Choyamba, kumalizidwa kwapamwamba ndi kukhwinyata kwa pamwamba ndi lingaliro lomwelo, ndipo kumaliza pamwamba ndi dzina lina la kukhwinyata pamwamba. Mapeto a pamwamba amaperekedwa molingana ndi momwe anthu amawonera, pomwe kuuma kwapamtunda kumaperekedwa molingana ndi mawonekedwe enieni apamtunda. Chifukwa cholumikizana ndi muyezo wapadziko lonse lapansi (ISO), China idatengera kuuma kwapamtunda ndikuthetsa kutha kwa ma 1980s. Pambuyo pa kulengeza kwa miyezo ya dziko lonse ya roughness GB3505-83 ndi GB1031-83, kutsirizitsa pamwamba sikugwiritsidwanso ntchito.
Pali tebulo lofananiza lofananira ndi kumalizidwa kwapamwamba komanso kuuma kwapamwamba. Ukali uli ndi kawerengetsedwe ka muyeso, pomwe kusalala kumatha kufananizidwa ndi geji yachitsanzo. Chifukwa chake, roughness ndi yasayansi komanso yolimba kuposa yosalala.
Kunyezimira kwa pamwamba kumasonyeza kuchulukira kwa kunyezimira kwa kuwala pamwamba pa chinthu. Kwa diso lamaliseche, ngati pamwamba diffuse kusinkhasinkha ndi wamphamvu, izo ziri pafupi ndi galasi zotsatira, ndi glossiness ndi mkulu. M'malo mwake, ngati mawonekedwe owoneka bwino akunja ndi ofooka, glossiness ndi yotsika, kotero glossiness imatchedwanso galasi glossiness. Zomwe zimakhudza gloss pamwamba zimagwirizana ndi momwe thupi limakhalira pamwamba ndi mankhwala omwe amagwiritsidwa ntchito pamtunda. Njira yodziwira gloss ya galasi pamwamba pa chinthu imafuna kugwiritsa ntchito mita ya pamwamba.
Kuvuta kwa pamwamba kumatanthawuza kusalingana kwa katalikirana kakang'ono ndi nsonga ting'onoting'ono ndi zigwa zomwe zili pamalo okonzedwa. Mtunda (mtunda wa mafunde) pakati pa nsonga ziwiri kapena zigwa ziwiri ndizochepa kwambiri (zosakwana 1mm), zomwe ndi zolakwika zazing'ono za mawonekedwe a geometric. Zing'onozing'ono za roughness pamwamba, ndi zosalala pamwamba.
Kuuma kwapamwamba kumapangidwa ndi njira yopangira zinthu zomwe zimagwiritsidwa ntchito ndi zinthu zina, monga kukangana pakati pa chida ndi pamwamba pa gawo panthawi yokonza, mapindikidwe apulasitiki azitsulo zachitsulo panthawi yolekanitsa chip, ndi kugwedezeka kwapamwamba kwambiri pakupanga. dongosolo. Chifukwa cha kusiyana kwa njira zogwirira ntchito ndi zipangizo zogwirira ntchito, kuya, kachulukidwe, mawonekedwe ndi mawonekedwe a zizindikiro zomwe zatsala pamtunda wokonzedwa ndizosiyana.
Ukali wapamtunda umagwirizana kwambiri ndi mawonekedwe ofananira, kukana kuvala, mphamvu ya kutopa, kuuma kwa kukhudzana, kugwedezeka ndi phokoso la magawo amakina, ndipo zimakhudza kwambiri moyo wautumiki komanso kudalirika kwazinthu zamakina. Ra kawirikawiri amagwiritsidwa ntchito polemba chizindikiro.
Chikoka cha roughness pamwamba pa zigawo makamaka kuonekera m'mbali zotsatirazi: Pamwamba pamwamba, ang'onoang'ono okhudzana ndi malo ogwirizana pakati pa malo ofananira, kupanikizika kwakukulu, kusagwirizana kwakukulu, komanso kuvala mofulumira.
Zida za Xinfa CNC zili ndi mawonekedwe abwino komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:CNC Tools Opanga - China CNC Tools Factory & Suppliers (xinfatools.com)
Chikoka pa kukhazikika kwa kuyenera Kwa chilolezo chovomerezeka, chowotcha pamwamba, chimakhala chosavuta kuvala, kuchititsa kusiyana pang'onopang'ono kuwonjezeka panthawi yogwira ntchito; pofuna kusokoneza, popeza nsonga za microscopic convex zimafinyidwa lathyathyathya panthawi ya msonkhano, kusokoneza kwenikweni kumachepetsedwa, ndipo mphamvu yolumikizira imachepetsedwa.
Kumakhudza mphamvu ya kutopa Ziwalo zolimba zimakhala ndi mbiya zazikulu pamalo awo, zomwe zimakhudzidwa ndi kupsinjika ngati notche zakuthwa ndi ming'alu, motero zimakhudza mphamvu ya kutopa kwa ziwalozo.
Kumakhudza kukana kwa dzimbiri Magawo okhwima amapangitsa kuti mpweya woyaka kapena zakumwa zamadzimadzi zilowe mosavuta mkati mwa chitsulo kudzera m'zigwa zapamtunda, zomwe zimapangitsa kuti pakhale dzimbiri.
Kumakhudza kusindikiza Malo osalongosoka sangagwirizane bwino, ndipo mpweya kapena zakumwa zimatuluka kudzera pamipata pakati pa malo olumikizana.
Kukhudza kuuma kwa kukhudzana ndi mphamvu ya mgwirizano pamwamba pa gawo kuti ikanize kukhudzana ndi mapindikidwe pansi pa mphamvu zakunja. Kuuma kwa makina kumadalira kwambiri pa kuuma kwa kukhudzana pakati pa zigawozo.
Kukhudza kulondola kwa muyeso Kukula kwapamwamba kwa gawo loyezera la gawolo ndi malo oyezera a chida choyezera kudzakhudza mwachindunji kulondola kwa kuyeza, makamaka muyeso yolondola.
Komanso, pamwamba roughness adzakhala ndi milingo yosiyana ❖ kuyanika, matenthedwe madutsidwe ndi kukana kukhudzana, kuwonetsera mphamvu ndi ma radiation mbali, kukana kutuluka kwa zakumwa ndi mpweya, ndi kutuluka kwa panopa padziko kondakitala. .
