Abstract
The paper studies machining technology, cutting parameter. It does experimentation research for drilling superfine deep-hole drilling of 2Cr13 stainless steel, of which slenderness ratio is greater than 300.The test result indicates that the drilling process is stable and reliable, the optimizing cutting technology and cutting parameters is rational, the production of the type of deep hole drilling technical problems have been solved. It has practical application in common production. The parameter can produce superfine deep holes of 2Cr13 stainless steel with the length to diameter ratio 322. In this paper, the key technologies of drilling 2Cr13 stainless steel deep hole are explained, which include selecting the system of drilling deep hole, designing of structure of deep hole bit, selecting the material of cutter blade of bit , and designing the geometry parameters of blade.
