s4, some chips are generated in cutting, the chips fall into the containing groove (8), the bottom of the containing groove (8) inclines, the falling chips roll back into the containing box (10), the containing box (10) full of the chips is taken out by sliding the containing box (10) on the guide plate (9), and normal use of the machine is prevented from being influenced by the chips.
