Zomwe ziyenera kutsatiridwa panthawi yozimitsa shaft ndi dzenje?

Pamene kutsinde workpiece ndi mabowo kuzimitsidwa, ananyengerera panopa kugawa padziko dzenje ndi wosagwirizana, zomwe zimayambitsa kutentha osagwirizana, nthawi zambiri kutenthedwa kapena Kutentha kwambiri, ndipo m’mphepete mwa dzenje mwina kuyambitsa ming’alu pa quenching ndi kuzirala. Bowolo likhoza kukulungidwa ndi mkuwa kapena kulumikiza ndi zikhomo zamkuwa, kotero kuti mphamvu yowonongeka igawidwe mofanana mozungulira dzenjelo ndipo ingalepheretse kusweka.
