Ho Tlosa Li-Microburrs ho Likhoele tse Nyenyane tsa Diameter | Brush Research Mfg.

Haeba u bala liforomo tsa marang-rang ua tseba hore ho na le phehisano e ngata mabapi le ho tseba mokhoa o nepahetseng oa ho tlosa li-burrs tse ke keng tsa qojoa tse entsoeng nakong ea machining ea likarolo tse lohiloeng. Likhoele tse ka hare – ebang li sehiloe, li pitikolohile kapa li entsoe ka mokhoa o batang – hangata li na le litsupa menyakong le moo ho tsoang teng, holim’a likhoele, le mathōkong a mangata. Likhoele tsa ka ntle holim'a liboutu, likurufu, le li-spindle li na le litaba tse tšoanang – haholo-holo qalong ea khoele.

Bakeng sa likarolo tse kholoanyane, li-burrs li ka tlosoa ka ho ts'oara tsela ea ho itšeha hape, empa sena se eketsa nako ea potoloho bakeng sa karolo ka 'ngoe. Ts'ebetso ea bobeli, joalo ka lisebelisoa tse boima tsa nylon kapa borashe ba serurubele le tsona li ka sebelisoa.karolo ea machining ea cnc

Leha ho le joalo, liqholotso li eketseha haholo ha bophara ba karolo e khoeleng kapa masoba a tapped a le ka tlase ho 0.125 in. Maemong ana, li-microburrs li ntse li bōptjoa empa li nyenyane hoo ho tlosoa e leng taba ea ho belisoa ho feta ho senya ka mabifi.

Ka nako ena, maemong a manyane, khetho ea litharollo tsa deburring e fokotseha haholo. Mekhoa ea ho qeta boima e ka sebelisoa, e kang ho oela, ho belisoa ha electrochemical le thermal deburring, empa tsena li hloka hore likarolo li romelloe ka litšenyehelo tse eketsehileng le tahlehelo ea nako.

Bakeng sa mabenkele a mangata a mechini, ho molemo ho boloka ts'ebetso ea bobeli ka tlung, ho kenyelletsa le ho e tlosa, ebang ke ka ho sebelisa mochini oa CNC, kapa ka ho cheka ka letsoho, kapa mekhoa ea matsoho.karolo ea polasetiki

Mekhoa ea ho qeta bongata — Mekhoa ea ho qeta bongata e kang ho oa, ho tlosa mocheso le ho bentša ka electrochemical e ka sebetsa hantle bakeng sa ho tlosa li-burrs tse khanyang likarolong tse nyenyane. Ho tea mohlala, ho ka sebelisoa ho tlosa li-burrs empa hangata ha e sebetse lipheletsong tsa likhoele. Ho feta moo, tlhokomelo e ea hlokahala ho thibela mashing burrs hore e be likhohlo tsa likhoele, tse ka sitisang kopano.

Leha ho na le mathata a ka bang teng, theko e tlase ea ho qeta bongata e ntse e etsa hore e be mokhoa o ipiletsang bakeng sa mabenkele a mang a mochini. Leha ho le joalo, joalo ka ha ho boletsoe, mabenkele a mochini a khetha ho boloka ts'ebetso ea bobeli e le ka tlung haeba ho khonahala.

Li-brushes tse nyane tse etsang li-deburring — Bakeng sa likarolo tse khoele le masoba a entsoeng ka mochini a ka tlase ho 0.125 in., maborashe a tšepe a manyane ke sesebelisoa se theko e tlase sa ho tlosa li-burrs tse nyane le ho bentša ka hare. Li-brushes tse nyane li tla ka boholo bo fapaneng (ho kenyeletsoa le lisebelisoa), li-contours le lisebelisoa. Lisebelisoa tsena li loketse ka ho fetisisa ho sebetsana le mamello e tiileng, ho kopanya ka bohale, ho senya le litlhoko tse ling tsa ho qetela.

"Mabenkele a mechini a tla ho rona bakeng sa borashe bo bonyenyane hobane ha ba sa batla ho fana ka likarolo mme ba batla ho etsa mosebetsi oo ka tlung," ho boletse Jonathan Borden, mookameli oa thekiso ea naha bakeng sa Brush Research Manufacturing. “Ka borashe bo bonyenyane, ha ba sa tlameha ho tšoenyeha ka linako tse etellang pele le khokahanyo e eketsehileng ho romela likarolo le ho li khutlisa.

Joaloka morekisi ea fanang ka litharollo tsa ho qeta holimo, BRM e fana ka borashe bo bonyenyane ba mefuta e fapaneng ea likhoele le mekhoa ea malebela. Brashi e nyane ka ho fetisisa ea bophara ba k'hamphani e lekanya feela 0.014 in.

Li-brushes tse nyenyane tse senyang li ka sebelisoa ka letsoho. Leha ho le joalo, hobane lithapo tsa "brashi stem" li ntle haholo 'me li ka kobeha, moqapi o khothaletsa ho sebelisa pin-vise. BRM e fana ka phini e nang le mahlakore a mabeli ka li-kits tse nang le borashe ba ho fihla ho 12 ho li-decimal ka bobeli (0.032 ho isa ho 0.189 in.) le boholo ba lesoba la metric (1 mm ho isa ho 6.5 mm).

Li-brushes tse nyane le tsona li ka sebelisoa likhoeleng tse kantle, ho tlosa likhoele tse nyane tse ka bang teng qalong ea khoele. Li-burrs tsena li ka baka mathata 'me li lokela ho tlosoa, hobane tšepe efe kapa efe e tlositsoeng e ka baka maemo a kotsi le a kotsi lits'ebetsong tsa indasteri tse hlokang ho nepahala le bohloeki bo ikhethang.

Ho thibela ho kheloha ha kutu ea terata e sothehileng ea borashe, lisebelisoa tsa CNC li ka hlophisoa ho sebelisa khatello e nepahetseng le lebelo la ho potoloha.

“Mefuta ena ya ditshebetso - esita le ka borashe bo bonyenyane ba bophara bo boholo – e ka iketsetsa,†ho boletse Borden. “U ka sebelisa lisebelisoa tse mochining oa CNC u sebelisa pin vise kapa ka ho etsa adaptara.
