Kuchotsa Ma Microburrs kuchokera ku Ulusi Wang'ono Wam'mimba mwake | Brush Research Mfg.

Mukawerenga mabwalo apaintaneti mumadziwa kuti pali kutsutsana kwakukulu pakupeza njira yabwino yochotsera ma burrs osapeweka omwe amapangidwa popanga zida zomata. Ulusi wamkati – kaya wodulidwa, wogudubuzika kapena wozizira – nthawi zambiri umakhala ndi timabowo polowera mabowo ndi potuluka, pa ulusi wa ulusi, ndi m’mbali zambiri. Ulusi wakunja pa mabawuti, zomangira, ndi zopota nazo zili ndi zofanana – makamaka kumayambiriro kwa ulusi.

Pazigawo zokulirapo, ma burrs amatha kuchotsedwa potsata njira yodulira, koma izi zimawonjezera nthawi yozungulira gawo lililonse. Ntchito zachiwiri, monga zida zonyamulira nayiloni zolemera kapena maburashi agulugufe zingagwiritsidwenso ntchito.cnc Machining gawo

Komabe, zovuta zimawonjezeka kwambiri pamene kukula kwa gawo lopangidwa ndi ulusi kapena mabowo oponyedwa akucheperachepera 0.125 mkati. Muzochitika izi, ma microburrs amapangidwabe koma ndi ochepa kwambiri moti kuchotsa ndi nkhani yopukutidwa kusiyana ndi kuwononga mwamphamvu.

Panthawi imeneyi, m'magulu ang'onoang'ono, kusankha kwa njira zowonongeka kumachepa kwambiri. Njira zomaliza zambiri zingagwiritsidwe ntchito, monga kugwa, kupukuta kwa electrochemical ndi kutentha kwa kutentha, koma izi zimafuna kuti ziwalozo zitumizidwe pamtengo wowonjezera komanso kutaya nthawi.

Kwa malo ogulitsa makina ambiri ndikwabwino kusungitsa ntchito zina m'nyumba, kuphatikiza kubweza, mwina pogwiritsa ntchito makina a CNC, kapena kubowola pamanja, kapenanso njira zamanja.pulasitiki gawo

Pazochitikazi pali maburashi ang'onoang'ono omwe — ngakhale ali tsinde laling'ono, ulusi ndi miyeso yonse - amatha kusinthasintha pogwiritsa ntchito kubowola pamanja komanso kugwiritsa ntchito ma adapter pazida za CNC. Tsopano akupezeka ndi abrasive nayiloni, carbon steel, zitsulo zosapanga dzimbiri ndi diamondi-abrasive filaments, zida zimenezi zilipo ang'onoang'ono monga 0.014 mu., malingana ndi mtundu filament.

Chifukwa cha kuthekera kwa ma burrs kukhudza mawonekedwe, kukwanira kapena kugwira ntchito kwa chinthu, mitengo yake ndi yayikulu pazinthu zomwe zili ndi ulusi yaying'ono, kuphatikiza mawotchi, magalasi, mafoni am'manja, makamera a digito, ma board osindikizidwa, zida zamankhwala zolondola, ndi mbali zamlengalenga. Zowopsazi zimaphatikizapo kusalinganika bwino kwa ziwalo zolumikizana, zovuta pakusonkhana, ma burrs omwe amatha kutayikira ndikuyipitsa machitidwe aukhondo, komanso kulephera kwachangu m'munda.

Njira zomaliza misa —Njira zomalizitsa misa monga kugwa, kuwotcha kwamafuta ndi kupukuta kwa electrochemical zitha kukhala zogwira mtima pochotsa ma burrs opepuka pazigawo zing'onozing'ono. Kugwetsa, mwachitsanzo, kutha kugwiritsidwa ntchito pochotsa ma burrs koma sikumagwira ntchito kumapeto kwa ulusi. Kuphatikiza apo, kusamala kumafunika kuti tipewe kupukuta ma burrs mu zigwa za ulusi, zomwe zingasokoneze kusonkhana.

