The External Circular Precision Detection of Precision Machining Zirconia Ceramics Spindle
The electric spindle is the main form of high-speed NC machine spindle. Now the technology of ceramic spindle with its excellent performance applied to electric spindle is becoming a kind of important development trend. The performance of the electric spindle in largely determines machining precision and production efficiency of the high-speed machine tool. In order to meet the requirements of high speed, high accuracy, high reliability and small vibration in the rapid processing of machine tool, 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 external circular, 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.
