1, kutengwa kwevatengesi veCNC blade vakashungurudzika nekupfeka kweCNC blades, abrasive kupfeka machipisi kana zvimwe zvidiki zvakaoma pamusoro peiyo workpiece (senge carbide, oxide, nezvimwewo) uye kusvibiswa (sejecha, oxide. , zvichingodaro), pamwe nekunamatira kweiyo chip tumor tsvina, zvichingodaro, chipfeko chemagetsi chinokonzerwa nemagrooves akavezwa pamusoro peCNC blade.Kune maturusi esimbi anomhanyisa ane yakaderera inotarisirwa kumhanya uye yakaderera yekucheka tembiricha (senge broach, kufa, tap, nezvimwewo), ndicho chinonyanya kukosha chikonzero chekupfeka.
2. Adhesive kupfeka inoumba kutsva kwepamusoro pekubata pasi pekumanikidza kwakanaka uye kucheka tembiricha pakati pechishandiso chekumashure cheCNC blade uye workpiece pamusoro uye pamberi pechishandiso chepamberi cheCNC blade nemachipisi.Kana iyo yekubata kumeso inosvika kune interatomic chinhambwe, iyo adsorption bond phenomenon inoitika.Iyo yekubatanidza poindi inochekwa zvishoma nezvishoma uye kubvarurwa kure neworkpiece kana machipisi, uye pamusoro peCNC blade inoburitsa inonamira kupfeka.Adhesive kupfeka ndechimwe chezvikonzero zvikuru zvekupfeka simende carbide kana uchicheka nepakati uye yakaderera kucheka kumhanya.
3, kupararira kunopfeka pakupisa kwakanyanya, kudzvanywa, CNC blade zvinhu uye workpiece zvinhu munzvimbo yakasimba yemamwe makemikari zvinhu mudiki diki kupararira, kureva, tungsten carbide Ti, w, Co uye zvimwe zvinhu zvakaita sesimbi diffusion, uye workpiece Fe, C uye zvimwe zvinhu kuCNC blade diffusion, zvichikonzera kuoma kwechishandiso chepamusoro, kuderera kwekuverenga kwakasimba, brittleness kuwedzera, kupfeka kwezvishandiso kuwedzera.Izvi zvinozivikanwa sekupfeka kwekupararira, uye kupfeka kwekupararira ndicho chimwe chezvikonzero zvikuru zvekupfekwa kwematurusi esimende ekucheka maturusi panguva yekutanga tembiricha (800 ″900 ° C).
4, kazhinji W, Co diffusion rate inokurumidza kupfuura Ti, Ta, saka tembiricha yekucheka mashandiro eYT class cemented carbide iri nani pane YG kirasi.Chikamu chekuchinja chinopfeka Paunenge uchicheka ne-high-speed simbi maturusi, kana tembiricha yekucheka ichipfuura tembiricha yekuchinja (550 ″600 ° C), iyo metallographic chimiro cheCNC blade ichachinja, kuitira kuti kuomarara kudere uye kupfeka kuwedzere. , saka chikamu chekuchinja kupfeka ndicho chimwe chezvikonzero zvikuru zvekupfekwa kwesimbi yakakwirira-yepamusoro CNC blade.Kupfeka Kemikari Pane imwe tembiricha, midhiya yakatenderedza nzvimbo yekucheka, senge mhepo, yekucheka mvura, nezvimwewo, inonamira kemikari nechokushandisa kugadzira mamwe makomba akasununguka uye asina kusimba.Makomponi aya ari nyore kutemwa uye abrasion yebasa kure, zvichikonzera CNC blade kupfeka.
