Mchenga woyera wa corundum, ufa wa corundum woyera, corundum wa bulauni ndi ma abrasives ena ndi abrasives wamba, makamaka ufa woyera wa corundum, womwe ndi woyamba kusankha kupukuta ndi kugaya.Ili ndi mawonekedwe a kristalo imodzi, kuuma kwakukulu, kudzinola bwino, komanso kupukuta ndi kupukuta.Ubwino monga wapamwamba wakhala akugwiritsidwa ntchito ndi kulimbikitsidwa m'mafakitale osiyanasiyana.Kotero, momwe mungasankhire pamene mukupukuta?
Kusankhidwa kwa abrasive
Abrasive ndi thupi lalikulu lomwe limagwira ntchito yodula pogaya.Ndiwo omwe ali ndi udindo wodula ntchito ndipo ndiye chinthu chofunikira kwambiri kuti gudumu lopera lipange mphamvu yopera.Abrasive ayenera kukhala bulauni corundum opangidwa ndi Xinli kuvala-resistant.Zogulitsa zake zimakhala ndi kuuma kwakukulu, kukana kutentha, kukhazikika kwa kutentha ndi kukhazikika kwa mankhwala, komanso ziyenera kukhala ndi mphamvu zinazake kuti zithe kupirira mphamvu inayake yopera.
Abrasive kusankha mfundo
Mukakupera zinthu zolimba kwambiri, gwiritsani ntchito ma abrasives a corundum mwamphamvu kwambiri.Zida zopera zomwe zimakhala ndi mphamvu zochepa zochepetsera kuti zisankhe brittle silicon carbide abrasives.
Kuwonjezera pa kulingalira za mphamvu zowonongeka za workpiece zakuthupi, kuuma kwa zinthu zogwirira ntchito ndizomwe zimasankhidwa posankha abrasives.Nthawi zambiri, kuuma kwa abrasive kuyenera kukhala nthawi 2-4 kuposa kuuma kwa zida zogwirira ntchito.Apo ayi, njere za abrasive ndi kuuma kwapansi zidzadutsa mofulumira panthawi yodula kwambiri ndikutaya luso locheka, zomwe zidzapangitsa kuti gudumu likhale lolimba kwambiri komanso limakhudza kudula.bwino, ndi khalidwe processing sizingatsimikizidwe.Choncho, kuuma kwa zinthu zogwirira ntchito kumapangitsa kuti abrasive ikhale yovuta kwambiri.
Kusankha katundu abrasive
Kuganiziridwanso kuyenera kuganiziridwanso ku zotheka kwa mankhwala mu dongosolo logaya.M'dera akupera kukhudzana, abrasives, binders, workpiece zipangizo, akupera madzi ndi mpweya sachedwa mowiriza zimachitikira mankhwala pansi chothandizira kanthu akupera kutentha ndi akupera mphamvu.Chitsulo chikagwiritsidwa ntchito, kuvala kwa abrasive kumathamanga kwambiri kuposa corundum abrasive pamene akupera zitsulo.Chifukwa chachikulu cha izi ndikuchita kwamphamvu kwamankhwala pakati pa silicon carbide abrasive ndi chitsulo.
Kuonjezera apo, kukhazikika kwa kutentha kwa abrasive kuyeneranso kuganiziridwa posankha abrasive.Pogaya zinthu zina zolimba, ngozi zina zimachitika pamene mpheroyo ili ndi chizolowezi chopanga kutentha kwambiri.
