In the polishing process, choosing the right particle size and hardness of the stone is one of the key factors to ensure the polishing effect of the mold. So, how should we choose the right stone particle size?
First of all, we need to understand the purpose of polishing. Different polishing purposes require different stone sizes. For example, in order to remove burrs and larger bumps and depressions, we need to use a coarser grit size;For fine polishing, you need to use a finer grit size to get a smoother surface.
Secondly, we need to understand the material and requirements of the mold surface. Different surface materials require different grit sizes. For example, metal surfaces such as copper molds and aluminum alloys need to be polished with finer stones, while stainless steel, alloy molds, etc., can be polished with coarser stones.
Finally, we also need to consider the experience of the operator and the performance of the polishing tool. The performance of the polishing tool has an important influence on the choice of grain size of the stone. For example, some polishing tools can refine the grain size of the stone to a very fine degree, while others can't. Therefore, when choosing the grit size, we should combine the experience of the operator and the performance of the polishing tool to achieve better polishing results.
In conclusion, choosing the right grit size is a very important step in the polishing process. We need to choose the appropriate stone particle size according to the polishing purpose, surface material, operator's experience and the performance of the polishing tool to ensure that better polishing results can be achieved.
