Ekucutshungulweni kwemishini, ukucutshungulwa kwembobo kwenza cishe ingxenye eyodwa kwezinhlanu zawo wonke umsebenzi wokwenza imishini, kanti ukumba kumelela cishe u-30% wengqikithi yokucubungula imbobo. Labo abasebenza kulayini wangaphambili wokubhola bajwayelene nezinsimbi zokubhoboza. Lapho uthenga ama-drill bits, ungabona ukuthi zenziwe ngezinto ezihlukene futhi ziza ngemibala ehlukahlukene. Ngakho-ke, uyini ngempela umehluko phakathi kwama-drill bits emibala ehlukene? Ingabe kukhona ukuhlobana phakathi kombala nekhwalithi yamabhithi okubhoboza? Yimuphi umbala we-drill bit oyikhethayo ongayithenga?
Ingabe bukhona ubuhlobo phakathi kombala we-drill bit kanye nekhwalithi?
Kubalulekile ukuqaphela ukuthi ikhwalithi ye-drill bits ayikwazi ukunqunywa kuphela umbala wabo. Nakuba kungekho ukuhlobana okuqondile nokungaguquguquki phakathi kombala nekhwalithi, ama-drill bits anemibala ehlukene ngokuvamile abonisa ukuhluka kobuchwepheshe bokucubungula. Ungenza ukuhlola okuqinile kwekhwalithi okusekelwe kumbala, kodwa khumbula ukuthi ama-drill bits ekhwalithi ephansi nawo angambozwa noma abe nombala ukuze anikeze ukubonakala kwezinketho zekhwalithi ephezulu.
Uyini umehluko phakathi kwama-drill bits anemibala ehlukene?
Izingcezu zokubhola zensimbi ezisezingeni eliphezulu, eziphansi ngokuphelele, ezinesivinini esikhulu ngokuvamile ziba mhlophe ngombala. Izingcezu zokubhola ezigoqiwe nazo zingenziwa zibe mhlophe ngokugaya kahle indawo engaphandle. Izinga eliphezulu lalezi zingcezu zokubhoboza alibangelwa nje kuphela impahla kodwa futhi nokulawulwa kwekhwalithi okuqinile ngesikhathi sokugaya, okuvimbela ukusha endaweni yamathuluzi.
Ama-black drill bits adlule inqubo ye-nitriding. Le ndlela yamakhemikhali ihlanganisa ukubeka ithuluzi eliqediwe enhlanganisela ye-ammonia nomhwamuko wamanzi, bese uyishisa ku-540-560 ° C ukuze uthuthukise ukuqina kwayo. Kodwa-ke, ama-drill bits amaningi amnyama atholakala emakethe anombala omnyama kuphela wokufihla ukusha noma ukungapheleli phezulu, ngaphandle kokwenza ngcono ukusebenza kwawo.
Kunezinqubo ezintathu eziyinhloko zokukhiqiza ama-drill bits:
1. Ukugingqika:Lokhu kubangela izinsimbi zokubhola ezimnyama futhi kuthathwa njengekhwalithi ephansi kakhulu.
2. Ukuhlanza Nokugaya Umphetho:Le nqubo ikhiqiza izingcezu zokubhoboza ezimhlophe, ezingatholi i-oxidation yezinga eliphezulu lokushisa, egcina isakhiwo sezinhlamvu zensimbi. Lezi zingcezu zilungele ukubhola izingcezu zokusebenza ezinobunzima obuthe ukukhuphuka.
3. Ukuzivocavoca Okuqukethe I-Cobalt:Okubizwa ngokuthi ama-drill bits aphuzi ngokunsundu embonini, lawa ekuqaleni amhlophe futhi athola umbala ophuzi ngokunsundu (okuvame ukubizwa nge-amber) phakathi nezinqubo zokugaya kanye ne-atomizing. Njengamanje ayikhwalithi ephezulu kakhulu etholakala emakethe. Izinsimbi zokubhoboza i-M35, eziqukethe i-cobalt engu-5%, zingaba nombala osagolide.
Ukwengeza, kukhona imishini yokubhoboza i-titanium, engahlukaniswa ngezinhlobo ezimbili: i-plating yokuhlobisa kanye ne-industrial plating. Ukuhlobisa okuhlobisa akufezi injongo engokoqobo ngaphandle kobuhle, kuyilapho ukucwenga kwezimboni kunikeza izinzuzo ezibalulekile, ukuziqhayisa ngobulukhuni be-HRC 78, obukhulu kunobo bokuprakthiza okuqukethe i-cobalt, ngokuvamile okukalwa ku-HRC 54.
