Imibhobho yokusetyenziswa koomatshini kunye nokukhanya kwesakhiwo.Oku kuvumela ukufana okuthe ngqo kweempawu kuwo wonke umbhobho xa kuthelekiswa nemibhobho eqhelekileyo okanye imibhobho.Iityhubhu zoomatshini zinokuveliswa kwiinkcukacha ezisemgangathweni xa zifunwa, kodwa ngokuqhelekileyo ziveliswa ukuba zisebenze "eziqhelekileyo", ngokugxininiswa okuphambili kumandla okuvelisa imilinganiselo echanekileyo kunye nobukhulu bodonga.Kwezinye izicelo ezenziwe kakhulu, amandla okuvelisa angenakuchazwa, kwaye ukuveliswa kweetyhubhu zomatshini "kufanelekile ukusetyenziswa".Imibhobho yoomatshini ibandakanya uluhlu olubanzi lwezicelo zesakhiwo kunye nezingezizo ezobume.
Sisebenzisa ubuchule bethu be-metallurgical kunye nemveliso ukwenza iimveliso zetyhubhu ezinomthungo ezikumgangatho ophezulu wokuhlangabezana neemfuno zakho.
Oku kubandakanya i-carbon, i-alloys kunye namabakala entsimbi yesiko;i-annealed, iqhelekile kwaye inomsindo;uxinzelelo luthotyiwe kwaye alunaxinzelelo;waza wathomalalisa umsindo.
Imibhobho yentsimbi engenamthungo yoomatshini kunye neemoto, ezisetyenziselwa ukwenziwa kunye nokusetyenzwa kwetrunk yemoto kunye nemibhobho ye-axle yangasemva, izixhobo ezichanekileyo, izixhobo kunye nezixhobo.
Isakhelo semoto kunye netyhubhu ye-axle yangasemva.
Ukwenziwa kunye nokulungiswa kwezixhobo ezichanekileyo, izixhobo kunye nezixhobo.
Amagama okuhanjiswa: GBK, BKS, BK, BKW, NBK.
Jonga kwaye uvavanye:Ukwakheka kweekhemikhali, iipropathi zoomatshini, uvavanyo lwenkangeleko kunye nobukhulu, uvavanyo olungonakalisi, uvavanyo lobungakanani bamasuntswana.
Unyango lomphezulu:Ukuntywiliselwa kwe-oyile, ivanishi, ukuchama kwe-oyile.
