Ukususa iiMicroburrs kwiMisonto eDiameter encinci |UPhando lwebrashi Mfg.

Ukuba ufunda iiforam ze-intanethi uyazi ukuba kukho iingxoxo ezininzi malunga nokuchonga eyona ndlela ilungileyo yokususa iibhura ezingenakuthintelwa ezenziwe ngexesha lokwenziwa kweendawo ezinemisonto.Imisonto yangaphakathi – nokuba isikiwe, isongiwe okanye yenziwe ngokubanda – isoloko ineentsimbi ekungeneni nasekuphumeni emngxunyeni, kwiikresti zemisonto, nakuninzi lwencam zokubeka.Imisonto yangaphandle kwiibholithi, izikrufu, kunye nezikhonkwane ezinemiba efanayo – ngakumbi ekuqaleni komsonto.

Kwimisonto emikhulu, i-burrs inokususwa ngokuphinda ilandele indlela yokusika, kodwa oku kwandisa ixesha lokujikeleza kwinxalenye nganye.Imisebenzi yesibini, efana nezixhobo zokucima inayiloni enzima okanye iibrashi zebhabhathane nazo zingasetyenziswa.cnc machining inxalenye

Nangona kunjalo, imiceli mngeni yonyuka kakhulu xa i-diameter ye-threaded part okanye imingxunya echotshiweyo ilinganisa ngaphantsi kwe-0.125 in. Kwezi meko, ii-microburrs zisadalwa kodwa zincinci ngokwaneleyo ukuba ukushenxiswa kungumcimbi wokupolisha kunokugxothwa ngokuqatha.

Ngeli xesha, kuluhlu oluncinci, ukhetho lwezisombululo zokuqhawula luyancipha kakhulu.Izindlela zokugqiba ubuninzi zingasetyenziselwa, ezifana nokuwa, i-electrochemical polishing kunye ne-thermal deburring, kodwa ezi zifuna ukuba iindawo zithunyelwe ngaphandle kweendleko ezongezelelweyo kunye nokulahlekelwa kwexesha.

Kwiivenkile ezininzi zoomatshini kukhethwa ukuba kugcinwe imisebenzi yesibini endlwini, kubandakanywa ukubhatalwa, nokuba kukusebenzisa oomatshini be-CNC, okanye ngokusebenzisa iidrili zezandla, okanye ubuchule bezandla.inxalenye yeplastiki

Kwezi meko kukho iibhrashi ezincinci ezithi — ngaphandle kwesiqu esincinci, iifilaments kunye nemilinganiselo yonke – zinokujikeleziswa kusetyenziswa uqheliso lwezandla kunye nokusebenzisa iadaptha kwisixhobo se-CNC.Ngoku ifumaneka nge-nylon ene-abrasive, i-carbon steel, insimbi engenasici kunye ne-diamond-abrasive filaments, ezi zixhobo zifumaneka zincinci njenge-0.014, kuxhomekeke kuhlobo lwe-filament.

Ngenxa yokuba kunokwenzeka ukuba i-burrs ichaphazele ifom, ukufaneleka okanye ukusebenza kwemveliso, izibonda ziphezulu kwiimveliso ezineentambo ezincinci, kubandakanywa iindawo zeewotshi, iiglasi zamehlo, iiselfowuni, iikhamera zedijithali, iibhodi zesekethe eziprintiweyo, izixhobo zonyango ezichanekileyo, kunye iindawo ze-aerospace.Imingcipheko ibandakanya ukungahambi kakuhle kwamalungu adityanisiweyo, ubunzima ekuhlanganiseni, iibhula ezinokukhululeka kwaye zingcolise iinkqubo zococeko, kunye nokungaphumeleli kwe-fasteners ebaleni.

Ubuchwephesha bokugqiba ubunzima —Iindlela zokugqiba ubuninzi obufana nokuwa, ukukhutshwa kwe-thermal kunye nokupolishwa kwe-electrochemical kunokusebenza ekususeni ezinye iibhula ezikhanyayo kwiindawo ezincinci.Ukugingqika, umzekelo, kunokusetyenziselwa ukususa ezinye iibhula kodwa ayisebenzi ngokubanzi kwiziphelo zemisonto.Ngaphaya koko, ukhathalelo luyafuneka ukuze kuthintelwe i-burrs yokudibanisa kwiintlambo zentambo, ezinokuthi ziphazamise ukudibanisa.

