Why do polishing wheels need to be cut at a 45 degree angle
The reason why the Polishing wheel adopts a 45 degree oblique cutting is mainly due to the following reasons:

1. Prevent fiber tangential flying out: A 45 degree oblique cutting can effectively prevent fiber tangential flying out during the polishing process, which can extend the service life of the polishing buff wheel.
2. Good polishing liquid compound loading capacity: The surface of the polishing wheel after oblique cutting forms regular wrinkles, which are similar to small storage bags and can effectively load liquid wax, improving the polishing effect.
3. Perfect fit with the surface of the workpiece: The flexible deformation characteristics of the outer edge of the dividing surface enable the polishing wheel to perfectly fit with the surface of the workpiece without leaving any dead corners, ensuring even polishing.
4. Efficient cutting: Due to the fibers being cut at a 45 degree angle, the cutting efficiency is high because the fibers are not easily detached.

In summary, the polishing wheel with a 45 degree oblique cutting not only improves polishing efficiency and extends service life, but also ensures the uniformity of the polishing process and the brightness of the workpiece surface.
