Mold Polishing Work Environment
The polishing process should be carried out separately at two working locations, that is, the rough grinding processing location and the fine polishing processing location are separated, and care should be taken to clean the sand particles remaining on the surface of the workpiece in the previous process.
Generally, after rough polishing with oil stone to 1200# sandpaper, the workpiece needs to be polished to clean without dust, ensuring that no dust particles adhere to the surface of the mold. A polishing process with an accuracy requirement of 1 μm or more (including 1 μm) can be performed in a clean polishing chamber. For more precise polishing, it must be in an absolutely clean space, as dust, smoke, dandruff and saliva can scrap high-precision polished surfaces.
After the polishing process is completed, the surface of the workpiece should be protected from dust. When the polishing process is stopped, all abrasives and lubricants should be carefully removed to ensure that the surface of the workpiece is clean, and then a layer of mold anti-rust coating should be sprayed on the surface of the workpiece.
