Intsimbi ephezulu yongezwa ngamanani ahlukeneyo ezinto ezixutywayo kwintsimbi.Emva kokunyanga ubushushu, izinto ezidibanisayo zomeleza isisombululo esiqinileyo, kwaye isakhiwo se-metallographic sininzi martensite.Inamandla amakhulu kunye nobunzima obuphezulu, kwaye ukuqina kwayo kwempembelelo kuphezulu kunentsimbi ye-45.Amandla okusika ngexesha lokusika kuya kuba ngama-25% -80% aphezulu ngaphezu kwamandla okusika i-45, ubushushu obuphezulu bokusika, kwaye ukuphulwa kwe-chip kunzima.Ke, kwimveliso yokwenyani, zisika njani iintsimbi eziphezulu?
1. Isixhobo
Ukusika kunye nokuphazamiseka, isixhobo siyafuneka ukuba sibe nokumelana nokutshatyalaliswa kwe-thermal.Ukongeza kwizixhobo zedayimane, zonke iintlobo zezixhobo zesixhobo zinokunqunyulwa.Xa ukhetha izixhobo zesixhobo, kufuneka zikhethwe ngokwemiqathango yokusika.
A. Isantya esiphezulu sentsimbi
Ukukhethwa kwesinyithi esinesantya esiphezulu sokusika intsimbi ephezulu kunye ne-ultra-high-amandla kufuneka kusekelwe kwiipropati, imilo, indlela yokucubungula kunye nokuqina kwenkqubo yenkqubo, kwaye kuqwalaselwe ngokubanzi ukuchasana nobushushu, ukunyanzeliswa kokugqoka kunye. ukuqina kwesixhobo sesixhobo.Xa inkqubo yenkqubo inokuqina okuphezulu kunye neprofayili yesixhobo ilula, i-tungsten-molybdenum-based, i-high-carbon low-vanadium ene-aluminium enesantya esiphezulu okanye i-tungsten-molybdenum-based based high-carbon low-vanadium high-cobalt high-cobalt isantya intsimbi ingasetyenziswa;phantsi kweemeko zokusika impembelelo, i-tungsten-molybdenum ingasetyenziswa.Intsimbi ephezulu ye-vanadium ephezulu.
B. Umgubo wesinyithi owenziwe ngesantya esiphezulu kunye neTin egqunywe ngesantya esiphezulu sentsimbi
Isinyithi se-powder high-speed steel singumgubo onesantya esiphezulu esicinezelwe ngokuthe ngqo kubushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye emva koko lufakwe kwimilo yesixhobo esifunekayo.Ilolwa emva kokucubungula kwaye inobunzima obuphezulu kunye nokumelana nokunxiba okuphezulu.Ifanelekile kwintsimbi ephezulu kunye ne-super.Ukusika intsimbi ephezulu.
C. Ikhabhide enesamente
I-carbide ene-cemented yisona sixhobo esisisiseko sokusika iintsimbi eziphezulu kunye ne-ultra-high-strength-strength.Ngokuqhelekileyo, ii-alloys eziqinileyo ezisebenza ngokuphezulu okanye ii-alloys eziqinileyo kufuneka zikhethwe.
D. Iimela zeCeramic
Ubunzima bayo kunye nokuchasana nokushisa kuphezulu kune-alloys enzima, ukuvumela ukusika isantya se-1-2 ngamaxesha aphezulu kune-carbides ene-cemented.Ekusikeni kwentsimbi ephezulu kunye ne-ultra-high-strength-strength, izixhobo ze-ceramic zisetyenziswa kakhulu kwi-sheet metal ukusebenza kunye nokulungiswa ngokuchanekileyo.
2. Ukunciphisa inani
Isantya sokusika ukuguqula intsimbi ephezulu kufuneka ibe yi-50% -70% ephantsi kunesantya sokusika isinyithi esiqhelekileyo.Ukuphakama kwamandla kunye nobunzima bezinto zokusebenza, isantya esisezantsi kufuneka sibe.Ukusika isantya sentsimbi ephezulu yokusika intsimbi ephezulu (3-10) m / min, isixhobo se-carbide (10-60) m / min, isixhobo se-ceramic yi (20-80) m / min, isixhobo se-CBN yi (40). —220) m/min.Ubunzulu bokusikwa kunye nokutya kuyafana nentsimbi yokuguqula ngokubanzi.
3. Indlela yokuqhawula i-chip
Ngenxa yokuqina okuphezulu kwentsimbi ephezulu, akulula ukuphula i-chip ngexesha lokujika, okuzisa ubunzima obukhulu ekusebenzeni kakuhle kokujika.Kuyimfuneko ukunikela ingqalelo ngakumbi kule nto ekuqhubeni.
