Umshini wokusika ngokunemba ozenzakalelayo we-XYZ - ubeka isisekelo esiqinile sokulungiselela nokuhlaziya isampula ye-metallographic.

Njengesinyathelo esibalulekile ngaphambi kokuhlolwa kobulukhuni bezinto noma ukuhlaziywa kwe-metallographic, ukusika isampula kuhlose ukuthola amasampula anobukhulu obufanele kanye nezimo ezinhle zobuso ezivela ezintweni zokusetshenziswa noma ezingxenyeni, okuhlinzeka ngesisekelo esithembekile sokuhlaziywa kwe-metallographic okulandelayo, ukuhlolwa kokusebenza, njll. Imisebenzi engalungile enkambisweni yokusika ingaholela ezinkingeni ezifana nokuqhekeka, ukuguquka, kanye nomonakalo oshisa kakhulu ebusweni besampula, okuthinta ngqo ukunemba kwemiphumela yokuhlolwa. Ngakho-ke, kufanele sinake kakhulu izinto ezilandelayo ezibalulekile:

1. Ukukhethwa Kwama-Blades Okusika/isondo lokusika

Izinto ezahlukene zidinga ukufanisa ama-blade/isondo lokusika:

- Ngezinsimbi zensimbi (njengensimbi nensimbi ephonswe nge-cast iron), ama-alumina okusika ahlanganiswe ne-resin avame ukukhethwa, anobulukhuni obuphakathi kanye nokushabalalisa ukushisa okuhle, futhi anganciphisa izinhlansi kanye nokushisa ngokweqile ngesikhathi sokusika;

- Izinsimbi ezingezona i-ferrous (njengethusi, i-aluminium, ama-alloy) zithambile futhi kulula ukuzinamathela ensikeni. Ama-blade okusika idayimane/isondo lokusika noma ama-blade okusika i-silicon carbide aqoshiwe kahle/isondo lokusika kudingeka asetshenziswe ukugwema “ukudabula” ubuso besampula noma ukungcola okusele;

- Ukuze uthole izinto ezibuthakathaka njenge-ceramics nengilazi, kudingeka ama-blade/isondo lokusika ledayimane eliqinile kakhulu, futhi izinga lokuphakelwa kufanele lilawulwe ngesikhathi sokusika ukuze kuvinjelwe ukuqhekeka kwesampula.

2. Ukubaluleka kweizibambo 

Umsebenzi we-clamp ukulungisa isampula nokuqinisekisa ukuqina ngesikhathi sokusika:

-Kumasampula anezimo ezingajwayelekile, kufanele kusetshenziswe ama-clamp alungisekayo noma amathuluzi enziwe ngokwezifiso ukugwema ukuphambuka kobukhulu okubangelwa ukuthuthumela kwesampula ngesikhathi sokusika;

-Ezingxenyeni ezinezindonga ezincane nezincane, kufanele kusetshenziswe ama-clamp aguquguqukayo noma izakhiwo ezengeziwe zokusekela ukuvimbela ukuguquguquka kwesampula ngenxa yamandla amakhulu okusika;

-Ingxenye yokuxhumana phakathi kwe-clamp nesampula kufanele ibe bushelelezi ukuze kugwenywe ukuklwebha ubuso besampula, okungase kuthinte ukubonwa okulandelayo.

3. Indima Yokusika Uketshezi

Uketshezi lokusika olwanele nolufanele luyisihluthulelo sokunciphisa umonakalo:

-Umphumela wokupholisa: Ususa ukushisa okukhiqizwa ngesikhathi sokusika, uvimbela isampula ekushintsheni kwezicubu ngenxa yokushisa okuphezulu (njengokubhujiswa kwezinto zensimbi);

-Umphumela wokugcoba: Kunciphisa ukungqubuzana phakathi kwensingo yokusika kanye nesampula, kunciphisa ubulukhuni bomphezulu, futhi kwandise impilo yensingo yokusika;

-Umphumela wokususa ama-chip: Ususa ama-chip ngesikhathi esifanele ngesikhathi sokusika, uvimbele ama-chip ukuthi anamathele ebusweni besampula noma avale i-blade yokusika, okungase kuthinte ukunemba kokusika.

Ngokuvamile, uketshezi lokusika olusekelwe emanzini (olusebenza kahle ekupholiseni, olufanele izinsimbi) noma uketshezi lokusika olusekelwe kumafutha (olunokuthambisa okunamandla, olufanele izinto eziqhekekayo) lukhethwa ngokwezinto ezibonakalayo.

4. Ukusetha Okunengqondo Kwezipharamitha Zokusika

Lungisa amapharamitha ngokwezici zezinto ezibonakalayo ukuze ulinganisele ukusebenza kahle kanye nekhwalithi:

-Izinga lokuphakelwa: Ezintweni ezinobunzima obukhulu (njengensimbi enekhabhoni ephezulu kanye ne-ceramics), izinga lokuphakelwa kufanele lincishiswe ukuze kugwenywe ukugcwala ngokweqile kwensingo yokusika noma umonakalo wesampula; ezintweni ezithambile, izinga lokuphakelwa lingakhushulwa ngokufanele ukuze kuthuthukiswe ukusebenza kahle;

-Isivinini sokusika: Isivinini esiqondile sensingo yokusika kufanele sihambisane nobunzima bezinto zokwakha. Isibonelo, isivinini esiqondile esivame ukusetshenziswa ekusikeni insimbi singama-20-30m/s, kuyilapho izinto zobumba zidinga isivinini esiphansi ukuze kuncishiswe umthelela;

-Ukulawulwa kwenani lokuphakelayo: Ngokusebenzisa umsebenzi wokulawula okuzenzakalelayo we-X, Y, Z wemishini, ukuphakela okunembile kuyabonakala ukuze kugwenywe ukuqhekeka kobuso besampula okubangelwa inani elikhulu lokuphakelayo lesikhathi esisodwa.

5. Indima Esizayo Yemisebenzi Yemishini

-Isembozo sokuvikela esibonakala ngokuphelele esivalekile asikwazi nje ukuhlukanisa udoti nomsindo kodwa futhi senza kube lula ukubonwa kwesikhathi sangempela kwesimo sokusika kanye nokutholakala kwezinkinga ngesikhathi esifanele;

-Isikrini sokuthinta esingu-10 intshi singasetha amapharamitha okusika ngokwemvelo, futhi sibambisane nohlelo lokudla oluzenzakalelayo ukuze kufezwe imisebenzi ejwayelekile futhi kuncishiswe amaphutha abantu;

-Ukukhanya kwe-LED kuthuthukisa ukucaca kokubuka, okuvumela ukwahlulela ngesikhathi isikhundla sokusika isampula kanye nesimo sobuso ukuqinisekisa ukunemba kwendawo yokusika.

Ekuphetheni, ukusika amasampula kudinga ukulinganisela "ukunemba" kanye "nokuvikela". Ngokuqhathanisa imishini, amathuluzi, kanye nemingcele ngokufanele, kubekwa isisekelo esihle sokulungiselela amasampula okulandelayo (njengokugaya, ukupholisha, kanye nokugqwala) kanye nokuhlola, ekugcineni kuqinisekiswa ubuqiniso kanye nokuthembeka kwemiphumela yokuhlaziywa kwezinto.
