Sezvo isu tese tinoziva, kupfeka kwemidziyo yemasimichi kwakakomba, uko kuchakonzera kuomesa mukukuya kukuru uye kukanganisa maitiro emachinda ezvikamu zvakanyanyisa. Nekuda kwezvinhu zvakasiyana zvekushandisa uye kucheka zvinhu, iyo yakajairika yekupfeka uye misodzi ye tungsten midziyo yezvishandiso zvine matatu anotevera:
1.Flank Pfeka
Shure banga pfeka kupfeka chete kunoitika pachiso chemwedzi. Mushure mekupfeka, inoumba chikamu chinoumba quo ≤0O, uye iyo inowanzoitika kana ichiwanzoitika kana ichicheka mitezo yakaderera yekucheka uye αc <0.1mm). Panguva ino, kupokana kwechisimba pane chinhu chidiki chidiki, uye tembiricha yakaderera, saka kupfeka pachiso chakakura.
2.Ckupfeka kupfeka
Rake kumeso kupfeka kunoreva nzvimbo yekupfeka inowanzoitika pane zvakatarisana kumeso. Kazhinji, pakakwirira yekucheka kumhanya uye αc> 0.5mm) kana kucheka mitezo yemapurasitiki. Iyo huwandu hwekupfeka pane iyo yakatsemurwa kumeso inoratidzwa maererano nekanyadza kudzika kt. Munguva yemachinji ezvikamu zvakanyanyisa, crescent crescer inowedzera zvishoma nezvishoma uye inowedzera, uye inowedzera munzira yekucheka, ichitotungamira kuchipukuta.
3.Kutuka uye flank kumeso kwakapfekwa panguva imwe chete
Iyo yakatsva uye flank zviso zvinopfekwa panguva imwe chete Inoreva kupfeka panguva imwe chete yekupfeka uye flank zviso pamidziyo yemabhonzo mushure mekucheka. Iyi ndiyo nzira yekupfeka inowanzoitika kana ichicheka mapurasitiki metals kumativi ekucheka nepakati nekudya.
Nguva yakakwana yekucheka yeTungsten Carbide kubva pakutanga kwekusvika kwekusvika kwekushayiwa kwechikepe chekusvina Kana iyo kupfeka miganhu yakafanana, kureba hupenyu hwechishandiso chebhokisi, chinononoka kupfeka chechishandiso chebhokisi.
