Abrasive lamba kupera ndi njira yofewa yopera, yomwe ndi teknoloji yopangira pawiri yokhala ndi ntchito zambiri zopera ndi kupukuta.
Mbewu za abrasive pa lamba wa abrasive zimakhala ndi mphamvu yodula kwambiri kuposa njere za abrasive za gudumu lopera, kotero kuti kugaya kwake kumakhala kokwera kwambiri, komwe kumawonekera pakuchotsa kwake, kugaya chiŵerengero (chiŵerengero cha kulemera kwa workpiece yochotsedwa ku chiŵerengero). kulemera kwa abrasive kuvala) ndi mphamvu ya makina Mlingo wogwiritsiridwa ntchito ndi wapamwamba muzinthu zonse zitatu.
Abrasive lamba akupera kumapangitsa pamwamba pa workpiece apamwamba mu khalidwe.Chifukwa ali ndi ntchito zingapo akupera ndi kupukuta, ndipo poyerekeza ndi kugaya gudumu akupera, lamba akupera amatchedwa "ozizira akupera", ndiko kuti, kutentha akupera ndi otsika, ndi pamwamba workpiece si zophweka kuwotcha.
Mawonekedwe apamwamba a workpiece amawonekera pamtengo waung'ono wa roughness, mkhalidwe wabwino wotsalira wotsalira, ndipo palibe ming'alu ya microscopic kapena kusintha kwa metallographic pamwamba.Kupanikizika kotsalira pamwamba pa abrasive lamba akupera workpiece makamaka mu mkhalidwe compressive kupsyinjika, ndipo mtengo wake nthawi zambiri -60~-5Kg/mm², pamene akupera gudumu akupera ndi makamaka kukanika kupanikizika, kotero abrasive lamba akupera kwambiri. zothandiza kulimbitsa pamwamba pa workpiece, kusintha kutopa mphamvu workpiece.
Makina opangira lamba abrasive ali ndi kugwedezeka kochepa komanso kukhazikika kwabwino.Chifukwa cha kulemera kwake kwa lamba wa abrasive, kusanja kwa dongosolo logaya ndondomeko kumakhala kosavuta kulamulira.Ziwalo zonse zozungulira (monga mawilo olumikizana, magudumu oyendetsa, magudumu othamanga, ndi zina zotero) zimavala zochepa kwambiri, ndipo sipadzakhala kusalinganika kwamphamvu monga gudumu lopera.chinthu.Kuphatikiza apo, zotanuka akupera mphamvu ya lamba abrasive akhoza kwambiri kuchepetsa kapena kuyamwa kugwedezeka ndi zotsatira kwaiye pa akupera.Liwiro lopera ndilokhazikika, ndipo gudumu loyendetsa lamba silidzakhala ngati gudumu lopera.Zing'onozing'ono m'mimba mwake, pang'onopang'ono liwiro lidzakhala.
Lamba wa abrasive ali ndi kulondola kwakukulu kopera.Chifukwa cha kusintha kwa khalidwe lamba la abrasive komanso kupanga mapangidwe a abrasive lamba, kugaya lamba wa abrasive walowa kale m'gulu la makina olondola komanso olondola kwambiri, olondola kwambiri omwe amafika pansi pa 0.1mm.
Mtengo wotsika wa kugaya lamba wa abrasive:
Zida ndi zosavuta.Poyerekeza ndi chopukusira gudumu, chopukusira lamba ndi chosavuta.Izi makamaka chifukwa lamba ndi wopepuka kulemera, mphamvu yopera ndi yaying'ono, kugwedezeka pa nthawi yopera ndi kochepa, ndipo zofunikira zolimba ndi mphamvu za chida cha makina ndizochepa kwambiri kuposa chopukusira gudumu.
Opaleshoniyo ndi yosavuta ndipo nthawi yothandizira ndi yochepa.Kaya ndi pamanja kapena lamba akupera lamba, ntchito yake ndi yosavuta.Kuchokera pakusintha ndikusintha lamba wa abrasive mpaka kumangirira chogwirira ntchito kuti chisinthidwe, zonsezi zitha kutha kwakanthawi kochepa.
Chiŵerengero chogaya ndi chachikulu, mphamvu yogwiritsira ntchito mphamvu ya chida cha makina ndipamwamba, ndipo kudula bwino ndikokwera.Izi zimachepetsa mtengo wa zida ndi mphamvu zodulira zida zolemera kapena voliyumu yofanana, ndipo zimatenga nthawi yochepa.
Abrasive lamba akupera ndi otetezeka kwambiri, ndi phokoso lochepa ndi fumbi, zosavuta kulamulira, ndi ubwino chilengedwe.
Chifukwa lamba wa mchengawo ndi wopepuka kwambiri, palibe ngozi yovulaza ngakhale itasweka.Abrasive lamba akupera si aakulu monga mchenga kunja gudumu akupera, makamaka pa youma akupera, akupera zinyalala makamaka zinthu workpiece kuti kukonzedwa, ndipo n'zosavuta kuchira ndi kulamulira fumbi.Chifukwa cha gudumu kukhudzana mphira, abrasive lamba akupera sangapange chikoka okhwima pa workpiece ngati gudumu akupera, kotero phokoso processing ndi laling'ono kwambiri, kawirikawiri.<70dB.Zitha kuwoneka kuti kuchokera kuchitetezo cha chilengedwe, kugaya lamba ndikoyeneranso kukwezedwa.
Abrasive lamba akupera ndi kusintha ndi chosinthika:
Abrasive lamba akupera angagwiritsidwe bwino ntchito pogaya malo lathyathyathya, mabwalo mkati ndi kunja ndi zovuta yokhotakhota pamalo.Kupanga abrasive lamba akupera chipangizo mutu monga gawo ntchito akhoza kuikidwa pa lathe pambuyo kutembenuka akupera, komanso akhoza kuikidwa pa planer ntchito, komanso akhoza kupangidwa ngati zosiyanasiyana makina apadera akupera.Kugwiritsa ntchito gawo ili lakupera lamba kumatha kuthetsa zida zina zovuta ku makina, monga kuwongolera bwino kwamitengo yayitali kwambiri komanso yayikulu kwambiri ndi zida zandege.
Wapamwamba akupera ntchito ndi kusinthasintha ndondomeko makhalidwe lamba abrasive kudziwa kuti ali ndi osiyanasiyana kwambiri osiyanasiyana ntchito, kuchokera tsiku ndi tsiku kupanga mafakitale m'magulu onse a moyo, abrasive lamba akupera pafupifupi chimakwirira minda yonse.Mitundu yosiyanasiyana ya mafomu ofunsira komanso kusiyanasiyana sikufanana ndi njira ina iliyonse yopangira.Makamaka, imatha kupukusa pafupifupi zida zonse zauinjiniya.Kuwonjezera pa zipangizo zomwe zingathe kukonzedwa ndi mawilo opera, malamba otsekemera amathanso kupanga zitsulo zopanda chitsulo monga mkuwa ndi aluminiyamu, ndi zinthu zofewa zopanda zitsulo monga matabwa, zikopa, ndi pulasitiki.Makamaka, "ozizira" akupera mphamvu ya kupera lamba imapangitsa kuti ikhale yapadera kwambiri pokonza zinthu zosagwira kutentha komanso zovuta kupukuta.
