In precision grinding processes, diamond grinding wheels are widely used due to their extremely high hardness. However, as the usage time increases, the grinding wheels may experience problems such as abrasive particle wear and shape deviation, which directly affect the processing quality. How to scientifically select and correctly operate the diamond grinding wheel forming and dressing machine has become the key for enterprises to improve processing accuracy.
1. Why does a grinding wheel need to be "polished"?
During the use of diamond grinding wheels, the abrasive grains will gradually wear out, become blunt, and even fall off. Forming and finishing involve two processes:
Polishing: Restoring the geometric shape and runout accuracy of the grinding wheel
Xiu Rui: Reveals new sharp abrasive particles, ensuring cutting ability
Only through proper adjustment can the grinding wheel regain its optimal performance, ensuring the accuracy and efficiency of subsequent grinding operations.
II. How to Select the Appropriate Shaping Machine?
The diamond grinding wheel forming and dressing machine is a type of CNC
Roller Ring Grinding Machine. When making a selection, enterprises should focus on the following three aspects:
Clarify processing requirements
For precision molds, aviation parts and other items that require micro-metric precision processing, CNC finishing machines should be selected; for general processing, ordinary models can be chosen.
Evaluate equipment performance
The spindle runout of the high-precision finishing machine should be less than 0.002mm, and the feed control accuracy should reach 0.001mm. Only in this way can the requirements for the finishing of complex forming surfaces be met.
Selecting an appropriate repair method
Numerical control forming and finishing: The highest precision, suitable for complex surfaces and various small-batch types.
Diamond roller dressing: The most efficient, suitable for mass production.
Trajectory formation and finishing: Low cost, suitable for non-batch and complex-shaped surfaces
