High precision bearing ball high quality guarantee

- Apr 30, 2019-

The quality of the high precision bearing ball will directly affect the use of the bearing. In order to produce a high-quality high-precision bearing ball, firstly, the rigidity and precision of the ball processing machine should be improved, and active vibration isolation and vibration absorption measures should be taken to absorb most of the machine tool. Vibration energy. At the same time, it improves the precision grade of the gear spindle, bearing and assembly of the machine tool spindle, guarantees the machining precision of the machine tool, and provides the basic guarantee for the vibration reduction and noise reduction of the high-precision bearing ball joint sleeve.

 

At the same time, it is necessary to scientifically formulate high-precision bearing ball processing technology, and actively adopt new industry technologies and new technologies, such as steel ball surface strengthening treatment process, heat treatment automatic wire processing, and resin grinding wheel grinding technology. In particular, the steel ball surface strengthening treatment process has a significant improvement on the vibration reduction and noise reduction of the high-precision bearing ball.

 

After the surface of the high-precision bearing ball is strengthened, a hard metamorphic layer is formed on the surface of the steel ball. The surface hardness is 2 - 3 HRC higher than the hardness of the base metal, which significantly enhances the anti-collision and anti-friction ability of the high-precision bearing ball surface. Improve the surface quality of high precision bearing balls.

 

In addition, it is necessary to strictly control the processing conditions such as abrasives and grinding discs to improve the quality of high-precision bearing balls. Abrasives generally require a clean and uniform abrasive after tanning and precipitation to ensure that most of the abrasive particles are below 0.5 μm. When superfinishing, the steel balls obtain better surface quality, surface roughness, waviness, etc. After the steel ball is combined, the vibration and noise reduction can achieve better results.
