4 Overview

Roundness measuring instrument (hereinafter referred to as roundness meter) is a precision turning center for turning measurement base, measured by the sensor The amount of change in the actual contour to the center of rotation of the measured angular position of the measured parts to quantitative evaluation of the measured piece of a Cross section roundness measuring instruments. According to the reference axis of rotation is divided into the sensor rotary type (see Figure 1) and work Taiwan rotary (see Figure 2) two categories. Divided by the form of signal processing analog output type (recorder display, output) and the number Word output type (computer processing rating, display, output) two categories. Can be used to measure the inner and outer surface of the revolving wheel Contour roundness, concentricity and face beating and other parameters. Cylindricality measuring instrument (hereinafter referred to as the cylindricity meter) is based on the precision rotary centerline for the rotary reference, precision straight 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 A number of cross-section in different corner position of the actual contour to the radius of change of the center line of rotation to quantitative evaluation of the cylinder Cylindrical surface measuring instruments. According to the standard rotary axis formation is also divided into sensor rotary (see Figure 3) and workers Taiwan for the rotary (see Figure 4) two categories. Divided by the form of signal processing analog output (recorder display, output) and Digital output type (computer processing assessment, display, output) two categories. Can be used to measure the cylindrical surface profile of the workpiece ......
