Amathuluzi okusika i-carbide enosimende, ikakhulukazi amathuluzi e-carbide anosimende angafakwa ohlwini, ayimikhiqizo evelele kumathuluzi okugaya e-CNC. Kusukela ngawo-1980, ukuhlukahluka kwamathuluzi e-carbide anosimende aqinile nangena ohlwini noma ama-insert kuye kwanda kuzo zonke izizinda zamathuluzi okusika ahlukahlukene. Phakathi kwalawa, amathuluzi e-carbide anosimende angafakwa ohlwini ashintshe kusukela kumathuluzi alula okujika kanye nezicucu zokugaya ubuso ukuze afake uhla olubanzi lwamathuluzi okunemba, ayinkimbinkimbi, nawokwakha.
(1) Izinhlobo Zamathuluzi E-Carbide Ane-Cemented
Ngokusekelwe ekwakhekeni kwawo okuyinhloko kwamakhemikhali, ama-carbide aqinisiwe angahlukaniswa ngezigaba ezimbili eziyinhloko: ama-carbide aqinisiwe asekelwe ku-tungsten carbide kanye ne-carbide eqinisiwe esekelwe ku-titanium carbonitride (TiC(N)).
Ama-carbide aqiniswe nge-tungsten carbide ahlanganisa izinhlobo ezintathu:
I-Tungsten-cobalt (YG)
I-Tungsten-cobalt-titanium (YT)
Labo abane-carbide engavamile eyengeziwe (YW)
Uhlobo ngalunye lunezinzuzo nezinkinga zalo. Izingxenye eziyinhloko yi-tungsten carbide (WC), i-titanium carbide (TiC), i-tantalum carbide (TaC), i-niobium carbide (NbC), nezinye, kanti i-cobalt (Co) iyisihlanganisi sensimbi esisetshenziswa kakhulu.
Ama-carbide aqiniswe nge-titanium carbonitride akhiwe ngokuyinhloko yi-TiC, kanti ezinye izinhlobo zihlanganisa ama-carbide engeziwe noma ama-nitride. Ama-binder ensimbi asetshenziswa kakhulu yi-molybdenum (Mo) kanye ne-nickel (Ni).
I-International Organisation for Standardization (ISO) ihlukanisa ama-carbide aqinisiwe asetshenziselwa ukuhlukanisa izigaba ezintathu:
Ikilasi le-K (K10 kuya ku-K40): Lilingana nekilasi le-YG laseShayina (ikakhulukazi i-WC-Co).
Ikilasi le-P (P01 kuya ku-P50): Lilingana nekilasi le-YT laseShayina (ikakhulukazi i-WC-TiC-Co).
Ikilasi le-M (M10 kuya ku-M40): Lilingana nekilasi le-YW laseShayina (ikakhulukazi i-WC-TiC-TaC(NbC)-Co).
Ibanga ngalinye liboniswa ngezinombolo ezisukela ku-01 kuya ku-50, ezimele ububanzi bezinsimbi kusukela ebunzimeni obuphezulu kuya ebunzimeni obukhulu.
(2) Izici Zokusebenza Kwamathuluzi E-Carbide Ane-Cemented
① Ukuqina Okuphezulu
Amathuluzi e-carbide afakwe usimende akhiqizwa ngokusebenzisa i-powder metallurgy, ehlanganisa ama-carbide anobunzima obuphezulu kanye namaphuzu okuncibilika (okubizwa ngokuthi isigaba esiqinile) nama-binder ensimbi (okubizwa ngokuthi isigaba sokubopha). Ubulukhuni bawo busukela ku-89 kuya ku-93 HRA, budlula kakhulu obensimbi enesivinini esikhulu. Ku-540°C, ubulukhuni bawo buhlala buphakathi kuka-82 no-87 HRA, obufana nobunzima begumbi lokushisa kwensimbi enesivinini esikhulu (83–86 HRA). Ubulukhuni be-carbide efakwe usimende buyahlukahluka kuye ngohlobo, ubuningi, kanye nosayizi wezinhlamvu zama-carbide, kanye nokuqukethwe kwesigaba sokubopha sensimbi. Ngokuvamile, ubulukhuni buyehla njengoba okuqukethwe kwesigaba sensimbi esihlanganisiwe kukhuphuka. Kokuqukethwe okufanayo kwesigaba sokubopha, ama-alloy e-YT abonisa ubulukhuni obuphezulu kune-alloy e-YG, futhi ama-alloy ane-TaC noma i-NbC eyengeziwe anikeza ubulukhuni obuphezulu bokushisa okuphezulu.
② Amandla Nokuqina Kokugoba
Amandla okugoba kwama-carbide afakwe i-cemented asetshenziswa kakhulu aqala ku-900 kuya ku-1500 MPa. Okuqukethwe okuphezulu kwesigaba sokubopha insimbi kuphumela emandleni amakhulu okugoba. Uma okuqukethwe kwe-binder kuhambisana, ama-alloy e-YG (WC-Co) abonisa amandla aphezulu kune-alloy e-YT (WC-TiC-Co), amandla ehla njengoba okuqukethwe kwe-TiC kukhuphuka. I-carbide eyenziwe nge-cemented iyinto ebuthakathaka, futhi ukuqina kwayo komthelela ekushiseni kwegumbi kungama-1/30 kuya ku-1/8 kuphela kwensimbi yesivinini esikhulu.
(3) Ukusetshenziswa Kwamathuluzi E-Carbide Ahlanganisiwe Ane-Cemented
Ama-YG Alloys:Isetshenziswa kakhulu ekushiseni insimbi ephothiwe, izinsimbi ezingezona ezensimbi, kanye nezinto ezingezona ezensimbi. Ama-carbide afakwe ukhonkolo acwebezelayo (isb., YG3X, YG6X) anikeza ubulukhuni obuphezulu kanye nokumelana nokuguguleka kunezinhlobo eziphakathi nendawo ezinokuqukethwe okufanayo kwe-cobalt. Lawa afanele ukucubungula izinto ezikhethekile njengensimbi eqinile, insimbi engagqwali ye-austenitic, ama-alloy amelana nokushisa, ama-alloy e-titanium, ithusi eliqinile, kanye nezinto zokuvikela ezingagugi.
Ama-YT Alloys:Iphawuleka ngobulukhuni bayo obuphezulu, ukumelana nokushisa okuhle kakhulu, kanye nobunzima obuphezulu kanye namandla okucindezela emazingeni okushisa aphezulu uma kuqhathaniswa nama-alloy e-YG, kanye nokumelana okuhle kwe-oxidation. Uma amathuluzi edinga ukushisa okuphezulu kanye nokumelana nokuguguleka, kunconywa amazinga anokuqukethwe okuphezulu kwe-TiC. Ama-alloy e-YT alungele ukwenziwa kwezinto zepulasitiki njengensimbi kodwa awafaneleki ama-alloy e-titanium noma ama-alloy e-silicon-aluminium.
Ama-YW Alloys:Hlanganisa izakhiwo zama-alloy e-YG kanye ne-YT, okunikeza ukusebenza okuhle kakhulu. Ayakwazi ukushintshashintsha futhi angasetshenziswa ekushiseni insimbi, insimbi ephonswe, kanye nezinsimbi ezingezona i-ferrous. Ngokwandisa ngokufanele okuqukethwe yi-cobalt, ama-alloy e-YW angafinyelela amandla aphezulu, okwenza afaneleke ekushiseni okuqinile kanye nokusikwa okuphazamisekile kwezinto ezahlukahlukene ezinzima ukushiswa.
Kungani Ukhethe iChengduhuaxin Carbide?
I-Chengduhuaxin Carbide ivelele emakethe ngenxa yokuzibophezela kwayo ekhwalithini nasekusunguleni izinto ezintsha. Ama-blade abo ekhaphethi e-tungsten carbide kanye nama-blade e-tungsten carbide aklanyelwe ukusebenza kahle kakhulu, anikeza abasebenzisi amathuluzi ahlinzeka ngokusika okuhlanzekile nokunembile ngenkathi ebekezelela ubunzima bokusetshenziswa kakhulu kwezimboni. Ngokugxila ekuqineni nasekusebenzeni kahle, ama-blade e-Chengduhuaxin Carbide anikeza ikhambi elifanele izimboni ezidinga amathuluzi okusika anokwethenjelwa.

Imibuzo evamile yamakhasimende kanye nezimpendulo ze-Huaxin
Lokho kuncike enanini, ngokuvamile izinsuku ezi-5-14. Njengomkhiqizi wezinsika zezimboni, i-Huaxin Cement Carbide ihlela ukukhiqizwa ngama-oda kanye nezicelo zamakhasimende.
Ngokuvamile amasonto ama-3-6, uma ucela imimese yomshini eyenziwe ngokwezifiso noma ama-blade ezimboni angekho esitokweni ngesikhathi sokuthenga. Thola i-Sollex Purchase & Delivery Conditions lapha.
uma ucela imimese yomshini eyenziwe ngokwezifiso noma ama-blade ezimboni angekho esitokweni ngesikhathi sokuthenga. Thola Izimo Zokuthenga Nokulethwa ze-Sollexlapha.
Ngokuvamile i-T/T, i-Western Union...idiphozithi kuqala, Wonke ama-oda okuqala avela kumakhasimende amasha akhokhelwa kusengaphambili. Ama-oda engeziwe angakhokhwa nge-invoyisi...Xhumana nathiukwazi okwengeziwe
Yebo, xhumana nathi, imimese yezimboni iyatholakala ngezindlela ezahlukene, kufaka phakathi imimese enesitsha esiphezulu, imimese eyindilinga engezansi, imimese enezinyo ezigobile/ezinamazinyo, imimese ebhoboza nxazonke, imimese eqondile, imimese ye-guillotine, imimese ecijile, imimese ye-razor engunxande, kanye nemimese ye-trapezoidal.
Ukuze sikusize uthole i-blade engcono kakhulu, i-Huaxin Cement Carbide ingakunikeza ama-blade amaningana amasampula ongawahlola ekukhiqizweni. Ukuze usike futhi uguqule izinto eziguquguqukayo njengefilimu yepulasitiki, i-foil, i-vinyl, iphepha, nokunye, sinikeza ama-blade okuguqula kufaka phakathi ama-slitter blade anezikhala kanye nama-razor blade anezikhala ezintathu. Sithumelele umbuzo uma unentshisekelo kuma-blade omshini, futhi sizokunikeza isipho. Amasampula emimese eyenziwe ngokwezifiso awatholakali kodwa wamukelekile uku-oda inani elincane kakhulu le-oda.
Kunezindlela eziningi ezizokwandisa isikhathi eside kanye nokuphila kweshelufu kwemimese yakho yezimboni kanye nama-blade esitokweni. Xhumana nathi ukuze wazi ukuthi ukupakishwa okufanele kwemimese yomshini, izimo zokugcina, umswakama kanye nokushisa komoya, kanye nokwembozwa okwengeziwe kuzovikela imimese yakho futhi kugcine ukusebenza kwayo kokusika.
