Uchungechunge: Kungani Ama-Drill Bits Ehluleka | Isihloko 9
Amagama angukhiye: iphuzu elihlukanisiwe elingu-135°, i-drill bit yephuzu elihlukanisiwe, i-drill point angle, i-118° vs i-135° point angle, i-drill point ezigxilisa yona, umphetho we-chisel, i-drill bit centering geometry
Isihloko sangaphambilini kulolu chungechunge sibheke ukuthi kungani izingcezu zokubhoboza zihamba - i-skate emfushane eceleni ngesikhathi sokuxhumana, nokuthi kungani kuyinkinga yejiyometri kunokuba kube yinkinga yezinto ezibonakalayo. Leso sihloko silandele imbangela emuva onqenqemeni lwe-chisel: ingxenye ephakathi nendawo yokubhoboza ejwayelekile engasiki kahle, kodwa ekhipha futhi isuse izinto esikhundleni salokho. Sivale ngokuqaphela ukuthi ukugaya indawo ehlukanisiwe kunciphisa onqenqemeni lwe-chisel futhi kunciphisa ukuhamba, nokuthi lesi sihloko sizochaza ukuthi kungani ngokujulile - kufaka phakathi ukuthi kungani i-135° iyi-engeli evame ukucaciswa eceleni kwayo.
Lesi sihloko sibheka ukuthi i-split point grind ishintsha kanjani ngempela esicongweni, ukuthi kungani i-engeli engu-135° ihambisana nayo njalo, nokuthi yini abathengi okufanele bayihlole ngaphambi kokuthi bacabange ukuthi ilebula ephepheni le-spec libonisa lokho okugayiwe ngempela ensimbini.
Inkinga Yomphetho We-Chisel, Iphinde Yashiwo
Indawo yokubhoboza ejwayelekile yakhiwe ngezindebe ezimbili ezisikiwe ezihlangana onqenqemeni lwesitshezi oluhamba phakathi nendawo. Unqenqema lwesitshezi alugundi izinto ngendlela izindebe ezenza ngayo - lusunduza izinto ngaphambi kwephuzu ngaphansi kokucindezelwa. Yingakho iphuzu elijwayelekile lidinga ukubhoboza okuphakathi noma umgodi wokuhlola ukuze liqale kahle emisebenzini eminingi: uma unqenqema lwesitshezi lude, iphuzu lithembele kakhulu ekulinganiseni kokugaya kuphela ukuze lihlale liphakathi nendawo, futhi kuthatha ukujikijela okune-axial ukuze ibhoboze ilume.
Unqenqema lwesisele aluyona iphutha ku-drill ejwayelekile yokujika — luwumphumela wendlela iphuzu eliyindilinga eligaywa ngayo. Kodwa futhi luyi-lever enkulu kunazo zonke etholakalayo yokuthuthukisa indlela i-drill eqala ngayo umgodi, okuyilapho i-geometry yamaphuzu ahlukanisiwe isebenza khona.
Lokho Okwenziwa Yi-Split Point Grind Empeleni
Iphuzu elihlukanisiwe lengeza umsebenzi wesibili wokugaya maphakathi nephuzu, lisika ingxenye yomphetho we-chisel bese liyishintsha ngeminye imiphetho emibili yokusika emifushane. Umphumela osebenzayo ulula:
• Umphetho omfushane we-chisel— ngokuvamile incishiswa ibe yingxenyana yobude bayo endaweni ejwayelekile, okushiya izinto ezimbalwa kakhulu okumele zikhishwe esikhundleni sokugundwa.
• Imiphetho emibili eyengeziwe yokusika eduze nendawo ephakathi— iphuzu manje selisondela eduze kwe-axis esikhundleni sokuthembela ezindebeni zangaphandle zodwa ukuze zenze wonke umsebenzi wokugunda.
• Ukucindezela kwe-axial okuphansi— kudingeka amandla amancane ukuze i-drill ilume, yingakho i-split point drills ivame ukuchazwa njengokuzigxilisa noma ukuziqala.
• Ukwencika okuncishisiwe ekulinganisweni kokugaya kuphela— ngomphetho omfushane we-chisel, ukungalingani okuncane phakathi kwezindebe ezimbili kunebanga elincane okufanele lisebenze ngaphambi kokuba iphuzu lihlangane kahle, okunciphisa ngqo ukuthambekela kokuhamba okukhulunywe ngakho esihlokweni esandulele.
Kungani 135°, Ngokuqondile
I-engeli yephuzu kanye nokugaya iphuzu elihlukanisiwe kuyizinketho ezimbili ezihlukene zokuklama ezivame ukucaciswa ndawonye, futhi kunesizathu somshini salokho kubhanqa. Iphuzu elijwayelekile lenjongo ejwayelekile lihlala cishe ku-118°. Iphuzu elingu-135° liyisicaba — lisondele kakhulu ekuqondeni kwe-drill axis — futhi lokhu kushintsha indlela umthwalo wokusika osakazwa ngayo:
• Ukuzibandakanya okubanzi ekuxhumaneni kokuqala— i-engeli eqondile isakaza umthwalo wokuqala wokusika engxenyeni ebanzi yezindebe kunokuba iwugxilise esicongweni esincane, okwehlisa ukucindezeleka okuphezulu ngesikhathi sokungena.
• Kulungele kangcono izinto eziqinile neziqinile— ukusabalalisa umthwalo kude nendawo encane kubaluleke kakhulu ezinsimbini ezingagqwali, ama-alloy anamandla aphezulu, nezinye izinto lapho indawo ejwayelekile igxila khona ukushisa nokuguguleka esicongweni.
