Uthotho: Kutheni ii-Drill Bits zingaphumeleli | Inqaku lesi-9
Amagama angundoqo: i-135° split point, i-split point drill bit, i-drill point angle, i-118° vs i-135° point angle, i-self-centing drill point, i-chisel edge, i-drill bit centering geometry
Inqaku elingaphambili kolu ngcelele lijonge ukuba kutheni ii-drill bits zihamba - i-short sideways skate ngexesha lokudibana, kwaye kutheni le nto iyingxaki yejometri kunokuba ibe yingxaki yezinto ezibonakalayo. Elo nqaku lilandelele unobangela ukuya kumphetho we-chisel: icandelo elisembindini wendawo yokumba ejijekileyo engasiki kakuhle, kodwa ikhupha kwaye isuse izinto endaweni yazo. Livale ngokuqaphela ukuba ukugaywa kwe-split point kunciphisa umda we-chisel kwaye kunciphisa ukuhamba, kwaye eli nqaku liza kugubungela isizathu ngokunzulu ngakumbi - kubandakanya nesizathu sokuba i-135° ibe yi-engile echazwe rhoqo ecaleni kwayo.
Eli nqaku lijonga ukuba i-split point grind itshintsha njani kwincam, kutheni i-engile ye-135° ihambelana nayo rhoqo, kunye noko abathengi bafanele bakujonge ngaphambi kokuba bacinge ukuba ilebheli kwiphepha le-spec ibonisa oko kugayiweyo kwintsimbi.
Ingxaki yeChisel Edge, iphinda ichazwe
Indawo yokubhola ejijekileyo yakhiwe ngemilebe emibini yokusika edibana kumphetho wetshisel odlula embindini. Umphetho wetshisel awuchebi izinto ngendlela imilebe ezenza ngayo - utyhala izinto phambi komphetho phantsi koxinzelelo. Yingakho indawo eqhelekileyo ifuna i-center punch okanye umngxuma wokulinganisa ukuqala ngokucocekileyo kwimisebenzi emininzi: okukhona umphetho wetshisel umde, kokukhona i-point ixhomekeke kwi-grinding symmetry yodwa ukuze ihlale iphakathi, kwaye kokukhona kuthatha i-axial thrust ukuze i-drill ilume.
Umphetho we-chisel awulosiphene kwi-standard twist drill — ngumphumo wendlela i-conical point elula egaywa ngayo. Kodwa ikwayeyona lever inkulu ekhoyo yokuphucula indlela i-drill eqala ngayo umngxuma, apho kanye i-split point geometry isebenza khona.
Oko iSplit Point Grind ikwenzayo ngokwenene
Ingongoma eqhekekileyo yongeza umsebenzi wesibini wokusila embindini wengongoma, inqumla inxalenye yomphetho wetshiseli ize ithathe indawo yayo ngemiphetho emibini emifutshane yokusika. Isiphumo esisebenzayo silula:
• Umphetho omfutshane wetshisel— idla ngokuncitshiswa ibe yincinci kunobude bayo kwindawo eqhelekileyo, nto leyo eshiya izinto ezimbalwa kakhulu ekufuneka zikhutshwe endaweni yokuba zichetywe.
• Imiphetho emibini eyongezelelweyo yokusika kufutshane nombindi— inqaku ngoku lisondela kwi-axis endaweni yokuthembela kwimilebe yangaphandle yodwa ukwenza wonke umsebenzi wokucheba.
• Ukutyhala okuphantsi kwe-axial— kufuneka amandla amancinci ukuze i-drill ilume, yiyo loo nto i-split point drills idla ngokuchazwa njenge-self-centering okanye i-self-starting.
• Ukuxhomekeka okunciphileyo kukulingana kokugaywa kuphela— nge-chisel edge emfutshane, i-asymmetries encinci phakathi kwemilebe emibini inomgama omncinci ekufuneka usebenze ngaphambi kokuba ingongoma idibane ngokufanelekileyo, nto leyo enciphisa ngokuthe ngqo utyekelo lokuhamba oluchazwe kwinqaku elidlulileyo.
Kutheni i-135°, ngokukodwa
I-engile yenqaku kunye nokusila okuqhekekileyo zizigqibo ezimbini ezahlukeneyo zoyilo ezihlala zichazwa kunye, kwaye kukho isizathu soomatshini soko kudityaniswa. Inqaku eliqhelekileyo lenjongo limalunga ne-118°. Inqaku le-135° lithe tyaba — lisondele kwi-perpendicular kwi-drill axis — kwaye oku kutshintsha indlela umthwalo wokusika osasazwa ngayo:
• Ukubandakanyeka okubanzi xa uqala ukudibana— i-engile yenqaku elithe tyaba isasaza umthwalo wokuqala wokusika kwicandelo elibanzi lemilebe endaweni yokuwugxininisa kwincam emxinwa, nto leyo enciphisa uxinzelelo oluphezulu ngexesha lokungena.
• Zilungele ngcono izinto eziqinileyo neziqinileyo— ukusasaza umthwalo kude nendawo emxinwa kubaluleke kakhulu kwiintsimbi ezingatshiyo, ii-alloys ezinamandla aphezulu, kunye nezinye izinto apho indawo eqhelekileyo igxininisa ubushushu kunye nokuguguleka encamini.
