Into yokuqala okufanele sikhulume ngayo yinto ebonakalayo yokucubungula i-titanium alloy. Nakuba amandla okusika we-titanium alloy ephakeme kancane kunensimbi enobunzima obufanayo, isimo somzimba sokucubungula i-titanium alloy siyinkimbinkimbi kakhulu kunaleyo yokucubungula insimbi, okwenza ubunzima bokucubungula i-titanium alloy bunyuke.
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 ngesikhathi sokusika ama-alloys e-titanium ngeke kudluliselwe ngokushesha ku-workpiece noma kuthathwe ama-chips, kodwa kuzoqoqa endaweni yokusika, futhi izinga lokushisa elikhiqizwayo lingaba phezulu ku-1 000 ° C noma ngaphezulu. , okuzokwenza ukuthi umkhawulo wokusika wethuluzi ugqoke ngokushesha, uhlakaze futhi uqhekeke. Ukwakheka konqenqema olwakhiwe, ukubukeka okusheshayo konqenqema olugugile, nakho kukhiqiza ukushisa okwengeziwe endaweni yokusika, kunciphise ngokwengeziwe impilo yethuluzi.
Izinga lokushisa eliphakeme elikhiqizwa ngesikhathi sokusika liphinde libhubhise ubuqotho obungaphezulu bezingxenye ze-titanium alloy, okuholela ekwehleni kokunemba kwejometri yezingxenye kanye nesenzakalo esinzima somsebenzi esinciphisa kakhulu amandla abo okukhathala.
I-elasticity ye-titanium alloys ingase ibe yinzuzo ekusebenzeni kwezingxenye, kodwa phakathi nenqubo yokusika, ukuguqulwa kwe-elastic kwe-workpiece kuyimbangela ebalulekile yokudlidliza. Ingcindezi yokusika idala ukuthi i-workpiece "elastic" isuke kude nethuluzi bese igxuma ukuze ukungqubuzana phakathi kwethuluzi nomsebenzi kube kukhulu kunesenzo sokusika. Inqubo yokungqubuzana iphinde ikhiqize ukushisa, ibhebhethekise inkinga yokungahambi kahle kokushisisa kwama-alloys e-titanium.
Le nkinga ibucayi nakakhulu lapho kucutshungulwa izingxenye ezinezindonga ezincane noma eziyindandatho ezigogeke kalula. Akuwona umsebenzi olula ukucubungula izingxenye ezinezindonga ezincane ze-titanium alloy zibe nokunemba kobukhulu obulindelwe. Ngoba lapho i-workpiece material ixoshwa yithuluzi, ukuguqulwa kwendawo yodonga oluncane kudlule uhla olunwebekayo kanye nokuguqulwa kwepulasitiki kwenzeka, futhi amandla wezinto ezibonakalayo nobulukhuni bephoyinti lokusika kukhula kakhulu. Kuleli qophelo, ukwenza imishini ngesivinini esinqunyiwe ngaphambili sokusika kuba phezulu kakhulu, okuholela ekugugeni kwamathuluzi abukhali. Kungashiwo ukuthi "ukushisa" "yimbangela yezimpande" eyenza kube nzima ukucubungula ama-alloys e-titanium.
Njengomholi embonini yamathuluzi okusika, u-Sandvik Coromant uhlanganise ngokucophelela ulwazi lwenqubo yokucubungula ama-alloys e-titanium futhi wabelwa nayo yonke imboni. U-Sandvik Coromant uthe ngesisekelo sokuqonda indlela yokucutshungulwa kwe-titanium alloys kanye nokwengeza ulwazi oludlule, ulwazi lwenqubo eyinhloko yokucubungula ama-alloys e-titanium kanje:
(1) Ukufakwa okunejiyomethri eqondile kusetshenziselwa ukunciphisa amandla okusika, ukushisa okusika kanye nokuguqulwa kwe-workpiece.
(2) Gcina okuphakelayo okungaguquki ukuze ugweme ukuqina kwe-workpiece, ithuluzi kufanele lihlale lisesimweni sokuphakela ngesikhathi sokusika, futhi inani le-radial cutting ae kufanele libe ngu-30% we-radius ngesikhathi sokugaya.
(3) Uketshezi lokusika olunomfutho ophezulu kanye nokugeleza okukhulu lusetshenziselwa ukuqinisekisa ukuzinza okushisayo kwenqubo yomshini futhi kuvimbele ukuwohloka kwendawo yokusebenzela kanye nokulimala kwamathuluzi ngenxa yokushisa ngokweqile.
(4) Gcina unqenqema lwe-blade lubukhali, amathuluzi abuthuntu ayimbangela yokwakheka kokushisa nokuguga, okungaholela kalula ekuhlulekeni kwamathuluzi.
(5) Ukucutshungulwa esimweni esithambile kakhulu se-titanium alloy ngangokunokwenzeka, ngoba impahla iba nzima kakhulu umshini ngemva kokuqina, futhi ukwelashwa kokushisa kwandisa amandla wento futhi kwandisa ukuguga kokufakwayo.
(6) Sebenzisa indawo enkulu yekhala noma i-chamfer ukuze usike, futhi ubeke imiphetho yokusika eminingi ngangokunokwenzeka ekusikeni. Lokhu kunciphisa amandla okusika nokushisa kuzo zonke izindawo futhi kuvimbela ukuphuka kwendawo. Lapho kugaywa ama-alloys e-titanium, phakathi kwemingcele yokusika, isivinini sokusika sinethonya elikhulu empilweni yamathuluzi vc, kulandelwa inani lokusika kwe-radial (ukujula kokugaya) ae.
