Hiwin linear guides are easily corroded during use due to external environmental factors. The corrosion of linear guides is mainly caused by two reasons: one is the metal erosion of the bearings themselves, and the other is the erosion of tool elements.
The metal erosion of linear guides accounts for the vast majority, and due to the special working environment, rust is often unavoidable. Especially when the weather is hot, the operator's hand sweat can also cause corrosion of the linear guide rail. This is because when human sweat comes into contact with the bearing, a sweat film will form on its surface, and the salt in the sweat on the metal surface will react with the metal and cause erosion. It is understood that during the humid and rainy season every year, the frequency of rusting on linear guides is particularly high, especially in coastal areas. The main reason is that the anti-wear agents such as sulfur and phosphorus in the guide rail oil are hydrolyzed by the main component of cutting fluid, water. Sulfur, phosphorus and other components have serious corrosiveness to steel parts, which also leads to the rusting of Hiwin linear guides.
