I-TWIST DRILL
Imininingwane Eyisisekelo
Ukukhethwa kwempahla yokubhola okusontekile kuncike kakhulu kuhlelo lokusebenza kanye nohlobo lwezinto ezibonakalayo, ngokuvamile ezihlukaniswe ngensimbi enesivinini esikhulu, insimbi ye-carbon nensimbi ye-tungsten.I-HSS ilungele izinsimbi nezinkuni eziqinile, kuyilapho i-carbon steel ingcono ezintweni ezizacile njengezinkuni ezithambile nensimbi engenalutho.Ama-Tungsten steel twist drill angasetshenziselwa ukubhoboza izimbobo ezijulile nezinde futhi kubholwe insimbi ye-alloy yekhwalithi ephezulu kanye nobumba ngobulukhuni obukhulu.
Naka amaphuzu alandelayo uma usebenzisa ama-twist drill:
1. Khetha i-twist drill efanele: khetha i-twist drill efanele ngokuya ngezinto ezihlukene kanye namadiamitha okubhola.
2. Ukwelashwa ngaphambi kokumba: lungiselela isifanekiso esifanele sokumba, futhi wenze ukulinganisa, ukulinganisa kanye nokumaka njengoba kudingeka.
3. Sebenzisa uketshezi olufanele lokusika: khetha uketshezi olufanele lokusika ngokusho kwezinto zokumba ukuze uqinisekise ukuthi i-drill bit isebenza esimweni esihle kakhulu futhi uvimbele ukuguga ngokweqile.
4. Qinisa ukuvikela ukuphepha: Gqoka okokuvikela okufanele njengamagilavu okuvikela kanye nezibuko lapho ubhoboza ukuze ugweme ukulimala kwamehlo nezandla.Ngesikhathi esifanayo, kuyadingeka futhi ukunaka izici zokuphepha ezifana nokunikezwa kwamandla kanye nezintambo zomshini kagesi.
