Study on the Life of Drilling High Speed Steel Bits
High speed steel cutting performance is poor,using the traditional processing method to drill high speed steel parts,easy to appear the tool life is short,easy to damage and other problems.In this paper,the tool structure,coating selection,machining cooling mode and machining program are optimized.After many cutting tests,the tool life of the optimized bit is obviously increased,and the axial drilling force of the bit is reduced by about 50%.
