During Stainless Steel Electrolysis polishing, workpiece deformation is a possible problem, which is mainly caused by factors such as excessively high electrolyte temperature, complex workpiece shape, or long electrolysis time. The following are several key measures to avoid workpiece deformation:
1. Control electrolyte temperature
During the electrolytic polishing process, the temperature of the electrolyte has an important influence on the polishing effect and workpiece deformation. Excessive temperature may cause uneven heating of the workpiece, causing deformation. Therefore, appropriate cooling measures need to be taken, such as using a refrigerator to cool the electrolyte to ensure that the electrolyte temperature is controlled within a suitable range. It is usually recommended to maintain it between room temperature and 40 degrees Celsius.
2. Select workpieces with simple shapes
The complexity of the workpiece shape is also a factor that causes deformation. Complex shapes may cause uneven current distribution, causing the workpiece to be subjected to uneven forces during polishing, resulting in deformation. Therefore, when selecting workpieces, try to choose workpieces with simple shapes and symmetrical structures to reduce the risk of deformation.
3. Shorten the electrolysis time
Excessive electrolysis time is also a reason for workpiece deformation. Long-term electrolysis may cause excessive dissolution of the workpiece surface, causing deformation. Therefore, during the electrolytic polishing process, the electrolysis time should be reasonably set according to factors such as the material, size and polishing requirements of the workpiece to avoid excessive electrolysis time.
4. Adjust the current density
The magnitude of the current density will also affect the deformation of the workpiece. Excessive current density may cause local overheating on the surface of the workpiece, causing deformation. Therefore, during the electrolytic polishing process, the current density should be reasonably adjusted according to factors such as the material and size of the workpiece to ensure that the current density is within the appropriate range.
5. Use appropriate fixtures and protective covers
During the electrolytic polishing process, the use of appropriate fixtures and protective covers can effectively reduce the risk of workpiece deformation. The fixture should be able to stably fix the workpiece to prevent it from moving or rotating during the polishing process. The protective cover can reduce the direct impact of the electrolyte on the workpiece and reduce the possibility of workpiece deformation.
In summary, by controlling the electrolyte temperature, selecting a simple-shaped workpiece, shortening the electrolysis time, adjusting the current density, and using appropriate fixtures and protective covers, the Stainless Steel Electrolysis polishing process can be effectively avoided.
