Ho theosa le nalane ea ho cheka sebakeng sa oli, basebetsi ba lekile ho ntlafatsa ts'ebetso ea mochini oa ho cheka. Likhopolo tse fapaneng tsa ho itšeha, meralo le lisebelisoa li kentsoe ts'ebetsong ho eketsa Rate of Penetration (ROP), khanyetso ea ho roala, le bophelo bo felletseng. Ho fihla ha PDC cutter (Polycrystalline Diamond Compact Cutter) bohareng ba lilemo tsa bo-1970 ho ile ha qala motsamao butle butle ho tloha ho "roller cone bit" ho ea ho shear cutter bit.


Litšobotsi tsa sekhechana sa PDC joalo ka ho hanyetsa tšusumetso le khanyetso ea abrasion li bohlokoa. Meeli ea mocheso le ho hanyetsa phello ea sehahi sa PDC li ile tsa totobatsoa e le libaka tsa ntlafatso.


Ho tsitsa ha mocheso ke botsitso ba molek'hule ka mocheso o phahameng. Ka laboratoring, re beha li-cutters tsa PDC tlas'a 700-750 ℃ ​​bakeng sa metsotso e 10-15 le ho hlahloba maemo a lera la daemane ka mor'a ho pholile ha tlhaho moeeng ho bona hore na li-PDC Cutters li tsitsitse ka ho lekaneng tlas'a maemo a phahameng a mocheso. Hangata, ts'ebetso ena e ne e tla bapisa boleng ba PDC cutter pele ho teko le ka mor'a tlhahlobo, joalo ka ho hanyetsa ho apara le ho hanyetsa tšusumetso; Ho pholisa sekhechana sa PDC nakong ea tlhahlobo ea VTL ho lumella motho ea sehang hore a lahle mocheso ho tloha sebakeng se sehang ho ea mokelikeli. Teko e omileng kapa e chesang e hloka hore sekhechana se felise mocheso ka ho its'ireletsa ho WC substrate mme hangata se lebisa ho senyeha ha mochini, oxidation le graphitization ea daemane. Teko ea laboratoring e omileng kapa e chesang e etsisa hantle maemo a ho cheka ho tebileng, ho chesa, le ho phunya ho kang ho ka finyelloang lits'ebetsong tse ngata tsa mocheso oa mocheso.

Batho ba bangata ba qala ho hlokomela hore mocheso o sa laoleheng nakong ea brazing o ama khatello ea ka hare ea masala a li-cutters tsa PDC. Sena se lebisa ho hloleheng ha tšebeletso pele ho nako. Batho ba bangata ba tla beha molato oa PDC cutter bakeng sa sena hobane ha ba tsebe mathata a ka bakang mocheso oa ho chesa. Ba qosa moetsi oa li-cutter oa PDC, athe ha e le hantle e ne e le ts'ebetso ea bona ea brazing e bakileng bothata. PDC cutter e neng e e-na le botsitso bo botle ba mocheso nakong ea ts'ebetso ea brazing e tla ba e ntle haholo ho boloka thepa, haholo-holo bakeng sa 'maraka oa ho lokisa.


Bareki ba ZZbetter ba lokeloa ke tse molemohali. Ke ka lebaka leo re u fang boiphihlelo ba bareki ba A+, melemo ea rona:

1. Botsitso bo phahameng ba mocheso, ho hanyetsa ho apara, le ho hanyetsa tšusumetso

2. Ho tsamaisoa ka potlako nakong ea matsatsi a 5

3. Customized boholo bo amohelehang

4. Odara ea mohlala e teng
