Ukukhipha Ama-Microburrs Kuchungechunge Oluncane Lobubanzi | Ibhulashi Ucwaningo Mfg.

Uma ufunda izinkundla eziku-inthanethi uyazi ukuthi kunenkulumompikiswano enkulu mayelana nokuhlonza indlela efanele yokususa ama-burrs angenakugwemeka adalwe ngesikhathi somshini wezingxenye ezinentambo. Imicu yangaphakathi – kungakhathaliseki ukuthi isikiwe, igoqiwe noma yakhiwe ngendlela ebandayo – ivamise ukuba namaqhuqhuva ezindaweni zokungena nezintuba zokuphuma, kuma-thread crests, kanye nasemaphethelweni amaningi. Imicu yangaphandle kumabhawodi, izikulufu, namaphotha anezinkinga ezifanayo – ikakhulukazi ekuqaleni kochungechunge.

Ezingxenyeni ezinkulu ezinentambo, ama-burrs angasuswa ngokulandela kabusha indlela yokusika, kodwa lokhu kwandisa isikhathi somjikelezo wengxenye ngayinye. Imisebenzi yesibili, njengamathuluzi okukhipha inayiloni esindayo noma amabhulashi ovemvane nawo angasetshenziswa.cnc machining ingxenye

Kodwa-ke, izinselele zikhula kakhulu uma ububanzi bengxenye ecushiwe noma izimbobo ezithenjiwe zikala ngaphansi kuka-0.125 in. Kulezi zimo, ama-microburrs asakhiwa kodwa mancane ngokwanele ukuthi ukususwa kuyindaba yokupholishwa kunokudebhula okunamandla.

Kuleli qophelo, kububanzi obuncane, ukukhetha kwezixazululo zokukhipha imali kuncipha kakhulu. Izindlela zokuqeda inqwaba zingasetshenziswa, njengokuwa, ukupholisha nge-electrochemical kanye nokususa ukushisa, kodwa lokhu kudinga ukuthi izingxenye zithunyelwe ngezindleko ezengeziwe kanye nokulahlekelwa isikhathi.

Ezitolo eziningi zemishini kungcono ukugcina imisebenzi yesibili endlini, okuhlanganisa nokukhipha imali, ngokuthatha ama-automation kusetshenziswa imishini ye-CNC, noma ngokusebenzisa ukubhola ngesandla, noma ngisho namasu okwenziwa ngesandla.ingxenye yepulasitiki

Kulezi zimo kukhona amabhulashi amancane — naphezu kwesiqu esincane, imicu kanye nobukhulu obuphelele – angakwazi ukuzungeziswa kusetshenziswa izimbobo zezandla ngisho nokusebenzisa ama-adaptha kumpahla ye-CNC. Manje itholakala ngenayiloni ebrasive, i-carbon steel, insimbi engagqwali nemicu yedayimane, lawa mathuluzi atholakala amancane njengo-0.014 in., kuye ngohlobo lwefilament.

Uma kubhekwa amandla okuthi ama-burrs athinte ifomu, ukulingana noma ukusebenza komkhiqizo, iziteki ziphezulu emikhiqizweni enezintambo ezincane, okuhlanganisa izingxenye zamawashi, izibuko, omakhalekhukhwini, amakhamera edijithali, amabhodi esekethe aphrintiwe, imishini yezokwelapha enembile, kanye izingxenye ze-aerospace. Izingozi zibandakanya ukungaboni ngaso linye kwezingxenye ezihlanganisiwe, ubunzima ekuhlanganisweni, ama-burrs angase axege futhi angcolise izinhlelo zokuhlanzeka, kanye nokwehluleka kwe-fastener ensimini.

Izindlela zokuqeda inqwaba — Izindlela zokuqeda ubuningi njengokuwa, ukucisha ukushisa nokupholisha nge-electrochemical zingasebenza kahle ekususeni amabharmu athile ezingxenyeni ezincane. Ukuwisa, isibonelo, kungasetshenziswa ukususa amanye ama-burrs kodwa ngokuvamile akusebenzi ekugcineni kwemicu. Ngaphezu kwalokho, ukunakekelwa kuyadingeka ukuze kuvinjelwe ukuhlanganisa ama-burrs abe yizigodi zentambo, okungaphazamisa ukuhlanganisa.