Indlela yokukhetha i-drill bit
Njengoba umbala ungewona umbandela wokwahlulela ikhwalithi ye-drill bit, singayikhetha kanjani i-drill bit?
Ngokusekelwe kokuhlangenwe nakho kwami, ama-drill bits afika ngemibala ehlukene evame ukukhombisa ikhwalithi yawo. Ngokuvamile, izinsimbi zokubhola ezimhlophe zenziwe ngensimbi enesivinini esiphezulu esiphansi ngokuphelele futhi ngokuvamile ziyikhwalithi engcono kakhulu. Izingcezu zokumba igolide ngokuvamile ziyi-titanium nitride-plated futhi zingahluka ngekhwalithi-zingase zibe zinhle kakhulu noma zibe nebanga eliphansi. Izinga le-black drill bits ngokuvamile alihambisani; ezinye zenziwe ngensimbi yamathuluzi ekhabhoni ephansi, ekwazi ukugqwala kalula futhi igqwale, okwenza kudingeke ukuthi kuphele ubumnyama.
Lapho uthenga i-drill bit, kufanele uhlole uphawu lokuhweba kanye ne-diameter tolerance mark kusibambo sokubhoboza. Uma uphawu lucacile futhi luchazwe kahle, luphakamisa ukuthi ikhwalithi inokwethenjelwa, kungakhathaliseki ukuthi yenziwa kusetshenziswa amasu e-laser noma okugqwala kagesi. Ngokuphambene, uma uphawu lubunjiwe futhi imiphetho iphakanyisiwe noma iqhumile, i-drill bit ingase ibe nekhwalithi embi. I-bit yekhwalithi enhle izoba nokumaka okucacile okuxhuma kahle endaweni eyi-cylindrical yesibambo.
Ukwengeza, hlola umkhawulo wokusika wethiphu yokubhoboza. Ibhithi lokubhoboza elisezingeni eliphezulu, eligcwele phansi lizoba nensingo ecijile kanye nendawo ezungezayo eyakhiwe kahle, kanti ingxenye yekhwalithi ephansi izobonisa ubuciko obumpofu, ikakhulukazi endaweni engemuva.
Ukunemba kokumba
Ngemva kokukhetha i-drill bit, ake sibheke ukunemba kokumba.
Ukunemba kwembobo ebhoboliwe kuthonywa izici ezimbalwa, okuhlanganisa ubukhulu bembobo, ukunemba kwendawo, ukuhlangana, ukuzungeza, ukuhwaqazeka kwendawo, kanye nokuba khona kwama-burrs.
Izinto ezilandelayo zingathinta ukunemba kwembobo ecutshunguliwe ngesikhathi sokumba:
1. Ukunemba kokuphoqa kanye nezimo zokusika zebhithi yokubhoboza, ezihlanganisa isibambi samathuluzi, isivinini sokusika, izinga lokuphakelayo, kanye nohlobo loketshezi lokusika olusetshenzisiwe.
2. Usayizi nokuma kwe-drill bit, okuhlanganisa ubude bayo, i-blade design, kanye nokuma kwe-drill core.
3. Izici ze-workpiece, njengokuma kwezinhlangothi zembobo, i-geometry yembobo iyonke, ukujiya, kanye nendlelamachining prototypeiboshiwe ngesikhathi sokumba.
1. Ukunwetshwa kwemigodi
Ukunwetshwa kwembobo kwenzeka ngenxa yokunyakaza kwe-drill bit ngesikhathi sokusebenza. Ukushwibeka komphathi wamathuluzi kuthinta kakhulu kokubili ububanzi bembobo nokunemba kokuma kwayo. Ngakho-ke, uma umnikazi wamathuluzi ebonisa izimpawu zokuguga okukhulu, kufanele ashintshwe ngokushesha afakwe entsha.
Lapho ubhoboza izimbobo ezincane, ukulinganisa nokulungisa ukujiya kungaba inselele. Ngenxa yalesi sizathu, kuhle ukusebenzisa umshini wokubhoboza we-shank one-diameter encane ye-blade egcina i-coaxiality enhle phakathi kwe-blade ne-shank.