Xa i-burrs ikwimisonto yangaphakathi, ubuchule bokugqiba ubunzima kufuneka bukwazi ukufikelela nzulu kwizakhiwo zangaphakathi.inxalenye yobhedu

Ukukhupha i-thermal, umzekelo, isebenzisa amandla obushushu asondela kumawaka aliqela degrees Fahrenheit ukuhlasela iiburrs macala onke.Ngenxa yokuba ubushushu abukwazi ukufuduka ukusuka kwibhar ukuya kwisixhobo somzali, i-burr itshiswa kuphela kwisixhobo somzali.Ngaloo ndlela, ukuchithwa kwe-thermal akuchaphazeli nayiphi na imilinganiselo, ukugqitywa komphezulu, okanye iimpawu eziphathekayo zenxalenye yomzali.

I-electrochemical polishing nayo isetyenziselwa ukuchithwa kwaye isebenza ngokulinganisa nayiphi na i-micro-peaks okanye i-burrs.Nangona ubuchule busebenza, kusekho inkxalabo yokuba inokuchaphazela imisonto.Sekunjalo, ngokuqhelekileyo, ukususwa kwezinto kuhambelana nokumila kwenxalenye.

Ngaphandle kwemiba enokubakho, ixabiso eliphantsi lokugqiba ngobuninzi lisayenza ibe yinkqubo enomtsalane kwezinye iivenkile zoomatshini.Nangona kunjalo, njengoko sele kuphawuliwe, iivenkile zoomatshini zikhetha ukugcina imisebenzi yesibini ngaphakathi endlwini ukuba kunokwenzeka.

Iibhrashi zokucima i-miniature — Kwiindawo ezinemisonto kunye nemingxuma eyenziwe ngoomatshini engaphantsi kwe-0.125 ngaphakathi.Iibhrashi ezincinci ziza kwiisayizi ezincinci ezahlukeneyo (kubandakanya iikiti), iikhonto kunye nemathiriyeli.Ezi zixhobo zifaneleke kakhulu ukujongana nokunyamezela okuqinileyo, ukudibanisa komphetho, ukuchithwa kunye nezinye iimfuno zokugqiba.

“Iivenkile zoomatshini ziza kuthi zifuna iibhrashi ezincinci kuba azifuni kukhupha amalungu kwakhona kwaye zifuna ukwenza loo msebenzi ngaphakathi,” utshilo uJonathan Borden, umphathi wezentengiso kuzwelonke weBrush Research Manufacturing.“Ngebrashi encinci, abasenaxhala lamaxesha okukhokela kunye nolungelelwaniso olongezelelweyo lokuthumela iinxalenye kunye nokuzibuyisela ngaphakathi.

Njengomthengisi ogcweleyo wezisombululo zokugqiba umphezulu, i-BRM inikezela ngeebhrashi zokucoca ezincinci kwiintlobo ngeentlobo zefilament kunye nezimbo zeengcebiso.Eyona brashi incinci yedayamitha yenkampani ilinganisa kuphela i-0.014 kwi.

Iibrashi ezincinci zokuqhawula zingasetyenziswa ngesandla.Nangona kunjalo, ngenxa yokuba iingcingo ze-brush stem zilungile kakhulu kwaye zinokugoba, umphuhlisi ucebisa ukusebenzisa i-pin-vise.I-BRM inikezela nge-pin-end-pin vise kwiikhithi ukuya kuthi ga kwi-12 iibhrashi kuzo zombini idesimali (0.032 ukuya ku-0.189 in.) kunye nobukhulu bomngxuma we-metric (1 mm ukuya kwi-6.5 mm).

I-pin i-vises ingasetyenziselwa ukubamba iibrashi ezincinci ze-diameter ukuzivumela ukuba zijikelezwe phantsi kombane kwi-drill ephathwayo kunye nakumatshini we-CNC.

