BTA deep hole drilling has good processing quality and stable processing performance,which make it become the most widely used tool in the deep hole processing. there are two kinds of BTA deep hole drilling, Single tooth BTA Deep Hole Drilling and stagger tooth BTA Deep Hole Drilling. the BTA stagger tooth deep hole Drilling has higher manufacturing costs, and complicate structure, and difficult processing small hole machining, so the processing of small-diameter hole is completed by BTA single tooth deep Hole Drilling, the tagger tooth BTA deep hole drilling applications more widely, but it is essential to the Single tooth BTA deep hole drilling in machinery equipment and manufacturing industry.The Single tooth BTA deep hole drill is more abrasion deformation and vibration,these would affect the quality of deep hole drilling processing, So analyzing the single tooth BTA launched of deep hole drilling systems, to indirect direction for targeted optimization tool.In this paper, analyzing the four difficulty peck drilling.(1)The drill is Easier wear broken.(2) the cutting tool is Easier deviates from machining centers.(3) the more difficult for Chip removal;(4) the more difficult for the heat distribute during the processing.Firstly, introducing the deep hole drilling technology,introducing the structure characteristics and operating principle put The single tooth BTA as an example, Analysis the force Based on the stress analysis mathematical model of the single tooth and solving the cutting force. selecting the location distribution and the parameters of the guide strip,and analyzing the stability of cutting tool in the process of drilling.And then, analyzing the Mechanical properties analysis of single tooth BTA deep hole drilling system. establishing the Statics model and simulated and analyzed on the single tooth BTA deep hole drilling, finding the Stars wear more serious parts according to the simulation of stress and strain contours, and proving the simulation compare to the experimental results.through the Modal Analysis of a single tooth BTA deep hole drilling, Obtained its ten order natural frequencies and mode shapes deformation diagram, Learn an impact on the amplitude of frequency, avoiding the resonance and providing the basis for the process.At the same time, analyzing the harmonic response of the drill rod of single tooth BTA deep hole drilling, and obtaining the resonance frequency of the drill rod. And adjusting to the loading frequency, optimize the loading mode and reducing the vibration amplitude of the tool.Finally, select the reasonable machining parameters and cutting fluid, considerating the chip removal performance and prolonging the life of the tool. Based on the experiment and ANSYS simulation, selecting the most suitable chip cutting parameters and cutting fluid.
