References This specification refers to the following documents. GB/T 7234-2004 Geometrical product specifications (GPS) roundness measurement terms, definitions and parameters GB/T 7235-2004 Geometrical product specifications (GPS) roundness error in radius change Of measurement GB/T 26098-2010 roundness measuring instrument For dated references, only the dated edition applies to this specification; who does not note date reference documents, The latest version (including all repair orders) are applicable to this specification.

3 Overview

Calibration is a block on the surface roughness and roundness error is very small outer cylindrical surface machining a cylindrical Standard axis is parallel to the small plane. String small plane on the cylinder radial cross-section of the high value of the F chord is scaling block High value. Scaling block for calibration and testing equipment parameters such as magnification. Typical calibration block structure shown in Figure 1. Figure 1 Schematic diagram of the calibration block

4 Metrological characteristics

4.1 Calibration block surface roughness Scaling block measuring surface roughness Ra of the surface is generally not more than 0.05μm. 4.2 Calibration blocks roundness Roundness error calibration block is generally not more than 0.10μm. Chord height value 4.3 calibration block Scaling block chord value measurement uncertainty is generally 5% to 2%. Note. The above indicators are not used to determine eligibility for reference only. ......
