  • 光学式仮想Vブロック方式を用いたスピンドル回転誤差測定システム


Run-out measuring instruments with capacitance displacement probe are widely used in industry. However,this measurement method has the defect that measurement result depends on a feature of measured object. Furthermore,in measurement at one section the attachment errors such as eccentric and tilt of measured object are never detected. We compare the optical 3-point measurement by virtual V-block method which does not depend on a feature of a measured object to the 2-point measurement with capacitance displacement probe in view of measurement principle. And we show how to separate the attachment error from the run-out error of spindle.