Iibrashi ezincinci nazo zingasetyenziswa kwimisonto yangaphandle, ukususa iibhula ezincinci ezinokuvela ekuqaleni komsonto.Ezi burrs zinokubangela iingxaki kwaye kufuneka zisuswe, kuba nasiphi na isinyithi esisusiweyo sinokubangela iimeko ezinzima nezinokuba yingozi kwizicelo zemizi-mveliso ezifuna ukuchaneka okukhethekileyo kunye nococeko.

Ukuthintela ukuphambuka kwesiqu socingo olujijekileyo lwebrashi, izixhobo ze-CNC zinokucwangciswa ukuba zisebenzise uxinzelelo oluchanekileyo kunye nesantya sokujikeleza.

“Ezi ntlobo zemisebenzi yokuhlawulela - nkqu neebrashi ezincinci zedayamitha ezincinci – ziyakwazi ukuzenzela,†utshilo uBorden.“Ungasebenzisa izixhobo koomatshini be-CNC usebenzisa i-pin vise okanye ngokwenza iadaptha.

Kukho iintlobo ezininzi zeebrashi ezincinci ezikhoyo namhlanje ezingahlukanga nje ngobukhulu, kodwa kunye nohlobo lwefilament.Intsimbi yekhabhoni, insimbi engenasici, ubhedu, inayiloni kunye nenayiloni egcwele abrasive zisetyenziswa ngokuqhelekileyo.Inayiloni ezaliswe yi-Abrasive inokuba ne-silicon carbide, i-aluminiyam oxide, okanye i-diamond abrasive.

Ngokuka-Borden, inayiloni eqhotyozayo isebenza ngokukodwa ekususeni ii-burrs kunye neencopho zemisonto yokupolisha kunye ne-flank angles kwimingxunya ye-aluminiyam echothiweyo.“Ukuba usike umsonto onenqaku elinye kwi-aluminiyam okanye inxalenye ibithungelwe kusetyenziswa isixhobo sedayimane, kuya kubakho ‘fuzz’ kunye neengile ezirhabaxa zeflanki ezifuna ukukhazimliswa, utshilo.

Iibhrashi zentsimbi ezincinci ezincinci zithandwa ngokugruzuka okuthe kratya kwemathiriyeli efana nentsimbi etyhidiweyo okanye intsimbi, ukususa iitshiphusi okanye iibhula ezicacileyo.Nangona iibhrashi ezincinci zenayiloni ezibolileyo zifumaneka zincinci njenge 0.032 in., ngenxa yobume bensimbi engenasici ye-BRM ngoku ibonelela ngeesayizi ezintathu ezincinci zebhrashi: 0.014, 0.018, kunye ne-0.020 kwi.

Ikwabonelela ngeebrashi ezincinci zokuqhawula ezinemicu yedayimane-abrasive kwimathiriyeli eqinile, njengentsimbi eqinisiweyo, i-ceramic, iglasi, kunye nealloys ye-aerospace.

“Ukhetho lwefilamenti luxhomekeke kwingcaciso yokugqiba komphezulu, okanye ukuba kukho imfuneko yamandla agqwashu kakhulu okucima,†utshilo uBorden.

Wongeze ukuba ezinye izinto ezisetyenziswa kwiibhrashi ezincinci ezisetyenziswa kwizicelo ezizenzekelayo ziquka i-RPM yesixhobo somatshini, amazinga okutya, kunye ne-optima;ukunxiba-ubomi.

Nangona ukukhutshwa kwemisonto emincinci yangaphakathi nangaphandle kunokuba ngumceli mngeni, ukusebenzisa ezona zixhobo zifanelekileyo kwisicelo esinikiweyo kunokuwenza lula umsebenzi kwaye uqinisekise ukuba zonke ii-burrs zisuswa rhoqo kwindawo nganye.Ukongezelela, ngokugwema ukukhutshwa kwemisebenzi yesibini, izitolo zoomatshini zinganciphisa ixesha lokuguqula kunye nexabiso ngenxalenye nganye.UJeff Elliott nguTorrance, umbhali wezobugcisa waseCalif.Igalelo lakhe lamva nje kwi-AmericanMachinist.com libandakanya i-CBN Hones yokuPhucula uMphezulu wokuQeda kuMacandelo eSuperalloy kunye nePlanar Honing ibonelela ngeAngle eNtsha yokuQeda uMphezulu.
