  In the nineteen ninety five year, one of the professional komatsu bucket teeth pins production manufactures had make a test about the cutting force of the teeth pin, the testing result is that if the komatsu bucket teeth pins has a very serious abrasion damage, then the whole teeth pin can be easy to break off, the main reason is because the normal force of the komatsu bucket teeth pins has been increased at the same time too.

  So from the macro level, if the komatsu bucket teeth pins has the middle grade abrasion damage, during the cutting period, the machine would be easy to shakes, and the total digging resistance force has increased very obvious; and if the abrasion damage level change into the serious level, during he cutting period, the machine would produced out some strange shakes, and the working device part would also has the serious point head phenomenon, so writer suggests people never use the bigger machine in some bad working conditions.
