Bearings use water-soluble cutting fluids, and users must work harder on machine maintenance and management to control the generation of corrosion and even eliminate corrosion. In order to prevent the water from corroding the metal surface, the machine tool should be fully lubricated and greased on important parts of the machine tool.
Accurately control the concentration of the cutting fluid. When the machine is shut down, flush the surface of the machine with cutting fluid and open the machine cover to dissipate the humid air in the working area of ​​the machine. To prevent the occurrence of electrical corrosion, a layer of waterproof grease should be applied to the metal surface. Moreover, the machine tool should be grounded strictly. It is not enough to ground the electrical cabinet only. To avoid the breeding and breeding of bacteria, the cutting fluid should be cleaned or replaced regularly, the chips should be removed in time, and soft water (pure water with low mineral content) should be used. Diluted the cutting concentrate.
Fag bearing steel purity
The purity of imported bearing steel refers to the degree of contamination of steel by non-metallic inclusions. Non-metallic inclusions are the kind of material of the bearing steel matrix, which destroys the continuity of the matrix and is one of the main causes of early fatigue and spalling of the bearing. Therefore, it is required that the amount of non-metallic inclusions in the bearing steel is as small as possible. In order to limit and control the presence of non-metallic inclusions in steel, they are strictly controlled in the standard.
Bearing capacity
The inner and outer rings substantially limit the bearing capacity of the bearing and must be throughout its entire circumference, and the entire width of the raceway supported on the entire surface. Solid support must be uniform and even support the bearing surface of a cylindrical or conical thrust bearing ring that the aircraft can support. This means that the bearing surface of the bearing is constructed with sufficient precision and the surface should not have any grooves, holes and other defects. In addition, the bearing surface of the bearing ring that rotates must be firmly fixed to prevent its action.
Years of bearing wear and survival
The three years of wear and tear of the bearing lost the normal office performance due to wear and tear before the total total number of revolutions or office hours at a certain speed is called the years of bearing wear and survival. In most cases, it is considered that the use of lubricating oil for use, strict sealing and dust-proof treatment can reduce the damage of the fag bearing and reduce the wear and tear. Bearing manufacturers and operators try their best to achieve success as much as possible.
In foreign countries, in the selection of water-soluble metal cutting fluids, some developed countries pay more attention to the harm of personal health, waste liquid treatment and comprehensive cost while satisfying the requirements of cutting process. Accepted by the domestic metal cutting industry.
