Amathuluzi okusika i-carbide enosimende, ikakhulukazi amathuluzi e-carbide enosimende, ayimikhiqizo ehamba phambili kumathuluzi womshini we-CNC. Kusukela ngeminyaka yawo-1980s, izinhlobonhlobo zawo womabili amathuluzi e-carbide enosimende aqinile futhi anenkomba noma okufakwayo kuye kwanda ezizindeni zamathuluzi okusika ahlukahlukene. Phakathi kwalokhu, amathuluzi e-carbide anosimende avela kumathuluzi alula okujika kanye nezisiki zokugaya ubuso ukuze afake izinhlobonhlobo zokunemba, eziyinkimbinkimbi, kanye namathuluzi okwakha.
(1) Izinhlobo Zamathuluzi E-Cemented Carbide
Ngokusekelwe ekubunjweni kwawo kwamakhemikhali ayinhloko, ama-carbide asimende angahlukaniswa abe izigaba ezimbili eziyinhloko: i-tungsten carbide-based cemented carbides kanye ne-titanium carbonitride (TiC(N))-based cemented carbide.
I-tungsten carbide-based cemented carbides ihlanganisa izinhlobo ezintathu:
I-Tungsten-cobalt (YG)
I-Tungsten-cobalt-titanium (YT)
Labo abane-carbides engeziwe engavamile (YW)
Uhlobo ngalunye lunezinzuzo zalo kanye nokubi. Izingxenye eziyinhloko yi-tungsten carbide (WC), i-titanium carbide (TiC), i-tantalum carbide (TaC), i-niobium carbide (NbC), nezinye, ezine-cobalt (Co) okuyi-binder yensimbi esetshenziswa kakhulu.
I-Titanium carbonitride-based cemented carbides akhiwe ngokuyinhloko nge-TiC, ngokuhlukile okunye okuhlanganisa ama-carbide engeziwe noma ama-nitride. Izibophezelo zensimbi ezivame ukusetshenziswa yi-molybdenum (Mo) kanye ne-nickel (Ni).
I-International Organisation for Standardization (ISO) ihlukanisa i-carbides enosimende esetshenziselwa ukusika izigaba ezintathu:
Ikilasi lika-K (K10 kuye ku-K40): Ilingana nekilasi le-YG lase-China (ikakhulukazi i-WC-Co).
Isigaba se-P (P01 ukuya ku-P50): Ilingana nekilasi le-YT lase-China (ikakhulukazi i-WC-TiC-Co).
I-M class (M10 ukuya ku-M40): Ilingana nesigaba se-YW sase-China (ikakhulukazi i-WC-TiC-TaC(NbC)-Co).
Ibanga ngalinye liboniswa izinombolo ezisuka ku-01 kuye ku-50, ezimele i-spectrum yama-alloys ukusuka kokuqina okuphezulu kuye kokuqina okukhulu.
(2) Izici Zokusebenza Zamathuluzi E-Cemented Carbide
① Ukuqina Okuphakeme
Amathuluzi e-carbide anosimende akhiqizwa nge-powder metallurgy, ehlanganisa i-carbides enobulukhuni obuphezulu kanye namaphuzu ancibilikayo (okubizwa ngokuthi isigaba esiqinile) nezibophezelo zensimbi (okubizwa ngokuthi isigaba sokubopha). Ubulukhuni bazo busuka ku-89 kuye ku-93 HRA, obudlula kude obensimbi enesivinini esikhulu. Ku-540°C, ubulukhuni bazo buhlala buphakathi kuka-82 no-87 HRA, uma buqhathaniswa nobulukhuni bezinga lokushisa kwegumbi lensimbi yesivinini esikhulu (83–86 HRA). Ukuqina kwe-carbide enosimende kuyahlukahluka kuye ngohlobo, ubuningi, nosayizi wokusanhlamvu we-carbides, kanye nokuqukethwe kwesigaba sokubopha insimbi. Ngokuvamile, ubulukhuni buyehla njengoba okuqukethwe kwesigaba sensimbi sokubopha kwanda. Kokuqukethwe kwesigaba sokubopha okufanayo, ama-alloy e-YT abonisa ubulukhuni obuphezulu kunama-alloys e-YG, nama-alloys ane-TaC eyengeziwe noma i-NbC anikeza ubulukhuni obuphakeme bezinga lokushisa eliphezulu.
② Amandla Okugoba Nokuqina
Amandla okugoba ama-carbides anosimende avame ukusetshenziswa asukela ku-900 kuye ku-1500 MPa. Okuqukethwe kwesigaba se-metal bonding ephakeme kubangela amandla amakhulu okugoba. Uma okuqukethwe kwe-binder kufana, ama-alloys e-YG (WC-Co) abonisa amandla aphezulu kune-YT (WC-TiC-Co) alloys, amandla ehla njengoba okuqukethwe kwe-TiC kukhula. I-carbide enosimende iyinto ephukayo, futhi ukuqina kwayo komthelela ekushiseni kwegumbi kungu-1/30 kuya ku-1/8 kuphela wensimbi enesivinini esikhulu.
(3) Izicelo ze-Common Cemented Carbide Tools
I-YG Alloys:Ikakhulukazi isetshenziselwa ukukhanda insimbi eyinsimbi, izinsimbi ezingezona ayoni, nezinto ezingezona ezensimbi. Ama-carbides anosimende anohlamvu oluhle (isb., i-YG3X, i-YG6X) anikeza ubulukhuni obuphakeme nokumelana nokugqoka kunezinhlobonhlobo ezinohlamvu olumaphakathi ezinokuqukethwe kwe-cobalt okufanayo. Lezi zilungele ukucubungula izinto ezikhethekile ezifana nensimbi eqinile, insimbi engagqwali ye-austenitic, ama-alloys angashisi, ama-titanium alloys, ithusi eliqinile, nezinto zokuvikela ukumelana nokugqoka.
I-YT Alloys:Okuphawuleka ngobulukhuni bazo obuphezulu, ukumelana nokushisa okuhle kakhulu, nobulukhuni obuphakeme namandla okucindezela emazingeni okushisa aphezulu uma kuqhathaniswa nama-alloys e-YG, kanye nokumelana ne-oxidation okuhle. Uma amathuluzi edinga ukushisa okuphezulu nokungagugi, amabanga anokuqukethwe okuphezulu kwe-TiC ayanconywa. Ama-alloys e-YT alungele ukwenza izinto zepulasitiki ezifana nensimbi kodwa awafanele ama-titanium alloys noma ama-silicon-aluminium alloys.
I-YW Alloys:Hlanganisa izakhiwo ze-YG ne-YT alloys, enikeza ukusebenza okuhle kakhulu sekukonke. Aguquguquka futhi angasetshenziselwa ukwenza insimbi, i-cast iron, nezinsimbi ezingenayo insimbi. Ngokwandisa ngokufanele okuqukethwe kwe-cobalt, ama-alloys e-YW angakwazi ukuzuza amandla aphezulu, awenze afaneleke umshini onzima kanye nokusikwa okuphazamisekile kwezinto ezihlukahlukene ezinzima emshinini.
Kungani Khetha i-Chengduhuaxin Carbide?
I-Chengduhuaxin Carbide igqama emakethe ngenxa yokuzibophezela kwayo kwikhwalithi nokusungula izinto ezintsha. Izindwani zabo ze-tungsten carbide carpet blades slotted blades ze-tungsten carbide zakhelwe ukusebenza okuphakeme, zihlinzeka abasebenzisi ngamathuluzi aletha ukusikeka okuhlanzekile, okunembayo kuyilapho emelana nobunzima bokusetshenziswa kwezimboni okunzima. Ngokugxila ekuqineni nasekusebenzeni kahle, ama-blade slotted we-Chengduhuaxin Carbide anikeza isixazululo esifanelekile sezimboni ezidinga amathuluzi okusika anokwethenjelwa.
