Ukugaya Ukucubungula
Ukucutshungulwa kokugaya kungokwama-machining wokuqeda (i-machining ihlukaniswe yaba imishini enzima, ukuqeda imishini, ukwelashwa kokushisa nezinye izindlela zokucubungula), ngenani elincane lokucubungula nokunemba okuphezulu. Isetshenziswa kabanzi embonini yokukhiqiza imishini. Ukushisa okuphathwe futhi kucinywe insimbi yensimbi yensimbi kanye nezingxenye zensimbi ezishisiwe nezicishiwe ngokuvamile zinenani elikhulu lemifantu ehleliwe njalo - imifantu yokugaya - ebusweni obuyi-perpendicular ngokuyisisekelo isiqondiso sokugaya ngesikhathi sokugaya. Akuthinti nje ukubonakala kwezingxenye, kodwa futhi kuthinta ngokuqondile ikhwalithi yezingxenye.
Isho inqubo yokusika yendawo yokusebenza enesondo lokugaya elijikelezayo elinesivinini esikhulu namanye amathuluzi abrasive. Ukugaya kusetshenziselwa ukucubungula indawo yangaphakathi nengaphandle yesilinda, indawo eyikholi kanye nezindiza zezinto zokusebenza ezahlukahlukene, kanye nezindawo ezikhethekile neziyinkimbinkimbi ezinjengama-Ge Ban chips, imicu, amagiya nama-splines.
Ngenxa yokuqina okuphezulu kwezinhlamvu ezihlabayo kanye nokuzilola kwamathuluzi abrasive, ukugaya kungasetshenziswa ukucubungula izinto ezihlukahlukene, okuhlanganisa insimbi eqinile, i-alloy steel alloy, i-alloy eqinile, ingilazi, i-ceramics, imabula nokunye okuqinile kwensimbi izinto ezingezona ezensimbi. Isivinini sokugaya sisho ijubane eliwumugqa wesondo lokugaya, ngokuvamile elingu-30~35 m/s. Uma idlula ku-45 m/s, ibizwa ngokuthi ukugaya ngesivinini esikhulu.
Ukugaya kuvame ukusetshenziselwa ukuqeda kancane nokuqeda, futhi ukunemba kungafinyelela ku-IT8~5 noma ngaphezulu. Ubulukhuni obungaphezulu buvame ukugaywa bufike ku-Ra1.25~0.16 μ m, ukunemba ukugaya ku-Ra0.16~0.04 μ m, ukugaya okunembe kakhulu ku-Ra0.04~0.01 μ m, kanye nokugaya kwesibuko ku-Ra0.01 μ m. Amandla athile okugaya (noma ukusetshenziswa kwamandla athile, okungukuthi, amandla asetshenziswa ukusika impahla yokusebenza ngevolumu yeyunithi ngayinye) makhulu kunalawo okusika okuvamile, futhi izinga lokususa insimbi lincane kunelo lokusika okuvamile.
Ngakho-ke, ngaphambi kokugaya, i-workpiece ivame ukususwa ngezinye izindlela zokusika ukuze kukhishwe i-machining allowance yezingxenye ezinkulu ze-Jiang Ali, kusale kuphela i-0.1 ~ 1mm noma ngaphansi kwesibonelelo sokugaya. Ngokuthuthukiswa kokugaya okuseqophelweni eliphezulu, okufana nokugaya okuphakelayo kwe-creep feed kanye nokugaya ngesivinini esikhulu, izingxenye zingagaywa ngokuqondile ezingenalutho. Ingase futhi isetshenziselwe ukwenza imishini enzima ngokugaya, njengokususa umgijimi kanye nesikhuphukeli sokusakazwa, ukukhanya kwe-forging kanye nesikhumba sezingothi zensimbi.
