Today I learned something new. A customer gave me a picture of a bearing, as shown in the figure below. Inside the black bearing, the balls are one next to each other. Without the retainer, it is ok, but there is actually a cylindrical "foreign body" hidden inside! It's strange, what kind of bearing ... Read More

1. Optimization of Grinding Process Parameters and Force Fluctuation Control: By adjusting the process parameters of continuous grinding (such as feed rate and cutting depth), reduce the tooth surface ripples caused by periodic cutting force fluctuations, especially in gears with fewer teeth. The ... Read More

The reasons for choosing honing (honing) over grinding (grinding) are as follows: Reduce noise characteristics The microstructure of the tooth surface generated by hobbing is more conducive to reducing the noise of gear transmission. Avoid the risk of heat damage The hobbing process eliminates the ... Read More
