Iyini i-engeli yephuzu lokubhoboza?
Ichaza i-engeli eyakhiwe echosheni lokubhoboza, ethinta ngqo indlela i-bit engena ngayo ezintweni. Ama-engeli ahlukene aklanyelwe ukwenza ngcono ukusebenza kuzo zonke izinto ezahlukene kanye nezimo zokubhoboza. Ama-engeli amabili avamile futhi adumile okubhoboza emakethe angama-degree angu-118 kanye no-135.
I-engela ye-Drill Point engu-118°
Ama-drill bits amaningi ajwayelekile e-jobber enziwe nge-engeli engu-118°, ecatshangelwa ngenhloso yokubhoboza evamile. Le engeli ebukhali ivumela i-drill ukuthi ingene ezintweni ezithambile ngokushesha nangokulula. Ngakho-ke izofaneleka ngokhuni, ipulasitiki, i-aluminium, kanye nensimbi ethambile. Enye inzuzo yomklamo we-118 ukuthi ingalolwa kabusha kalula, abasebenzisi bangandisa impilo ye-drill ngokunakekelwa okufanele.
Kodwa-ke, umkhawulo owodwa we-118 cishe “ukuhamba” noma ukushelela lapho ubhoboza izinto eziqinile, ikakhulukazi uma ungasebenzisi imbobo yokuhlola kuqala. I-engeli ebukhali izoba lula ukuyisunduza ngaphandle kwesikhungo lapho ubhoboza ezintweni eziqinile. Lo mphumela “wokuhamba” unganciphisa ukunemba futhi ungalimaza ubuso bezinto uma ungenayo imbobo yokuhlola kuqala.
Uma ufuna ukusebenzisa izinto eziqinile, sincoma ukuthi ubhoboze phakathi nendawo noma ubhoboze imbobo encane kusengaphambili ukuze uqinise ibhobo. Naphezu kwalokhu kuphazamiseka, indawo yokubhoboza engu-118 iseyindlela ethembekile nengabizi kakhulu yezidingo zansuku zonke zokubhoboza.
I-engela ye-Drill Point engu-135°
Izingcezu zokubhoboza ezine-engeli engu-135° zivame ukuklanywa nge-split-point tip, okusiza ukuthi i-drill izibeke phakathi nendawo. Lo mklamo unciphisa kakhulu amathuba "okuhamba" noma okushelelayo, ikakhulukazi lapho usebenza ezindaweni eziqinile nezibushelelezi. Ngakho-ke, ama-drill angu-135° anokuqina nokunemba okungcono, okwenza afaneleke kakhulu ensimbi engagqwali, insimbi eqinile, kanye nezinye izinhlobo eziqinile lapho ukunemba kubalulekile khona.
Ama-drill angu-135 nawo angaba nesikhathi eside sokusebenza kwamathuluzi. Ngenxa yokuthi i-engeli engu-135 ibanzi, lapho imiphetho yokusika ingena ezintweni, ingaba kancane, i-drill inengcindezi encane. Isiza ukuthi ihlale isikhathi eside uma isetshenziswa emisebenzini enzima. Lokhu kwenza ama-drill angu-135° abe ukukhetha okuhle ezisetshenziswayo zezimboni nezisebenzi ezisindayo lapho kudingeka khona ukusebenza kahle nokuthembeka. Angabhoboza imigodi ehlanzekile futhi adinga amandla amancane ukuze ahlale eqondile, ukuze asisize sithuthukise ukuphepha nokukhiqiza.
Kodwa-ke, uma ubhoboza ezintweni ezithambile njengokhuni noma ipulasitiki, ukubhoboza okungu-135° kungasika kancane uma kuqhathaniswa nokubhoboza okungu-118°. Kodwa akuyona inkinga enkulu kubasebenzisi bezimboni. Khumbula lokhu uma udinga ukubhoboza okusheshayo emsebenzini wokubhoboza olula. Sekukonke, i-engeli engu-135° ilungele imisebenzi enzima, inikeza ukunemba okuphezulu, isikhathi eside samathuluzi, kanye nokusebenza okuhle kakhulu ezindaweni ezidinga amandla amaningi.
Umehluko Oyinhloko Ngokushesha
Ukuze senze izinto zibe lula, sifingqe umehluko obalulekile phakathi kwama-engeli okubhoboza angu-118° no-135° etafuleni elingezansi. Kugqamisa ukusetshenziswa kwawo okuvamile, izinzuzo, kanye nokucatshangelwa, okwenza kube lula ukubona ukuthi iyiphi i-engeli efanelekela kangcono izidingo ezahlukene zokubhoboza. Kungakhathaliseki ukuthi usebenza ngezinto ezithambile njengokhuni ne-aluminium, noma izinsimbi eziqinile njengensimbi engagqwali, lokhu kuqhathanisa kungakusiza ukuthi usheshe ukhombe i-drill bit efanele lomsebenzi.
Zombili izingcezu zokubhoboza ezingu-118° kanye no-135° zinamandla azo. I-engeli engu-118° isetshenziswa kakhulu futhi ilungele imisebenzi evamile yokubhoboza, kanti iphuzu lokuhlukaniswa elingu-135° lisebenza kangcono ezintweni eziqinile uma udinga ukunemba nokuzinza. Ukukhetha i-engeli yephuzu elifanele kuqinisekisa ukusebenza kahle okungcono, isikhathi eside sokuphila kwamathuluzi, kanye nokuphepha okuthuthukisiwe.
