Research On Translatable Deep Hole Drilling And Related Technology

The rotatable deep hole drill processing technology has been widely used in shipbuilding industry,especially in the processing of propeller shafts,push rods and oil holes of engine cylinders.The quality of machining tools can greatly influence the quality,efficiency and cost of hole drilling.At present,the machining tools that are used are of great dissipation,which causes high costs for companies.As a result,it is of great necessity to do research on deep hole drill processing technology.The research is mainly about deep hole drill processing technology.First,the research background,the meaning of the research,the properties of deep hole drill processing and difficulties encountered in the process of deep hole drilling will be introduced.Then UG software will be used to build 3D modeling of the rotatable deep hole drill so that aspects like geometrical shapes,materials of machining tools,cutting principles and parameters of the drill will be studied.After that the 3D modeling will be imported into the software Deform-3d to simulate the process of the cutting of the rotatable deep hole drill.And then,simulation results will be analyzed to provide a theoretical basis for the study of deep hole drill.Due to various restrictions,drilling and cutting principles of the rotatable deep hole drill will be the main point of this research.The research aims to increase the utilization ratio of the guide blocks and several kinds of blocks of different materials will be developed.In the end,the AlCrN coated guide blocks will be found to have the best performance due to its lower dissipation and longer service life.