Uma ama-burrs esemicu yangaphakathi, amasu okuqeda ubuningi kufanele akwazi ukufinyelela ekujuleni kwezakhiwo zangaphakathi.ingxenye yethusi

I-thermal deburring, isibonelo, isebenzisa amandla okushisa asondela ezinkulungwaneni ezimbalwa zama-degrees Fahrenheit ukuze ahlasele ama-burrs kuzo zonke izinhlangothi. Ngenxa yokuthi ukushisa akukwazi ukudlulisa kusuka ku-burr kuye kokubalulekile komzali, i-burr ishiswa kuphela kokubalulekile komzali. Kanjalo, ukususa okushisayo akuthinti noma yibuphi ubukhulu, ukuphela kwendawo, noma izici ezibonakalayo zengxenye yomzali.

I-electrochemical polishing iphinde isetshenziselwe ukukhipha futhi isebenza ngokulinganisa noma yiziphi iziqongo ezincane noma ama-burrs. Nakuba inqubo iphumelela, kusenokukhathazeka okuthile ngokuthi ingase ithinte imicu. Noma kunjalo, ngokuvamile, ukususwa kwezinto ezibonakalayo kuhambisana nokuma kwengxenye.

Naphezu kwezinkinga ezingase zibe khona, izindleko eziphansi zokuqeda ngobuningi zisakwenza kube inqubo ekhangayo kwezinye izitolo zemishini. Kodwa-ke, njengoba sekushiwo kakade, izitolo zemishini zikhetha ukugcina imisebenzi yesibili endlini uma kungenzeka.

Amabhulashi amancane okususa — Ezingxenyeni ezinentambo nezimbobo zomshini ezingaphansi kuka-0.125 in., amabhulashi amancane okwenza insimbi ayithuluzi elithengekayo lokususa amabhulashi amancane futhi enze ukupholisha kwangaphakathi. Amabhulashi amancane afika ngosayizi abahlukahlukene abancane (okubandakanya amakhithi), amakhonsathi nezinto zokwakha. Lawa mathuluzi afaneleka kakhulu ukubhekana nokubekezelelana okuqinile, ukuxutshwa konqenqema, ukukhipha imali nezinye izidingo zokuqeda.

“Izitolo zemishini ziza kithi zizofuna amabhulashi amancane ngoba azisafuni ukukhipha izingxenye zangaphandle futhi zifuna ukwenza lowo msebenzi ngaphakathi endlini,†kusho uJonathan Borden, oyimenenja yezokuthengisa kuzwelonke yeBrush Research Manufacturing. “Ngebhulashi elincane, akusadingeki bakhathazeke mayelana nezikhathi zokuhola nokuxhumana okwengeziwe ukuze bathumele izingxenye futhi bazibuyisele ngaphakathi.

Njengomphakeli womugqa ogcwele wezixazululo zokuqeda phezulu, i-BRM inikeza amabhulashi amancane okususa ngezinhlobo zemicu nezitayela zamathiphu. Ibhulashi elincane lobubanzi benkampani likala kuphela ku-0.014 in.

Amabhulashi amancane okususa angasetshenziswa ngesandla. Kodwa-ke, ngenxa yokuthi izintambo ze-brush stem zilungile kakhulu futhi zingagoba, umthuthukisi uncoma ukusebenzisa i-pin-vise. I-BRM inikezela ngephinikhodi eneziphetho ezimbili kumakhithi anamabhulashi afika kwangu-12 kukho kokubili idesimali (0.032 ukuya ku-0.189 in.) nosayizi bezimbobo zemethrikhi (1 mm ukuya ku-6.5 mm).

