What are the precautions for grinding and polishing of aluminum alloy saw blades

Aluminum alloy saw blades are used for cutting, sawing, milling, and grooving aluminum alloy materials. They are hard alloy toothed circular saw blades that are immersed in abrasive grinding fluids and can be pressed tightly against the workpiece and rotate at high speeds during processing.

1. It is necessary to polish and polish under light pressure, especially when polishing pre-hardened steel parts and using fine abrasive pastes. When using #8000 abrasive paste for polishing, the common load is 100-200g/cm2, but it is difficult to maintain the accuracy of this load.

2. When the polishing process is stopped, it is important to ensure that the workpiece surface is clean and carefully remove all abrasives and lubricants. Afterwards, a layer of mold rust preventive coating should be sprayed on the surface.

3. The polishing time should not be too long, as a shorter time yields better results. If the polishing process is prolonged, it may cause "orange peel" and "pitting".

4. When using diamond grinding and polishing, it is not only necessary for the workpiece surface to be clean, but also for the hands of the operator to be carefully cleaned.

5. To achieve high-quality polishing results, methods and tools that easily generate heat during polishing should be avoided. For example, polishing wheel polishing can easily cause "orange peel".

For some excellent steel materials, outstanding polishing is important. However, if the hardness of the steel surface is uneven or has characteristic differences, polishing it becomes difficult. Therefore, choosing excellent steel materials is important.
