1. Sharaxaadda nooca Baakadaha Garaafiga
Waxaa jira 3 nooc oo buuxin ah oo caadi ahaan loo isticmaalo gudahawaalka
Baakadaha loo isticmaalay mashruucan waa nooca hal-furan ee ku jira Jaantuska 1aad iyo baakadaha qaabka giraanta ah ee ku jira Jaantuska 3aad. Sawirrada dhabta ah waa sidan soo socota:
Jaantuska 1 Nooca baakadaha hal-furan
Jaantuska 3 Baakaynta faraantiga baakadka
Hawlaha isticmaalka ee labada baakadood ee kor ku xusan waa isku mid, farqigu wuxuu ku jiraa xaaladaha isticmaalka ee kala duwan. Baakadda hal-furan waxay ku habboon tahay beddelka baakaynta inta lagu jiro dayactirka waalka maalinlaha ah. Baakadda waxaa lagu beddeli karaa khadka tooska ah, baakadda giraanta baakayntana waxay ku habboon tahay dib-u-hagaajinta waalka. Waxaa loo isticmaalaa kala-furka iyo dayactirka.
2. Sharaxaadda sifooyinka baakadaha garaafka
Sida waafaqsan shuruudaha farsamo ee wax soo saarka buuxinta, buuxintu waxay u baahan tahay inay lahaato heer adkeysi gaar ah, sidaa darteed waxaa jiri doona adkeysi gudaha ilaa dibadda ka dib marka buuxinta la sameeyo. Labada nooc ee buuxinta garaafka nooca hal-furan ee kor ku xusan waa buuxinta tidcan oo habka wax lagu sameeyo lagu tidcay fiilooyin badan oo garaafiti ah, adkeysigana waxaa nuugaya farqiga tidcan mana jirto raad cad oo muujinaya u hilowga ballaarinta. Garaafka baakadaha ee nooca giraanta ah waa baakad is haysta oo leh gudaha is haysta. Ka dib muddo dheer oo istaag ah, adkeysiga gudaha wuxuu muujin doonaa dildilaac dusha sare ee baakadda wuxuuna sii deyn doonaa qaybtan cadaadiska. Noocan buuxinta wuxuu ahaan doonaa mid deggan oo aan isbeddelin ka dib marka dildilaac gaar ah la soo saaro. Marka mar kale la cadaadiyo, dildilaacku wuu baaba'aa heerka dib u soo kabashadana wuxuu buuxiyaa shuruudaha.
Kuwa soo socda waa shuruudaha farsamo ee giraanta graphite dabacsan

3. Ku saabsan isticmaalka baakadaha garaafka
Baakaynta garaafka waxaa loo isticmaalaa meesha shaabadaysan ee u dhaxaysa jirridda waalka iyo qanjirka baakadka, baakaduna waxay ku jirtaa xaalad la cadaadiyey inta lagu jiro hawlgalka. Hadday tahay baakad hal-furan ah ama baakad giraanta baakadka ah, ma jirto wax farqi ah oo ku jira shaqada xaaladda la cadaadiyey.
Hoos waxaa ku qoran jaantuska xaaladda shaqada ee baakadda (sawirka tijaabada shaabadda baakadda)
