1.Characters o CA hanga e te tikanga sol-rā

CA, whakaputaina e te tikanga sol-rā, ko te ahua o purapura auaha sintered. Na kua huaina hoki reira rite witi auaha SG. Ko te āhuatanga karaihe iti rawa, i te mea 100-500nm anake, a ko reira anake iti kotahi-ōrau corundum noa rahi karaihe o. He wahi o 46 # witi kei pirioni o matūriki karaihe. A, no te huri, hei nga purapura o tuku iho alumina tauta hiko flat, me te deactive, a ngāwari mai atu i taputapu auaha raro i te kaha huri. He poto Ko tōna ora ratonga. Heoi, hoki CA, ie SG purapura auaha, ko ano hoki te tukanga mau katoa tona tukanga whaiaro-whakakoi. I roto i tona ora mahi, he hora i tonu te mata huri koi tonu, hou ina tae atu passivating purapura karaihe pai i te taputapu huri i raro i te kaha huri, e hanga tonu nga purapura i roto i te mana koi. Na, ko nga taputapu auaha i hanga e CA o ropu ora roa, kaha whaiaro-whakakoi pai, pai whakairo tiketike, me te kore tahu workpieces.

Nā ki tona microstructure rerekē, whakaatu ana CA rerekētanga i runga i whanonga purapura whati auaha. E whakaatu ana CA haere te karaihe kino whati, i whakaatu tikanga alumina tauta hiko kino whati transgranular. Na reira, ko te rua atu i taua o te alumina tauta noa te taikaha o CA.

CA whakaputaina e tikanga sol-rā he hanganga matū rite, me te pakeke ki WFA (White tauta Alumina). Nā ki tona kākahu hanganga microcrystalline iti, taikaha tiketike, me te mahi whati iti, e taea te whānui te whakamahi CA mō te huri o ngā rauemi uaua-ki-tukanga rite taputapu maitai, uaua tira pokekore, wera-ātete koranu maitai, me ētahi atu

 2.Features o taputapu auaha i hanga e CA

(1)  He tino koi nga purapura, i hanga kua reira kaha whakairo kaha, tōtika huri tiketike. Ka taea te whakamahi i te reira no te kotinga nui hohonu, kai te mata ano, ohipa taimaha me te huri pai tiketike. E ai ki te whakamātau, ka taea e kai tukanga kotahi tae 0.3mm atu ranei, he neke atu i te rua o wira huri corundum noa auau tango whakarewa.

(2) taikaha pai, abrasion iti, me huri wira ki te pupuri hanga pai. Hoki pū huri me te puka huri, e taea te ngāwari ka tika teitei ahu, me te rahi āhua ōritetanga.

(3) mauroa High me te ora ratonga roa. Ka taea e tae te reira i 5 tau 10 wa o wira huri corundum noa. Ka taea e auau whakakapinga iti whakaiti wa tukatuka pŭpŭ tauturu, me te downtime, e hanga hāngai reira ki te whakamahi o te mana tau mīhini aunoa, te ite production aunoa.

(4) pai mahi whaiaro-whakakoi, e kore e tanumia. Ka taea e pupuri i te reira mahi huri on, whakaiti ako (anake e pā ana ki 1/3 o nga wira corundum huri noa), me te whakapai ake i hanga tōtika.

(5) I roto i te huri mahi, he tawhiti pai atu wira huri corundum noa huri CA wira. Hoki te utu, he nui raro atu CBN me taimana abrasives CA, i te mea kei rite ki taua o alumina tauta noa, e hanga ana e ia e kore e hiahia ana meafaigaluega huri motuhake me ngā pūrere whakatikatika ona pakeke. Na te mea kahore whakaritenga motuhake mō te huri meafaigaluega me kahore uauatanga hanganga whakaritea ki CBN me abrasives taimana. Reira hoki e kore whakaritenga motuhake mō te huri inu. Na, e mea ohie ki te horapa te whakamahi o reira.
