Izixhobo ezigqunyiweyo zomelele kwaye ziqine i-carbide okanye intsimbi yesantya esiphezulu (
I-Ceramics, idayimani kunye ne-cubic boron nitride imathiriyeli enzima kakhulu efana neencakuba zencakuba nazo zinakho)
Kumphezulu, usebenzisa indlela yokubeka umphunga umaleko wentsimbi exhathisayo ekwazi ukumelana nokunxitywa okanye ikhompawundi engekho ntsimbi kunye nokulungiselela.
Ukugquma njengesithintelo sekhemikhali yesixhobo sokusika kunye nesithintelo se-thermal, kunokunciphisa ukusabalalisa kunye nokusabela kweekhemikhali phakathi kwe-cutter kunye ne-workpiece, ngaloo ndlela ukunciphisa i-matrix yokugqoka kunye nokukrazula, ukwenzela ukuba kuphuculwe ubomi benkonzo yezixhobo zokusika.
Izixhobo ezigqunyiweyo zinobulukhuni obuphezulu bomphezulu kunye nokumelana nokunxiba, iipropathi ezizinzileyo zeekhemikhali, ukumelana nobushushu obulungileyo kwi-oxidation, i-friction coefficient ephantsi kunye ne-thermal conductivity ephantsi, inokunciphisa i-adhesion phenomenon, akukho lula ukuvelisa ithumba le-devolop njl. kunobomi besixhobo sokusika esingafakwanga kunye nesantya sokusika sigudileyo, ngakumbi kunokunciphisa ukulahleka kwesixhobo sokusika.
Izixhobo ezigqunyiweyo ziya kwahlulwa zibe ziindidi ezine: izixhobo zentsimbi ezinesantya esiphezulu, izixhobo zokusika i-carbide egqunyiweyo, kunye neeseramikhi kunye nezinto ezinzima kakhulu (
Idayimane okanye cubic boron nitride)
Iblade kwizixhobo ezigqunyiweyo.
Kodwa ngaphambi kokuba iintlobo ezimbini zezixhobo ezigqunyiweyo zisebenzise kakhulu.
Kwi-ceramics kunye neengubo zemathiriyeli enzima kakhulu kwi-blade ukuqina kwakungaphantsi kunezo zemathiriyeli ye-matrix, injongo kukuphucula ukuqina kokuqhekeka komphezulu we-blade (
Inokunyusa ngaphezulu kwe-10%)
, inokunciphisa umda we-blade kwaye yonakaliswe, yandise uluhlu lwesicelo.
