Opanga nyundo amakutengerani kuti mumvetsetse kufunikira kwa nyundo zopuntha

Wopanga nyundo amakuuzani kuti pali mitundu yambiri ya nyundo zomwe zikugwiritsidwa ntchito panopa, koma zomwe zimagwiritsidwa ntchito kwambiri ndi nyundo yooneka ngati mbale, chifukwa ili ndi mawonekedwe osavuta, ndi yosavuta kupanga, komanso imakhala ndi mphamvu zambiri. Lili ndi mapini awiri, imodzi yomwe imakhomeredwa pamtengo wa pini, ndipo ngodya zinayi zingagwiritsidwe ntchito pozungulira kugwira ntchito. Kuwotcherera, kuyika kuwotcherera tungsten carbide kapena kuwotcherera kwapadera kosagwirizana ndi aloyi kumbali yogwira ntchito kuti atalikitse moyo wautumiki, koma mtengo wopangira ndiwokwera kwambiri. Kusamva bwino kwa abrasion. Nyundo ya annular ili ndi dzenje limodzi la pini, ndipo ngodya yogwira ntchito imasinthidwa panthawi ya ntchito, kotero kuvala kumakhala kofanana ndi moyo wautumiki ndi wautali, koma kapangidwe kake ndi kovuta. Wopanga nyundo amakuuzani kuti nyundo yachitsulo yamakona anayi ndi mbale yachitsulo yokhala ndi kulimba kwambiri pazigawo ziwirizi komanso kulimba kwabwino mu cholumikizira choperekedwa ndi mphero. Ndizosavuta kupanga komanso zotsika mtengo.
