Kawirikawiri pamene kuuma kwa zinthu kuli kwakukulu, kuvala kukana kumakhalanso kwakukulu;mkulu flexural mphamvu, zotsatira toughness ndi mkulu.Koma kuuma kwa zinthu kumakwera, mphamvu yake yopindika ndi kulimba kwake kumatsika.Chitsulo chothamanga kwambiri chifukwa cha mphamvu yopindika kwambiri komanso kulimba kwamphamvu, komanso makina abwino, akadali zida zogwiritsidwa ntchito kwambiri, zotsatiridwa ndi carbide.
Polycrystalline kiyubiki boron nitride ndi oyenera kudula mkulu kuuma chitsulo cholimba ndi chitsulo cholimba, etc.;Polycrystalline diamondi ndi oyenera kudula zitsulo zopanda chitsulo, ndi kabisidwe, mapulasitiki ndi galasi zitsulo, etc.;Chitsulo chachitsulo cha carbon ndi alloy chida chitsulo tsopano chimangogwiritsidwa ntchito ngati mafayilo, mano a mbale ndi matepi ndi zida zina.
Zolozera za Carbide tsopano zakutidwa ndi titanium carbide, titanium nitride, aluminium oxide hard layer kapena composite hard layer ndi kuyika kwa nthunzi wa mankhwala.Kuyika kwa mpweya wakuthupi kukupangidwira osati zida za carbide zokha komanso zida za HSS monga zobowolera, ma hob, matepi ndi zodulira mphero.Chophimba cholimbacho chimakhala ngati chotchinga kufalikira kwa mankhwala ndi kutengera kutentha, kumachepetsa kuvala kwa chida panthawi yodula, ndikuwonjezera moyo wa zoyikapo zokutira pafupifupi 1 mpaka 3 nthawi kapena kuposerapo poyerekeza ndi zosaphimbidwa.
Chifukwa cha kutentha kwambiri, kuthamanga kwambiri, kuthamanga kwambiri, komanso m'zigawo zogwirira ntchito zamadzimadzi zowononga, kugwiritsa ntchito zipangizo zovuta kumakina kumachulukirachulukira, kuchuluka kwa makina odulira ndi makina ndi kulondola kwa makina akuchulukirachulukira.Kuti mugwirizane ndi izi, malangizo a chitukuko cha zida adzakhala chitukuko ndi kugwiritsa ntchito zipangizo zatsopano;kupititsa patsogolo luso lazopaka utoto la chipangizocho, pakulimba kwambiri komanso kulimba kwakukulu kwa gawo lapansi lomwe limayikidwa pa zokutira kuuma kwapamwamba, njira yabwino yothetsera kutsutsana pakati pa kuuma kwa zida ndi mphamvu ya chida;kupititsa patsogolo kamangidwe ka chida cholozera;kukonza zolondola kupanga chida kuchepetsa kusiyana mankhwala khalidwe mkulu manganese zitsulo ndi zovuta makina zipangizo.Zofunikira zapamwamba za zida za zida.
　　

Nthawi zambiri, zofunika chida zinthu red kuuma, chabwino kuvala kukana, mphamvu mkulu, toughness ndi matenthedwe matenthedwe madutsidwe.Kudula mkulu manganese zitsulo akhoza kusankha carbide, cermet kuchita kudula zida zakuthupi.Pakalipano, ntchito yodziwika kwambiri imakhalabe ndi simenti ya carbide, yomwe mtundu wa YG wa carbide wopangidwa ndi simenti uli ndi mphamvu zosunthika komanso zolimba kwambiri (poyerekeza ndi mtundu wa YT wa carbide wopangidwa ndi simenti), zomwe zimatha kuchepetsa kutsetsereka podula.Panthawi imodzimodziyo, YG carbide imakhala ndi matenthedwe abwino kwambiri, omwe amathandiza kuti pakhale kutentha kwa kutentha kuchokera ku nsonga ya chida, kuchepetsa kutentha kwa nsonga ya chida ndikupewa nsonga ya chida kuti isatenthedwe ndi kufewetsa. kugaya processability wa YG carbide ndi bwino, ndipo akhoza akuthwa kutulutsa lakuthwa m'mphepete.
Nthawi zambiri, kulimba kwa chidacho kumadalira kuuma kofiyira, kukana kuvala komanso kulimba kwa chidacho.Pamene mtundu wa YG wa carbide woyima uli ndi cobalt yochulukirapo, mphamvu yopindika ndi kulimba kwamphamvu ndizabwino, makamaka mphamvu ya kutopa imakhala bwino, kotero ndi oyenera roughing pansi chikhalidwe cha kukhudza ndi kugwedera;pamene ili ndi cobalt yocheperapo, kuuma kwake, kukana kuvala ndi kukana kutentha ndipamwamba, koyenera kutsiriza kudula kosalekeza.
