Njira yodulira imatenga pafupifupi 90% ya ntchito yokonza makina.Chidacho ndi "dzino" la chida cha makina a mafakitale, chomwe chimakhudza mwachindunji mlingo wa kukonza mafakitale.Kudula amatanthauza kudula zinthu owonjezera kuchokera workpiece pamwamba, kuonetsetsa kuti workpiece geometry, dimensional zolondola, pamwamba khalidwe ndi mbali zina za kapangidwe zofunika za njira Machining, mlandu pafupifupi 90% ya lonse Machining ntchito.Kudula nthawi zambiri kumatheka ndi kudula zida zamakina, ndipo chidacho ndi chinthu chofunikira kwambiri, monga "mano" a zida zamakina amakampani, mawonekedwe ake amakhudza mwachindunji kupanga makina opanga luso laukadaulo, kugwiritsa ntchito bwino komanso mtundu wazinthu.Zida zodulira kumtunda kwa opanga zinthu zopangira, zomwe zimagwiritsidwa ntchito m'mafakitale akuluakulu opanga zinthu.Tengani chida chodziwika bwino kwambiri cha carbide monga chitsanzo, malinga ndi zida zosinthidwa zitha kugawidwa mu: chitsulo, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri, chitsulo chosakhala ndi chitsulo, aloyi yosagwira kutentha, chitsulo chowumitsidwa, etc. Kumtunda kwa zopangira zofananira ( tungsten carbide, cobalt ufa, tantalum niobium olimba njira, etc.) opanga, kunsi mtsinje ntchito munda anaikira mu makampani opanga, makamaka ntchito galimoto ndi njinga yamoto, zida makina, makina ambiri, nkhungu, makina zomangamanga ndi madera ena, zakuthambo, asilikali, makina azachipatala ndi madera ena amaperekanso yotakata luso ntchito ndi kusintha malo zida carbide.
Kodi zida zodulira carbide ndi ziti?
1.kuuma kwakukulu: Chida cha carbide chimapangidwa ndi carbide yokhala ndi kuuma kwakukulu ndi malo osungunuka (otchedwa gawo lolimba) ndi binder yachitsulo (yotchedwa gawo lomanga) ndi njira yazitsulo ya ufa, kuuma kwake ndi 89 ~ 93HRA, kuposa chitsulo chothamanga kwambiri. , pa 5400C, kuuma kungathebe kufika 82 ~ 87HRA, ndi kuuma kwa kutentha kwa chipinda chachitsulo (83 ~ 86HRA) mofanana.
2. Mphamvu yopindika ndi kulimba: mphamvu yopindika ya aloyi wamba yolimba imakhala mumitundu ya 900 ~ 1500MPa.The apamwamba zili zitsulo kumanga gawo, ndi apamwamba kupinda mphamvu kupinda.Pamene zomangira zili zofanana, YG(WC-Co).Mphamvu ya alloy ndi yoposa YT (WC-Tic-Co) alloy, ndipo mphamvu imachepa ndi kuchuluka kwa TiC.Aloyi yolimba ndi mtundu wazinthu zowonongeka, kulimba kwake kutentha ndi 1/30 ~ 1/8 ya HSS.
3. Good kuvala kukana.Kuthamanga kwa chida cha carbide ndi 4 ~ 7 nthawi zambiri kuposa chitsulo chothamanga kwambiri, ndipo moyo wa chida ndi 5 ~ 80 nthawi zambiri.Kupanga nkhungu, zida zoyezera, moyo kuposa aloyi chida zitsulo 20 ~ 150 nthawi apamwamba.Itha kudula 50HRC kapena zinthu zolimba kwambiri.
