A ball end cutter for machining a cylinder head of an automobile engine

Abstract

The utility model discloses a ball nose tool for automobile engine cylinder cover processing relates to ball nose tool technical field, a ball nose tool for automobile engine cylinder cover processing, including handle, tool shank, fixed link and ball nose tool main part, tool shank fixed connection in the top of handle, spiral channel utilizes centrifugal force to accelerate chip discharge, avoids the chip to accumulate or to wind the tool in cross -hole, reduces the chip jamming and burr generation of cutting force fluctuation, and the design of double chip flutes has increased the chip space, especially suitable for the discharge demand of multidirectional chip at cross -hole, reduces the risk of sticking knife, and the contact area of tool and chip is reduced in the clearance of tool body, reduces the generation of cutting heat, thereby reduces the possibility that aluminium alloy material sticks tool because of high temperature softening, and the chip groove further ensures that chip completely separates from tool, prevents the chip from solidifying and forming the accumulation of chip on the surface of tool, and further improves the cutting quality of ball nose tool main part.
