Kuongororwa kwerubatsiro
Simbi machubhu ine dhayeti yekunze kupfuura 22 mm uye kusvika kune 400 mm, uye kukwirira kwemadziro kwakakura kupfuura gumi mm kunofanirwa kuongororwa. Mushure mekunge ma sampuli anobhururuka
Kubheka Kuedzwa
Simbi machubhu ine dhayamu yekunze isiri yakakura kupfuura 22 mm inofanira kuongororwa kwekutora. Iyo angle yakakotama iri 90o. Iyo radius iyo 6 times The Outer Dighti yeSimbi.After ichikotama sampuli, hapana fissures kana marara anotenderwa kuti aoneke pane sampuli.
