• Super coarse grain hard alloy virgin raw, 100% alloy by pressing and sintering, kotero kuti kuuma ndi kulimba kwa kubowola kumawonjezeka ndi 30% nthawi imodzi.
• Mapangidwe apadera, Kubowola ndi kukumba liwiro kumakweza 20%, nthawi ya moyo imafikira 30%
• Kukhazikika kwapang'onopang'ono m'malo okhala ndi kutentha kwambiri komanso kupanikizika
• Kumaliza bwino komwe kumawapangitsa kukhala osavuta kuyeretsa
• Kukana kwambiri kuvala, kukana abrasion
• Ndiotsika mtengo chifukwa chokhala ndi moyo wautali komanso kusamalidwa bwino.
(1) pazifukwa zina, monga m'mimba mwake, jekeseni Mng'oma ndi mtunda wopopera, pamene kuthamanga kwa jet kumakhala kokwera, kudzakhala bwino kuthyola miyala;
(2) pansi pa chikhalidwe kuti nozzle awiri, jekeseni Ngodya ndi nozzle kusuntha liwiro ndi mosalekeza, mulingo woyenera kwambiri kutsitsi mtunda kumawonjezeka ndi kuwonjezeka kuthamanga, kufika 32.5 nthawi nozzle awiri pa 200MPa;
(3) kufunikira kwa liwiro la nozzle ndikuwonetsetsa nthawi yakukokoloka kwa jeti.Ikakhala yosakwana 2.9mm/s, imakhala ndi mphamvu zochepa pakukokoloka kwa thanthwe.
(4) pamene kuthamanga kuli kochepa kuposa 150MPa, kuthamanga kwa jet kumawonjezeka ndipo voliyumu yosweka thanthwe pa mphamvu ya unit imakula mofulumira;komabe, pamene kupanikizika kumawonjezeka, mphamvu yosweka thanthwe pa mphamvu ya unit imachepa pang'ono, ndipo mphamvu yothyola mwala ndiyopamwamba kwambiri pa 150MPa.
(5) Nozzle yothamanga kwambiri imasunthira kutsogolo, yokhala ndi mphamvu yabwino kwambiri yoswa miyala komanso jekeseni wabwino kwambiri wa 12.50.