• Ukuqala okusheshayo nokuhlanzekile ngaphandle kokuhlolwa— i-engeli eyisicaba ehlanganiswe nokugaya okuhlukaniswe ngamaphoyinti kuvumela imiphetho emibili yokusika ephakathi ukuthi ibambe izinto ngokushesha, yingakho ukubhola okuhlukaniswe ngamaphoyinti angu-135° kuvame ukusetshenziswa ekubholeni okuphathekayo nokubanjwa ngesandla lapho kungekho khona into yokubamba i-bit phakathi nendawo.
• Inzuzo ehlanganisiwe ngokugaya amaphuzu ahlukene— i-engeli eyisicaba inikeza imiphetho yokusika ephakathi nendawo ehlukanisiwe indawo engaphezulu yokusebenza ngayo, ngakho-ke umphumela wokuzigxilisa we-split point grind ubonakala kakhulu ku-135° kunokuba ubungaba njalo engela eqondile.
Ngamafuphi: ukugaya okuhlukaniswe ngamaphoyinti kushintsha okwenzekayo emphethweni we-chisel, kanti i-engeli engu-135° ishintsha indlela umthwalo ovela kulokho kugaya osakazwa ngayo kulo lonke iphuzu. Akukho okunye okungathatha indawo yomunye — kuyizingxenye ezihambisanayo zenhloso efanayo yokuklama.
Kusho ukuthini lokhu kumthengi
Incazelo yephuzu lokuhlukaniswa elingu-135° ichaza i-geometry ehlosiwe, hhayi umphumela oqinisekisiwe. Ukuthi leyo nhloso iyafezwa yini kuncike ngokuphelele ekuqondeni kokugaya, futhi igebe phakathi kwalokhu okubili libonakala ngezindlela ezibikezelwayo:
• Ukuhamba kuyaqhubeka naphezu kwelebula le-split point.Uma ukugaya kwesibili onqenqemeni lwe-chisel kungajulile, kungalingani, noma kungangeni phakathi, unqenqema lwe-chisel lufinyezwa kuphela, futhi i-drill isabonisa ukuthi indlela yokuhamba kufanele inciphise ukugaya.
• I-engeli yephuzu engaguquki phakathi kweqoqo.Iqoqo elichazwe njengo-135° kodwa elisukela kumadigri amaningana noma yiluphi uhlangothi luzosebenza ngokungaguquki kusukela kwesinye isiqephu kuya kwesinye — ezinye izingcezu ziqala ngokuhlanzeka, ezinye zisebenza eduze nephuzu elijwayelekile.
• Imiphetho yamaphuzu ahlukene angalingani.Uma imiphetho emibili yokusika yesibili engezwe yi-split point grind ingalingani ngobude noma nge-engeli, inzuzo yokuma phakathi iyancishiswa ngendlela efanayo ne-standard lip grind engalingani ebangela ukuhamba, futhi iphutha kungaba nzima ukulibona ngaphandle kokuhlola kahle isihloko.
Akukho kulokhu okubonakala ngokufunda ishidi lemininingwane noma isihloko somkhiqizo. Kubonakala endleleni i-drill eqala ngayo umgodi — okuyiyona kanye i-geometry yamaphuzu ehloselwe ukuyilawula kwasekuqaleni.
Indlela Abathengi Abangakuqinisekisa Ngayo
Ukuhlola okumbalwa kuhlukanisa iphuzu langempela lokuhlukaniswa okungu-135° nelebula elisetshenziswa ku-grind ejwayelekile:
• Cela idatha yokuhlola i-engeli yephuzu,hhayi nje i-nominal angle ephepheni le-spec. Ukufundwa kwephrojektha noma i-point-angle gauge kulo lonke isampula kuzobonisa ukuthi i-angle ibanjwe njalo yini, hhayi nje ukuthi ifunwe.
• Hlola ukuthi ngabe i-drill isadinga ukubhobozwa phakathi ukuze iqale kahle.Iphuzu lokuhlukaniswa elenziwe kahle kufanele liqale ngokungabaza okuncane kakhulu kunephuzu elijwayelekile ezintweni ezifanayo — uma lingakwenzi lokho, ukugaya kwesibili akwenzi umsebenzi walo.
• Hlola i-tip ngaphansi kokukhulisa ukuze ubone ukuthi i-symmetry ingakanani.Izinqe ezimbili zokusika zesibili phakathi nendawo kufanele zilingane ngokubonakalayo nangobukhulu; ukungalingani lapha kuyiphuzu elihlukanisiwe elilingana nokugaywa kwezindebe okungalingani.
Njengoba kunjalo ngokulingana kokugaya okuxoxwe ngakho esihlokweni esandulele, inhloso yokuklama ngemuva kwephuzu lokuhlukaniswa elingu-135° ubunjiniyela obuhle — umbuzo wanoma yimuphi umthengi uhlala uwukuthi ngabe inqubo yokugaya ngemuva kwelebula iyayiletha ngempela, njalo, inqwaba ngenqwaba.
Mayelana nalolu chungechunge
Kungani Ama-Drill Bits Ehluleka uchungechunge lobuchwepheshe olubhalwe yithimba lethu lokukhiqiza. Isihloko ngasinye sigxile esicini esisodwa esiqondile ekusebenzeni kwama-drill bit — kusukela ezintweni ezingavuthiwe kuya ekupakisheni. Umgomo ulula: ukusiza abathengi baqonde ukuthi bathengani ngempela, nokuthi yimiphi imibuzo okufanele bayibuze.
