**What Element Contributes to the Appearance of a Bearing Workpiece?**
When it comes to the appearance of a bearing workpiece, surface roughness plays a crucial role. It directly affects the quality, performance, and lifespan of the bearing. However, during the grinding and super-finishing processes, several factors can lead to unqualified surface roughness.
Some common causes include:
1. **Poor-quality or dull diamond dresser**: If the diamond used for dressing the grinding wheel is not sharp or of low quality, it can result in uneven surface finishes.
2. **Insufficient super-finishing time**: Not allowing enough time for the final finishing process can leave the surface rough or inconsistent.
3. **Low-quality kerosene for super-finishing**: Using poor-quality lubricants can affect the effectiveness of the process.
4. **Incorrect grinding speed and feed rate**: Too slow a grinding speed or too fast a feed rate may lead to an uneven surface.
5. **Improper oil stone quality or alignment**: A substandard oil stone or incorrect device orientation can cause surface imperfections.
6. **Excessive workpiece speed or vibration**: High workpiece speed or misalignment between the workpiece and grinding wheel axes can result in irregularities.
7. **Fast dressing speed or large gap in the dressing structure**: This can affect the uniformity of the grinding wheel surface.
8. **Incorrect grain size or hardness of the grinding wheel**: Using a wheel with too coarse or too soft grains can lead to poor surface finish.
To ensure high-quality bearings, it's essential to monitor and control these factors throughout the manufacturing process.
