Pogwiritsa ntchito makina opukutira okha, wogwiritsa ntchito amakumana ndi vuto lalikulu, lomwe ndi "kupukuta kwambiri".Nthawi yopukutira ndi yayitali kwambiri ndipo mawonekedwe a pamwamba pa nkhungu ya zida siabwino.Muzochitika zachilendo, "lalanje" lidzawonekera."Khungu", "pitting" ndi zina.Kenaka, kampani yathu idzakuuzani momwe mungathetsere vuto la "kupukuta" kwa makina opukutira okha.

Pamene mankhwala workpiece amawoneka "lalanje peel", makamaka chifukwa cha kutentha kwambiri kwa nkhungu pamwamba wosanjikiza kapena carburization kwambiri.Pamene kupopera ndi kupukuta kupanikizika kuli kwakukulu, nthawi yopera ndi kupukuta ndi yaitali, zomwe zidzachititsanso maonekedwe a zipangizo.Mkhalidwe wa "orange peel".Ndiye "peel lalanje" ndi chiyani?Ndiko kuti, pamwamba pake ndi yosakhazikika komanso yowawa.Chitsulo cholimba chachitsulo chosapanga dzimbiri chimatha kupirira kupsinjika ndi kupukuta ndi kupukuta kumakhala kwakukulu, ndipo mbale yachitsulo yosapanga dzimbiri yomwe imakhala yofewa kwambiri imakonda kugaya ndi kupukuta mopitirira muyeso.

Kotero, momwe mungachotsere "peel lalanje" ya workpiece?Choyamba tiyenera kuchotsa chilema pamwamba wosanjikiza, ndiyeno akupera mbewu kukula ndi coarser pang'ono kuposa mchenga ntchito kale, ndi kuchepetsa kutentha quenching ndi 25 ℃, ndiyeno nkhawa ikuchitika.Tsukani, kenaka gwiritsani ntchito nkhungu yokhala ndi nambala yabwino kwambiri yamchenga kupukuta, kenaka pukutani ndi mphamvu yopepuka mpaka zotsatira zake zikwaniritsidwe.

Zomwe zimatchedwa "pitting" ndi maonekedwe a maenje ngati madontho pamwamba pazitsulo zogwirira ntchito pambuyo popukuta.Izi zili choncho makamaka chifukwa zotsalira zina zosagwirizana ndi zitsulo zidzasakanizidwa muzitsulo zopangira zitsulo, zomwe nthawi zambiri zimakhala zolimba komanso zowonongeka.Ngati kupanikizika kwa kupukuta kuli kwakukulu kwambiri kapena nthawi yopukutira ndiyotalika kwambiri, zonyansazi ndi zotsalirazi zidzatulutsidwa kuchokera pamwamba pa mbale yachitsulo chosapanga dzimbiri, kupanga madontho-ngati maenje ang'onoang'ono.Makamaka pamene chiyero cha mbale ya chitsulo chosapanga dzimbiri sichikwanira ndipo zomwe zili ndi zotsalira zonyansa zolimba ndizokwera;pamwamba pa mbale ya chitsulo chosapanga dzimbiri ndi zowonongeka ndi zowonongeka kapena chikopa chakuda sichimatsukidwa, "pitting corrosion" imakhala yotheka.

Momwe mungathetsere vuto la "pitting"?Pamwamba wosanjikiza wa workpiece mankhwala ndi opukutidwa kachiwiri.Ukulu wa njere wa mchenga wa nkhungu womwe umagwiritsidwa ntchito ndi mulingo umodzi wokulirapo kuposa womwe unagwiritsidwa ntchito kale, ndipo mphamvu yopukutira iyenera kukhala yaying'ono.M'tsogolomu, gwiritsani ntchito miyala yamafuta yofewa komanso yakuthwa pamasitepe otsatirawa kupukuta, ndiyeno tsatirani njira zopukutira mutapeza zotsatira zogwira mtima.Pamene makina opukutira okha akupukuta, ngati kukula kwa grit ndi osachepera 1 mm, m'pofunika kupewa kugwiritsa ntchito zipangizo zofewa.Kuchuluka kwa kugaya ndi kupukuta kuyenera kukhala kochepa momwe mungathere, ndipo nthawiyo ikhale yaifupi momwe mungathere.
