The working environment of the precision slender shaft is usually harsh, and it must also be required to withstand higher temperatures. Under such influence, the performance of the precision slender shaft will therefore be easier to change. As a part of the mechanical components, the precision slender shaft also needs regular inspection and maintenance, and it must be carried out under the state of shutdown, which has a certain effect on reducing the heat generated when the linear bearing is running.
At the same time, the number of maintenance of the precision slender shaft should be reduced as much as possible to avoid the shortening of its service life, so that the precision slender shaft can face the high temperature calmly. The anti-corrosion and anti-rust operation of the precision slender shaft should be implemented in the processing engineering. It means that when the precision slender shaft is out of the heat treatment process, it should be treated with pickling, cleaning or grinding, etc. Further improve the performance of the product itself.
In addition to the above, special attention must be paid to the storage and maintenance of precision slender shafts, as far as possible to meet the standards. The bearing ring of the precision slender shaft is also the part that is prone to rust. It is precisely because of this. Pay attention to the key protection, oiling and cleaning it; soaking it in sodium nitrite or sodium carbonate In solution; maintain and store the dryness in the environment.
When the precision slender shaft is in use, the lubricant needs to be replaced appropriately. This cannot be omitted. It is precisely because of this that there will be impurities in the lubricant after long-term use. Generally, the consequences of entering the bearing are even more serious. The outer wall of the precision slender shaft should also be cleaned in time to prevent the accumulation of dust from affecting the heat dissipation inside the device.
When it comes to the thickness requirements of the chromium-plated layer of the precision slender shaft, it should be noted that the chromium layer is coated repeatedly in the process. The plating effect is relatively good, and the secondary coating effect on the surface that has been coated is not good. At this time, it is easier to produce small defects such as delamination and peeling of the chrome-plated layer of the precision slender shaft.
The thickness of the coating of the precision slender shaft should be noted that it varies according to the use situation. When the mechanical load is light and general protection, the thickness should be 10-20μm; when the sliding load and the pressure are not too high, the thickness is 20-25μm; when the mechanical stress is large and the corrosion resistance is strong, the thickness should be as high as 150 ~300μm; Hard chromium plating is generally sufficient for the thickness of the precision slender shaft.
