The metal corrosion of the linear guide accounts for the vast majority. Especially when the weather is relatively hot, the operator's hand sweat will also cause the linear guide to rust, so Fengning Machinery advises not to directly touch the guide rail with your hands during operation. Human sweat is a colorless transparent or light yellow liquid with a salty taste, weak acidity, and a pH value of 5 to 6. In addition to sodium, potassium, calcium, and magnesium salts, it also contains a small amount of organic acids, such as urea, lactic acid, and citric acid. When human sweat comes into contact with metal, it will form a sweat film on the metal surface. The sweat film will have an electrochemical effect on the metal and corrode the metal. In order to rust the linear guide, wear gloves, finger covers, or special tools when holding the linear guide.
The current linear guide will rust, and the most important thing is that we do not understand enough about the use of linear guides. Generally speaking, when the linear guide leaves the factory, a layer of anti-rust oil will be rubbed on it, so why does it still rust? That is because many people use the guide rail and place it directly in the warehouse, without taking some other maintenance measures later. Tip everyone that after use, it is necessary to rub a layer of anti-rust oil on the linear guide. Don't think that the factory has added oil, in fact, the anti-rust oil evaporates quickly.
Store in a room temperature warehouse. Do not mix it with corrosive things, and do not put unused linear guides in the open, because the open anti-rust oil evaporates quickly, so be sure to pay attention to this. If assembled inside the equipment and covered with an aluminum alloy frame, you can regularly wipe some anti-rust oil or smooth oil to avoid smooth oil evaporation. Long working hours, the machine and the outer surface of the guide rail contact friction. The friction coefficient increases, which is not conducive to the service life of the slider.
