Study On Intractable Materials Chip-breaking By Pin Hole Vibration Drilling

In modern industrial production, the use of the material strength, hardness, toughness and other mechanical properties improved. Drilling of these difficult to process materials such as stainless steel, aluminum, high temperature alloys and titanium alloys, the chip easily broken, and because small hole drilling is a semi-closed process, only the smooth chip removal, no blocking, no plug in order to improve the durability drill degree and processing efficiency. However, if we do not block the smooth chip removal is not Serbian, the first problem to be solved is a reasonable and stable chip breaking, it can be said that the key problem is that chip processing to achieve a reasonable chip breaking. This issue is difficult to process materials for drilling small holes, through the use of vibration principles in order to achieve stability and chip-breaking technology research.Firstly, through access to lots of documents to understand the materials difficult to machine hole drilling problems, difficult to cut materials for drilling off chip technology Research on the existing cutting processing theory, the theory of chip formation and deformation analysis and research As a chip fracture of the theory. Chapter IV is on vibration drilling of the mechanism and conditions of chip breaking. Chapter V is obtained using the theory and chip breaking and chip breaking mechanism of vibration drilling conditions, combined with small hole drilling difficult materials problems, further research designed vibration drilling small holes are difficult to machine materials, broken chip devices, through the application of the device in order to achieve stability in chip-breaking requirements. Another vibration drilling holes through the test apparatus and general test hole drilling device in the drill durability, chip shape and surface roughness of the hole so the comparison to reflect the vibration drilling of several technology advantages such as geometric broken chip, increase security, improve the precision and improve the machinability of the material being processed, etc.Finally, the study of this subject difficulties and deficiencies, small hole drilling difficult materials chip-breaking technology development prospects.