• Ukuqala ngokukhawuleza nangokucocekileyo ngaphandle kovavanyo— i-engile ethe tyaba edityaniswe ne-split point grind ivumela imiphetho emibini yokusika embindini ukuba ibandakanye izinto ngokukhawuleza, yiyo loo nto ii-split point drills ze-135° zisetyenziswa kakhulu ekubholeni okuphathekayo nokubanjwa ngesandla apho kungekho nto yokubamba i-bit embindini.
• Inzuzo edibeneyo ngokusila iindawo eziqhekekileyo— i-engile ethe tyaba inika imiphetho yokusika ephakathi ye-split point umphezulu ongaphezulu wokusebenza ngayo, ngoko ke isiphumo sokuzibeka kwindawo ephakathi se-split point grind sibonakala ngakumbi kwi-135° kunokuba besiya kuba njalo kwi-engile ethe tye.
Ngamafutshane: ukugaywa kweendawo ezihluliweyo kutshintsha okwenzekayo kumphetho we-chisel, kwaye i-engile ye-135° itshintsha indlela umthwalo ovela kuloo grind osasazwa ngayo kuyo yonke indawo. Akukho nanye kwezi zinto ithatha indawo yenye — ziyinxalenye ehambelanayo yenjongo yoyilo olufanayo.
Oku kuthetha ukuthini kumthengi
Ingcaciso ye-135° split point ichaza i-geometry ecetywayo, hayi isiphumo esiqinisekisiweyo. Ukuba loo njongo iyafezekiswa kuxhomekeke ngokupheleleyo ekuchanekeni kokusila, kwaye umsantsa phakathi kwezi zimbini ubonakala ngeendlela eziqikelelweyo:
• Ukuhamba kuyaqhubeka nangona ilebhile yeendawo ezihlukeneyo.Ukuba ukugaya okwesibini kumphetho we-chisel akunzulu, akulingani, okanye akusekho embindini, umda we-chisel ufinyezwa kuphela ngegama, kwaye i-drill isabonisa indlela yokuhamba, ukugaya okuqhekekileyo kwe-split point kujonge ukunciphisa.
• I-engile yenqaku engahambelaniyo kwibhetshi.Ibhetshi echazwe njenge-135° kodwa efikelela kwiidigri ezahlukeneyo kwicala ngalinye iya kusebenza ngokungaguqukiyo ukusuka kwelinye ukuya kwelinye — ezinye iziqwenga ziqala ngokucocekileyo, ezinye zisebenza kufutshane nenqaku eliqhelekileyo.
• Imiphetho yamanqaku ahlukeneyo angalinganiyo.Ukuba imiphetho emibini yokusika yesibini eyongezwe yi-split point grind ayilingani ngobude okanye nge-engile, inzuzo yokubeka phakathi iyawohloka ngendlela efanayo ne-standard lip grind engalinganiyo ebangela ukuhamba, kwaye isiphene singaba nzima ukuyibona ngaphandle kokujonga ngokusondeleyo incam.
Akukho nanye kwezi zinto ebonakala ngokufunda iphepha leenkcukacha okanye isihloko semveliso. Ibonakala kwindlela i-drill eqala ngayo umngxuma — nto leyo kanye i-point geometry ekufuneka ilawulwe ngayo kwasekuqaleni.
Indlela Abathengi Abanokuyiqinisekisa Ngayo
Iitsheki ezimbalwa zahlula inqaku lokwahlulahlula elingu-135° kwileyibhile esetyenziswa kwi-grind eqhelekileyo:
• Cela idatha yokuhlolwa kwe-engile yenqaku,hayi nje i-nominal angle kwiphepha le-spec. Ukufundwa kweprojektha okanye i-point-angle gauge kwi-sample batch kuya kubonisa ukuba i-angle ibanjwe rhoqo, kungekhona nje ukubangwa.
• Jonga ukuba ingaba i-drill isadinga ukubethelwa phakathi ukuze iqale kakuhle na.Inqaku lokwahlulahlula eliphunyezwe ngokufanelekileyo kufuneka liqale ngokungabaza okuncinci kakhulu kunenqaku eliqhelekileyo kwinto efanayo - ukuba alikwenzi oko, ukugaya okwesibini akwenzi umsebenzi walo.
• Hlola incam engaphantsi kokukhulisa ukuze ubone ukuba ayilingani.Imiphetho emibini yokusika yesibini embindini kufuneka ilingane ngokubonakalayo nangobukhulu; ukungalingani apha kukulingana nendawo yokwahlulahlula efana nokugawula imilebe ngendlela engalinganiyo.
Njengoko kunjalo ngolungelelwaniso lokusila oluxutyushwe kwinqaku elidlulileyo, injongo yoyilo emva kwenqaku lokwahlulahlula i-135° bubunjineli obuvakalayo — umbuzo kuye nawuphi na umthengi uhlala ungowokuba ngaba inkqubo yokusila engasemva kweleyibhile iyayizisa ngokwenene, rhoqo, ibhetshi emva kwenye.
Malunga nolu ngcelele
Kutheni i-Drill Bits Ingaphumeleli luluhlu lobuchwephesha olubhalwe liqela lethu lemveliso. Inqaku ngalinye ligxile kwinto enye ethile ekusebenzeni kwe-drill bit - ukusuka kwizinto eziluhlaza ukuya ekupakisheni.
