3. Matsayin Yanke Ruwa
Isasshen ruwan yankan da ya dace shine mabuɗin don rage lalacewa:
-Tasirin kwantar da hankali: Yana kawar da zafi da aka yi a lokacin yankan, yana hana samfurin daga canje-canjen nama saboda yawan zafin jiki (irin su "ablation" na kayan ƙarfe);
-Tasirin Lubricating: Yana rage juzu'i tsakanin yankan ruwan wukake da samfurin, yana rage girman yanayin, kuma yana tsawaita rayuwar sabis na yankan ruwa;
-Tasirin cire guntu: Yana kawar da kwakwalwan kwamfuta akan lokaci, yana hana kwakwalwan kwamfuta mannewa saman samfurin ko toshe yankan ruwa, wanda zai iya shafar daidaiton yanke.
Gabaɗaya, ruwan yankan ruwa na tushen ruwa (tare da kyakkyawan aikin sanyaya, dacewa da ƙarfe) ko ruwan yankan mai (tare da lubricity mai ƙarfi, dacewa da kayan karye) ana zaɓar bisa ga kayan.
4.Madaidaicin Saiti na Yankan Siga
Daidaita sigogi bisa ga halayen kayan don daidaita inganci da inganci:
- Yawan ciyarwa: Don kayan aiki mai ƙarfi (kamar babban ƙarfe na carbon da tukwane), yakamata a rage ƙimar abinci don gujewa wuce gona da iri na yankan ruwa ko lalacewar samfur; don kayan laushi, za a iya ƙara yawan abincin da ya dace don inganta haɓaka;
-Yanke gudun: Matsakaicin saurin yankan ya kamata ya dace da taurin kayan. Misali, saurin layin da aka saba amfani da shi don yankan karfe shine 20-30m / s, yayin da tukwane ke buƙatar ƙaramin sauri don rage tasiri;
-Samar da adadin abinci: Ta hanyar X, Y, Z aikin sarrafawa ta atomatik na kayan aiki, ana samun daidaitaccen ciyarwa don guje wa fashewar samfurin da ya wuce kima na adadin lokaci guda.
5.Auxiliary Role of Equipment Services
-Madaidaicin murfin kariya na gaskiya ba zai iya keɓance tarkace da hayaniya kawai ba amma kuma yana sauƙaƙe lura da yanayin yankewa da gano abubuwan da ba su da kyau a kan lokaci;
-Allon taɓawa na 10-inch na iya saita sigogi da hankali, da yin aiki tare da tsarin ciyarwa ta atomatik don fahimtar daidaitattun ayyukan da rage kurakuran ɗan adam;
-LED hasken yana haɓaka tsabtar kallo, yana ba da damar yanke hukunci akan lokaci na matsayin yankan samfurin da yanayin ƙasa don tabbatar da daidaiton ƙarshen yanke.
A ƙarshe, yankan samfurin yana buƙatar daidaita "daidaitacce" da "kariya". Ta hanyar dacewa da kayan aiki, kayan aiki, da sigogi, an kafa tushe mai kyau don shirye-shiryen samfurin na gaba (kamar niƙa, gogewa, da lalata) da gwaji, a ƙarshe yana tabbatar da gaskiya da amincin sakamakon binciken kayan aiki.
