1. Ukusebenza kakuhle kokwakhiwa kuphantsi, ngokukodwa ngenxa yexesha eliphezulu lokuphakamisa isixhobo sokugaya kunye nokusebenza okuphantsi kombhobho wokubhobhoza ukuhambisa uxinzelelo lokugaya.
indlela yokujongana nemeko:
(1) Yandisa ubude bentwana ye-drill ukunyusa ubungakanani bebhola yebhola nganye;
(2) Isixhobo sokomba sixhotyiswe nge-vent yokunyusa isantya sokomba;
(3) Ukuba awungeni etyeni, zama ukusebenzisa ibha yokukhuhlana, ukuze ugcine ixesha lokuvula.
2. Isantya sokungaphumeleli kombhobho we-drill sikhuphuka ngokukhawuleza. Emva kokwandiswa kombhobho wokubhobhoza, umlinganiselo obhityileyo wombhobho wokubhoboza awukho ngqiqweni, kwaye ulwakhiwo kufuneka luthwale itorque enkulu kunye noxinzelelo, ngakumbi umbhobho wokutshixa umatshini uhlala uvulwa emhlabeni, ngoko ke izinga lokungaphumeleli kombhobho wokubhoboza liya kuthi ga ngoku. vuka ngokukhawuleza.
indlela yokujongana nemeko:
(1) Indawo ekusetyenzwa kuyo kufuneka igudiswe kwaye iqine kangangoko ukuze kuncitshiswe ujingi lwesixhobo sokomba;
(2) Lungisa inkqubo yokulinganisa rhoqo ukwenza umbhobho wokomba usebenze ngokuthe nkqo;
(3) Akuvumelekanga ngokungqongqo ukukrazula i-rig ngexesha lokugaya ngoxinzelelo;
(4) Yongeza i-centerizer kumbhobho wokubhobhoza.
3. Ukutenxa komngxuma wemfumba, esona sizathu siphambili kubunzima obungalinganiyo kunye nobulukhuni bokubunjwa, ukuncitshiswa kwentsimbi iyonke emva kokwandiswa kwentonga ye-drill, kunye ne-gap eyongezelelekileyo yesixhobo sokubhola emva kobude besixhobo sokubhola.
indlela yokujongana nemeko:
(1) Ukwandisa ubude bezixhobo zokomba;
(2) Yongeza iringi ye-holrighizer kwintonga yokubhola;
(3) Yongeza isixhobo esichasene nobunzima kwindawo ephezulu ye-drill bit, kwaye usebenzise uxinzelelo kumngxuma ongezantsi, ukuze isixhobo sokugaya sibe nomsebenzi wokuzixhasa xa ubhobhoza.
4. Iingozi ezihlala rhoqo emngxunyeni, ngokukodwa zibonakaliswa ngokuwa okungazinzanga kodonga lomngxuma.
indlela yokujongana nemeko:
(1) Ngenxa yexesha elide lokwakhiwa kwemfumba enzulu, ukuba umphumo wokukhusela udonga awulungile, udonga lomngxuma luya kungazinzi, kwaye udaka oluphezulu kufuneka lulungiswe;
(2) Indawo yokomba inesikhala sokunciphisa impembelelo kunye nokufunxa eludongeni lomngxuma xa kusonjwa.
