(1) Ukupholisha ngokweqile Inkinga enkulu okuhlangatshezwane nayo enqubweni yokupholishwa kwansuku zonke “ukupholisha ngokweqile”, okusho ukuthi isikhathi eside sokupholisha, kuba mbi kakhulu izinga lendawo yokubumba.Kunezinhlobo ezimbili zokupholisha ngokweqile: "ikhasi lewolintshi" nelithi "pitting."Ukupholisha ngokweqile kuvame ukwenzeka ekupholiseni ngomshini.
(2) Isizathu “sekhasi lewolintshi” endaweni yokusebenza
Izindawo ezingavamile nezimaholoholo zibizwa ngokuthi “amakhasi awolintshi”.Kunezizathu eziningi zokuthi "i-orange peeling".Isizathu esivame kakhulu i-carburization ebangelwa ukushisa ngokweqile noma ukushisa kwe-mold surface.Ukucindezela okwedlulele kokupholisha kanye nesikhathi sokupholisha yizimbangela eziyinhloko "zekhasi lewolintshi".
Isibonelo: ukupholisha isondo lokupholisha, ukushisa okukhiqizwa isondo lokupholisha kungabangela kalula "ikhasi lewolintshi".
Izinsimbi eziqinile zingakwazi ukumelana nokucindezela okukhulu kokupholisha, kuyilapho izinsimbi ezithambile zijwayele ukupholisha ngokweqile.Ucwaningo luye lwabonisa ukuthi isikhathi overpolish siyahlukahluka kuye ngobulukhuni impahla steel.
(3) Izinyathelo zokuqeda “ikhasi lewolintshi” le-workpiece
Uma kutholakala ukuthi ikhwalithi yangaphezulu ayiphucuziwe kahle, abantu abaningi bazokwandisa ukucindezela kokupholisha futhi bandise isikhathi sokupholisha, okuvame ukwenza ikhwalithi ephezulu ibe ngcono.umehluko.Lokhu kungalungiswa ngokusebenzisa:
1. Susa indawo enesici, usayizi wezinhlayiyana zokugaya kancane kancane kunangaphambili, sebenzisa inombolo yesihlabathi, bese ugaya futhi, amandla okupholisha aphansi kunesikhathi sokugcina.
2. Ukunciphisa ingcindezi kwenziwa ezingeni lokushisa elingaphansi kuka-25 ℃.Ngaphambi kokupholishwa, sebenzisa isihlabathi esihle ukuze ugaye kuze kube yilapho kutholakala umphumela owanelisayo, futhi ekugcineni ucindezele kancane bese upholisha.
(4) Isizathu sokwakheka “kokugqwala komgodi” phezu kwendawo yokusebenza ukuthi okunye ukungcola okungeyona okwensimbi ensimbi, ngokuvamile ama-oxide aqinile nama-brittle, akhishwa endaweni yensimbi phakathi nenqubo yokupholishwa, kwakheka i-micro. -imigodi noma ukugqwala kwemigodi.
holela "
Izici eziyinhloko ze "pitting" zimi kanje:
I-1) Ingcindezi yokupholisha inkulu kakhulu futhi isikhathi sokupholisha side kakhulu
I-2) Ukuhlanzeka kwensimbi akwanele, futhi okuqukethwe kokungcola okunzima kuphezulu.
3) Isikhunta sigqwalile.
4) Isikhumba esimnyama asisuswa
