Ithini i-engile ye-drill point?
Ichaza i-engile eyenziwe kwincam yokubhola, echaphazela ngokuthe ngqo indlela i-bit engena ngayo kwizinto. Ii-engile ezahlukeneyo zenzelwe ukuphucula ukusebenza kwazo zonke izixhobo ezahlukeneyo kunye neemeko zokubhola. Ezona-engile zimbini ziqhelekileyo nezithandwayo zokubhola kwimarike zii-degrees ezili-118 kunye ne-135.
I-engile ye-Drill Point ye-118°
Uninzi lwee-jobber drill bits ezisemgangathweni zenziwe nge-engile ye-118° point, ethathwa njengenjongo yokugrumba ngokubanzi. Le engile ibukhali ivumela i-drill ukuba ingene kwizinto ezithambileyo ngokukhawuleza nangokulula. Ngoko ke iya kufaneleka kwiinkuni, iplastiki, i-aluminium, kunye nentsimbi ethambileyo. Enye inzuzo yoyilo lwe-118 kukuba inokulolwa kwakhona ngokulula, abasebenzisi banokwandisa ubomi be-drill ngokugcinwa ngokufanelekileyo.
Nangona kunjalo, umda omnye kwi-118 unokuba "nokuhamba" okanye ukutyibilika xa ugqobhoza izinto eziqinileyo, ingakumbi ukuba awusebenzisi umngxuma wokuhlola kuqala. I-engile ebukhali iya kutyhala i-drill ngaphandle embindini xa ugqobhoza izinto eziqinileyo. Esi siphumo "sokuhamba" sinokunciphisa ukuchaneka kwaye singonakalisa umphezulu wezinto ukuba awunamngxuma wokuhlola kuqala.
Kwizicelo eziqinileyo, sicebisa ukuba ugqobhoze izinto okanye ugqobhoze umngxuma omncinci ngaphambi kokuba uzinzise umgqobho. Nangona le ngxaki ingekho, indawo yokugqobhoza eyi-118 iselukhetho oluthembekileyo nolungabizi kakhulu kwiimfuno zokugqobhoza zemihla ngemihla.
I-engile ye-Drill Point ye-135°
Ii-drill bits ezine-engile ye-135° point zihlala ziyilwe nge-split-point tip, enceda i-drill self-center kumphezulu wezinto. Olu yilo lunciphisa kakhulu amathuba "okuhamba" okanye ukutyibilika, ingakumbi xa usebenza kwiindawo eziqinileyo nezigudileyo. Ke ngoko, ii-drill ze-135° zinozinzo olungcono kunye nokuchaneka, nto leyo eyenza ukuba zifaneleke ngakumbi kwi-stainless steel, i-harded steel, kunye nezinye ii-alloys ezinzima apho ukuchaneka kubalulekile khona.
Iidrill ezili-135 nazo zinokuba nexesha elide lokusebenza kwezixhobo. Ngenxa yokuba i-engile eli-135 ibanzi, xa imiphetho yokusika ingena kwizinto, inokuba kancinci, idrill ayinaxinzelelo luninzi. Inceda ukuba ihlale ixesha elide xa isetyenziswa kwimisebenzi enzima. Oku kwenza iidrill ezili-135° zibe lukhetho olufanelekileyo kwizicelo zoshishino nezomsebenzi onzima apho kufuneka ukusebenza kakuhle nokuthembeka. Zinokugqobhoza imingxunya ecocekileyo kwaye zifuna amandla amancinci ukuze zihlale zilungelelene, ukusinceda siphucule ukhuseleko kunye nemveliso.
Nangona kunjalo, xa ugqobhoza izinto ezithambileyo ezifana nomthi okanye iplastiki, iidrill ze-135° zinokusika kancinci xa kuthelekiswa nedrill ye-118°. Kodwa ayiyongxaki inkulu kubasebenzisi bemizi-mveliso. Khumbula oku xa ufuna ukugqobhoza ngokukhawuleza kumsebenzi wokugqobhoza olula. Ngokubanzi, i-engile ye-135° ifanelekile kwimisebenzi enzima, inika ukuchaneka okuphezulu, ixesha elide lezixhobo, kunye nokusebenza okuphezulu kwiindawo ezifuna amandla.
Umahluko oPhambili ngokuKhawuleza
Ukuze senze izinto zibe lula, sishwankathele umahluko ophambili phakathi kwee-engile ze-drill point ze-118° kunye ne-135° kwitheyibhile engezantsi. Igxininisa ukusetyenziswa kwazo okuqhelekileyo, iingenelo, kunye nezinto eziqwalaselwayo, okwenza kube lula ukubona ukuba yeyiphi i-engile efanelekileyo kwiimfuno ezahlukeneyo zokubhola. Nokuba usebenza ngezinto ezithambileyo ezifana nomthi kunye ne-aluminium, okanye iintsimbi eziqinileyo ezifana nentsimbi engagqwaliyo, olu thelekiso lunokukunceda ukhawuleze uchonge i-drill bit efanelekileyo kulo msebenzi.
Zombini ii-drill bits ze-118° kunye ne-135° zinamandla azo. I-engile ye-118° isetyenziswa kakhulu kwaye ifanelekile kwimisebenzi yokubhola ngokubanzi, kwaye i-split point ye-135° isebenza ngcono kwizinto eziqinileyo xa ufuna ukuchaneka nokuzinza. Ukukhetha i-engile ye-point echanekileyo kuqinisekisa ukusebenza ngcono, ubomi besixhobo obude, kunye nokhuseleko oluphuculweyo.
