Sezvatinoziva tese, kupfeka kwecemented carbide maturusi kwakakomba, izvo zvinokonzeresa kuomerwa mukukuya uye kukanganisa machining emhando yezvikamu chaizvo.Nekuda kwezvakasiyana zvekushandisa uye zvekucheka zvinhu, zvakajairwa kupfeka uye kubvaruka kwetungsten carbide maturusi ane anotevera mamiriro matatu:
1.Flank kupfeka
Kupfeka kwebanga rekumashure kunongoitika pachiso cheflank.Mushure mekupfeka, inoumba chidimbu chinoumba αo ≤0o, uye kureba kwayo VB kunoratidza huwandu hwekupfeka, izvo zvinowanzoitika kana kucheka brittle simbi kana epurasitiki simbi pazasi kucheka kumhanya uye kudiki kucheka ukobvu (αc <0.1mm).Panguva ino, kupesana kwemagetsi pachiso cheraki kuduku, uye kutonhora kwakaderera, saka kupfeka pachiso cheraki kwakakura.
2.CRater kupfeka
Rake face wear (Rake face wear) zvinoreva nzvimbo inopfekwa inoitika kunyanya pachiso cherake.Kazhinji, pakumhanya kwekucheka kwepamusoro uye kukora kukuru kwekucheka (αc> 0.5mm) kana uchicheka simbi dzepurasitiki, machipisi anobuda kubva pachiso cheraki, uye nekuda kwekukweshana, tembiricha yakakwira uye kudzvanywa kwakanyanya, gomba rinogadzika pachiso cheraki pedyo. iyo yekucheka.Huwandu hwekupfeka pachiso cheraki hunoratidzwa maererano nekudzika kwe crater KT.Munguva yekugadzirwa kwezvikamu zvakaringana, iyo crescent crater zvishoma nezvishoma inodzika uye inowedzera, uye inowedzera munzira yekucheka kumucheto, ichitotungamira kune chipping.
3.Rake uye flank zviso zvinopfekwa panguva imwe chete
Rake uye zviso zveflank zvinopfekwa panguva imwe chete zvinoreva kupfekwa kwezviso zverake neflank panguva imwe chete pamidziyo yecarbide mushure mekucheka.Iyi imhando yekupfeka inowanzoitika kana uchicheka masimbi epurasitiki panguva yepakati kucheka kumhanya uye kudyisa.
Yese yekucheka nguva yetungsten carbide chishandiso kubva pakutanga kwekukuya kusvika pakugadziriswa kwezvikamu zvakaringana kusvika huwandu hwekupfeka hwasvika pakupfeka hunonzi carbide chishandiso hupenyu, ndiko kuti, huwandu hwenguva yekucheka kwakachena pakati pezviviri kudzokorora. iyo carbide tool, iyo inoratidzwa ne "T".Kana miganho yekupfeka yakafanana, iyo yakareba hupenyu hwechigadzirwa checarbide, inononoka kupera kweiyo carbide chishandiso.
