. In order to improve quality of deep hole finishing, a new method of deep hole honing based on squeeze film technology is put forward. According to fluid lubricates theory, Renault equation of deep hole honing squeeze film damper (SFD) is established, squeeze film force is solved by immense short bearing theory and the effect of the eccentricity of SFD on the damping coefficient is analyzed by MATLAB. Spindle of deep hole honing with SFD is designed based on theory research, and experimental research is carried on. Experimental result shows that SFD with reasonable design parameters has excellent damping function to honing spindle, and it can make vibration of honing spindle reduced 20%～30% and quality of deep hole machining improved 10%～20%.
