1. Indlela yokusebenza:
Vula umbane uze ulinde umzuzwana ukuze usete ubushushu.
Lungisa ivili lesandla ukuze isikhunta esisezantsi silingane neqonga elisezantsi. Beka isampuli apho umphezulu wokujonga ujonge ezantsi embindini wesikhunta esisezantsi. Jika ivili lesandla ngendlela echasene newotshi kangangezihlandlo ezili-10 ukuya kwezili-12 ukuze untywilisele isikhunta esisezantsi kunye nesampuli. Ukuphakama kwesampuli ngokubanzi akufuneki kube ngaphezulu kwe-1cm. .
Galela umgubo ongaphakathi ukuze ulingane neqonga elingezantsi, uze ucinezele i-mold ephezulu. Faka amandla ezantsi kwi-mold ephezulu ngomnwe wakho wasekhohlo, uze ujike ivili lesandla ngesandla sakho sasekunene ukuze i-mold ephezulu itsibe de umphezulu wayo ongaphezulu ube ngaphantsi kweqonga le-mold ephezulu.
Vala isigqubuthelo ngokukhawuleza, uze ujike ivili lesandla ngokwewotshi ude ukhanyise isibane soxinzelelo, uze wongeze ezinye iinguqu ezi-1 ukuya kwezi-2.
Gcina ubushushu obumiselweyo kunye noxinzelelo imizuzu emi-3 ukuya kwemi-5.
Xa uthatha iisampulu, qala ngokujika ivili lesandla ngendlela echasene newotshi ukuze unciphise uxinzelelo de isibane soxinzelelo sicime, uze ujike ngendlela echasene newotshi izihlandlo ezi-5, uze ujike iqhina elinomqolo osi-8 ngokwewotshi, utyhale imodyuli ephezulu iye ezantsi, uze ukhuphe isampuli.
Jika ivili lesandla ngokwewotshi ukuze ukhuphe isikhunta esingaphezulu ude umda ongezantsi wesikhunta esingaphezulu ulingane neqonga elisezantsi.
Sebenzisa ilaphu elithambileyo nesando somthi ukuze ukhuphe isikhunta esingaphezulu. Qaphela ukuba isikhunta esingaphezulu sishushu kwaye asinakubanjwa ngqo ngezandla zakho.
Phakamisa isikhunta esisezantsi uze ukhuphe isampuli emva kokuvezwa.
2. Amanyathelo okhuseleko kumatshini wokufaka i-metallographic ngala alandelayo:
Ngexesha lenkqubo yokucinezela isampuli, nceda ukhethe ubushushu bokufudumeza obufanelekileyo, ixesha lobushushu elingaguqukiyo, uxinzelelo kunye nezinto zokuzalisa, kungenjalo isampuli ayizukuba yalingana okanye iqhekeke.
Imiphetho yeemodyuli eziphezulu nezisezantsi kufuneka ihlolwe kwaye icocwe ngaphambi kokuba isampuli nganye ifakwe. Musa ukusebenzisa amandla amaninzi xa ucoca ukuze ungakrweli imodyuli yokulawula.
Umatshini wokufaka izinto ezishushu awufanelekanga kwiisampuli eziza kuvelisa izinto eziguquguqukayo nezinamathelayo kubushushu bokufaka.
Coca umatshini ngokukhawuleza emva kokusebenzisa, ingakumbi intsalela ekwimodyuli, ukuze ungachaphazeli ukusetyenziswa okulandelayo.
Akuvumelekanga ngokungqongqo ukuvula isigqubuthelo socango lwesixhobo ngokuthanda kwaso ngexesha lenkqubo yokufudumeza umatshini wokufakela i-metallographic ukuze kuthintelwe ingozi kumqhubi ngenxa yomoya oshushu.
3. Xa usebenzisa oomatshini bokufaka i-metallographic, kufuneka wazi oku kulandelayo:
Ukulungiselela isampuli yeyona nto iphambili ekulungiseleleni ngaphambi kokusebenzisa umatshini wokufaka i-metallographic. Isampuli eza kuvavanywa kufuneka isikwe ibe bukhulu obufanelekileyo kwaye umphezulu kufuneka ucoceke kwaye uthe tyaba.
Khetha ubungakanani bokubumba obufanelekileyo bokufakelwa ngokusekelwe kubungakanani besampulu kunye neemfuno.
Beka isampuli kwisikhunta sokufakela, uqiniseke ukuba ikwindawo efanelekileyo ngaphakathi kwisikhunta kwaye uphephe ukuhamba kwesampuli
Kufuneka uvavanyo oluninzi, kwaye kufuneka kukhethwe umatshini wokufaka izinto onokukwazi ukuvelisa izinto ezininzi, njengomatshini wokufaka izinto osebenza ngokuzenzekelayo ophezulu.
