Abstract: To drill deep holes of thin wall work pieces, many methods and technology parameters of high speed manufacturing deep holes with gun drills and GT drills on a machine center were investigated. Drilling deep holes with twist drill was solved. Technologies of conveying swarf and chip during deep hole drilling with high pressure gas and high speed drilling deep holes on thin wall work pieces were achieved.
