Ngokwezindlela ezihlukene zokucubungula, ama-twist drill okwamanje asemakethe ahlukaniswe cishe abe yizinhlobo ezilandelayo:
1. I-Rolled twist drill
Ngemuva kokuba insimbi yesivinini esikhulu ishise futhi ishiswe ngokubomvu, ukuma kwe-twist drill kukhishwa ngokushesha ngesikhathi esisodwa.Ngemva kwalokho, i-twist drill idinga kuphela ukuphathwa ngokushisa futhi ifakwe phezulu ukuze ilole ikhanda ngaphambi kokuthi isetshenziswe.
Inzuzo enkulu yenqubo ukusebenza kahle kokukhiqiza kanye nokusetshenziswa okugcwele kwezinto ezingavuthiwe;isakhiwo sangaphakathi somzimba wokugaya ocutshungulwayo sinokuqhubeka kwe-fiber, futhi okusanhlamvu kucwengisiswe, ama-carbides asakazwa ngokulinganayo, futhi ubulukhuni obomvu buphezulu.
Kodwa-ke, inqubo yokugoqa nayo ineziphambeko ezisobala, okungukuthi, umzimba wokubhoboza kulula kakhulu ukuqhekeka, noma kuzoba nokuqhekeka okungelula ukukubona, futhi ngenxa yokuthi kwakhiwa ngesikhathi esisodwa, ukunemba okuphelele kwe-drill. ngeke ibe phezulu ikakhulukazi.
Okwamanje, twistubhoboza namanjengokuvamile zisebenzisa le ndlela yokucubungula, ngakho-ke ama-rolled twist drill emakethe yohwebo lwangaphandle ikakhulukazi asezingeni eliphakathi neliphansi.
2. Groove ukugaya emuvatwist drill
Ngenxa yesimo sokuthi ukuginqika kulula ukwakha imifantu, ngaphezu kuka-98% wemifantu ekuzibhobhozeni kokusonta kwe-rolling kwenzeka ezimpambanweni zezwe kanye nemisele.
Kodwa-ke, okokuqala ukukhipha i-groove enqenqemeni ye-drill kumshini wokugaya, bese ugaya kahle indilinga yangaphandle ethuluzini lomshini, kuyixazulula ngokuphelele le nkinga.
Futhi ngenqubo yokugaya kahle umbuthano wangaphandle, hhayi nje kuphela ukuthi inkinga yokuqhekeka ingaxazululwa, kodwa futhi nokunemba kwemishini ye-drill bit kanye nokunemba kwe-radial circular runout kungathuthukiswa.
3. Iphansi ngokupheleletwist drill
Njengamanje, ubuchwepheshe bokugaya obujwayelekile kakhulu emhlabeni wonke, ama-twist drills wonke enziwe ngamasondo okugaya kusukela ekusikeni kwezinto ezibonakalayo, kuya ekugayeni kwe-groove, ukugaya emuva, ukusika onqenqemeni kanye nokusika i-engeli.
I-twist drill ephansi ngokuphelele futhi epholishiwe inokubukeka okuhle nokushelelayo, futhi izilinganiso eziyinhloko ezifana nokuphuma kwe-radial, ukujiya komgogodla, nokwenyuswa kogqinsi komgogodla kulawulwe kahle kakhulu, futhi ukunemba kuphezulu kakhulu.
Kodwa-ke, empeleni, inqobo nje uma inqubo yokugoqa kanye nezinga lokwelashwa kokushisa likhona, ukugoqa kusengcono ngokombono wokuqina.
