I-HSS Single Flute Countersink Drill Bit
Umbukiso Womkhiqizo
Osinki bekhawunta banomkhawulo obukhali wokusika ekugcineni kwawo, kuyilapho ama-spiral flute ane-engeli ye-bevel, ngokuvamile eyaziwa ngokuthi i-rake angle, ekugcineni kwawo.Ukuze kuqinisekiswe ukugxilwa okuhle nokuqondiswa kwalokhu kuprakthiza, kuza neposi lomhlahlandlela elilingana kahle nembobo ekhona kakade endaweni yokusebenza ukuze kuqinisekiswe ukugxilwa okuhle nokuqondiswa.Ngenxa yalesi shaft esiyi-cylindrical kanye nekhanda elicibilikile elinembobo ye-oblique, ukubopha kwenziwa lula.Ithiphu ene-tapered ifakwe emaphethelweni e-beveled, efanelekile ngezinjongo zokusika.Ngembobo edlulayo, ama-chips ensimbi ayakwazi ukuphendukiswa futhi akhishwe phezulu ngenxa yembobo yokukhipha i-chip.Amandla e-Centrifugal angasiza kakhulu ekukhipheni amafayili ensimbi ebusweni bomsebenzi, ukuze angaklwebheli futhi athinte kabi ikhwalithi ye-workpiece.Kunezinhlobo ezimbili zokuthunyelwe komhlahlandlela, futhi izimbobo eziphikisayo zingenziwa ngesiqeshana esisodwa uma kunesidingo.
Ama-Countersink drill asetshenziselwa imisebenzi eyahlukene ehlanganisa ukubala kanye nokucubungula izimbobo ezibushelelezi.Idizayini yabo eyingqayizivele nesakhiwo kwenza kube lula kumsebenzisi ukuthi asebenze kahle futhi athuthukise ikhwalithi yomkhiqizo oqediwe.
