游标卡尺测尺的刻度是卡尺生产中最主要工艺。由于刻度的示值误差直接反映到卡尺的测量误差,因此,它又是一个精密加工工艺。以0～300毫米卡尺为例,我厂规定其刻度示值总误差为±0.016毫米。目前,一般生产卡尺的工厂都采用照相刻 Vernier caliper ruler scale is the most important caliper production process. As the scale of the indication error is directly reflected to the caliper measurement error, therefore, it is a precision machining process. Take 0 ~ 300mm caliper as an example, our factory provides the total error of the scale indication is ± 0.016mm. At present, the general production of calipers factories are using photographic moment