Amaphinikhodi nawo angasetshenziswa ukubamba amabhulashi amancane obubanzi ukuwavumela ukuthi ajikelezwe ngaphansi kwamandla ku-drill ephathwayo kanye nasemshinini we-CNC.

Amabhulashi amancane nawo angasetshenziswa entanjeni yangaphandle, ukususa ama-burrs amancane angase akheke ekuqaleni kwentambo. Lawa mabhula angabangela izinkinga futhi kufanele asuswe, ngoba noma iyiphi insimbi esusiwe ingase ibangele izimo ezibucayi nezingaba yingozi ezinhlelweni zezimboni ezidinga ukunemba nokuhlanzeka okukhethekile.

Ukuze uvimbele ukuchezuka kwesiqu socingo olusontekile lwebhulashi, okokusebenza kwe-CNC kungahlelwa ukuthi kusebenze ukucindezela okunembile kanye nesivinini sokujikeleza.

“Lezi zinhlobo zemisebenzi yokukhipha imali – ngisho namabhulashi amancane anobubanzi obuncane kakhulu – angenziwa ngokuzenzakalelayo,†kusho u-Borden. “Ungasebenzisa amathuluzi emishini ye-CNC usebenzisa iphinikhodi noma ngokwenza i-adaptha.

Kunezinhlobo eziningana zamabhulashi amancane atholakalayo namuhla angahlukanga nje ngosayizi, kodwa futhi nohlobo lwe-filament. Insimbi yekhabhoni, insimbi engagqwali, ithusi, inayiloni nenayiloni egcwele abrasive zivame ukusetshenziswa. Inayiloni egcwele i-abrasive ingase ibe ne-silicon carbide, i-aluminium oxide, noma i-diamond abrasive.

Ngokuka-Borden, inayiloni ehubhukayo isebenza kahle kakhulu ekususeni ama-burrs kanye neziqongo zentambo zokupholisha nama-engeli aseceleni kuzimbobo ze-aluminium ezithenjiwe. “Uma usika intambo enephuzu elilodwa ku-aluminium noma ingxenye ibilulwe kusetshenziswa ithuluzi ledayimane, kuzoba khona ama-engeli amaningi ‘fuzz’ kanye nama-angle ama-rough flank adinga ukupholishwa," echaza.

Amabhulashi ensimbi engagqwali amancane adumile ngokususa izinto ezinolaka ezifana nensimbi ecijile noma insimbi, ukususa ama-chips noma ukusula ama-burrs. Nakuba amabhulashi amancane enayiloni abrasive atholakala amancane njengo-0.032 in., ngenxa yemvelo ye-BRM yensimbi engagqwali manje inikeza osayizi abathathu bebhulashi abancane: 0.014, 0.018, kanye no-0.020 in.

Iphinde inikeze amabhulashi amancane asusayo anemicu enamathela idayimane ezintweni eziqinile, njengensimbi eqinile, i-ceramic, ingilazi, nama-alloys asemkhathini.

“Ukukhethwa komucu kuncike ekucacisweni kokuqedwa kwendawo, noma uma kunesidingo samandla okususa anamandla,†kusho u-Borden.

Wengeze ngokuthi ezinye izici ezisebenza kumabhulashi amancane asetshenziswa kuzinhlelo zokusebenza ezizenzakalelayo zifaka i-RPM yethuluzi lomshini, amanani okuphakelayo, kanye nokwenza kahle; ukugqoka-ukuphila.

Nakuba ukukhipha imicu emincane yangaphakathi neyangaphandle kungaba inselele, ukusebenzisa amathuluzi afaneleka kakhulu ohlelo olunikeziwe kungenza umsebenzi ube lula futhi kuqinisekise ukuthi wonke ama-burrs akhishwa njalo kuzo zonke izingxenye. Ukwengeza, ngokugwema ukukhishwa kwemisebenzi yesibili yokukhipha imali, izitolo zemishini zinganciphisa isikhathi sokushintsha kanye nentengo ingxenye ngayinye.UJeff Elliott ungumlobi wezobuchwepheshe osekelwe e-Torrance, e-Calif.
