Kusankhidwa kwa binder ndi abrasive kumagwirizana kwambiri.Mwachitsanzo, kugwiritsa ntchito CBN nthawi zambiri kumafuna kuti gudumu logaya likhale losasinthika pakagwiritsidwe ntchito ndipo lisachotsedwe pa chida cha makina mpaka litatheratu.Popeza matenthedwe matenthedwe a CBN ndiabwino kwambiri, ndizothandiza kwambiri kugwiritsa ntchito chomangira chachitsulo.Kuphatikiza kwa awiriwa kumapereka mikhalidwe ya kudula kozizira.Chifukwa kutentha kutentha kumafalikira kudzera mu abrasive ndikugayagudumu, ndiyeno kunyamulidwa ndi ozizira, ndi mofulumira kwambiri kuposa kulowa workpiece.
Pali mitundu iwiri yomangira zitsulo: electroplating ndi sintering.Electroplated akuperamawilo samakonzedwa, amapangidwa kukhala mawonekedwe olondola pachiyambi ndikugwiritsidwa ntchito mpaka atatopa.Mawilo opukutira zitsulo a Sintered nthawi zambiri amakonzedwa ndi spark yamagetsi, ndiyeno amayikidwa pazida zamakina ngati mawilo opukutira a electroplated.Kuthamanga kwa ma gudumu a sintered ndi electroplated akupera pa spindle ayenera kukhala osachepera 0.0125mm.Kwa mawilo omangirira zitsulo, ndikofunikira kwambiri kuchepetsa kuthamanga kwa spindle.
Chifukwa mtunda umene njere za abrasive zimachokera ku mgwirizanowu ndi wochepa kwambiri, ngati kuthamanga kufika ku 0.025mm, mapeto amodzi akugayagudumu lidzakhala lodzaza, zomwe zimapangitsa kuti ziwonongeke kwambiri, ndipo mapeto ena adzakhala opepuka komanso akuthwa.Mawilo ena opangidwa ndi electroplated amatha kutulutsa utali wocheperako wocheperako (pafupifupi 0.125mm).Komabe, ma arc radius ya mawilo opukutira a electroplated ndi akulu kuposa 0.5mm.Nthawi zambiri, mawilo opukutira a electroplated amagwiritsidwa ntchito popera kwambiri, pomwe mawilo achitsulo a sintered ndi oyenera kugaya zida za ceramic.
Monolithic zitsulo zomangidwagudumu loperaali ndi kachulukidwe kakang'ono ka kusinthasintha kwa kugwedezeka, kuthamanga, kuthamanga kwazizindikiro ndi zina zogwirira ntchito.Ngati kulimba kwa chopukusira, workpiece ndi fixture ndi osauka, kapena kubala kwa makina chakale chida si bwino, ndipo palibe kugwirizanitsa chipangizo pa chida makina, ntchito electroplated gudumu akupera pansi chikhalidwe ichi adzatsogolera mavuto pa moyo wautumiki wa gudumu lopera, kumaliza kwa workpiece ndi mawonekedwe apamwamba.Malinga ndi kugwedezeka ndi kukhazikika kwa chida cha makina ndi zinthu zina zenizeni, nthawi zina ndibwino kugwiritsa ntchito mawilo opukutira opangidwa ndi utomoni.
Chomangira cha resin chimakhala ndi mphamvu yochepetsera mphamvu yakugwedezeka.Zachidziwikire, zida ndi nthawi zomwe zikuphatikizidwa pakukonza ndi kuvala mawilo omangirira utomoni zidzakulitsa mtengo.Ceramic bond imagwiritsidwa ntchito kwambiri.Chifukwa gudumu lomangira lomangika lili ndi mabowo, madzi odulira amatha kulowa bwino mu arc yopera, ndipo pali mabowo akulu kuti asunge zinyalala zovala.Nthawi yomweyo, gudumu lomangira la ceramic limatha kukonzedwa mosavuta kuti likhale loyenera ndikukulitsidwa pogwiritsa ntchito zida za diamondi.
