Ithonya Lokusika Ukushisa
Lapho kugaywa ama-alloys asekelwe ku-nickel, kukhiqizwa inani elikhulu lokushisa okusikayo. Ngakho-ke, lapho umshini, sebenzisa isipholile esanele sokucwilisa indawo yokusika, okulula ukuyifinyelela kubasiki bemishini yokugaya enobubanzi obuncane, kodwa kumathuluzi anobubanzi obukhulu (njengabasiki begayo bobuso), akunakwenzeka ukucwilisa ngokuphelele ngesikhathi sokusika, futhi isipholile singacishwa kuphela , kusetshenziswa ukugaya okomile.
Lapho i-milling cutter ingakwazi ukumbozwa yi-coolant, ukushisa kudluliselwa ngokushesha futhi kusukela ekufakeni, okuholela emifantwini eminingi emincane e-perpendicular kuya onqenqemeni lokusika, futhi imifantu iyanda kancane kancane, ekugcineni ibangele ukuphuka kwe-carbide esimende. Kwezinye izimo, i-milling cutter encane ingasetshenziswa, futhi akukho nto yokupholisa edingekayo ekwenzeni imishini. Uma ithuluzi lisika ngokujwayelekile futhi impilo yamathuluzi ithuthukiswa, kusho ukuthi ukugaya okomile okusebenzayo nakho kungenziwa.
Ngenxa yokuthi izingxenye zezimboni zezokwelapha kanye ne-aerospace ngokuvamile zenziwe ngama-alloys asekelwe ku-nickel, le nto ngokuvamile ihambisana nemibhalo yesitifiketi, lapho kunikezwa khona isakhiwo samakhemikhali salokhu okukhethekile, ukuze sazi lapho ukugaya kugaya. iyiphi impahla. Okufanele kunakwe ukuthi ungakhetha kanjani imingcele yokusika efanelekile nezindlela zokusika ngokusho kokwakheka kwezinto ezinjalo.
Njengoba kushiwo ngaphambili, izakhi ezimbili eziyinhloko zaleli qembu lezinsimbi ziyi-nickel ne-chromium. Uma isincibilikisi sensimbi silungisa inani lephesenti lensimbi ngayinye, izici zayo ezinjengokumelana nokugqwala, amandla, ubulukhuni, njll. ziyashintsha, kanjalo nokusebenza kwayo.
Ukudizayina ithuluzi lokusika izingcezu zokusebenza ezinzima noma eziqinile akunzima, kodwa ukuklama ithuluzi lengxubevange elisekelwe ku-nickel elenza kokubili akulula. Ungase ube nelakho igama lalezi zingxubevange, kodwa inqobo nje uma wazi ukwakheka kwazo futhi usebenzisa ithuluzi elifanele, ungakwazi ukugaya izinto ezifana ne-Corp20, Rene41, ne-Haynes242 ngaphandle kokushayisana.
