Contour meter, cylindricity meter, roundness meter, standard glass hemisphere

1、 Product Introduction:

SY-C11Contour meter, cylindricity meter, roundness meter, standard glass hemisphereDesigned and developed according to the JJG429-2000 standard for roundness and cylindricity measuring instruments, the standard glass hemisphere is installed into the ball seat without loosening or deforming, and is used to calibrate the axial and radial runout errors of roundness and cylindricity measuring instruments.

2、 Compliant with standards:JJG429-2000 specification for roundness and cylindricity measuring instruments

3、 Instructions for use:

Contour meter, cylindricity meter, roundness meter, standard glass hemisphereEmbedded hemispherical installation, using a roundness measuring instrument (hereinafter referred to as a roundness meter) with a precision rotation center as the rotation measurement reference, and measuring the actual contour of the measured part at different angular positions to the radius of the rotation center through sensors to quantitatively evaluate the roundness of a certain cross-section of the measured part. The standard hemispherical cylindricity measuring instrument, hereinafter referred to as the cylindricity measuring instrument, is a measuring instrument that quantitatively evaluates the surface cylindricity of a cylinder by measuring the actual contour of several sections of the cylinder surface at different angular positions to the radius of the rotation center line through displacement sensors located on the linear motion guide rail, with the precision rotation center line as the rotation measurement reference and the precision linear motion guide rail as the linear measurement reference. According to the formation method of the reference rotation axis, it can also be divided into two types: sensor rotation and worktable rotation, with different positioning depending on the method. According to the signal processing form, it can be divided into two types of parameters: analog output (recorder display, output) and digital output (computer processing evaluation, display, output).
