Ukushayela kuyindlela evame kakhulu yokucubungula ekwenziweni. Lapho uthenga izingcezwana ze-drill, ama-drill bits eza ngezinto ezahlukahlukene nemibala ehlukene. Ngakho-ke, imibala ehlukene yokushayela i-drill? Ngabe umbala unanoma yini ongayenza ngekhwalithi ye-drill bit? Yikuphi ukushayela umbala okungcono okungcono ukuthenga?
Okokuqala, kudingeka sikwenze kucace ukuthi ikhwalithi ye-drill kancane ayikwazi ukwahlulelwa ngombala wayo. Akunabo ubudlelwano obuqondile nobungenakugwenywa phakathi kombala nekhwalithi. Imibala ehlukene ye-drill bits ikakhulukazi ngenxa yamasu ahlukene wokucubungula. Vele, singenza ukwahlulela okunzima ngokusekelwe kumbala, kepha ama-bits aphansi aphansi aphansi azocubungula imibala yawo ukuze afinyelele ukubukeka okuphezulu kwekhwalithi ephezulu.
Ngakho-ke yini umehluko phakathi kokubiwa kwe-drill yemibala ehlukene?
Izinga eliphakeme eliphakeme ngokugcwele run-speed high speed high speed high speed but zivame ukutholakala zimhlophe. Vele, i-drill bit esongwe nayo ingaba mhlophe ngokugaya kahle umbuthano wangaphandle. Yini eyenza ukuthi ikhwalithi ephezulu akuyona nje impahla uqobo, kodwa futhi nokulawulwa kwekhwalithi ngesikhathi senqubo yokugaya. Kuqinile impela futhi ngeke kube khona ukushiswa endaweni yamathuluzi. Abamnyama bangama-nitride drill bits. Kuyindlela yamakhemikhali ebeka ithuluzi eliqediwe engxenyeni ye-ammonia kanye namanzi futhi yenza ukwelashwa kokulondolozwa kokushisa ku-540 ~ 560c ° ukwenza ngcono ukuqina kwethuluzi. Iningi le-Black Drill Bits okwamanje emakethe limnyama kuphela ngombala (ukuze limboze ukushiswa noma isikhumba esimnyama ebusweni bethuluzi), kepha umphumela wokusetshenziswa kwangempela awukathuthukiswa ngempumelelo.
Kunezinqubo ezi-3 zokukhiqiza izingcezwana zokumba. Ukugibela okumnyama kungukubi kakhulu. Abamhlophe banamaphethelo acacile futhi acwebile. Njengoba i-oxidation ephezulu yokushisa ingadingeki, ukwakheka okusanhlamvu kwensimbi ngeke kubhujiswe, kungasetshenziselwa ukumba izinsiza ezinobunzima obukhulu. Amabhithi we-Brow-brown Drill aqukethe i-cobalt, okuwumthetho ongashiwongo embonini ye-drill bit. Amadayimane aqukethe ama-cobalt amhlophe ekuqaleni, kepha kamuva ahlaselwa yi-Yellow-Brown (eyaziwa kakhulu ngokuthi i-Amber). Bangabanye abahle kakhulu ekusakazweni. I-M35 (CO 5%) nayo inombala wegolide obizwa nge-titanium-plated drill bit, ehlukaniswe ngokubambisana okuhlobisa kanye nenhlanganisela yezimboni. Ukuhlobisa okuhlobisa akukuhle, kubukeka kukuhle. Umphumela we-Electroitial Electroplating muhle kakhulu. Ubulukhuni bungafinyelela i-HRC78, ephakeme kunobulukhuni be-cobalting drill (HRC54 °).
Ungayikhetha kanjani i-Drill bit
Njengoba umbala akuyona inkambiso yokwahlulela ikhwalithi ye-drill bit, kanjani ukukhetha i-drill bit?
Ukusuka kokuhlangenwe nakho, ngokuvamile ukukhuluma, ukubhidliza okumhlophe ngokuvamile ngokuvamile kugcwele ama-bits e-speed speest speed all-speed speed ephezulu futhi kufanele ube nekhwalithi enhle kakhulu. IGolide linama-coatium nitride coatide futhi imvamisa kungaba okungcono kakhulu noma okubi kakhulu futhi kungakhohlisa abantu. Ikhwalithi yokuqhakaza nayo iyahlukahluka. Abanye basebenzisa insimbi esezingeni eliphansi lekhabhoni, okulula ukunxusa nokugqwala, ngakho-ke kudinga ukuba mnyama.
Kukhona uphawu lwentengiso nobubanzi bokubekezelela ukubekezelelana ku-shank of the drill bit, okuvame ukucacisa, futhi ikhwalithi ye-laser ne-electro-etching akufanele ibe yimbi kakhulu. Uma izinhlamvu ezibunjiwe zinemiphetho ye-convex, kukhombisa ukuthi i-drill bit ingekhwalithi engeyinhle, ngoba uhlaka lwe-convex lwezinhlamvu luzodala ukunembeza okucashile ukwehluleka ukufeza izidingo. Unqenqema lwegama luxhumeke kahle endaweni yesilinda sesilinda somsebenzi wesilinda, kanye ne-drill bit enonqenqemeni olucacile lwegama liyikhwalithi enhle. Kufanele ubheke i-drill bit ngonqenqema oluhle lokusika esiqeshini. Ukushayela okugcwele komhlaba wonke kunemiphetho emihle kakhulu yokusika futhi uhlangabezane nezidingo ze-helix surface, kuyilapho ukushayela kwekhwalithi ephezulu kunezindawo ezingezinhle zokucibishelwa kwecala.
