The Inner Hole Precision Detection of Precision Machining Zirconia Ceramics Spindle
The high-precision component named full ceramic high-speed electric spindle is used in high speed NC machine tools. Electric spindle have very high demand for the stability and dynamic balance of ceramic spindle when high-speed rotation. In order to ensure the smooth operation of high-speed spindle and realize the dynamic balance of the spindle, it is necessary to make a rigorous precision testing for the precision-processed spindle and obtain reliable data to meet the design standards and performance requirements of all ceramic high-speed spindle. In this paper, contact Surtronic25 type roughness measuring instrument is used for surface roughness analysis, and Leitz ultra PMM-C12.10.7 type tri-ordinate measuring machine is used for the roundness and cylindricity testing analysis of spindle hole, which can make the surface roughness, roundness, and cylindricity of the precision-processed zirconia ceramic spindle pore to meet the design requirements and provide reliability safeguard to promote the using life and high-speed dynamic balance stability of the whole electric spindle.