Pamene ma burrs ali pa ulusi wamkati, njira zomalizitsa misala ziyenera kufika mozama mkati mwazinthu zamkati.gawo la mkuwa

Kutentha kwamafuta, mwachitsanzo, kumagwiritsa ntchito mphamvu ya kutentha yomwe imayandikira madigiri zikwi zingapo Fahrenheit kuti iwononge ma burrs kuchokera kumbali zonse. Chifukwa kutentha sikungasunthike kuchoka ku burr kupita ku zinthu za makolo, burr amangotenthedwa mpaka kuzinthu za makolo. Chifukwa chake, kutenthetsa kwamafuta sikumakhudza kukula kulikonse, kumaliza kwapamwamba, kapena zinthu za gawo la kholo.

Electrochemical polishing imagwiritsidwanso ntchito poboola ndipo imagwira ntchito pochotsa nsonga zazing'ono zilizonse kapena ma burrs. Ngakhale kuti njirayi ndi yothandiza, palinso nkhawa kuti ikhoza kukhudza ulusi. Komabe, kawirikawiri, kuchotsa zinthu kumagwirizana ndi mawonekedwe a gawolo.

Ngakhale pali zovuta zomwe zingatheke, kutsika mtengo kwa kutsirizitsa kwakukulu kumapangitsabe kukhala njira yabwino kwa ogulitsa makina. Komabe, monga taonera kale, masitolo ogulitsa makina amakonda kusunga ntchito zina m'nyumba ngati n'kotheka.

Maburashi ang'onoang'ono obowola — Pazigawo zomangika ndi mabowo opangidwa ndi makina osakwana 0.125 in., maburashi azitsulo ang'onoang'ono ndi chida chotsika mtengo chochotsera ma burrs ang'onoang'ono ndikupukuta mkati. Maburashi ang'onoang'ono amabwera mosiyanasiyana ting'onoting'ono (kuphatikiza zida), ma contour ndi zida. Zida izi ndizoyenera kwambiri kuthana ndi kulolerana kolimba, kusakanikirana kwa m'mphepete, kubweza ndi zina zofunika kumaliza.

"Masitolo amakina amabwera kwa ife kudzafuna maburashi ang'onoang'ono chifukwa sakufunanso kutulutsa zidazo ndipo akufuna kugwira ntchito m'nyumba," adatero Jonathan Borden, woyang'anira malonda ku Brush Research Manufacturing. âNdi kaburashi kakang'ono, sakhalanso ndi nkhawa za nthawi yotsogolera komanso kulumikizana kwina kuti atumize magawo ndikuwabweretsanso.

Monga ogulitsa mzere wathunthu wazomaliza, BRM imapereka maburashi ang'onoang'ono ochotsa mumitundu yosiyanasiyana ya ulusi ndi masitaelo ansonga. Burashi yaying'ono kwambiri yamakampani imakhala ndi mainchesi 0.014 okha.

Maburashi ang'onoang'ono a deburring amatha kugwiritsidwa ntchito pamanja. Komabe, chifukwa mawaya a tsinde la burashi ndi abwino kwambiri ndipo amatha kupindika, wopanga amalimbikitsa kugwiritsa ntchito pini-vise. BRM imapereka pini yomaliza pawiri mu zida zokhala ndi maburashi ofika 12 mu decimal zonse (0.032 mpaka 0.189 mkati) ndi kukula kwa dzenje (1 mm mpaka 6.5 mm).

Ma pin vise amathanso kugwiritsidwa ntchito kugwira maburashi ang'onoang'ono ang'onoang'ono kuti azitha kuzunguliridwa ndi mphamvu pa kubowola kwa m'manja ngakhalenso pamakina a CNC.

