Abrasion can bring a very bad damage to cutting force of the teeth pin

　　Generally speaking, if the komatsu bucket teeth pins has some abrasion damages, then the cutting force of the teeth pin would be influenced too, for example, if the abrasion damage of the komatsu bucket teeth pins is very badly, such as the serious grade abrasion damage, the teeth pin would become more and more blunt, so the cutting force of the komatsu bucket teeth pins would increased with a very fast speed and result, for example, if the abrasion damage belongs to the third grade, then the cutting force of the teeth pin would be more six times than the original teeth pin, which don’t has the abrasion damage.

　　Besides, with the happen of the abrasion damage of the komatsu bucket teeth pins, the normal force of the teeth pin can become bigger and bigger with the blunt phenomenon of the teeth pin products too, so if the komatsu bucket teeth pins has the middle grade abrasion damage, then its total normal force would increased about three times than usual.
