I-CBN iqhudelana ne-PCD: Impi Yamathuluzi Okusika I-Superhard - Ukugxumela Okujulile Ekukhiqizeni nasekusebenzeni
CBN (Cubic Boron Nitride) CNC Cutting Amathuluzi
I-CBN, noma i-Cubic Boron Nitride, iyinto yokwenziwa eyaziwa ngobulukhuni bayo obedlulele nokuqina. Kungokwesibili kuphela kwedayimane ngokuphathelene nobulukhuni, okwenza kube yimpahla efanelekile yokusika amathuluzi asetshenziswa ekukhiqizeni okuphezulu kokusebenza. Amathuluzi okusika e-CBN ajwayele ukusetshenziselwa ukwenza izinsimbi eziqinile, izinsimbi ezisansimbi, nezinye izinto eziqinile okunzima ukuzicubungula ngamathuluzi okusika ajwayelekile.
Inqubo Yokukhiqiza Yamathuluzi e-CBN:
Ukukhiqizwa kwamathuluzi okusika e-CBN ngokuvamile kuhilela ukuhlanganiswa kwe-boron nitride (BN) ngaphansi kwengcindezi ephezulu kanye nokushisa okuphezulu. Inqubo iqala nge-boron powder kanye negesi ye-nitrogen, engaphansi kwezimo ezimbi kakhulu (ngaphezu kuka-1500 ° C) ukuze zakhe amakristalu e-cubic boron nitride (c-BN). Lawa makristalu abe esehlanganiswa nezinto ze-matrix, ngokuvamile i-cobalt binder, ukuze kwakhiwe into yokusika noma ithuluzi. Le nhlanganisela ihlinzeka ngethuluzi le-CBN ngobulukhuni bayo obumangalisayo nokumelana nokugqoka.
Ukufakwa kwe-CBN kungakhiqizwa ngamajamo nosayizi abahlukahlukene, kuye ngezidingo ezithile zomshini. Ithuluzi lokugcina livame ukucwiliswa, ligaywe, futhi limbozwe ukuze lithuthukise ukusebenza kwalo nokuqedwa kwendawo. Ikhono lethuluzi lokugcina imiphetho ebukhali emazingeni okushisa aphezulu likwenza kube ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezisindayo ezimbonini ezifana ne-aerospace, ezezimoto, nokukhiqiza amathuluzi.
PCD (Polycrystalline Diamond) CNC Cutting Amathuluzi
I-PCD, noma i-Polycrystalline Diamond, iwumsebenzi owenziwe ngokuhlanganisa amakristalu edayimane amahle ngaphansi kwengcindezi ephezulu nezinga lokushisa, okuholela ekubeni kube yinto eqinile, eqinile yokusika ithuluzi. Amathuluzi e-PCD aziwa ngokungezwani kwawo nokugqokwa okukhethekile, ikakhulukazi uma kwenziwa izinsimbi ezingenayo insimbi njenge-aluminium, ithusi, nethusi, kanye nezinto eziyinhlanganisela.
Inqubo Yokukhiqiza Yamathuluzi e-PCD:
Ukukhiqizwa kwamathuluzi e-PCD kuqala ngokudalwa kwezimpushana zedayimane ezinhle, ezihlanganiswe ne-binder yensimbi, ngokuvamile i-cobalt noma ezinye izimpushana zensimbi. Le ngxube ibe isifakwa ngaphansi kwezinga lokushisa eliphezulu, inqubo yokucindezela okukhulu eyaziwa ngokuthi "i-sintering" emshinini wokunyathelisa okhethekile. Phakathi nale nqubo, amakristalu edayimane ahlangana ndawonye, akha isakhiwo esiminyene, se-polycrystalline.
Amathuluzi e-PCD ngokuvamile akhiqizwa ngezindlela ezimbili eziyinhloko: i-monolithic ne-brazed. Ngendlela ye-monolithic, ithuluzi lonke lenziwe kusuka ku-PCD, kuyilapho ngendlela ye-brazed, ungqimba oluncane lwe-PCD lufakwe ku-carbide substrate. Ngemuva kokucwiliswa, amathuluzi e-PCD ayagaywa futhi aphucuziwe ukuze abe nobukhulu obunembile, okuqinisekisa ukuthi imiphetho ebukhali yokusika kanye nokuqedwa kwendawo okubushelelezi. Zingaqhubeka ziphathwe ngezingubo zokwandisa ukumelana kwazo nokugqoka kanye ne-oxidation, okungathuthukisa ukusebenza kwazo ezinhlelweni ezithile.
Amathuluzi e-PCD ajwayele ukusetshenziselwa imisebenzi yokusika enembayo futhi azuzisa ngokukhethekile ezintweni zokwakha ezibangela ukuguga okuphawulekayo ezintweni zamathuluzi endabuko. Ngenxa yokuqina kwazo okungavamile kanye nezakhiwo eziphansi zokungqubuzana, ziletha ukusebenza okuvelele kokubili kokuqeda kanye nokusebenza komshini wejubane eliphezulu.

Umehluko Obalulekile:
Ukuhambisana Kwezinto ezibonakalayo:
I-CBN ifaneleka ngokukhethekile izinto eziqinile neziqhumayo njengezinsimbi eziqinile nensimbi ekhonjiwe.
I-PCD ilungele izinto ezithambile ezifana ne-aluminium, ithusi, nezinhlanganisela, ezivame ukuguga ngokushesha amathuluzi endabuko.
Ukusebenza Emazingeni Okushisa Aphakeme:
Amathuluzi e-CBN angakwazi ukumelana namazinga okushisa aphakeme ngaphandle kokwehlisa isithunzi, awenze asebenze kangcono ezimeni zamashini zamandla amakhulu nezishisa kakhulu.
Amathuluzi e-PCD, nakuba enzima kakhulu, awabekezeleli amazinga okushisa aphakeme kakhulu futhi angalahlekelwa umkhawulo wawo ngaphansi kwezimo ezinjalo.
Izindleko Ukucatshangelwa:
Amathuluzi e-CBN avame ukuthengeka kakhulu kunamathuluzi e-PCD, njengoba i-PCD idinga izinqubo zokukhiqiza eziyinkimbinkimbi futhi impahla eluhlaza ngokwayo ibiza kakhulu.
I-Surface Finish kanye Nokunemba:
Amathuluzi e-PCD afaneleka kakhulu ukuzuza ukuqedwa kwengaphezulu elicoliseke kakhulu, ikakhulukazi ezintweni ezingezona ayoni.
Amathuluzi e-CBN, nakuba enembile, ahamba kahle kakhulu ekuqineni nasekunciphiseni ukuqina kunokufinyelela isiphetho esiphezulu kakhulu ngezinto ezithambile.
Womabili amathuluzi okusika e-CBN kanye ne-PCD CNC anikeza ukusebenza okuhlukile, kodwa abhekelela izidingo zemishini ehlukene. Amathuluzi e-CBN alungele izinto eziqinile, eziqinile kanye nezicelo ezishisa kakhulu, kuyilapho amathuluzi e-PCD ekhanya lapho esebenza ngezinsimbi ezithambile nezinto eziyinhlanganisela, enikeza ukuphila kwamathuluzi okude nokusebenza okuhle kakhulu kokusika. Ukukhetha phakathi kwalokhu okubili kuncike ezintweni ezithile ezenziwa ngomshini, impilo yamathuluzi adingekayo, kanye nendawo yokwenza imishini.
