1.I-drill yokulola ngokuqhelekileyo ithatha ivili lokusila kunye nobukhulu be-particle ye-46 ~ 80 mesh, kwaye ukuqina yi-medium-soft grade aluminium oxide grinding wheel.Ukugaya ikona yangaphandle yevili lokugaya kwi-radius encinci ye-fillet, ukuba i-fillet radius inkulu kakhulu, umgca wokusika oyintloko uya konakaliswa xa ugaya i-chisel edge.
2.Xa ii-drill bit iyaphola, uxinzelelo oluqhutywa yii-drill bit ngexesha lokulola akufanele libe likhulu kakhulu.Ngokuqhelekileyo, ukupholisa umoya kusetyenziswa.Ukuba kuyimfuneko, kufuneka ipholiswe ngokuntywila emanzini ukukhusela ukuqina kwenxalenye yokusika i-drill bit ekuncitshisweni ngokugqithiswa kwe-annealing.
3.Umda wetshiseli womgangathotwist drillinde, ngokubanzi 0.18D (D ibhekisa kwidayamitha yedrill bit), kunye ne-rake angle kwi-chisel edge inexabiso elikhulu elibi.Ngoko ke, ukusika kwi-chisel edge yi-extrusion xa ubhobhoza Ngexesha elifanayo, ukuba i-chisel edge ide, umphumo wayo wokugxila kunye nokuzinza kuya kuba yimbi.Ngoko ke, kwi-drills enobubanzi obungaphezulu kwe-5mm, i-edge ye-chisel kufuneka ifinyezwe, kwaye i-engile yehariki kufuphi nomphetho wetshizi kufuneka yandiswe ngokufanelekileyo.Ukuphucula ukusebenza kokusika kwei-drill bit.
Ukusila komphetho wetshizi kufuneka kugqitywe.Injongo yokusila edge kukwenza mfutshane incam yetshisel, kodwa incam yetshiseli ayinakulungiswa ibe mfutshane kakhulu.Umphetho wetshizili omfutshane kakhulu awukwazi ukunciphisa ukuxhathisa kwesondlo., kwinkqubo yokunciphisa umgca we-chisel, gaya i-angle ye-rake engalunganga kumacala omabini omgca we-chisel kangangoko kunokwenzeka.Ukunyusa ngokufanelekileyo i-angle ye-rake kule ndawo kunokunciphisa ukuxhathisa ukusika ngexesha lokusika kwaye wenze yonke inkqubo yokomba ikhawuleze.
4.Ukuba i-drill yondliwe ngesandla.I-angle ye-apex inokuncitshiswa ngokufanelekileyo ngexesha lenkqubo yokulola.Ngenxa yokuba uxinzelelo lokutya kwe-drill yesandla sombane alunelanga, ukunciphisa ngokufanelekileyo i-angle ye-apex kunokunyusa uxinzelelo olulungileyo lomgca wokusika kwindawo yokusika.
5.Ukuba ububanzi bomngxuma kunye neemfuno zobunzima bomngxuma owenziweyo azikho ngqongqo kakhulu, imiphetho emibini yokusika inokucolwa ngokufanelekileyo ukuba ingalingani ngokupheleleyo.Nangona i-diameter yomngxuma iya kunyuka kwisiseko sokuqala ngexesha lenkqubo yokomba, inokunciphisa kakhulu ingxabano phakathi kwe-drill bit edge kunye nodonga lomngxuma kunye nokunciphisa amandla okusika.Akukho fomyula ingqongqo yokulola isuntswana le-drill, efuna ngokuthe ngcembe ukuqokelela amava okusebenza kwinkqubo eyiyo yokusebenza, ulingo oluphindaphindiweyo, uthelekiso lwamanyathelo, kunye nokuqwalaselwa, kunyei-drill bit inokulolwa kakuhle.
