Kunzima ngokwenene ukuchaza umgangatho wesizathu sokulungiswa komngxuma
Ukuba umngxuma unonyamezelo olungqongqo okanye iimfuno zokugqiba komphezulu, ukusetyenzwa kwesibini okufana nokukruqula okanye ukubuyisela kwakhona ngokuqhelekileyo kugqibezela umngxuma kubungakanani bokugqibela bomatshini.Kwezi meko, elona xabiso liphambili le-drill bit inokuba kukugrumba imingxunya emininzi kangangoko kunokwenzeka ngokukhawuleza, kwaye yintoni abasebenzisi abanokuyibona kukuba ingaba indawo ichanekile.
Kodwa oku akusoloko kunjalo.Kwezinye izicelo, ukuchitha ixesha elininzi kunye neenzame kunokunceda i-drill bit ihlangabezane nemigangatho yomgangatho kumsebenzi omnye.Kungenjalo, kunokumiselwa ukuba umgangatho wokugrumba uchaphazela ukukwazi kwayo ukwamkela ukusetyenzwa kwenqanaba eliphezulu kwesibini.Umzekelo, ukuba ukugrumba ngesantya esiphezulu kakhulu, ubushushu bunokubangela ukuba imathiriyeli isebenze nzima, nto leyo enokubufutshane kakhulu ubomi bempompo kwaye loo nto inokwenza kube nzima kakhulu ukucofa.
Ukuba acarbide drill bit drillsImingxuma emi-2 okanye engama-200, ingahluka;Ukuba yimingxuma engama-200, ugxininiso lomgangatho lunokuba ikakhulu kwisantya (ukusebenza) kokugqiba umsebenzi;Ukuba lo msebenzi ufuna kuphela imingxuma emi-2, ukuchitha ixesha elininzi kunye nomgudu ngexesha lenkqubo yokugaya, okanye ukusebenzisa izixhobo ezilungiselelwe ngokukodwa ukugaya kunye nokukhupha imingxuma kumsebenzi omnye, kunokuvelisa imingxuma ehlangabezana neenkcukacha zomgangatho ngaphandle kweenkqubo ezongezelelweyo.
Mhlawumbi kukho imibuzo emithathu ethi qatha engqondweni yam apha
1.Ingaba ukunyamezela komngxuma kudibene.
2. Ingaba iyahlangabezana neemfuno zokusetyenzwa komngxuma.
3. Ukuba ukugxila kulungile.
Amasuntswana e-Carbide drill asetyenziswa kwiinkalo ezininzi, kodwa uninzi lwetekhnoloji alukahoywa.Uyilo lwee-engile ezijikelezayo lubaluleke kakhulu, njenge-engile ejikelezayo ephantsi okanye amasuntswana e-groove drill, afaneleke kakhulu kwimathiriyeli ye-chip emfutshane efana nentsimbi etyhidiweyo kunye ne-ductile iron.Ngokomzekelo, i-angle ye-spiral ye-20-30 ° inceda ukugrumba jikelele kwizinto ezahlukeneyo ezinzima, njengoko le angle inceda ukususa iitshiphusi.
Nangona kunjalo, i-aluminium kunye nobhedu zivame ukuba nee-angles eziphezulu ze-helix, ezibonelela ngesiphumo sokuxela kwangaphambili kunye nokunceda ekususweni kwe-chip.Ukukhetha i-drill bits eneempawu ezichanekileyo zezixhobo ezithile kunye nokusetyenziswa kuya kwandisa ubomi besixhobo kwaye kufezekiseke kakuhle.
Kukwakho umahluko obonakalayo kwiingubo.Ngokuqhelekileyo, umzekelo, ezinye iibhithi zokubhola ziya kusebenzisa i-coating edibeneyo enokuthi isebenze ngokupheleleyo, kuquka i-titanium kunye ne-chromium kunye ne-titanium silicon layer.
I-silicon inika i-coating ephezulu yokuthambisa, ngoko ke iitshiphusi zinokutyibilika kwaye zithintele ukwenziwa kwe-chip buildup.Ukuphepha i-chip buildup kuyisitshixo sokugcina isakhono esilungileyo sokusika isixhobo kunye nokuphepha ukushiya umkhondo kudonga lomngxuma.
Ezinye iingubo ezintsha zidityaniswe kunye nesantya esiphezulu sokususa izinto, okubangela ukuba iipores zigudiswe kakuhle.Ezi zogquma kufuneka zikwazi ukumelana nobushushu obuveliswa yintshukumo yesantya esiphezulu.
