Namuhla, kunezinhlobo eziningi zokubhoboza izinkuni kangangokuthi amakhasimende amaningi awazi ukuthi yiluphi uhlobo oludingayo.Lesi siqephu sizokunikeza imibono ethile.
Ama-Twist Drills: Ama-twist drill anamashanki ensimbi ayi-cylindrical kanye namathiphu.
Amasayizi amaningi ama-twist drill' blades makhulu njengama-shanks awo.Ipheya lemitshingo ye-helical (ngezinye izikhathi ebizwa ngokuthi ama-chip channels) ihambisana nezingxenye ezimbili kwezintathu zobude bayo, isongwe nxazonke njengemigqa esigxotsheni somgundi.
Intengo ye-twist drill ishibhile kunezinye izingcezu, kodwa imbobo yezingcezu ezenziweyo ayinembile.Isetshenziswa ezikhathini eziningi ngokubhola okuphansi okuyisicaba ukuze kuqinisekiswe ukunemba.Ngomzimba wensimbi, ama-twist drill awakwazi ukumelana nezinga lokushisa eliphezulu, ngakho-ke. awukwazi ukuyisebenzisa ngesivinini esijikelezayo.Ukusebenza kahle komshini wakho nakho kuzokhawulelwa.
Ama-Twist drill afaneleka kakhulu kwabazisebenzayo noma abasebenzisi abamathuluzi abo angekho emuva uma kuqhathaniswa.
Izingcezu ze-Spade.Lezi zingcezu zibukeka njengoba negama lazo lisho: i-shaft ngayinye yensimbi inqanyulwa nge-blade yefosholo.Ifosholo liyisicaba linephuzu elicijile phakathi.Leli phuzu lisebenza njengomhlahlandlela wokufaka phakathi imbobo futhi uqondise isiqondiso, kodwa iningi lokumba empeleni lenziwa i-honing cut edge ehlombe lefosholo.
Ngenxa yomklamo olula wama-spade bits, ayinalo ikhono elihle lokuphuma kwe-chip.Ngesikhathi esifanayo, ngenxa yomklamo wendiza onqenqemeni lokusika, ukusebenza kahle kokubhoboza kwe-spade bit kubi kakhulu.
Ngakho-ke, ngokunemba, ama-spade bits angcono kune-twist drill.Kodwa ukusebenza kahle kwayo kwemishini kufanele kube ukuvivinya okubi kunakho konke.
Ama-Twist drill afaneleka kakhulu kwabazisebenzayo abasebenzisa amathuluzi kagesi.
I-Brad Point Drills: Ukuze kuhlangatshezwane nezidingo zomshini wesivinini esikhulu, i-brad point drill bit yasungulwa.I-Brad point drill bit ihlanganisa izinzuzo ze-spade bit kanye ne-twist drill.Kukhona indawo yokubhoboza phakathi njengomhlahlandlela, futhi kunemiphetho emibili yokusika ezinhlangothini zombili ukuqinisekisa ububanzi bomgodi.Futhi izingcezu ze-brad point drill nazo zinemigodi ezungezayo ukukhulisa amandla okujula okujula.Idizayini ye-shank iphinde iqinisekise ukuthi ingasetshenziswa kangcono emishinini ye-CNC.
Futhi sithuthukise futhi sethule izinhlobo ezahlukene ze-brad point drill bits ukuze amakhasimende azisebenzise ezimeni ezahlukene.Izingcezu zokubhoboza i-ZY zifanele ukwenziwa kwemishini enesivinini esiphansi (1000-3000S/min).Ama-drill bits e-KJ-2 afanele ukwenziwa kwemishini yesivinini esiphakathi (2000-4000S/min).Izingxenye zokubhoboza ze-KJ-1 zifanele ukwenziwa kwemishini yesivinini esikhulu(3000-6000S/min).
I-Brad point drill bits iyisinqumo esingcono kakhulu kumakhasimende anemishini ye-CNC.
I-Countersink Drills.Izingcezu ezenziwe ngokukhethekile ziyathengiswa ezibhoboza izimbobo zokuhlola izikulufu zokhuni.Ama-Countersink drill anamaphrofayili ahambisana nokuma kwezikulufu: Izimbobo abazimbayo ziyancibilika kancane kancane kubude besikulufu, bese ziyakhula, zivumele amakhanda ezikulufu ukuthi abekwe (countersunk) okhunini.Ifanele ukusebenza kwezinkuni ze-CNC. umshini.
Amabhithi e-Forstner.Lezi zingcezu ezihlakaniphile zibhoboza izimbobo ezicishe zibe yisicaba.Kunokuba ibe nethiphu eliphansi elilandelwa ama-engeli anqunyiwe, ibhithi ye-Forstner iqondiswa unqenqema.Iziteshi zokubhoboza zisula imbobo yama-chips nothuli.Imbobo ewumphumela inephansi cishe eliyisicaba, lonakaliswe kuphela imbobo engu-1/32-intshi phakathi nendawo lapho i-starter spur yokubhoboza itholakala khona.
Amabhithi e-Forstner ayabiza kakhulu, futhi awadingeki emisebenzini eminingi.Kodwa-ke, abalulekile kwabanye, njengamahinji afakwayo okumele aphinde ahlehlwe embobeni eyindilinga enwebeka kancane esiteji somnyango.(Uma ubungasebenzisa i-spade ngenjongo efanayo, iphuzu layo cishe belizophumela ngaphesheya, lilimaze indawo.) Ifanele umshini wokwenza ukhuni we-CNC.
