surface of the workpiece burrs. At the same time, the grinding fluid can also remove the grinding chips and fine particles in time to prevent the generation of secondary cutting and scratches.

Feeding mode: Improper feeding mode leads to excessive overlap between the grinding wheel and the workpiece, resulting in excessive heat and stress, which leads to the generation of burrs. Therefore, the appropriate feeding method and feeding amount should be selected to ensure the stability and accuracy of the grinding process.

Machine structure: The rigidity and vibration stability of the machine structure also have an impact on the generation of burrs. The better the rigidity and the smaller the vibration of the machine, the more conducive to reducing the generation of burrs.
