【Abstract】 Generally a hole with L/D≥4 is defined as deep hole. Five different deep hole working systems and their application are introduced. The vibration cutting technology isused in these systems, So that these systems can be called"the technology of deep hole working with vibrating cutting". By this technology the problem of break and removal during deep hole drilling is rellably solved and in practice the diameter of DF drill bit can be as small as φ6.更多还原
