| Abstract: | Conventional measuring methods for evaluating error motion of spindle rotation are inadequate to meet the current needs of ultra precision spindle bearing systems.In this paper, therefore, a new measuring method for spindle rotational accuracy based on a three points method was proposed. This method made it possible to reduce considerably the time and effort required in measuring the spindle rotational accuracy. Measurement of error motion to the nano-meter order was attained. Furthermore, this method was proved to be an effective method for measuring the out-of-roundness of a testpiece. |
