Makhalidwe a mbale yokhuthala: mbaleyo ikakhuthala, khalidwe lake silili bwino kwambiri mukadula. Ngati mugwiritsa ntchito zida zoyenera zochotsera ma burrs, mutha kuchotsa mosavuta mitundu yonse ya ma burrs opangidwa ndi kudula. Nthawi yomweyo, zimakutsimikizirani chitetezo chambiri komanso mtengo wotsika wa zinthu.
Pamene makulidwe a chitsulo cha pepala afika 10mm kapena kupitirira apo, njira yodulira laser yomwe imagwiritsidwa ntchito kwambiri yafika pamlingo wogwirira ntchito. Pakadali pano, makampani opanga zinthu nthawi zambiri amagwiritsa ntchito njira zina, monga kudula plasma kapena kudula lawi. Podulira plasma, mpweya wa gasi wokhala ndi kutentha mpaka 30000 ° C umasungunula zinthuzo mu plasma kuti umalize kudula; kudula lawi ndi kudula pokweza malo oyatsira moto a chinthucho kufika pa 1150 ° C (yachitsulo chosakhala alloy) pamzere wodulira.
Kutentha kwakukulu komwe kumapangidwa ndi kudula kudzasiya zizindikiro pa workpiece ndikupanga ma burrs. Kutentha kwa zinthu kukakhala kwakukulu, burr imakhala yoonekera bwino. Burr yokhala ndi makulidwe a 3mm kapena kuposerapo si yachilendo. Zinthu zina monga makulidwe a chitsulo cha pepala, mtundu wa zinthu ndi kapangidwe kake, pamwamba ndi kutentha kwa kudula zidzapangitsanso kuti ma burrs apangidwe. Kuphatikiza apo, kukhazikitsidwa kwa magawo ogwiritsira ntchito zida ndi chinthu chomwe chimapangitsa kuti pakhale kusiyana kwakukulu pakati pa ntchito ya ogwira ntchito ndi malo abwino odulira, ma burrs ambiri adzapangidwa panthawi yodula. Pakudula kwa plasma, ngati liwiro lodula lili pang'onopang'ono kwambiri, lidzakulitsanso mapangidwe a burrs. Mwachidule, pansi pa zinthu zosiyanasiyana, pamwamba pa workpiece padzapanga ma burrs ambiri kapena ochepa. Poyerekeza ndi zigawo zazing'ono zokhala ndi ma cut kapena mabowo ambiri amkati, zigawo zazikulu zokhala ndi mawonekedwe osavuta akunja zidzapanga ma burrs ochepa panthawi yodula.
Kuchotsa mosavuta ma burrs akuluakulu
Nthawi zina, ma burrs okhala ndi mawonekedwe apadera amatha kuchotsedwa mosavuta: choyamba lolani gawo lodula la moto lizizire, kenako liyike pansi, pa pallet kapena mu chidebe. Komabe, ntchitoyi ilibe chitetezo chilichonse. Ogwira ntchito kapena ogwira ntchito oyenerera ayenera kuvala zovala zoyenera zodzitetezera kuti apewe zoopsa zomwe zingachitike chifukwa cha ntchito zomwe zili pamwambapa. Kumbali ina, kupukusa ndi kuchotsa ma burrs ndi manja kumatenga nthawi komanso kumatenga nthawi. Katundu wopitilira womwe umachitika chifukwa cha kugwedezeka kwa zida panthawi yogwira ntchito udzaika thanzi la antchito pachiwopsezo.
Pa ntchito yovutayi yokonza zinthu, makina ochotsera zinthu zotayika ndi chisankho chabwino m'malo ovuta kwambiri m'mafakitale. Makina ochotsera zinthu zotayika amatha kugwira zinthu zachitsulo zomwe sizingakonzedwe pamanja chifukwa cha ma burrs olemera kwambiri. Kafukufuku wasonyeza kuti chochotsera zinthu zotayika ndi chida chabwino kwambiri chochotsera coarse burr ya mbale yokhuthala. Chingathe kuchotsa coarse burr mosamala komanso modalirika pazigawo zodula za plasma kapena lawi. Chochotsera zinthu zotayika chimalumikizidwa mosavuta m'mphepete mwa chogwirira ntchito ndipo chimagwiritsa ntchito mphamvu yokoka kuti chichotse zinthu zotayika. Chingathenso kuchotsa bwino mamilimita angapo a ma burrs a thermal deformation pa sheet metal panthawi yodula. Kenako, m'mphepete mwapamwamba ndi pansi zimazunguliridwa popera burashi, ndipo ma burrs ena omwe amapangidwa popera amathanso kuchotsedwa.
