I-HSS eyodwa ye-Flue CounterSink Drill kancane
Umkhiqizo Umbukiso
Ama-counter sink anomphetho obukhali wokusika ekugcineni kokuphela kwawo, kuyilapho imibhoxo ye-Spiral ibe ne-angle ye-bevel, evame ukwaziwa ngokuthi i-rake angle, empini yayo. Ukuze uqinisekise ukugxila okuhle nokuholwa kwalolu shayela, kuza neposi eliyisiqondisi elifanelana nomgodi okhona osevele usesimweni sokusebenza ukuze uqinisekise ukugxila nokuqondisa okuhle. Njengomphumela wale cylindrical shaft kanye nekhanda le-tapered ngomgodi oblique, ukubopha kwenziwa lula. Ithiphu ye-tapered ifakwe onqenqemeni olubunjiwe, olufanele izinhloso zokusika. Ngokusebenzisa umgodi, ama-iron chips ayakwazi ukujikeleza futhi akhishwe phezulu ngenxa yomgodi we-chip ukukhipha umgodi. Ama-centrifugal amabutho angasiza kakhulu ekukhupheni imidwebo yensimbi ebusweni bomsebenzi, ukuze bangakwazi ukuklaba ingaphezulu futhi bathinte kabi ikhwalithi yesisebenzi somsebenzi. Kunezinhlobo ezimbili zokuthumela umhlahlandlela, kanye nezimbobo ze-couresink nazo zingenziwa esiqeshini esisodwa uma kunesidingo.
I-CounterSink Drill isetshenziselwa imisebenzi ehlukahlukene kufaka phakathi i-Countersinking kanye nokucubungula izimbobo ezibushelelezi. Idizayini yabo eyingqayizivele nesakhiwo yenza kube lula ukuthi umsebenzisi asebenze kahle futhi athuthukise ikhwalithi yomkhiqizo ophelile.
