Babban dalilin shigar carbide lalacewa

1, siyan 'yan kasuwa na ruwa na CNC sun damu da lalacewa ta ruwan wukake na CNC, kwakwalwan gogewa mai lalacewa ko wasu ƙananan maki a saman kayan aikin (kamar carbide, oxide, da sauransu) da ƙazanta (kamar yashi, oxide). , da dai sauransu), da kuma manne da tarkacen ƙwayar cuta, da dai sauransu, lalacewa ta injina da aka sassaƙa a saman ruwan CNC.Don kayan aikin ƙarfe masu sauri tare da ƙarancin saurin sa ran da ƙarancin zafin jiki (kamar broach, mutu, famfo, da sauransu), shine mafi mahimmancin dalilin lalacewa.

2. M lalacewa Forms sabo ne surface lamba karkashin tabbatacce matsa lamba da kuma yankan zafin jiki tsakanin baya kayan aiki fuskar CNC ruwa da workpiece surface da gaban kayan aiki fuskar CNC ruwa da kwakwalwan kwamfuta.Lokacin da farfajiyar lamba ta kai nisan interatomic, abin al'ajabi na haɗin kai yana faruwa.A hankali an yanke ma'anar haɗin gwiwa da kayan aiki ko kwakwalwan kwamfuta, kuma saman ruwan CNC zai haifar da lalacewa.Lalacewar mannewa yana ɗaya daga cikin manyan dalilai na lalacewa na simintin carbide lokacin yankewa a matsakaici da ƙarancin yankewa.

3, yaduwa lalacewa a high zafin jiki, high matsa lamba, CNC ruwa abu da workpiece abu a cikin m jihar na wasu sinadaran abubuwa a cikin kananan juna yaduwa, wato, tungsten carbide Ti, w, Co da sauran abubuwa kamar karfe watsawa, da kuma workpiece Fe, C da sauran abubuwa zuwa CNC ruwa yaduwa, sakamakon taurin saman kayan aiki, karfi karatu ƙi, brittleness karuwa, kayan aiki lalacewa intensification.Wannan ana kiransa da lalacewa mai yaduwa, kuma lalacewa yana ɗaya daga cikin manyan dalilan sa kayan aikin yankan siminti a farkon yanayin zafi (800″ 900°C).

4, gabaɗaya W, Yawan watsawar Co ya fi Ti, Ta, don haka babban aikin yankan zafin jiki na YT cemented carbide ya fi aji YG.Canjin canjin lokaci Lokacin yankan tare da kayan aikin ƙarfe masu sauri, lokacin da yankan zafin jiki ya wuce yanayin canjin lokaci (550 ″ 600 ° C), tsarin ƙarfe na ƙarfe na CNC zai canza, ta yadda taurin zai ragu kuma lalacewa zai haɓaka. , Don haka lalacewa canjin lokaci yana daya daga cikin manyan dalilai na lalacewa na babban ƙarfin ƙarfe na CNC mai sauri.Ciwon sinadari A wani yanayin zafi, kafofin watsa labarai da ke kusa da yankin yanke, kamar iska, yanke ruwa, da sauransu, suna amsawa da sinadarai tare da kayan aikin don samar da wasu sassauƙan mahadi.Wadannan mahadi suna da sauƙin yankewa da kawar da aikin aiki, wanda ke haifar da lalacewa ta CNC.
