Barrel Drill Use Instance

Barrel drill instance (the automobile parts oblique hole machining)

Workpiece material:SCM4（HS35）	Parts diagram
Processing machinery: barrel drill special machine
Tools:φ6x350x19.05（G2F）
Conditions: Rotation speed 4200r/min Cutting speed 80m/min Feed rate 0.05mm/r Cutting depth 50~100mm

Results: HSS twist drill for drilling process in use after the barrel drill, improve the accuracy of the barrel drill, extend the life of the barrel drill to achieve the effect of cost-cutting.

Summary: deep hole barrel drill is first used in weapons manufacturing industry, hence the name barrel drill. In order to effectively use the barrel drill, must maintain a certain relationship between the hydraulic and oil amount. Barrel drill work process if the oil pressure is too low, the chip will be stuck in the barrel drill pipe, barrel drill damage the barrel drill must pay attention to this point.
