Brief introduction to cleaning of deep groove ball bearing parts
Kerosene cleaning agent is the traditional cleaning agent for bearing parts and finished products in general bearing manufacturers. (bearing parts washer)
The cleaning of kerosene is mainly to dilute, soften or dissolve the oily dirt on the surface of the workpiece, and then wash away all kinds of dirt after circulating filtration.
The oily dirt dissolved in kerosene is mixed with kerosene, making the kerosene for cleaning more and more viscous. More and more dirt in kerosene is easy to cause secondary pollution and make the cleaning effect unsatisfactory. The main reasons are:
1. In the grinding process of bearing parts, sodium nitrite is mostly used for rust prevention, and there is also sodium nitrite in the grinding fluid. After grinding, the surface of bearing parts will be stained with a layer of sodium nitrite crystals. Because kerosene is insoluble in sodium nitrite, the sodium nitrite crystals on the surface of parts cannot be removed.
2. Most of the final processing lubrication and cooling of bearing parts use super essential oil, and the oilstone used for super precision generally needs to be soaked. Therefore, after processing, there is still a layer of oil stain and sulfur-containing grinding powder on the surface of bearing parts.
3. The outer diameter of the bearing outer ring shall be polished after ultra precision to remove the support trace on the outer diameter surface. As the grinding fluid prepared with emulsified oil is used during grinding, a layer of viscous oil stain is formed on the surface of the ferrule after mixing water and oil, which cannot be removed by kerosene cleaning fluid.
4. Bearing parts are very dirty after grinding and over machining. If the filter system of the cleaning machine is not ideal or there is no filter system, the kerosene in the cleaning machine is easy to get dirty, so the cleaning quality is not ideal.
