Research on Intersecting Chamfer Machining Technology for Closed Small Deep Hole Outlet End and Application
Aiming at the technical problems of machining and mirror polishing of circular arc transition surface in closed small deep holes,a new type of circular arc chamfering knife and polishing and grinding device was developed and designed.Small holes of different specifications were selected for machining tests.The test results show that the tool structure design is reasonable and the machining method is advanced.Using the newly designed tool and process,with high forming precision of the small hole inner arc transition surface,the surface roughness can reach Ra0.2 μm,and the machining efficiency is increased by 5～6 times.It provides a new process for the high-precision machining of small deep holes,and has strong guiding significance.
