Study on Drilling Method of Small Diameter Deep-hole of Titanium Alloy by Using DF of Gun Drill

摘要

By the characteristics of gun drill and the mechanisms of DF (Double Feeder) system of outside the chip, and analyzing the processing characteristics of titanium alloy and the characteristics of small diameter deep hole, the drilling device DF system of gun drill is designed, and in order to better guarantee the accuracy of parts, the monitoring system between input oil installation and gun drill fixture are designed also. The device of drill the small diameter deep hole of titanium alloy, the value of surface roughness of the parts are Ra3.2-0.4fim and the phenomenon of the ring scratches eliminated.
