Pali magawo angapo a zida za carbide zomwe zimagwiritsidwa ntchito podula matabwa, monga macheka ozungulira, macheka a band, odula mphero, mipeni yokopera, etc. za nkhuni zikudulidwa. Makhalidwe: Sankhani carbide yoyenera. M'munsimu muli mndandanda wa carbide ofanana ndi zipangizo zosiyanasiyana.

1. Tinthu bolodi, kachulukidwe bolodi, ndi tinthu bolodi. Ma board awa amapangidwa makamaka kuchokera kumitengo, guluu wamankhwala, ndi mapanelo a melamine. Amadziwika ndi mapanelo olimba, zomatira zapamwamba kwambiri mkati mwake, ndi gawo lina la zonyansa zolimba. Panthawi yodulira, mafakitale amipando amakhala ndi zofunikira kwambiri pamabowo a gawo lodulira, kotero mtundu uwu wa matabwa nthawi zambiri umasankha carbide yokhala ndi simenti yokhala ndi kuuma kwa Rockwell kwa madigiri 93.5-95. Zida za alloy makamaka zimasankha tungsten carbide ndi carbide yotsika kwambiri yokhala ndi njere zosakwana 0.8um. M'zaka zaposachedwapa, chifukwa m'malo ndi kusinthika kwa zipangizo, opanga mipando ambiri pang'onopang'ono ntchito gulu diamondi macheka masamba m'malo carbide macheka masamba kudula mu gulu macheka pakompyuta. Daimondi yophatikizika imakhala yolimba kwambiri ndipo imakhala yolimba pakugwiritsa ntchito. Panthawi yodulira mapanelo opangira, zomatira ndi kukana kwa dzimbiri ndizabwino kuposa za carbide yomangidwa. Malinga ndi ziwerengero za kagwiridwe ka ntchito m'munda, moyo wautumiki wa masamba ophatikizika a diamondi ndi pafupifupi kuwirikiza ka 15 kuposa mabala a simenti a carbide.

2. Mitengo yolimba Mitengo yolimba imatanthawuza mitundu yosiyanasiyana ya matabwa achilengedwe. Mitundu yosiyanasiyana ya nkhuni imakhala ndi zovuta zosiyanasiyana zodula. Makina ambiri opanga zida nthawi zambiri amasankha ma aloyi okhala ndi madigiri 91-93.5. Mwachitsanzo, mfundo zamatabwa za nsungwi ndi zolimba koma matabwa ndi osavuta, choncho alloy yokhala ndi kuuma kwa madigiri oposa 93 nthawi zambiri amasankhidwa kuti atsimikizire kuthwa bwino; zipika zokhala ndi zipsera zambiri zimatsindikitsidwa mosagwirizana panthawi yodula, kotero tsamba Mukakumana ndi zipsera, ndizosavuta kuyambitsa m'mphepete mwake. Chifukwa chake, aloyi pakati pa madigiri 92-93 nthawi zambiri amasankhidwa kuti atsimikizire kuthwa kwina komanso kukana kwa chip. Mitengo yokhala ndi zipsera zochepa komanso matabwa ofanana ndi abwino. Aloyi yokhala ndi kuuma pamwamba pa madigiri 93 idzasankhidwa. Malingana ngati kukana kuvala kwakukulu ndi kukhwima kumatsimikiziridwa, kumatha kudulidwa kwa nthawi yaitali; mitengo yachibadwidwe kumpoto idzapanga matabwa oundana chifukwa cha kuzizira kwambiri m’nyengo yachisanu, ndipo matabwa oundanawo adzawonjezera kuuma kwa nkhunizo. Ndipo kudula matabwa oundana m'malo ozizira kwambiri ndikosavuta kumayambitsa kuphulika, kotero pamenepa, ma aloyi okhala ndi madigiri 88-90 nthawi zambiri amasankhidwa kuti adulidwe.

3. Mitengo yachidebe: Mitengo yamtunduwu imakhala ndi zonyansa zambiri. Mwachitsanzo, matabwa omwe amagwiritsidwa ntchito pomanga nthawi zambiri amakhala ndi simenti yambiri, ndipo matabwa omwe amagwiritsidwa ntchito pochotsa mipando nthawi zambiri amakhala ndi misomali yamfuti kapena misomali yachitsulo. Choncho, pamene tsamba likugunda chinthu cholimba panthawi yodula, Zimayambitsa kudulidwa kapena kuthyoka m'mphepete, kotero ma alloys okhala ndi kuuma pang'ono komanso kulimba kwambiri nthawi zambiri amasankhidwa podula nkhuni zamtunduwu. Mtundu uwu wa aloyi nthawi zambiri umasankha tungsten carbide yokhala ndi sing'anga mpaka kukula kwambewu, ndipo zomwe zili mugawo la binder ndizokwera kwambiri. Kuuma kwa Rockwell kwa mtundu uwu wa aloyi nthawi zambiri kumakhala pansi pa 90. Kuwonjezera pa kusankha carbide kwa matabwa kudula zida zochokera makhalidwe a kudula matabwa, fakitale chida kawirikawiri amachitanso kuwunika mabuku zochokera kupanga ndi processing luso lake, zipangizo fakitale mipando ndi luso ntchito ndi zinthu zina zokhudzana, ndipo potsiriza amasankha mmodzi. ndi zofananira bwino wa carbide wopangidwa ndi simenti.
