4:1 Measuring tools
4:1:1 Round and flat wires
When the winding wire size is greater than 0:200mm, the measuring tool accuracy should be better than 2μm; when the winding wire size is less than or equal to 0:200mm
When measuring, the accuracy of the measuring tool should be better than 1μm: Both mechanical contact micrometers and optical non-contact diameter gauges can be used:
For micrometers, the ratio of measuring force to measuring seat diameter P should comply with the requirements of Table 1a and Table 1b: The diameter range of the measuring rod and measuring seat is shown in Table 1a:
and Table 1b: If an optical diameter gauge is used, the average of multiple readings should be taken: If other special measuring tools are required, it should be negotiated by the supplier and the buyer:
