Izinto ezisetshenziswayo zamathuluzi zokusika zibe neminyaka engaphezu kwe-100 yomlando wentuthuko kusuka ku-carbon yethuluzi lensimbi ku-high-speed ithuluzi lensimbi ephezulu,Carbide ethosiwe, Ithuluzi le-Ceramicna-Izinto ze-Superhard Tool. Engxenyeni yesibili yekhulu le-18, impahla yasekuqaleni yensimbi yayiyinsimbi yamathuluzi e-carbon. Ngoba ngaleso sikhathi kwakusetshenziswa njengezinto ezinzima kunazo zonke ezingafakwa kumathuluzi wokusika. Kodwa-ke, ngenxa yokushisa kwayo okuvimbela ukushisa okuphansi kakhulu (ngaphansi kwama-200 ° C), amathuluzi e-Carbon anokungemthetho ukuthi asheshe futhi athule ngokuphelele ngenxa yokusika isivinini lapho usika isivinini esikhulu, futhi uhla lokusika lulinganiselwe. Ngakho-ke, sibheke phambili ezintweni zethuluzi ezingasikwa ngejubane eliphezulu. Okuqukethwe okuvelayo ukubonisa lokhu kulindelwe kuyinsimbi ephezulu.
Insimbi esheshayo ephezulu, eyaziwa nangokuthi i-Front Steel, yathuthukiswa ososayensi baseMelika ngonyaka we-1898. Akuyona kangako ukuthi iqukethe ikhabhoni encane kunensimbi yamathuluzi e-carbon, kepha iTungstern ingeziwe. Ngenxa yeqhaza le-carbide eliqinile le-tungsten, ubulukhuni balo abuncishiswa ngaphansi kwezimo zokushisa eziphakeme, futhi ngoba lingasikwa ngejubane elikhulu kakhulu kunejubane lokusika lensimbi yensimbi yekhabhoni, igama eliphakeme. Kusukela ngo-1900 ~ -1920, insimbi enesivinini esikhulu nge-vagadium ne-cobobalt yaqhamuka, futhi ukumelana kwawo kokushisa kwandiswa kuya ku-500 ~ 600 ° C. Isivinini sokusika sokusika insimbi efinyelela kuma-30 ~ 40m / amaminithi, anda cishe amahlandla ama-6. Kusukela lapho, ngokuthula kwezinto zayo ezakhiwe, zenziwe ama-speent aphezulu wensimbi. Kusasetshenziswa kabanzi kuze kube manje. Ukuvela kwensimbi enesivinini esiphakeme kubangele a
Ukuguqulwa kokusika ukucubungula, kuthuthukisa kakhulu umkhiqizo wokusika insimbi, futhi kudinga ushintsho oluphelele esakhiweni sethuluzi lomshini lokuzivumelanisa nezidingo zokusebenza ezintsha zamathuluzi. Ukuvela kanye nokuthuthuka okuqhubekayo kwamathuluzi omshini omusha, kuye kwaholela ekuthuthukisweni kwezinto zokwakha amathuluzi angcono, futhi amathuluzi avuswe futhi athuthukiswa. Ngaphansi kwezimo ezintsha zobuchwepheshe bokukhiqiza, amathuluzi ensimbi anesivinini esiphakeme nawo anenkinga yokunciphisa ukuqina kwethuluzi ngenxa yokusika ukushisa lapho usika ngejubane elikhulu. Lapho isivinini sokusika sifinyelela ku-700 ° C, insimbi esheshayo
Ithiphu ishubile, futhi ngesivinini sokusika ngaphezulu kwaleli nani, akunakwenzeka ngokuphelele ukusika. Ngenxa yalokhu, izinto ze-Carbide Tool ezigcina ubulukhuni obanele ngaphansi kwezimo zokushisa eziphakeme kunalokho okungenhla kuqhamuke futhi kunganqunywa emazingeni okushisa aphezulu.
Izinto ezithambile zingagawulwa ngezinto ezinzima, futhi ukuze usike izinto ezinzima, kuyadingeka ukusebenzisa izinto ezinzima kakhulu kunangaphambili. Into enzima kunazo zonke emhlabeni okwamanje yidayimane. Yize amadayimane lemvelo sekusele isikhathi eside emvelweni, futhi anomlando omude wokuwasebenzisa njengamathuluzi okusika, amadayimane okwenziwa nawo ahlanganiswe ngempumelelo ekuqaleni kweminyaka engama-50 yama-DIAMOMS enza kabanziIzinto zokusika zezimboni zokusikakuseyindaba yamashumi eminyaka yamuva.
Ngakolunye uhlangothi, ngokuthuthukiswa kobuchwepheshe besikhala sanamuhla nobuchwepheshe be-aerospace, ukusetshenziswa kwezinto zesimanje zobunjiniyela kuya ngokuya ziningi, yize insimbi enesivinini esithuthukile, i-carbide evundisiwe, kanyeIzinto ze-Teramic Ithuluzi ElishaEkugayeni kwemisebenzi yokusebenza kwendabuko, ukusika isivinini nokukhiqizwa okukhiqizwayo okuphindwe kabili noma izikhathi eziningi zanda, kodwa ukuqina kwamathuluzi nokuqina kunzima ukucubungula, kwesinye isikhathi kunzima ukucubungula, isidingo sokusebenzisa izinto zamathuluzi ezibukhali.
Ngakolunye uhlangothi, ngokuthuthuka okusheshayo kwesimanjeUkukhiqiza imishiniFuthi ukucubungula imboni, ukusetshenziswa okubanzi kwamathuluzi omshini othomathikhi, izikhungo zamanani we-computer (CNC) zemishini, kanye norkshops angahlelwanga emishini, ukuze kuthuthukiswe ukucubungula ukunemba, futhi kuthuthukiswe ukucubungula isikhathi, izidingo eziningi eziphuthumayo zenziwa ukuba zibe nezinto eziqinile nezizinzile zamathuluzi. Kulokhu, amathuluzi edayimane athuthukise ngokushesha, futhi ngasikhathi sinye, ukuthuthukiswa kweIzinto ze-Diamond Toolkubuye kukhuthazwe kakhulu.
Izinto ze-Diamond ToolIba nochungechunge lwezakhiwo ezinhle kakhulu, ngokunemba okuphezulu kokunemba, isivinini sokusika ngokushesha nempilo yenkonzo ende. Isibonelo, ukusetshenziswa kwe-Compax (i-Polycrystalline Diamond Composite Sheet) Amathuluzi angaqinisekisa ukucutshungulwa kwamashumi ezinkulungwane zama-Silicon Aluminium Alloy Piston Piston Ring Ring izingxenye namathiphu abo amathuluzi akushintshisi; Imishini yokufaka izindiza i-aluminium spars ene-commax enkulu cutter cuteters cutter angafinyelela isivinini sokusika esifinyelela ku-3660m / min; Lokhu akunakuqhathaniswa kumathuluzi we-carbide.
Hhayi lokho kuphela, ukusetshenziswa kweIzinto ze-Diamond ToolFuthi ingakhulisa inkambu yokucubungula futhi iguqule ubuchwepheshe bokucubungula kwendabuko. Esikhathini esedlule, ukucubungula isibuko kungasebenzisa kuphela inqubo yokugaya nokuphamba, kepha manje hhayi kuphela amathuluzi wedayimane lemvelo elilodwa, kodwa nakwezinye izimo kungasetshenziswa futhi amathuluzi ahlanganisiwe we-PDC super-hard-hard-hard composite wokunciphisa okungcono kakhulu, ukufeza ukuguquka esikhundleni sokugaya. NgokusebenzisaAmathuluzi amakhulu anzima, eminye imiqondo emisha ivele emkhakheni wemishini, njengokusetshenziswa kwamathuluzi we-PDC, ijubane lokuguqula elimkhawulo alisekho ithuluzi kodwa ithuluzi lomshini, futhi lapho ijubane lokujika lidlula ijubane elithile, i-workpiece nethuluzi alishisi. Imiphumela yale miqondo ebabazekayo iyi-scound futhi inikezela ngamathemba angenamkhawulo embonini yanamuhla yemishini.
