Hyper-fine grinding products and polishing tools can offer better lapping effect on the paint surface, which makes the surface of products have good flatness, smooth finish and comfortable grip.
By using manual methods, hyper-spreading spots can be produced while the surface temperature is higher than T1, this is termed induction of a hyper-spreading spot.
用人为的方法，在表面温度高于T1时产生超前扩展点的做法叫做超前扩展点的诱导。
