The smoothness of the machine tool includes the smoothness of bearings, gears, guide rails and tops. The smooth grease of the machine tool includes: hydraulic oil, hydraulic guide oil and smooth oil (fat); different types of machine tools and different working conditions have different functions for smooth oil. Different needs:
1, the bearing is smooth:
1) Smoothness of sliding bearing: Sliding bearing is a commonly used transmission method; smooth oil does not only have a smooth effect but also has a cooling effect; therefore, it requires a smooth, low-viscosity smooth oil with excellent smoothness; Anti-oxidation, anti-wear, anti-rust and anti-foaming properties. Fine sliding bearings for grinding stone spindles of fine grinding machines; 1 micron for bearing clearance; high viscosity (above 30000r/min) should be used Very. Drumsticks Johor rose to a smooth oil of 2. 0mm2 (40 ° C).
2), the smoothness of the rolling bearing: the rolling bearing on the machine; because of the friction coefficient.

The demand is that the rolling bearing is special except for large and rough; it is usually not possible to use grease containing solid smoothing agent.
2, the smoothness of the gear:
The impact and oscillation of the gear of the machine tool is not large; the load is better than that of the 悴恍枰褂 悴恍枰褂 砑蛹 砑蛹 砑蛹 蠡 蠡 蠡. The demand is concerned with how to avoid the thermal deformation of the headstock; Gears; gear oils containing anti-wear agents should be used; gear oils with smooth circulation or smooth oil bath; in addition to anti-oxidation; anti-corrosion, anti-wear, anti-corrosion and anti-foaming properties. Variety selection of suitable gear oil and suitable viscosity.
3, the smoothness of the guide rail:
The load and speed of the guide rail change a lot; usually the load on the guide rail is 3-8N/cm2, but because the guide rail frequently repeats the movement; therefore, the gap is simple and smooth; even the semi-dry smoothness causes the appearance of the flaw; except for the machine description and data Smoothness is the main reason for inducing defects. In order to overcome the appearance of sputum; in addition to the use of fluorine resin rail veneer; in the improvement of smoothness; mainly with smoothing oil containing anti-climbing agent; the guide rail is smooth, usually choose viscosity 32, 68, 100, 150 rail oil; Spanish Eagle rail oil BESLUXLUDER series (32; 46, 68; 100, 150, 220) in line with ISO6743/4 specifications; L-HG grade.
4. The top of the machine tool is a special type of bearing:
The fixed top load is not large; today, high-speed machine tools use reversed tip; the complex load is larger; therefore, they are all sealed with smooth grease to smooth.

The equipment skill of small and medium-sized bearing cylindrical bore bearing will be damaged. The best way to identify the false bearing is the classification of the preload of the imported bearing and the reason why the bearing oscillates and its damping method