I-CHENGDU HUAXIN CEMENTED CARBIDE CO., LTD bangabahlinzeki abaqeqeshiwe nabakhi beimikhiqizo ye-tungsten carbide,njenge-carbide faka imimese yokwenza izinkuni,i-carbideimimese eyindilingaokweizihlungi zikagwayi&zikagwayi ezisikayo,imimese eyindilinga ukusika amakhadibhodi ngothayela,izinsingo ezinezimbobo ezintathu/izindwani ezicijile yokupakisha, itheyiphu, ukusika ifilimu ezacile, ama-fiber cutter blades embonini yendwangu njll.

Ngekhwalithi enhle kakhulu namanani okuncintisana, isimo sethu sengqondo sokusebenza kanzima nokusabela kugunyazwe amakhasimende ethu. Futhi singathanda ukusungula ubudlelwano obusha bebhizinisi namakhasimende amasha.
Xhumana nathi namuhla futhi uzojabulela izinzuzo zekhwalithi enhle kanye nezinsizakalo ezivela emikhiqizweni yethu!
Imibuzo evamile yekhasimende nezimpendulo ze-Huaxin
Lokho kuncike enanini, ngokuvamile 5-14days. Njengomkhiqizi wezinsimbi zezimboni, i-Huaxin Cement Carbide ihlela ukukhiqizwa ngama-oda nezicelo zamakhasimende.
Ngokuvamile amaviki angu-3-6, uma ucela imimese yomshini eyenziwe ngokwezifiso noma izinsimbi zezimboni ezingekho esitokisini ngesikhathi sokuthenga. Thola I-Sollex Purchase & Delivery Conditions lapha.
uma ucela imimese yemishini eyenziwe ngokwezifiso noma izinsimbi zezimboni ezingekho esitokweni ngesikhathi sokuthenga. Thola I-Sollex Purchase & Delivery Conditionslapha.
Ngokuvamile i-T/T, i-Western Union...idiphozithi okokuqala, Wonke ama-oda okuqala avela kumakhasimende amasha akhokhwa kusengaphambili. Amanye ama-oda angakhokhwa nge-invoyisi...Xhumana nathiukwazi okwengeziwe
Yebo, xhumana nathi, Imimese Yezimboni itholakala ngezindlela ezihlukahlukene, okuhlanganisa isitsha esiphezulu, imimese eyindilinga engezansi, imimese ehlanganisiwe / enamazinyo, imimese eyisiyingi yokubhoboza, imimese eqondile, imimese ye-guillotine, imimese ecijile ecijile, ama-razor blade, nama-trapezoidal blades.
Ukukusiza ukuthi uthole i-blade ehamba phambili, i-Huaxin Cement Carbide ingakunikeza amasampula amasampula ambalwa ongawahlola ekukhiqizeni. Ngokusika nokuguqula izinto eziguquguqukayo njengefilimu yepulasitiki, i-foil, i-vinyl, iphepha, nezinye, sinikeza ama-blade aguqulayo afaka ama-slitter blades nama-razor anezikhala ezintathu. Sithumele umbuzo uma uthanda ama-blade emishini, futhi sizokunikeza okunikezwayo. Amasampula emimese eyenziwe ngokwezifiso awatholakali kodwa wamukelekile kakhulu uku-oda inani elincane le-oda.
Kunezindlela eziningi ezizokwandisa isikhathi eside nempilo yeshalofu yemimese nama-blade embonini yakho esitokweni. xhumana nathi ukuze wazi ukuthi ukupakishwa okufanele kwemimese yomshini, izimo zokugcina, umswakama kanye nokushisa komoya, kanye nezingubo ezengeziwe kuzovikela imimese yakho futhi kugcine ukusebenza kwazo kokusika.