1. Iinkcukacha zokulawula ii-drill bit
Ukukhethwa kwemivalo efanelekileyo kunye nomgangatho wemingxuma sele iqalile ukusuka kuyilo lwenkqubo.Ukuba ukubaleka kukhulu kakhulu, kuyakuncama ukuchaneka, ukuguda, kunye nobunzulu bomngxuma.Ubungqingqwa obufanelekileyo kwincam ye-drill bubalulekile ekugcineni uzinzo xa i-drill bit idityaniswa nezinto ezicwangcisiweyo, ukuze kuthintelwe i-drill bit ukuba ibe nkulu kakhulu kwaye i-offset, enokubangela ukuba umngxuma ube mkhulu kakhulu okanye uchaphazele i-drill bit. ukuthi tye.
Xa iimfuno zomgangatho zibandakanya ukuphucula ukunyamezela kunye nokugqitywa kwendawo, ukutshintsha ukusuka kwi-ligament enye ukuya kwi-double ligament kwi-drill bits kunokuba luncedo.
Le miphetho izinzisa i-drill bit ngokubonelela ngamanqaku amane oqhagamshelwano emngxunyeni kwaye inike umphumo wokupholisa ukushiya ukugqiba okuhle kakhulu.I-double ligaments inokusebenza njengesikhokelo sokugcina i-drill bit ihamba phambili kumgca othe tye, ngakumbi kwimingxuma enzulu.Inokuthintela i-drill bit ukuba ibe nkulu kwaye ishukume, ngaloo ndlela inikeze umngxuma ojikelezayo.
Nangona i-double ligament drill bit ivelisa umgangatho olungileyo kwizinto ezimfutshane ze-chip, kuyacetyiswa ukuba usebenzise i-drill ye-ligament drill bit enye xa izinto zivelisa i-chips ezikhulayo.Kwizinto ezinde ze-chip ezifana ne-aluminium okanye insimbi engenasici, i-ligament drills enye yinto ekhethiweyo.Ukusebenzisa i-double ligament stainless steel drill bit kunokubangela ukuba ii-chips zingene kwindawo yokudibanisa phakathi kwe-drill bit kunye nezinto eziphathekayo.
Ukulawula ukuphuma ngomnye umba ophambili womgangatho womngxuma.Ukutsiba kakhulu kunokubangela ukuba i-aperture esetyenzisiweyo ibe nkulu, kwaye njengoko isantya se-drill sikhula kwaye sijikeleza, kuya kubangela ukuba i-drill ibhobhoze imingxuma emikhulu kunye nenkulu.
Amasuntswana e-drill amade angakhokelela ekuqineni kunye nokungcangcazela.Ezi ntshukumo, ngakumbi ezo kunzima ukuzibona nge-drill bit encinci, zinokubangela ukuba i-drill bit iphuke kwaye ishiye i-blade ephukileyo kwindawo engaphakathi yomngxuma.
2. Ukulawula ukusika ulwelo
Ulawulo olululo lwesipholisi, kuqukwa nokugcina ugxininiso lwesipholisi olululo, ukuhluzwa, kunye noxinzelelo, lubalulekile kwizicelo zokomba.
Ugxininiso lwesipholisi olufanelekileyo lunyusa ukuthambisa ngelixa lususa ubushushu kumda wokusika wento yokubhola.Ukuhluza kunokususa izinto ezingcolisa isinyithi kunye nezinye izinto, ngaloo ndlela kuphuculwe ukusebenza kokomba kunye nokuthintela iingxaki ezinje ngokuvaleka komngxuma wokupholisa kumasuntswana okomba amancinci.
Ukuthintela iitshiphusi ekungeneni eludongeni phakathi kwentwana yokomba kunye nezinto ezicutshungulwayo kubalulekile kumgangatho womngxuma.Ubume kunye nombala wezi chips kunokunceda umqhubi azi ukuba umgangatho wemingxuma ebhodlwe yi-drill bit ilungile okanye imbi.
Kubalulekile ukuba i-chip yokususa i-groove ye-drill bit ivelise iitshiphusi ezintle ze-conical.Iitshiphusi ezimbini ukuya kwezintathu eziphothiweyo okanye eziphothiweyo zinokuphelela kwi-chip chute kwaye zihlikihle kwaye zikrwele macala omabini omngxuma.Oku kukhuhlana kunokubangela uburhabaxa bomphezulu.
Umva we-chip kufuneka ube yisilivere kwaye ubengezelele.Ngokungafaniyo nombala oluhlaza okwesibhakabhaka owubonayo ngexesha lokusila (kuba kuthetha ukuba ubushushu bungena kwi-chips, i-blue imele ukuba i-machining yakho yomngxuma ivelisa ubushushu obukhulu kwi-edge yokusika. Oku bushushu kuya kubangela ukuba i-blade igqoke ngokukhawuleza.
