Likarolo tsa Machining tsa Grey Iron CNC

Grey cast iron, e sebelisoang haholo ho etsa li-castings tse tloaelehileng ka ho lahla lehlabathe le letala, ho lahla hlobo ea khetla kapa mekhoa e meng ea ho lahla lehlabathe le omeletseng, e na le bothata bo bonolo bakeng sa machining a CNC. Grey iron, kapa grey cast iron, ke mofuta oa tšepe e entsoeng ka tšepe e nang le graphite microstructure. E bitsoa ka 'mala o moputsoa oa fracture eo e e etsang. The grey cast iron e sebelisoa bakeng sa matlo moo ho satalla ha motsoako ho leng bohlokoa ho feta matla a eona a thata, joalo ka li-cylinder tsa enjene e tukang ka hare, matlo a pompo, 'mele ea li-valve, mabokose a motlakase, boima ba li-counter le li-castings tse khabisitsoeng. Thermal conductivity ea Grey cast iron le matla a khethehileng a hlooho hangata a sebelisoa hampe ho etsa li-cookware tsa tšepe tse entsoeng ka tšepe le li-rotor tsa disc. Sebopeho se tloaelehileng sa lik'hemik'hale ho fumana microstructure ea graphite ke 2.5 ho 4.0% carbon le 1 ho 3% silicon ka boima ba 'mele. Graphite e ka nka 6 ho isa ho 10% ea molumo oa tšepe e bohlooho. Silicon ke ea bohlokoa ho etsa tšepe e bohlooho ho fapana le tšepe e tšoeu ea tšepe, hobane silicon ke karolo ea graphite e tsitsitseng ka tšepe e entsoeng ka tšepe, e bolelang hore e thusa motsoako ho hlahisa graphite ho e-na le li-carbides tsa tšepe; ka 3% silicon hoo e ka bang ha ho na carbon e tšoaroang ka lik'hemik'hale hammoho le tšepe. graphite e nka sebōpeho sa letlapa la mahlakore a mararo. Ka litekanyo tse peli, ha sebaka se bentšitsoeng se tla hlaha ka tlas'a microscope, li-flakes tsa graphite li hlaha e le mela e metle. Grey iron e boetse e na le matla a matle haholo a ho phopholetsa, ka hona e sebelisoa haholo joalo ka motheo oa lisebelisoa tsa mochini.
