Want to give a mirror effect to cemented carbide die? Want to have a clean mirror? It seems to be a little difficult, because the hardness of the cemented carbide itself is high, the conventional processing is grinding. The diamond wheel is used. If you want to polish it, you use a finer wheel. Common ones like watches are so dry. .
The polishing process of cemented carbide die is divided into two work points to complete, that is, the rough grinding processing location is separated from the fine polishing processing location, and care must be taken to clean the remaining sand particles in the previous process. Generally, after rough polishing is completed with oilstone to sandpaper, the workpiece should be transferred to a dust-free room for polishing to ensure that no dust particles in the air stick to the surface of the mold. If high-quality polishing is performed, it must be in a very clean space, because dust, smoke, dandruff and saliva may scrap a very good polished surface. After the polishing process is completed, the surface of the workpiece must be protected from dust.
To achieve a good polishing effect, the workpiece should be marked with the polished surface roughness at the beginning of the machining. When a workpiece is determined to be mirror polished, it is necessary to select steel with better polishing performance and heat treatment. Achieve the desired effect.
