I-engile ye-vertex yetwist drillgabalala yi-118°, kodwa inokuphinda ithathwe njenge-120°.Akukho ngxaki ngokubanzi ukuba unokugqwesa ezi zakhono zi-6 zilandelayo zokulola ii-drill.
1.Ngaphambi kokugaya i-drill bit, eyona nto iphambili yokusika i-drill bit kunye ne-grinding wheel surface kufuneka ibekwe kwi-plane ethe tye, oko kukuthi, xa umgca wokusika uthinta indawo yevili lokugaya, umgca wonke kufuneka ube phantsi. .Eli linyathelo lokuqala kwindawo ehambelanayo ye-drill bit kunye nevili lokugaya.Emva kokuba indawo iseti, iya kucotha yayama ngakwindawo yevili lokusila.
2.Le engile yi-engile yangaphambili yei-drill bit.Ukuba i-angle ayilunganga ngeli xesha, iya kuchaphazela ngokuthe ngqo ubungakanani be-angle ephezulu ye-drill bit, imilo yecala eliphambili lokusika kunye ne-bevel angle ye-chisel edge.Oku kubhekiselele kubudlelwane bendawo phakathi kwe-axis ye-drill bit kunye nomphezulu wevili lokugaya, okuyi-60 °, echanekileyo ngokubanzi.Apha, ingqalelo kufuneka ihlawulwe kwindawo ethe tyaba ethe tyaba kunye nendawo ye-angular phambi kokuba i-drill ilole.Ezi zimbini kufuneka ziqwalaselwe ngokupheleleyo.Musa ukungayinaki i-angle yokumisela ngenxa yokulinganisa i-edge edge, okanye ungayihoyi i-level ye-cut edge ngenjongo yokumisela i-angle.
3.Emva kokuba umgca wokusika uthinte ivili lokugaya, kufuneka ube ngumhlaba ukusuka kwinqanaba eliphambili ukuya ngasemva, oko kukuthi, umgca wokusika we-drill udibanisa kuqala isondo lokugaya, kwaye ngokukhawuleza ugawula phantsi kunye necala lonke.Xa i-drill bit isika ngaphakathi, bamba ivili lokugaya kancinci, yenza umlinganiselo omncinci wokulola kuqala, kwaye ubeke ingqalelo ukujonga ukufana kweentlantsi, lungisa uxinzelelo kwisandla ngexesha, kwaye ubeke ingqalelo ekupholiseni kwe-drill. bit, ukuze ungavumeli ukuba umhlaba ube kakhulu, ubangela ukuba umgca utshintshe umbala, kwaye ufakwe emphethweni.Xa iqondo lokushisa elisezantsi lifunyenwe liphezulu, i-drill bit kufuneka ipholile ngexesha.
4.Le yintshukumo eqhelekileyo yokugaya i-drill.Eyona nto iphambili yokusika kufuneka ijiwuze inyuke nasezantsi kwivili lokusila, oko kukuthi, isandla esibambe umphambili we-drill kufuneka sijiwulise ngokulinganayo i-drill phezulu nasezantsi kumphezulu wevili lokugaya.Nangona kunjalo, isandla esibambe isibambo kufuneka singajingi, kwaye isibambo sangemva akufanele siguqulwe, oko kukuthi, umsila we-drill bit awukwazi ukuphakanyiswa ngaphezu kwendawo ethe tye yevili lokusila, ngaphandle koko umgca wokusika uya kuba buthuntu kwaye. ayikwazi ukusika.Eli lelona nyathelo libalulekileyo.Nokuba i-drill bit inxitywe kakuhle okanye ayikho inento eninzi yokwenza nayo.Xa ukugaya sele kugqityiwe, qalisa ukusuka emphethweni we-blade kwaye uyikhuhle kancinci ukuya kwikona yangasemva ukwenza umva we-blade ube mpuluswa.
1.Emva kokugaya enye i-cut cut, gaya enye i-cut cut.Kufuneka kuqinisekiswe ukuba umgca wokusika uphakathi kwe-axis ye-drill bit, kwaye imida yokusika kumacala omabini kufuneka ibe yi-symmetrical.Iinkosi ezinamava ziya kuqwalasela i-symmetry ye-drill tip phantsi kokukhanya okukhanyayo, kwaye ngokukhawuleza ukuyilola.I-angle yokunceda kwi-cut cut of the drill ngokuqhelekileyo i-10 ° -14 °.Ukuba i-angle yokunceda inkulu, i-cut cut incinci kakhulu, kwaye i-vibration inzima ngexesha lokugaya.Umngxuma unonxantathu okanye i-pentagonal, kwaye i-chip ifana nenaliti;i-angle yokunceda incinci, Xa ubhobhoza, amandla e-axial makhulu kakhulu, akulula ukunqumla, amandla okusika ayanda, ukunyuka kweqondo lokushisa kukhulu, intloko ye-drill itshisa ngokukrakra, kwaye akunakwenzeka ukuba uqhube.I-angle yangasemva ifanelekile ukugaya, indawo yangaphambili igxininiswe, kwaye imiphetho emibini i-symmetrical.Xa ukomba, ii-drill bitinokususa iitshiphusi kancinci, ngaphandle kokungcangcazela, kwaye i-diameter yomngxuma ayiyi kwandiswa.
2.Emva kokugaya imiphetho emibini, nikela ingqalelo ekuloleni incam yei-drill bit ngedamitha enkulu.Emva kokuba imiphetho emibini ye-drill bit iphuculwe, kuya kubakho indawo ethe tyaba kwincam yeencam ezimbini, eziya kuchaphazela ukubekwa kweziko le-drill bit.Kuyimfuneko ukuba i-chamfer ikona emva komphetho ukwenza umphezulu osicaba wencam yomphetho ube mncinci kangangoko.Indlela yokubeka i-drill bit ngokuthe tye, ilungelelanise nekona yevili lokugaya, kwaye uthele i-groove encinci kwingcambu emva kwe-blade ngokuchasene nencam ye-blade.Oku kwakhona ingongoma ebalulekileyo drill centering kunye nokusika ukukhanya.Qaphela ukuba xa ugaya i-chamfer ye-edge tip, akufanele ibe phantsi kwinqanaba eliphambili lokusika.Oku kuya kwenza i-rake angle yomgca wokusika omkhulu kakhulu, oya kuchaphazela ngokuthe ngqo ukugaya.
