Ukuthenga isethi ye-drills kukugcina imali kwaye-ekubeni behlala beza kuhlobo oluthile lwebhokisi-kukunika ukugcinwa okulula kunye nokuchonga.Nangona kunjalo, ukungafani okubonakalayo okuncinci kwimilo kunye nezinto eziphathekayo kunokuba nefuthe elikhulu kwixabiso kunye nokusebenza.
Sidibanise isikhokelo esilula ekukhetheni isuntswana lokubhola kunye neengcebiso ezithile.Olona khetho luphezulu, i-IRWIN's 29-Piece Cobalt Steel Drill Bit Set, inokusingatha malunga nawo nawuphi na umsebenzi wokomba - ngakumbi iintsimbi eziqinileyo, apho amasuntswana okomba asemgangathweni angasilela.
Umsebenzi we-drill ulula, kwaye ngelixa uyilo olusisiseko lwe-groove aluzange lutshintshe amakhulu eminyaka, i-tip shape inokwahluka ukuze isebenze kwizinto ezahlukeneyo.
Ezona ntlobo zixhaphakileyo zii-twist drills okanye ii-rough drills, eziyindlela elungileyo yonke indawo.Utshintsho oluncinci yi-brad tip drill, eyenzelwe ukusetyenziswa ngomthi kwaye inencam emxinwa, incam ebukhali ethintela i-drill ukuba ingahambi (ekwabizwa ngokuba kukuhamba) .
Kanye ngaphezu kwe-intshi ububanzi, ukujija drills kuba engenzekiyo.I-drill ngokwayo yaba nzima kakhulu kwaye bulky.Inyathelo elilandelayo yi-drill umhlakulo, nto leyo sicaba kunye izikhonkwane macala omabini kunye nenqaku brad phakathi.Forstner kunye namasuntswana serrated nazo zisetyenziswa (zivelisa imingxuma ecocekileyo kunamasuntswana umhlakulo, kodwa ixabiso elingaphezulu kwe-hole yokubhobhoza ingqiqo ivalwe, i-hole drilling imvakalo yesiqhelo). ezi zisike isangqa sezinto.Eyona inkulu inokusika imingxunya i-intshi ezininzi ububanzi kwisangqa okanye iibhloko ze-cinder.
Uninzi lwee-drill bits zenziwe nge-high speed steel (HSS) .Akubizi, kulula ukuvelisa imiphetho yokusika ebukhali, kwaye ihlala ixesha elide.Inokuphuculwa ngeendlela ezimbini: ngokuguqula ukubunjwa kwentsimbi okanye ukuyigubungela ngezinye izinto.Iintsimbi ze-Cobalt kunye ne-chrome vanadium ziyimizekelo yangaphambili.Zinokuba nzima kakhulu kwaye zigugile, kodwa zibiza kakhulu.
Iingubo zokwaleka zifikeleleka ngakumbi ngenxa yokuba ziyimigangatho emincinci kumzimba we-HSS.I-tungsten carbide kunye ne-oxide emnyama zithandwa, njenge-titanium kunye ne-titanium nitride.I-diamond-coated drill bits yeglasi, i-ceramic kunye ne-masonry bits enkulu.
Iseti esisiseko yeshumi elinesibini okanye ngoko ke iibhithi ze-HSS kufuneka zibe semgangathweni kuyo nayiphi na ikiti yekhaya.Ukuba uyaphula enye, okanye ukuba uneemfuno ezithile ezingaphaya kobubanzi bayo, unokuhlala uthenge indawo eyahlukileyo.
Ngaphaya koko, sisithethe esidala malunga nokuba nezixhobo ezifanelekileyo zomsebenzi.Ukuzama ukwenza umthambo ongafanelekanga ukwenza umsebenzi kuyakhathaza kwaye kungonakalisa into oyenzayo.Azibizi, ngoko kusoloko kufanelekile ukutyala imali kuhlobo oluchanekileyo.
Ungathenga iseti ephantsi yoqheliso ngeerandi ezimbalwa, kwaye ngamanye amaxesha uzenze ngokwakho, nangona zihlala zibuthuntu ngokukhawuleza.Asinakucebisa amasuntswana okwakha akumgangatho ophantsi-kaninzi, awanamsebenzi.Iintlobo ngeentlobo zeeseti zomgangatho ophakamileyo woqheliso lwenjongo jikelele ziyafumaneka kwi-15 ukuya kwi-35 yeedola, kubandakanywa amasuntswana e-SDS amakhulu.
A. Kubantu abaninzi, mhlawumbi akunjalo. Ngokuqhelekileyo, babekwe kwii-degrees ze-118, ezilungele kakhulu iinkuni, izinto ezininzi ezidibeneyo, kunye neentsimbi ezithambileyo ezifana nobhedu okanye i-aluminium.
A. Kubuqhinga kancinci ukusebenzisa ngesandla, kodwa kukho iindidi ngeendidi zezinto zokusila okanye iziloli ezahlukeneyo ezikhoyo.Ii-Carbide drills kunye ne-titanium nitride (TiN) drills zifuna umloli osekwe ngedayimani.
Into esiyithandayo: Uluhlu olubanzi lweesayizi eziqhelekileyo kwikhasethi yokukhupha i-cassette efanelekileyo.Ukushisa kunye nokugqoka i-cobalt enganyangekiyo kwinkonzo eyandisiweyo.I-angle ye-135-degree inikeza i-metal cutting esebenzayo.I-Rubber boot ikhusela ityala.
Esikuthandayo: Ixabiso elikhulu, nje ukuba uyayiqonda imida ye-HSS bits.Ibonelela ngeedrili kunye nabaqhubi bemisebenzi emininzi ejikeleze ikhaya, igaraji kunye negadi.
Esikuthandayo: Kukho amaqhekeza amahlanu kuphela okugaya, kodwa anikezela ubungakanani bemingxuma engama-50. I-Titanium yokwambathisa ukwenzela ukuqina.Uyilo lokuzibamba, ukuchaneka okuphezulu.Iiflethi kwi-shank zithintela i-chuck ekutyibilikeni.
