Such as，normol methods have some prolem，the error f the pore diameter，drill life and burrs are presented.As a result，the advanced technological effect of varying-parameters-vibration drilling is proved. The study of changed deep drilling holes take the advanced govenments.It is a new technology and method .Before drilling,it have a small feed,so that ,there have a lot of time to increce the acuracy.Present investigation shows that the new method for vibration drilling,in which vibration parameters are changed with the optimal parameters of the stages,is an effective way to decrease error of drilling deep holes. Basing on the tudy of changed deep drilling holes,wo can study more things about the drilling deep holes.