Maburashi ang'onoang'ono amathanso kugwiritsidwa ntchito pazingwe zakunja, kuchotsa tinthu tating'onoting'ono tomwe timapanga poyambira ulusi. Ma burrs awa angayambitse mavuto ndipo ayenera kuchotsedwa, chifukwa zitsulo zilizonse zomwe zasamutsidwa zimatha kuyambitsa zovuta komanso zowopsa pamafakitale omwe amafunikira kulondola komanso ukhondo wapadera.

Pofuna kupewa kupotoza kwa tsinde la waya wokhotakhota wa burashi, zida za CNC zitha kukonzedwa kuti zigwiritse ntchito kuthamanga kwake komanso liwiro lozungulira.

“Mitundu yowombola iyi – ngakhale mutakhala ndi maburashi aang`ono ang'onoang'ono ang'onoang'ono – amatha kukhala ongochita zokha,†adatero Borden. “Mutha kugwiritsa ntchito zida zamakina a CNC pogwiritsa ntchito pin vise kapena popanga adaputala.

Pali mitundu ingapo ya maburashi ang'onoang'ono omwe alipo lero omwe amasiyana osati kukula kwake, komanso mtundu wa filament. Chitsulo cha kaboni, chitsulo chosapanga dzimbiri, mkuwa, nayiloni ndi nayiloni yodzaza ndi abrasive imagwiritsidwa ntchito kwambiri. Nayiloni yodzaza ndi abrasive ikhoza kukhala ndi silicon carbide, aluminium oxide, kapena abrasive diamondi.

Malinga ndi a Borden, nayiloni yonyezimira ndiyothandiza kwambiri pochotsa nsonga ndi kupukuta nsonga za ulusi ndi m'mphepete mwa mabowo ojambulidwa ndi aluminiyamu. “Ngati mudula ulusi wa nsonga imodzi mu aluminiyamu kapena mbaliyo idalumikizidwa pogwiritsa ntchito zida za diamondi, padzakhala ‘fuzz’ zambiri ndi ngodya za m`mbali za ulusi zomwe ziyenera kupukutidwa,â adalongosola motero.

Maburashi achitsulo osapanga dzimbiri ang'onoang'ono ndi otchuka chifukwa chochotsa zinthu mwankhanza kwambiri ngati chitsulo chonyezimira kapena chitsulo, kuchotsa tchipisi kapena kupukuta ma burrs. Ngakhale maburashi ang'onoang'ono a nayiloni abrasive amapezeka ang'onoang'ono ngati 0.032 mkati, chifukwa cha mtundu wa chitsulo chosapanga dzimbiri BRM tsopano ikupereka maburashi ang'onoang'ono atatu: 0.014, 0.018, ndi 0.020 in.

Amaperekanso maburashi ang'onoang'ono onyamulira okhala ndi ulusi wonyezimira wa diamondi pazinthu zolimba, monga chitsulo cholimba, ceramic, magalasi, ndi ma alloys amlengalenga.

“Kusankha kwa ulusi kumatengera mawonekedwe a pamwamba, kapena ngati pakufunika mphamvu yamphamvu yochotsamo,†adatero Borden.

Anawonjezeranso kuti zinthu zina zomwe zimagwiritsa ntchito maburashi ang'onoang'ono omwe amagwiritsidwa ntchito popanga makina opangira makina ndi RPM ya chida cha makina, mitengo ya chakudya, ndi kukwanira; kuvala moyo.

Ngakhale kuchotsa ulusi wamkati ndi wakunja kungakhale kovuta, kugwiritsa ntchito zida zoyenera kwambiri pa pulogalamu yomwe mwapatsidwa kumatha kufewetsa ntchitoyi ndikutsimikizira kuti ma burrs onse amachotsedwa nthawi zonse. Kuonjezera apo, popewa kutulutsidwa kwa ntchito zachiwiri zowonongeka, masitolo ogulitsa makina amatha kuchepetsa nthawi yosinthira ndi mtengo pa gawo lililonse.Jeff Elliott ndi Torrance, Calif.-based technical writer.
