圆度、圆柱度是机械制造和长度测量中形状误差的重要参数。圆度测量仪是以精密回转中心为回转测量基准,通过传感器测量被测件在不同转角位置上的实际轮廓至回转中心半径的变化量,从而评定被测件在某一横截面圆度的测量仪器。圆度仪主要用于测量被测件内、外回转表面各截面轮廓的圆度、同心度和端面跳动等参数。圆柱度测量仪是以精密回转中心线为回转测量基准,精密直线运动导轨为直线测量基准,通过位于直线运动导轨上的位移传感器,测量圆柱体表面
Circularity and cylindricity are important parameters of shape errors in machine construction and length measurement. Roundness measuring instrument is a precision turning center for the gyroscope reference measurement through the sensor measuring the actual angular position of the measured position to the center of rotation radius of change in order to assess the measured cross-section of a roundness measurement instrument. The roundness meter is mainly used to measure the roundness, concentricity and end runout parameters of the profile of the cross section of the inner and outer rotating surfaces of the measured parts. Cylindricality measuring instrument is based on the precision rotary centerline for the rotary reference, precision linear motion guide for the linear measurement of reference, through the linear motion of the track on the displacement sensor, measuring the surface of the cylinder
