Imyanda isanzwe yo gucumura nimpamvu

Ikintu nyamukuru kigizwe na sima ya sima ni micro-nini ya tungsten karbide ifu yubukomere bukabije. Carbide ya sima nigicuruzwa cyanyuma cyakozwe hamwe nifu ya metallurgie hanyuma ikayungurura mu itanura rya vacuum cyangwa itanura rya hydrogen. Inzira ikoresha cobalt, nikel, cyangwa molybdenum nka binder. Gucumura ni intambwe ikomeye cyane muri karbide ya sima. Igikorwa cyo gucumura ni ugushyushya ifu igereranije nubushyuhe runaka, ukayigumana mugihe runaka, hanyuma ukayikonjesha kugirango ubone ibikoresho bifite ibimenyetso bisabwa. Uburyo bwo gucumura karbide ya sima iragoye cyane, kandi biroroshye kubyara imyanda yacumuye niba ukoze amakosa. Iyi ngingo igiye kuvuga kubyerekeye imyanda isanzwe ikorwa nicyaha gitera imyanda.

1. Gukuramo

Imyanda ya mbere isanzwe yo gucumura ni ugushonga. Gukuramo ni mugihe ubuso bwa karbide ya sima bugaragara hamwe nibice kumpande hamwe nibisasu. Byongeye kandi, bimwe bigaragara uruhu ruto ruto nk'umunzani w'amafi, guturika, ndetse no guhindagurika. Gukuramo ahanini biterwa no guhura na cobalt muri compact, hanyuma gaze irimo karubone ibora karubone yubusa muri yo, bikaviramo kugabanuka kwimbaraga zaho za compact, bikavamo gukuramo.

2. Urwobo

Imyanda ya kabiri ikunze kugaragara cyane ni imyenge igaragara hejuru ya karbide ya sima. Imyobo ifite microne irenga 40 yitwa pore. Ikintu cyose gishobora gutera ibibyimba bizatera imyenge hejuru. Byongeye kandi, iyo hari umwanda mumubiri wacumuye udatwarwa nicyuma gishongeshejwe cyangwa umubiri wacumuye ufite icyiciro gikomeye kandi gutandukanya icyiciro cyamazi bishobora gutera imyenge.

3. Ibibyimba

Ibibyimba ni mugihe hari umwobo imbere ya karbide ya sima kandi bigatera ibisebe hejuru yibice bijyanye. Impamvu nyamukuru yibibyimba nuko umubiri wacumuye wagereranije gaze. Gazi yibanze mubisanzwe irimo ubwoko bubiri.

4. Imiterere idahwitse iterwa no kuvanga ifu itandukanye.

5. Guhinduka

Imiterere idasanzwe yumubiri wacumuye yitwa deformation. Impamvu nyamukuru zo guhindura ibintu zirimo: gukwirakwiza ubucucike bwamasezerano ntabwo arimwe; umubiri wacumuye urabura cyane muri karubone; gupakira ubwato ntabwo bifite ishingiro, kandi isahani yinyuma ntiringana.

6. Ikigo cyirabura

Agace karekuye hejuru yimvune yiswe hagati yumukara. Impamvu ya centre yumukara nibintu byinshi bya karubone cyangwa ibirimo karubone ntabwo bihagije. Ibintu byose bigira ingaruka kuri karubone yumubiri wacumuye bizagira ingaruka hagati yumukara wa karbide.

7. Kuvunika

Kuvunika nabyo ni ibintu bisanzwe mumyanda ya sima ya sima. Hariho ubwoko bubiri bwibice, bumwe ni ugusenyuka, ubundi ni ibice bya okiside.

8. Kurenza gutwika

Iyo ubushyuhe bwo gucumura buri hejuru cyane cyangwa igihe cyo gufata ni kirekire, ibicuruzwa bizatwikwa cyane. Gutwika cyane ibicuruzwa bituma ibinyampeke byiyongera, imyenge iriyongera, kandi imiti ivanze igabanuka cyane. Icyuma cyibicuruzwa bitarashwe ntigaragara, kandi bigomba kongera kurasa.
