Chopingasa Choyesera Cholondola

Mbali yofunika kwambiri ya ma gauge blocks ndi yakuti amatha kuphatikizidwa pamodzi popanda kusatsimikizika kwenikweni. Ma blocks amalumikizidwa ndi njira yotsetsereka yotchedwa wringing, yomwe imapangitsa kuti malo awo athyathyathya kwambiri azigwirana pamodzi. Ma gauge blocks ochepa angagwiritsidwe ntchito kupanga kutalika kolondola mkati mwa mtunda wosiyanasiyana. Pogwiritsa ntchito ma blocks atatu nthawi imodzi otengedwa kuchokera ku seti ya ma blocks 30, munthu akhoza kupanga kutalika kulikonse mwa 1000 kuyambira 3.000 mpaka 3.999 mm mu masitepe a 0.001 mm (kapena mainchesi 0.3000 mpaka 0.3999 mu masitepe a 0.0001 inchi). Ma gauge blocks adapangidwa mu 1896 ndi katswiri wa makina waku Sweden Carl Edvard Johansson. Amagwiritsidwa ntchito ngati chizindikiro cha kuwerengera zida zoyezera zomwe zimagwiritsidwa ntchito m'masitolo ogulitsa makina, monga ma micrometer, sine bars, calipers, ndi dial indicators (akagwiritsidwa ntchito poyang'anira). Ma gauge blocks ndi njira yayikulu yoyezera kutalika komwe imagwiritsidwa ntchito ndi makampani.
