Izici Zokusebenza Ezimangalisayo Zokufakwa Kwe-PCBN Composite

1. Ukuqina Okuphezulu Nokumelana Okuvelele Kokugqoka

I-Pcbn Composite Izithako zikhombisa ubulukhuni obuncane obungu-2700–5000 HV, obulandela idayimane kuphela futhi buphakeme kakhulu kune-silicon carbide ne-aluminium oxide. Ukumelana kwazo nokuguguleka kukhulu ngokuphindwe ka-50 kunokwamathuluzi e-carbide, kukhulu ngokuphindwe ka-30 kunokwamathuluzi e-carbide amboziwe, futhi kukhulu ngokuphindwe ka-25 kunokwamathuluzi e-ceramic. Lokhu kuzenza zifaneleke kakhulu ekushicileleni izingcezu zokusebenza ezinobulukhuni obuphezulu, okuholela ekhwalithini ephezulu ebusweni futhi kube lula kakhulu izinqubo zokwelapha ukushisa.

2. Ukuqina Kwamakhemikhali Okuhle Kakhulu

I-PCBN Amathuluzi abonisa ukuzinza okuphawulekayo ezindaweni ezifinyelela amazinga okushisa angu-1200–1300°C, ephikisana nokusabela kwe-asidi kanye ne-alkali, okwenza kube kuhle kakhulu ekukhiqizeni izinsimbi zensimbi.

3. Ukuzinza Okuphezulu Kokushisa Okuphezulu

I-PCBN Amathuluzi angamelana namazinga okushisa angu-1400–1500°C, cishe kabili ukumelana nokushisa kwedayimane. Aphelele ekusetshenzisweni kwe-superalloys nezinsimbi eziqinile ngesivinini esikhulu, ngesivinini sokusika esiphindwe kane kuya kweziyisithupha kunamathuluzi e-carbide.

4. Ukushisa Okuphezulu Kokushisa

Njengoba i-thermal conductivity ilandela idayimane kuphela, i-CBN yenza kahle kakhulu kune-carbide. Lokhu kuthuthukiswa kokudlulisa ukushisa kunciphisa izinga lokushisa endaweni yokusika, ngaleyo ndlela kwandise isikhathi sokuphila kwethuluzi.

5. I-Coefficient Ephansi Yokungqubuzana

I-coefficient yokungqubuzana phakathi kwe-PCBN nezinto ezahlukahlukene iphansi kakhulu kuneye-carbide, iyancipha njengoba isivinini sokusika sanda. Lokhu kuphumela ekunciphiseni amandla okusika kanye nokunamathela okuncishisiwe kwe-chip.

Izicelo Ezibanzi Zokufakwa Kwe-PCBN Composite

Izici ezingavamile ze I-PCBN yenze kube ukukhetha okuphezulu kokulungisa izinto ezinzima, ikakhulukazi ekusikeni okunembe kakhulu ngesivinini esikhulu. Ukusetshenziswa kwayo kuhlanganisa izimboni ezahlukene, okuhlanganisa ukukhiqiza izimoto, izindiza, kanye nemishini esindayo.

• Ukusatshalaliswa KwemboniImboni yezimoto ingama-50.37%, imishini esindayo ingu-20.74%, kanye nokukhiqizwa kwamaphampu kungu-8.89%.
• Ukusatshalaliswa Kwezinto EzibalulekileInsimbi ecinyiwe ingama-65%, kuyilapho insimbi ecinyiwe ingama-28%.
• Imisebenzi Yomshini: Imisebenzi yokujika imele u-60%, kanti ukubumba ku-32.5%.
• Izinhlelo Zokufaka Ezintsha: 50% yokusetshenziswa kwe-PCBN iwukufaka esikhundleni sokugaya, 30% ukufaka esikhundleni samathuluzi e-carbide.

Isibonelo, selokhu wethula Ukufakwa kwe-Pcbn Ngo-2005, iBeijing West Industries ibone isivinini sokunciphisa kabili esamathuluzi obumba, isikhathi sokuphila kwamathuluzi sikhula ngokuphindwe kathathu kuya kane, okwandisa kakhulu ukusebenza kahle kokukhiqiza nokunciphisa izindleko.

Ukukhetha Okuqondiwe Nokwakhiwa

I-PCBN Amathuluzi akhethekile kakhulu, adinga ukwakheka okuhlukene okusekelwe ezintweni zokwakha nezindlela zomshini. Uma okuqukethwe kwe-CBN kuphakeme, kulapho ukuqina kwethuluzi, ukumelana nokuguguleka, kanye nokushisa kukhulu khona. Ngokuvamile kuhlukaniswa ngokuqukethwe kwe-CBN okuphezulu, okuphakathi, nokuphansi, lokhu kufakwa kwenzelwe ukuhlangabezana nezidingo ezahlukene zomshini.

• Okuqukethwe Okuphezulu (80%–95%): Kuhle kakhulu ngensimbi ephothiwe, i-powder metallurgy, kanye nama-superalloy.
• Okuqukethwe Okumaphakathi (60%–80%): Ifaneleka ekucubunguleni insimbi ecinyiwe esebenza kanzima.
• Okuqukethwe Okuphansi (40%–60%): Kungcono kakhulu ekusetshenzisweni komshini wokukhanya okusheshayo nomthwalo oqhubekayo.

Ngokwezidingo zokunemba kanye nekhwalithi yobuso, izinhlayiya ze-CBN zitholakala ngobukhulu obukhulu, obuphakathi, nobuncane ukuze kuhlangatshezwane nezidingo ezahlukene zokucubungula.

Ngezici zayo zokusebenza ezivelele, i-Boreas' I-PCBN Izithako ezihlanganisiwe zivelele njengokukhetha okuhle kakhulu kokucubungula izinto eziyinselele. Khetha i-Boreas yezidingo zakho ze-PCBN futhi uphakamise ukusebenza kahle kokukhiqiza kwakho ngenkathi unciphisa izindleko. Zizwa ikhwalithi nokuthembeka okungenakuqhathaniswa kwemikhiqizo yethu bese ujoyina inani elikhulayo lamakhasimende anelisekile athemba i-Boreas ngezixazululo zabo zomshini. Ake sikusize ufeze ubuhle emisebenzini yakho—xhumana nathi namuhla ukuze ufunde kabanzi mayelana ne-PCBN yethu. I-PCBN iminikelo!
