If the method is not correct, it can form ntn bearing heat. After lubrication, it can reduce the wear of the parts; ensure the accuracy of the press; reduce the energy consumption. Lubricate the thin oil lubrication, thick oil lubrication, etc. Thin oil lubrication: the strength is the internal conflict coefficient.

Use slewing bearings; grease is very important. Use turbulent grease; not only can not get the effect it should; but it will damage the bearing.
1. The oil flow survey method takes two measuring cups; one is filled with lubricating oil; the other is placed on the table; the measuring cup filled with lubricating oil is lifted off the tabletop 30-40 cm and tilted; let the lubricating oil Gradually flow into the empty cup; investigate its activity; the quality of the lubricating oil should be slender, uniform, and continuous; if the oil flow suddenly and slowly; sometimes there is a large flow; Change.
2. The hand rubbing method rubs the lubricating oil between the thumb and the index finger repeatedly; the better lubricating hand feels lubricity, less wear debris, no conflict; if you feel the conflict between the fingers and the like ; indicates that there are many impurities in the lubricating oil; should replace the new lubricating oil.
3, the light method in the weather on a clear day; use a screwdriver to pick up the lubricant; at a 45-degree angle to the horizontal plane. Control the sunlight; investigate the oil droplets; under the light; can clearly see no wear debris in the lubricating oil is outstanding Sustainable use; if there is too much wear debris; the lubricant should be replaced.
4, oil droplet trace method to take a clean white filter paper; a few drops of oil on the filter paper; after the oil leaks; if there is a black powder on the outside; contact with the hand has a sense of resistance; Many; good lubricants are powder-free; they are dry and lubricated by hand; they are yellow.

Window Screen

Window Screen

A window screen (also known as insect screen, bug screen, fly screen, flywire, Wire Mesh, or window net) is designed to cover the opening of a window. It is usually a mesh made of metal, fiberglass, plastic wire, or other pieces of plastic and stretched in a frame of wood or metal. It serves to keep leaves, debris, bugs, birds, and other animals from entering a building or a screened structure such as a porch, without blocking fresh airflow.
