Kwiintsuku ezimbalwa ezidlulileyo, ikhadi lengxelo yophuhliso lweminyaka elishumi yoshishino lwelizwe lam kunye nolwazi lwabhengezwa: Ukususela ngo-2012 ukuya ku-2021, ixabiso elongezelelweyo loshishino lwemveliso liya kunyuka ukusuka kwi-16.98 yetriliyoni ye-yuan ukuya kwi-31.4 yetriliyoni ye-yuan, kunye nomlinganiselo wehlabathi. iza kunyuka ukusuka malunga ne-20% ukuya phantse kuma-30%.… Into nganye eneenkcukacha ezimangalisayo kunye nempumelelo ephawulwe ukuba ilizwe lam lingenise umtsi wembali ukusuka “kumandla okwenza izinto” ukuya “kumandla wokuvelisa”.
Amacandelo angundoqo ezixhobo eziphambili ngokuqhelekileyo kufuneka abe neempawu zobunzima bokukhanya, amandla aphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-corrosion, ukumelana nokunxiba, njl., kunye nezinto zemveli azikwazi ukuhlangabezana neemfuno.Ngophuhliso lwenzululwazi kunye nobuchwepheshe, izinto ezintsha ezifana ne-titanium alloys, i-nickel alloys, i-ceramics ephezulu yokusebenza, i-ceramic-reinforced metal matrix composites, kunye ne-fiber-reinforced composites ziyaqhubeka zivela.Nangona ezi mathiriyeli zinokuhlangabezana neemfuno zokusebenza zamacandelo angundoqo, ukuqhubekeka okunzima kakhulu kuye kwaba yingxaki eqhelekileyo, kwaye ikwayingxaki amaziko ophando lwenzululwazi kwihlabathi jikelele ebezama ngako konke okusemandleni awo ukuyisombulula.
Njengobuchwephesha obutsha bokusombulula le ngxaki, i-ultra-high-speed machining inethemba elikhulu kushishino lokuvelisa.I-teknoloji ebizwa ngokuba yi-ultra-high-speed machining technology ibhekisela kwi-teknoloji entsha ye-machining etshintsha ukunyanzeliswa kwezinto ngokunyusa isantya somatshini, kunye nokuphucula izinga lokususa izinto, ukuchaneka komatshini kunye nomgangatho womatshini.Isantya somatshini se-Ultra-high-speed singaphezulu kwamaxesha e-10 ngokukhawuleza kunomatshini wemveli, kwaye izinto eziphathekayo zisuswa ngaphambi kokuba zikhubazeke ngexesha lenkqubo ye-ultra-high-speed machining.Iqela lophando leYunivesithi yaseMzantsi yeSayensi kunye neThekhnoloji yafumanisa ukuba xa isantya sokucubungula sifikelela kwiikhilomitha ze-700 ngeyure, impawu "ezinzima-kwinkqubo" yezinto eziphathekayo iyanyamalala, kwaye ukulungiswa kwezinto eziphathekayo "kujika kunzima ukuba kube lula".
I-Titanium alloy yinto eqhelekileyo "enzima-kumatshini", eyaziwa ngokuba yi "chewing gum" kwizinto eziphathekayo.Ngexesha lokucutshungulwa, kuya "kunamathela kwimela" njengokuhlafuna itshungama emazinyweni, yenze "i-tumor eqhekezayo".Nangona kunjalo, xa isantya sokucubungula sinyuswa kwixabiso elibalulekileyo, i-titanium alloy ayiyi kuphinda "inamathele kwi-mela", kwaye akuyi kubakho iingxaki eziqhelekileyo kwiinkqubo zendabuko ezifana ne "workpiece burn".Ukongezelela, umonakalo wokucubungula uya kunyanzeliswa kunye nokunyuka kwesantya sokucubungula, ukwenza umphumo "wesikhumba esonakele".Itekhnoloji ye-Ultra-high-speed machining ayinakuphucula kuphela ukusebenza kakuhle komatshini, kodwa iphucula umgangatho womatshini kunye nokuchaneka.Ngokusekwe kwiithiyori ze-ultra-high-speed machining ezifana ne "imbrittlement material" kunye "nomonakalo eluswini", okoko nje isantya esibalulekileyo somatshini sifikelelwe, iimpawu ezinzima zomatshini ziya kutshabalala, kunye nokulungiswa kwezinto. kuya kuba lula njengokuthi "ukupheka iqhekeza lenyama ukusombulula inkomo".
Okwangoku, amandla amakhulu okusebenzisa itekhnoloji ye-Ultra-high-speed machining iye yatsala ingqalelo ebanzi.IZiko loBunjineli beMveliso yeHlabathi lithatha itekhnoloji ye-Ultra-high-speed-high njengeyona ndlela yophando lwenkulungwane yama-21, kwaye iJapan Advanced Technology Research Association nayo ibeka itekhnoloji ye-Ultra-high-high-high-speed machining technology njengenye yeetekhnoloji ezintlanu zokuvelisa.
Okwangoku, izinto ezintsha zihlala zivela, kwaye itekhnoloji ye-Ultra-high-speed machining kulindeleke ukuba isombulule ngokupheleleyo iingxaki zokusetyenzwa kunye nokuzisa uguquko kumgangatho ophezulu kunye nokusebenza kakuhle kwezixhobo "ezinzima ukuya kumatshini", ngelixa i-ultra-high. -izixhobo zoomatshini besantya ezaziwa ngokuba "ngoomatshini boomama bemizi mveliso" kulindeleke ukuba zibe yimpumelelo "Izinto ezintsonkothileyo zokuqhubela phambili" sisixhobo esinamandla sokujongana nobunzima.Kwixesha elizayo, i-ecology yamashishini amaninzi nayo iya kutshintsha ngenxa yoko, kwaye imimandla emitsha yokukhula ngokukhawuleza iya kuvela, ngaloo ndlela itshintsha imodeli yeshishini ekhoyo kunye nokukhuthaza ukuphuculwa kweshishini lemveliso.
