E le likotoana tse peli tse sebelisoang ka ho fetisisa tsa ho cheka tsa lisebelisoa tse fapaneng, lisebelisoa tsa tšepe tse lebelo le holimo le li-carbide drill, litšoaneleho tsa tsona ke life, melemo le mathata afe, le hore na ke lisebelisoa life tse molemo ha li bapisoa.
Lebaka leo ka lona li-drill tsa tšepe tse nang le lebelo le phahameng li sebelisoang haholo ke hore thepa ea tšepe e phahameng e na le khanyetso e matla ho mocheso o phahameng le ho apara ho hanyetsa, 'me e ke ke ea hlahisa liphello tsa deformation le ho apara nakong ea ho itšeha ha mocheso o phahameng.Ehlile, e tiisitsoe butle-butle ka tšebeliso ea nako.Ho tla ba le tahlehelo, empa lintho tse etsoang ka nako e se nang tšenyo li bohlokoa haholo.Taba ea bobeli, ho tiea ha liboro tsa tšepe tse lebelo le holimo ho feta ba lisebelisoa tse ling.Lisebelisoa tsa ho cheka ha lia lokela ho boloka botsitso le litlhoko tse thata feela.E boetse e phahame haholo.Ntle le ho tiea ho hoholo, karoloana ea ho phunya e atisa ho phunya, e lebisang bophara bo sa tsitsang ba lesoba ha karolo ea ho phunya e felile.
Monyetla o moholo oa li-drill tsa carbide ke boima ba bona bo phahameng.Molemo oa boima bo phahameng o lumella li-drill tsa carbide ho tobana le litšepe tse ling tse ngata tse thata haholo.Leha ho le joalo, bofokoli bo boholo ka ho fetisisa ba li-drill tsa carbide ke boima bo fokolang, bo boreleli haholo ebile bo bonolo ho phunya.Tabeng ea likoti tse tebileng, haeba ho se na ts'ebetso e khethehileng e le karolo ea ts'ehetso ea carbide drill e hole le phello ea sekhahla se phahameng sa tšepe, ha e le hantle, ho thatafala ha tšepe ea tšepe e phahameng ho ka mamella.
Ka kakaretso, likotoana tsa tšepe tsa lebelo le phahameng le li-drill tsa carbide li na le litšobotsi tse ts'oanang, empa ntlha e hlahelletseng ea tšepe ea lebelo le phahameng e lutse ka thata e ntle, athe ntlha e hlahelletseng ea li-drill tsa carbide ke boima bo phahameng, le phapang ea eona. mefokolo ke hore ho thatafala ha likotoana tsa ho phunya tšepe ka lebelo le phahameng ha hoa lekana, 'me tšepe e thata e phahameng e sebetsoa.
Ha e thibane, 'me boima ba li-drill tsa carbide bakeng sa ho sebetsana le masoba a tebileng ha bo botle, kahoo ha u khetha ho cheka, u tlameha ho khetha mochine o lumellanang le boemo bo itseng.Ka mohlala, liboro tsa tšepe tse lebelo le phahameng tse entsoeng ka koporo, tšepe le aluminium li loketse ho feta li-drill tsa carbide.Sekotoana sa DTH sa hardness high-hardness carbide se tla tšoarella nako e telele ho feta sekhahla sa tšepe sa lebelo le phahameng.