Uma usebenzisa i-re-ground drill bit, ukwehla kokunemba kwembobo kuvame ukuba ngenxa yomumo ongalingani wengxenye engemuva yebhithi. Ukuze unciphise ngempumelelo ukusika imbobo nokwandiswa, kubalulekile ukulawula umehluko wokuphakama kwe-blade.
2. Imbobo eyindilinga
Ukudlidliza kwebhithi yokubhoboza kungabangela imbobo ebhoboziwe ukuthi ithathe umumo we-polygonal, kube nemigqa yokudubula evela ezindongeni. Izinhlobo ezijwayelekile zezimbobo ezinama-polygonal ngokuvamile zingunxantathu noma i-pentagonal. Imbobo engunxantathu yakha lapho i-drill bit inezikhungo ezimbili zokuzungeza ngesikhathi sokumba, ezivezela imvamisa yokujikeleza okungu-600 ngomzuzu. Lokhu kudlidliza kubangelwa ikakhulukazi ukumelana nokusika okungenakulinganisela. Njengoba i-drill bit iqeda ukuzungezisa ngakunye, ukuzungeza kwembobo kuba sengozini, okuholela ekuphikiseni okungenakulinganisela phakathi nokusikeka okulandelayo. LokhuInqubo yokuguqula i-CNCiyaphinda, kodwa isigaba sokudlidliza sishintsha kancane ngokujika ngakunye, okuholela emigqeni yokudubula odongeni lwembobo.
Uma ukujula kokumba kufinyelele ezingeni elithile, ukungqubuzana phakathi konqenqema lwebhithi yokubhoboza nodonga lwembobo luyakhula. Lokhu kungqubuzana okuphezulu kudambisa ukudlidliza, kubangele ukuthi isibhamu sinyamalale futhi sithuthukise ukuzungeza kwembobo. Imbobo ewumphumela ngokuvamile ithatha umumo wefaneli uma ibukwa esigabeni esiphambanayo. Ngokufanayo, izimbobo ze-pentagonal kanye ne-heptagonal zingase zakheke ngesikhathi sokusika.
Ukuze unciphise le nkinga, kubalulekile ukulawula izici ezihlukahlukene, njengokudlidliza kwe-chuck, umehluko wobude obunqunyiwe, i-asymmetry yobuso bangemuva, kanye nokuma kwama-blades. Ukwengeza, kufanele kusetshenziswe izinyathelo zokuthuthukisa ukuqina kwe-drill bit, kukhushulwe izinga lokudla ngakunye, kuncishiswe i-engeli yangemuva, futhi kugaywe kahle unqenqema lweshizolo.
3. Ukubhoboza ezindaweni ezithambekile nezigobile
Lapho indawo yokusika noma yokubhoboza ye-drill bit ithambekele, igobile, noma imise okwesinyathelo, ukunemba kokuma kwayo kuncipha. Lokhu kwenzeka ngoba, ezimweni ezinjalo, i-drill bit isika ngokuyinhloko ohlangothini olulodwa, okwenza ibe mfushane impilo yayo yamathuluzi.
Ukuthuthukisa ukunemba kokumisa, izinyathelo ezilandelayo zingathathwa:
-Bomba imbobo ephakathi kuqala;
-Sebenzisa i-end Mill ukuze ugaye isihlalo somgodi;
-Khetha i-drill bit ngokusebenza okuhle kokusika nokuqina okuhle;
-Yehlisa isivinini sokuphakelayo.
4. Ukwelashwa kwe-Burr
Ngesikhathi sokumba, ama-burrs avame ukwakheka kukho kokubili ukungena nokuphuma kwembobo, ikakhulukazi uma kusebenza ngezinto eziqinile namapuleti amancane. Lokhu kwenzeka ngoba, njengoba i-drill bit isondela endaweni yokubhoboza impahla, i-material iba nokuwohloka kwepulasitiki.
Kulo mzuzu, ingxenye engunxantathu okuhloswe ngayo ukusika unqenqema lwe-drill bit ikhubazekile futhi igobe ngaphandle ngenxa yamandla okusika axial. Lokhu kuguqulwa kubhebhethekiswa nakakhulu i-chamfer enqenqemeni yangaphandle ye-drill bit kanye nomphetho we-workpiece, okuholela ekwakhekeni kwama-curls noma ama-burrs.
