Ngaphambi kokuthi amanye amakhasimende axoxisane nge-titanium alloy, futhi acabanga ukuthi ukucubungula i-titanium alloy kuyinkinga kakhulu.Manje, ozakwethu boMnyango Wezobuchwepheshe we-RSM bazokwabelana nawe ukuthi kungani sicabanga ukuthi i-titanium alloy yinto enzima ukuyicubungula?Ngenxa yokuntuleka kokuqonda okujulile kwendlela yokucubungula kanye nokwenzeka kwayo.
1. Izigigaba ezingokomzimba zokucubungula i-titanium
Amandla okusika we-titanium alloy aphakeme kancane nje kunalawo ensimbi enobunzima obufanayo, kodwa isimo somzimba sokucubungula i-titanium alloy siyinkimbinkimbi kakhulu kunaleyo yokucubungula insimbi, okwenza ukucubungula kwe-titanium alloy kubhekane nobunzima obukhulu.
I-thermal conductivity yama-alloys amaningi e-titanium iphansi kakhulu, i-1/7 kuphela yensimbi kanye ne-1/16 ye-aluminium.Ngakho-ke, ukushisa okukhiqizwa ohlelweni lokusika i-titanium alloy ngeke kudluliselwe ngokushesha ku-workpiece noma kuthathwe ama-chips, kodwa kuzogxilwa endaweni yokusika, futhi izinga lokushisa elikhiqizwayo lingaba phezulu njenge-1000 ℃ noma ngaphezulu, ukuze unqenqema lokusika lwethuluzi luguge ngokushesha, luqhekeke futhi lukhiqize izimila ze-chip accretion.Unqenqema oluguga ngokushesha lungaphinde lukhiqize ukushisa okwengeziwe endaweni yokusika, kunciphise kakhulu impilo yamathuluzi.
Izinga lokushisa eliphakeme elikhiqizwa inqubo yokusika liphinde libhubhise ubuqotho obungaphezulu bezingxenye ze-titanium ingxubevange, okuholela ekwehleni kokunemba kwejometri yezingxenye kanye nokuvela kwento eyenza umsebenzi ibe lukhuni enciphisa kakhulu amandla abo okukhathala.
I-elasticity ye-titanium alloy ingase ibe yinzuzo ekusebenzeni kwezingxenye, kodwa enqubweni yokusika, ukuguqulwa kwe-elastic ye-workpiece kuyisizathu esibalulekile sokudlidliza.Ingcindezi yokusika yenza i-workpiece "elastic" ihlukane nethuluzi futhi iphinde iboshwe, ukuze ukungqubuzana phakathi kwethuluzi nomsebenzi kukhulu kunomphumela wokusika.Inqubo yokungqubuzana iphinde ikhiqize ukushisa, okwandisa ukungahambi kahle kokushisa kwe-titanium alloys.
Le nkinga iba yimbi kakhulu uma kwenziwa izingxenye ezinezindonga ezincane noma eziyindandatho ezigogeke kalula.Akulula ukufaka izingxenye zengxube ye-titanium enezindonga ezincane zibe nokunemba kobukhulu obulindelekile.Njengoba i-workpiece material ixoshwa yithuluzi, ukuguqulwa kwendawo yodonga oluncane kudlule uhla olunwebekayo kanye nokuguqulwa kwepulasitiki kwenzeka, futhi amandla wezinto ezibonakalayo nobulukhuni endaweni yokusika kwanda kakhulu.Ngalesi sikhathi, ijubane lokusika elinqunywe ekuqaleni lizoba phezulu kakhulu, kubangele ukuguga kwamathuluzi abukhali.
"Ukushisa" "kuyicala" le-titanium alloy okunzima ukuyicubungula!
2. Amathiphu okucubungula okucubungula i-titanium alloy
Ngokwesisekelo sokuqonda indlela yokucubungula ye-titanium alloy, kuhlanganiswe nolwazi lwangaphambilini, ulwazi oluyinhloko lobuchwepheshe lokucubungula i-titanium alloy imi kanje:
(1) I-blade enejiyomethri ye-engeli eqondile isetshenziselwa ukunciphisa amandla okusika, ukushisa okusika kanye nokuguqulwa kwe-workpiece.
(2) Gcina ukondla okuzinzile ukuze ugweme ukuqina kwe-workpiece.Ithuluzi liyohlale lisesimweni sokuphakela ngesikhathi sokusika.Inani le-radial cutting ae ngesikhathi sokugaya lizoba ngu-30% werediyasi.
(3) Ukucindezela okuphezulu kanye noketshezi olukhulu lokusika ukugeleza kusetshenziselwa ukuqinisekisa ukuzinza okushisayo kwenqubo yomshini, futhi kugweme ukuwohloka kwendawo yokusebenza kanye nokulimala kwamathuluzi ngenxa yokushisa ngokweqile.
(4) Gcina i-blade ibukhali.Ithuluzi elingenalutho liyimbangela yokuqoqwa kokushisa nokugqoka, okuvele kuholele ekuhlulekeni kwamathuluzi.
(5) Ngangokunokwenzeka, kufanele icutshungulwe esimweni esithambile se-titanium alloy.Njengoba izinto ziba nzima kakhulu ukucubungula ngemva kokuqina, ukwelashwa kokushisa kuthuthukisa amandla wento futhi kwandisa ukuguga kwe-blade.
(6) Sebenzisa ithuluzi elikhulu elithi tip arc radius noma i-chamfer ukuze usike, futhi ufake ama-blade amaningi endaweni yokusika ngangokunokwenzeka.Lokhu kunganciphisa amandla okusika nokushisa endaweni ngayinye futhi kugweme ukulimala kwendawo.Lapho kugaywa ingxubevange ye-titanium, isivinini sokusika sinethonya elikhulu empilweni yamathuluzi vc, kulandelwa ukusika kwe-radial (ukujula kokugaya) ae.
3. Phatha izinkinga zokucubungula i-titanium kusuka ku-blade
Ukuguga kwensingo ngesikhathi sokucutshungulwa kwe-titanium alloy ukuguga kwendawo ngemuva nangaphambili eduze nokujula kokusika, okuvame ukubangelwa ungqimba oluqinile olushiywe ukucutshungulwa kwangaphambilini.Ukusabela kwamakhemikhali kanye nokusabalalisa kwethuluzi kanye nezinto zokusebenza endaweni yokushisa yokucubungula engaphezu kuka-800 ℃ futhi kungesinye sezizathu zokwakheka kokugqoka kwe-groove.Njengoba ama-molecule e-titanium omsebenzi enqwabelana phambi kwe-blade ngesikhathi sokucutshungulwa, "ashiselwe" ku-blade ngaphansi kwengcindezi ephezulu kanye nokushisa okuphezulu, okwenza isimila se-chip buildup.Lapho i-chip eyakhelwe ngaphakathi ihlutshiwe kusuka ku-blade, i-carbide ehlanganisiwe ye-blade iyasuswa.Ngakho-ke, ukucubungula i-titanium alloy kudinga izinto ezikhethekile ze-blade kanye namajamo wejometri.
