The scraper Fineness Meter can be verified at the Institute of Metrology (Institute). There are several scraper fineness gauges in the company-level quality inspection center, production control inspection, and printing factory, which need to be replaced regularly due to frequent use. Pass on other scraper gauges. The scraper Fineness Meter is composed of scraper and scraper.
Scraper precision:
(1) The flatness of the plane on the scraper is 0.003 mm.
(2) The flatness of the bottom plane of the chute is 0.003 mm.
The squeegee is verified by an optical comparator, but the user of the scrambler does not have an optical comparator, and generally it is only a factory inspection. A finite number of points are taken to test the flatness of the plane on the random plate. Take the plane of a certain micron scale line as 0 μm, measure the groove depth at this point; take the plane of another micron scale line as 0 μm, measure the groove depth at another point, and so on. There are two points to note:
