Ii-Drill Bits zazisa: Isikhokelo sabaQalayo kwii-Wood Drill Bits!

intshayelelo

Ukusebenza ngomthi bubugcisa obufuna ukuchaneka kunye nobugcisa, kwaye eyona nto iphambili kumsebenzi wobugcisa sisixhobo esisisiseko - isixhobo sokugrumba ngomthi. Nokuba ungumchweli onamava okanye umntu othanda izinto zakhe, ukwazi indlela yokukhetha nokusebenzisa isixhobo sokugrumba esifanelekileyo kubalulekile kwiprojekthi yokusebenza ngomthi ephumelelayo.

Kule sikhokelo sibanzi, siza kujonga kwiingxaki zeebhithi zokubhola ngomthi, sihlolisise iintlobo ezahlukeneyo, ubukhulu, izinto kunye neengubo ezinegalelo ekusebenzeni kwazo.

Masiqale sihlolisise izixhobo ezisisiseko ezenza umsebenzi omhle wokhuni.

Ukwazisa nge-Wood Drill Bit

Izinto eziphathekayo

Izinto ezininzi ezahlukeneyo zisetyenziselwa okanye zisetyenziselwa ii-drill bits, kuxhomekeke kwindlela efunekayo yokufaka.

I-Tungsten CarbideI-Tungsten carbide kunye nezinye ii-carbide ziqinile kakhulu kwaye zinokugrumba phantse zonke izinto, ngelixa zibambe umphetho omde kunezinye iibhithi. Le nto ibiza kakhulu kwaye ibuthathaka kakhulu kuneentsimbi; ngenxa yoko zisetyenziselwa ikakhulu iincam zokugrumba, iziqwenga ezincinci zezinto eziqinileyo ezinamathele okanye ezibotshelelwe kwincam yenkqutyana eyenziwe ngesinyithi esingenalo uqilima.

Nangona kunjalo, kuya kuqheleka kwiindawo zemisebenzi ukusebenzisa ii-solid carbide bits. Kwiisayizi ezincinci kakhulu kunzima ukufaka iincam ze-carbide; kwezinye iifektri, ngakumbi ukwenziwa kweebhodi zesekethe eziprintiweyo, ezifuna imingxunya emininzi enobubanzi obungaphantsi kwe-1 mm, kusetyenziswa ii-solid carbide bits.

I-PCDIdayimani yePolycrystalline (PCD) iphakathi kwezona zixhobo zinzima kakhulu kwaye ngenxa yoko ayigugi kakhulu. Iqulathe umaleko weesuntswana zedayimani, eziqhele ukuba zinobukhulu obumalunga ne-0.5 mm (0.020 in), ezidityaniswe njenge-sintered mass kwi-tungsten-carbide support.

Iibhithi zenziwa kusetyenziswa le nto ngokufaka iziqwenga ezincinci kwincam yesixhobo ukuze kwenziwe imiphetho yokusika okanye ngokufaka i-PCD emthanjeni kwi-"nib" ye-tungsten-carbide. I-nib ingafakwa kamva kwi-shaft ye-carbide; emva koko ingagaywa ibe yi-geometries eyinkimbinkimbi enokubangela ukuba i-braze ingasebenzi kakuhle "kwiziqwenga" ezincinci.

Iibhithi ze-PCD zihlala zisetyenziswa kwimizi-mveliso yeemoto, yeenqwelo-moya, nakwamanye amashishini ukubhola ii-alloys ze-abrasive aluminium, iiplastiki eziqinisiweyo ze-carbon-fiber, kunye nezinye izinto ezirhabaxa, nakwiindawo apho ixesha lokungasebenzi komatshini lokutshintsha okanye ukulola iibhithi ezigugileyo libiza kakhulu. I-PCD ayisetyenziswa kwiintsimbi ze-ferrous ngenxa yokuguguleka okugqithisileyo okubangelwa kukusabela phakathi kwekhabhoni kwi-PCD kunye nesinyithi kwisinyithi.

Intsimbi

Iibhithi zentsimbi ezithambileyo ezinekhabhoni ephantsiazibizi kakhulu, kodwa azibambeleli kakuhle kwaye zifuna ukulolwa rhoqo. Zisetyenziselwa kuphela ukugrumba imithi; nokusebenza ngemithi enzima endaweni yemithi ethambileyo kunokunciphisa ubomi bayo ngokubonakalayo.

Iibhithi ezenziwe ngeintsimbi enekhabhoni ephezuluzihlala ixesha elide kuneiibhithi zentsimbi ezinekhabhoni ephantsingenxa yeempawu ezibangelwa kukuqina nokulungisa izinto. Ukuba zishushu kakhulu (umz., ngokufudumeza okukhuhlanayo ngexesha lokubhoboza) ziyaphelelwa ngumoya, nto leyo ebangela ukuba zibe buthathaka. Ezi nxalenye zingasetyenziswa emthini okanye kwisinyithi.

Intsimbi ekhawulezayo (i-HSS) luhlobo lwentsimbi yesixhobo; ii-HSS bits ziqinile kwaye zimelana kakhulu nobushushu kunentsimbi enekhabhoni ephezulu. Zingasetyenziselwa ukugrumba isinyithi, imithi enzima, kunye nezinye izinto ezininzi ngesantya esiphezulu sokusika kunee-carbon-steel bits, kwaye zithathe indawo yee-carbon steels kakhulu.

Ii-alloys zentsimbi yeCobaltziintlobo ngeentlobo zentsimbi ekhawulezayo equlethe i-cobalt engaphezulu. Zigcina ubulukhuni bazo kumaqondo obushushu aphezulu kakhulu kwaye zisetyenziselwa ukugrumba intsimbi engagqwaliyo nezinye izinto eziqinileyo. Eyona ngxaki inkulu yeentsimbi ze-cobalt kukuba zibuthathaka ngakumbi kune-HSS eqhelekileyo.

Ukwaleka

I-oxide emnyama

I-black oxide yingubo emnyama engabizi kakhulu. Ingubo ye-black oxide inika ukumelana nobushushu kunye nokuthamba, kunye nokumelana nokugqwala. Ingubo inyusa ubomi bentsimbi ekhawulezayo.

I-nitride yeTitanium

I-Titanium nitride (TiN) yinto eqinileyo kakhulu yesinyithi enokusetyenziswa ukugquma intsimbi ekhawulezayo (ngesiqhelo i-twist bit), yandisa ubomi bokusika ngokuphindwe kathathu nangaphezulu. Kwanasemva kokulolwa, umda ophambili wogquma usabonelela ngokuphucula ukusika kunye nobomi bonke.

Iimpawu

i-engile yenqaku

I-engile yenqaku, okanye i-engile eyenziwe kwincam ye-bit, imiselwa zizinto eziza kusebenza kuzo i-bit. Izinto eziqinileyo zifuna i-engile yenqaku elikhulu, kwaye izinto ezithambileyo zifuna i-engile ebukhali. I-engile yenqaku elifanelekileyo lobunzima bezinto ezisetyenzisiweyo ichaphazela ukuzulazula, ukuxokozela, ukuma komngxuma, kunye nesantya sokuguguleka.

ubude

Ubude obusebenzayo be-bit bumisela ukuba umngxuma unokugrunjwa nzulu kangakanani, kwaye bumisela nokuqina kwe-bit kunye nokuchaneka komngxuma ophumayo. Nangona ii-bits ezinde zinokugrumba imingxunya enzulu, ziguquguquka ngakumbi oko kuthetha ukuba imingxuma eziyigrumbayo inokuba nendawo engachanekanga okanye izulazule ukusuka kwi-axis ekujoliswe kuyo. Ii-twist drill bits zifumaneka ngobude obuqhelekileyo, obubizwa ngokuba yi-Stub-length okanye i-Screw-Machine-length (mfutshane), ubude be-Jobber obuqhelekileyo (obuphakathi), kunye nobude be-Taper okanye i-Long-Series (ende).

Uninzi lwee-drill bits ezisetyenziswa ngabathengi zine-straight shanks. Kwi-hard drill kwimizi-mveliso, kusetyenziswa ii-bits ezine-tapered shanks ngamanye amaxesha. Ezinye iintlobo ze-shank ezisetyenziswayo ziquka iinkqubo ezahlukeneyo ze-hex-shaped, kunye neenkqubo ezahlukeneyo zokukhulula ngokukhawuleza.

Umlinganiselo wobubanzi nobude be-drill bit udla ngokuba phakathi kwe-1:1 kunye ne-1:10. Umlinganiselo ophezulu kakhulu unokwenzeka (umz., ii-twist bits "zobude beenqwelo-moya", ii-pressed-oil gun drill bits, njl.njl.), kodwa okukhona umlinganiselo uphezulu, kokukhona umngeni wobugcisa wokuvelisa umsebenzi olungileyo ukhula.

Iintlobo zee-Drill Bits:

I-blade yesarha Ukuba ayisetyenziswanga ngoko nangoko, kufuneka ibe tyaba okanye isebenzise umngxuma ukuze ixhonywe, okanye ezinye izinto azinakubekwa kwii-blade zesarha zeenyawo ezithe tyaba, kwaye kufuneka kuqwalaselwe ukufuma kunye nokuthintela ukugqwala.

I-Brad point bit (i-Dowel Drill Bit):

I-brad point drill bit (ekwaziwa ngokuba yi-lip and spur drill bit, kunye ne-dowel drill bit) yindlela eyahlukileyo ye-twist drill bit eyenzelwe ukugrumba umthi.

Sebenzisa i-drill bit yomthi othe tyaba okanye i-spiral drill bit, efanelekileyo kwimisebenzi apho kufuneka kufihlwe khona iibholiti okanye amantongomane.

Iibhithi zokubhola zeBrad point ngokuqhelekileyo zifumaneka ngobubanzi ukusuka kwi-3–16 mm (0.12–0.63 in).

I-Drill Bit edlula kwimingxuma

Umngxuma odlulayo ngumngxuma odlula kuyo yonke into yokusebenza.

Sebenzisa i-spiral drill bit ukuze ungene ngokukhawuleza, ifanele umsebenzi wokugrumba ngokubanzi.

I-hinge sinker bit

I-hinge sinker bit ngumzekelo woyilo lwe-drill bit eyenzelwe wena kwisicelo esithile.
Kuye kwaveliswa ihinge ekhethekileyo esebenzisa iindonga zomngxuma onobubanzi obuyi-35 mm (1.4 in), ogqojozwe kwibhodi yamasuntswana, ukuze zixhase.

I-bit yeForstner

Iibhithi zeForstner, ezithiywe ngomqambi wazo, zazinemingxuma echanekileyo, esezantsi esicaba emthini, kuyo nayiphi na indlela ebhekiselele kwingqolowa yomthi. Zingasika emaphethelweni ebhloko yomthi, kwaye zingasika imingxunya egqumayo; kwezo zicelo zihlala zisetyenziswa kwiimashini zokubhola okanye iilathe endaweni yokubhola umbane ophathwa ngesandla.

Iingcebiso ezincinci zokusebenzisa ii-Wood Drill Bits

Ukulungiselela

Qinisekisa ukuba indawo yokusebenza icocekile, ususe imiqobo enokuthintela ukugrumba.
Khetha izixhobo zokhuseleko ezifanelekileyo, kuquka iiglasi zokhuseleko kunye neendlebe.

Isantya: Khetha isantya esifanelekileyo ngokusekwe kubunzima bomthi kunye nohlobo lwebhithi.
Ngokubanzi, isantya esicothayo sifanelekile kwiinkuni eziqinileyo, ngelixa isantya esikhawulezayo singasetyenziswa

Isiphelo

Ukususela ekuqondeni imiba yokukhetha uhlobo olufanelekileyo, ubungakanani, kunye nezinto ezisetyenzisiweyo ukuya ekusebenziseni iindlela eziphambili ezifana nokudala imingxunya engaboniyo, yonke into inegalelo kubungcali bokusebenza ngomthi.
