The Accuracy Analysis on the External Circular of Zirconia Ceramic Spindle by Precision Machining

Abstract:

The high-speed ceramic electric spindle is applied in high-speed NC machine tools. Now the technology of ceramic spindle with its excellent performance applied to electric spindle is becoming a kind of important development trend. Each surface processing accuracy requirement of high-speed ceramic electric spindle is high. 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. This paper focuses on the research of surface roughness, roundness and cylindricity analysis of spindle external circular, which can make 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.
