Kuchotsa ma Microburrs kuchokera ku Small

Pali mkangano waukulu pamabwalo apaintaneti okhudza njira zabwino kwambiri zochotsera ma burrs omwe amapangidwa popanga zida za ulusi. Ulusi wamkati—kaya wodulidwa, wopindidwa, kapena wozizira—kaŵirikaŵiri umakhala ndi ting'onoting'ono pazipata ndi potulukira mabowo, pamipando ya ulusi, ndi m'mphepete mwake. Ulusi wakunja wa pa mabawuti, zomangira, ndi zopota zimakumana ndi zofanana, makamaka kumayambiriro kwa ulusi.

 

Pazigawo zokulirapo, ma burrs amatha kuchotsedwa potsata njira yodulira; komabe, njirayi imawonjezera nthawi yozungulira gawo lililonse. Ntchito zachiwiri, monga kugwiritsa ntchito zida zolemetsa za nayiloni kapena maburashi agulugufe, ziliponso.

 

Zovuta zimakula kwambiri mukamagwira ntchito ndi ulusi kapena mabowo okhomedwa omwe amalemera zosakwana mainchesi 0.125 m'mimba mwake. Pazifukwa izi, ma micro-burrs amapangidwa kuti ndi ang'onoang'ono mokwanira kuti amafunikira kupukuta m'malo mothamangitsidwa mwaukali.

 

Pazigawo zing'onozing'ono, zosankha zochotsera ndalama zimakhala zochepa. Ngakhale njira zomaliza zambiri monga kugwa, kupukuta kwa electrochemical, ndi kuwotcha kwamafuta kumatha kukhala kothandiza, njirazi nthawi zambiri zimafuna kutumiza ziwalozo, zomwe zimawononga ndalama zowonjezera komanso nthawi.

 

Malo ogulitsa makina ambiri amakonda kusunga ntchito zachiwiri m'nyumba, kuphatikiza kubweza, potengera makina opangira makina a CNC kapena kugwiritsa ntchito kubowola pamanja ndi njira zamanja. Pali maburashi ang'onoang'ono omwe, ngakhale timiyendo tating'ono komanso kukula kwake, amatha kuyendetsedwa ndi kubowola pamanja kapena kusinthidwa kuti agwiritsidwe ntchito ndi zida za CNC. Zida zimenezi zimabwera ndi nayiloni yonyezimira, chitsulo cha kaboni, chitsulo chosapanga dzimbiri, ndi ulusi wa diamondi-abrasive, ndipo chaching'ono kwambiri chimakhala mainchesi 0.014, kutengera mtundu wa ulusi.

 

Chifukwa cha kuthekera kwa ma burrs kukhudza mawonekedwe, kukwanira, kapena kugwira ntchito kwa chinthu, mitengoyo ndi yayikulu pazinthu zomwe zili ndi tinthu tating'onoting'ono, kuphatikiza magawo a ulonda, magalasi amaso, mafoni am'manja, makamera a digito, matabwa osindikizira, zida zamankhwala zolondola, ndi zigawo zazamlengalenga. Zowopsa zimaphatikizapo kusalumikizana bwino kwa magawo olumikizana, zovuta zapagulu, kuthekera kwa ma burrs kukhala otayirira ndikuyipitsa machitidwe aukhondo, ngakhale kulephera kwa zomangira m'munda.

 

Njira zomaliza zambiri monga kugwa, kutulutsa kutentha, ndi kupukuta kwa electrochemical kumatha kukhala kothandiza pochotsa zowunikira pazigawo zing'onozing'ono. Mwachitsanzo, kugwa kungathandize kuchotsa nsonga zina, koma nthawi zambiri sikuthandiza kumapeto kwa ulusi. Kuonjezera apo, kuyenera kuchitidwa mosamala kuti musaphatikize ma burrs mu zigwa za ulusi, zomwe zingasokoneze kusonkhanitsa.

 

Pamene ma burrs alipo pa ulusi wamkati, njira zomalizitsa misala ziyenera kufika mozama mkati mwazinthu zamkati. Kutentha kotentha kumagwiritsa ntchito mphamvu ya kutentha yomwe imatha kufika madigiri zikwi zingapo Fahrenheit kuchotsa ma burrs mbali zonse. Chifukwa kutentha sikungasunthike kuchoka ku burr kupita ku zinthu za makolo, burr amangotenthedwa mpaka kufika pamlingo wa zinthu za kholo. Zotsatira zake, kutentha kwa kutentha sikukhudza kukula, kutsirizika kwapamwamba, kapena katundu wa gawo la kholo.

 

Electrochemical polishing ndi njira ina yomwe imagwiritsidwa ntchito pochotsa, kugwira ntchito pochotsa nsonga zazing'ono kapena ma burrs. Ngakhale kuti n'zothandiza, pali nkhawa zina kuti njira iyi ingakhudze madera omwe ali ndi ulusi. Komabe, kaŵirikaŵiri kuchotsa zinthu kumagwirizana ndi mmene mbaliyo imaonekera.

 

Ngakhale pali zovuta zomwe zingatheke, kutsika mtengo komaliza kumapangitsa kuti zikhale zokopa kwa ogulitsa makina ena. Komabe, malo ogulitsa makina ambiri amakonda kusunga ntchito zachiwiri m'nyumba ngati kuli kotheka.

 

Pazigawo zomangika ndi mabowo opangidwa ndi makina ochepera mainchesi 0.125, maburashi azitsulo ang'onoang'ono amakhala ngati zida zotsika mtengo zochotsera tinthu tating'onoting'ono ndikupukuta mkati. Maburashi awa amabwera m'miyeso yocheperako, ma contours, ndi zida, kuwapangitsa kukhala oyenera kulolerana molimba, kuphatikiza m'mphepete, kuwotcha, ndi zina zofunika kumaliza.

 

Monga ogulitsa mzere wathunthu wazomaliza, ANEBON imapereka maburashi ang'onoang'ono odulira mumitundu yosiyanasiyana ya ulusi ndi masitayelo ansonga, ndi burashi yaying'ono kwambiri yotalika mainchesi 0.014.

 

Ngakhale maburashi ang'onoang'ono atha kugwiritsidwa ntchito pamanja, tikulimbikitsidwa kugwiritsa ntchito pin vise chifukwa mawaya a tsinde la burashi ndi osalimba ndipo amatha kupindika. ANEBON imapereka ma pini awiri omaliza mu zida zomwe zimaphatikizapo maburashi mpaka 12 mu decimal (0.032 mpaka 0.189 mainchesi) ndi makulidwe a metric (1 mm mpaka 6.5 mm).

 

Ma pini awa amathanso kugwiritsidwa ntchito kugwira maburashi ang'onoang'ono, kuwalola kuti azizunguliridwa ndi kubowola m'manja kapena kusinthidwa kuti agwiritse ntchito pamakina a CNC.
