Ukucima kuyindlela ebalulekileyo kunyango lobushushu betsimbi, olutshintsha iimpawu ezibonakalayo kunye nomatshini wezinto eziphathekayo ngokupholisa ngokukhawuleza. Ngexesha lokucima, i-workpiece ingena kwizigaba ezifana nokufudumeza okuphezulu, ukufudumala, kunye nokupholisa ngokukhawuleza. Xa i-workpiece ipholile ngokukhawuleza kwiqondo lokushisa eliphezulu, ngenxa yokunciphisa ukuguqulwa kwesigaba esiqinileyo, i-microstructure ye-workpiece iyatshintsha, yenze izakhiwo zengqolowa entsha kunye nokusabalalisa uxinzelelo ngaphakathi.
Emva kokucima, i-workpiece ihlala kwindawo yokushisa ephezulu kwaye ayikakapholi ngokupheleleyo kwiqondo lokushisa. Ngeli xesha, ngenxa yomahluko obalulekileyo wokushisa phakathi kwendawo yokusebenza kunye nokusingqongileyo, i-workpiece iya kuqhubeka nokudlulisa ubushushu ukusuka phezulu ukuya ngaphakathi. Le nkqubo yokudlulisa ubushushu inokukhokelela kwiqondo lokushisa lasekhaya ngaphakathi kwendawo yokusebenza, oku kuthetha ukuba ubushushu kwiindawo ezahlukeneyo ngaphakathi kwendawo yokusebenza ayifani.
Ngenxa yoxinzelelo olushiyekileyo kunye notshintsho lwesakhiwo olwenziwe ngexesha lokucima, amandla kunye nobunzima bomsebenzi womsebenzi uya kuphuculwa kakhulu. Nangona kunjalo, olu tshintsho lunokunyusa ukunyanzeliswa komsebenzi kwaye lunokubangela iziphene zangaphakathi ezifana nokuqhekeka okanye ukuguqulwa. Ngoko ke, kuyimfuneko ukwenza unyango olushushu kwi-workpiece ukuphelisa uxinzelelo olushiyekileyo kunye nokufezekisa ukusebenza okufunekayo.
I-Tempering yinkqubo yokufudumeza i-workpiece kwiqondo lokushisa elithile kwaye emva koko liyipholise, ngenjongo yokuphucula i-microstructure kunye neempawu eziveliswa emva kokucima. Ubushushu bobushushu buhlala buphantsi kunobushushu bokucima, kwaye ubushushu obufanelekileyo bunokukhethwa ngokusekelwe kwiimpawu kunye neemfuno zezinto. Ngokuqhelekileyo, iqondo lokushisa eliphakamileyo liphezulu, lisezantsi ubulukhuni kunye namandla omsebenzi, ngelixa ukuqina kunye neplastiki ikhula.
Nangona kunjalo, ukuba i-workpiece ayipholiswanga kwiqondo lokushisa, oko kukuthi, isekho kwiqondo lokushisa eliphezulu, unyango lokufudumala alunakwenzeka. Oku kungenxa yokuba ukufudumeza kufuna ukufudumeza i-workpiece kwiqondo elithile lobushushu kwaye uyibambe ixesha elithile ukuze ufezekise umphumo oyifunayo. Ukuba i-workpiece sele ikwiqondo lokushisa eliphezulu, inkqubo yokufudumala kunye ne-insulation ayinakwenzeka, okuya kubangela ukuba umphumo wokufudumala ungahlangabezani nokulindela.
Ngoko ke, ngaphambi kokuba kuqhutywe unyango oluvuthayo, kuyimfuneko ukuqinisekisa ukuba i-workpiece ipholile ngokupheleleyo kwiqondo lokushisa okanye kufuphi neqondo lokushisa. Kungale ndlela kuphela apho unyango olusebenzayo lokuthambisa lunokwenziwa ukulungelelanisa ukusebenza komsebenzi kunye nokuphelisa iziphene kunye noxinzelelo olwenziwe ngexesha lokucima.
Ngamafutshane, ukuba i-workpiece ecinyiweyo ayipholiswanga kwiqondo lokushisa, ayiyi kukwazi ukufumana unyango olushushu. Ukufudumala kufuna ukufudumeza i-workpiece kwiqondo lokushisa elithile kunye nokugcina ixesha elithile, kwaye ukuba i-workpiece sele ikwiqondo lokushisa eliphezulu, inkqubo yokufudumala ayikwazi ukuphunyezwa ngokufanelekileyo. Ngoko ke, kubaluleke kakhulu ukuqinisekisa ukuba i-workpiece ipholile ngokupheleleyo kwiqondo lokushisa ngaphambi kokufudumala ngexesha lenkqubo yokushisa ukushisa ukuqinisekisa ukuba i-workpiece inokufezekisa ukusebenza okufunekayo kunye nomgangatho.
