Ama-rolleryizinyathelo ezibaluleke kakhulu ku-inqubo yokwakheka kokugoba okubandayoNgakho-ke, izinto ezikhethiwe ze-roller nazo ziyisici esibalulekile ekwahluleleni ikhwalithi ye-umshini wokwakha umquluUkukhethwa kwezinto ezihlukene zama-roller kuzodala umehluko omkhulu ngekhwalithi yephrofayili kanye nezindleko zokukhiqiza. Emakethe yemishini yokwakha ama-roll yaseShayina, izinto ezisetshenziswa kuma-roller zivame ukuhlukaniswa ngezinhlobo ezilandelayo: insimbi engu-45, insimbi engu-45 efakwe ngogesi nge-Cr, GCr15, Cr12, Cr12MOV, njll.
Abakhiqizi abaningi bazoshintsha nama-roller abe yinsimbi ukuze bonge izindleko. Abathengi kudingeka bahlukanise ngokucophelela lapho uthenga imishini. Ngenxa yokuqukethwe kwensimbi okuhlukile kwezinto zamakhemikhali i-C, Cr, MO, V, njll. kwezinhlobo eziningana zezinto ezishiwo ngenhla, ukusebenza kwenqubo kanye nentengo kuhlukile kakhulu, ngakho-ke ukusetshenziswa ekukhiqizeni nakho kuhlukile. Kuma-coil ajwayelekile anamandla okukhiqiza angaphansi kuka-330Mpa kanye nobubanzi bobukhulu obungaphansi kuka-1.5mm, njengamashidi ashisiwe ashisayo, amashidi ashisiwe abandayo, i-PPGI, insimbi egayiwe, insimbi engu-45 noma insimbi engu-45 ene-chrome ingahlangabezana nezidingo. Ukuze kuvinjelwe ama-roller ukuthi angagqwali futhi kwandiswe impilo yenkonzo yama-roller, i-Linbay Machinery isebenzisa inqubo ye-chrome plating kuwo wonke ama-roller ensimbi angu-45 (ubukhulu be-chrome plating bungu-0.05mm), kanti ubunzima ngemva kokwelashwa kokushisa bungafinyelela ku-58-62HRC, okucishe kufane nobunzima be-Cr12 ne-GCr15. Ngenkathi kunciphisa izindleko, kuba nekhwalithi enhle ngesikhathi esifanayo. Uma ufuna ukukhiqiza amakhoyili anamandla aphezulu anamandla okukhiqiza angaphezu kwama-350Mpa noma amakhoyili ensimbi engagqwali, iLinbay Machinery izokhetha i-GCr15 noma i-Cr12 njengezinto zokwakha ama-roller, ezibiza kakhulu. Lezi zinto ezimbili zinokumelana nokuguguleka okuphezulu, ukuzinza kokushisa kanye namandla okucindezela, ukusebenza okuhle kakhulu. Phakathi kwazo, ingxenye ye-Cr12 ilingana ne-American Standard D3. Ngaphezu kokusetshenziswa njengento yokugoqa, i-Cr12 ivame ukusetshenziswa njengento yokubhoboza, yokudaya, kanye neyokufaka. Izinto ezisezingeni eliphezulu kakhulu zama-roller yi-Cr12Mov noma i-Japanese standard SKD11 noma i-American standard D2, ebiza kakhulu uma iqhathaniswa nezinye, inokumelana nokuguguleka okuphezulu futhi inokuphila isikhathi eside kakhulu kwenkonzo. Ngaphezu kokusetshenziswa njengento yokugoqa, iLinbay Machinery ivame ukusebenzisa le nto ukusika i-blade.
Ngaphezu kwakho konke, ungakhetha izinto ze-roller ngokuya ngezidingo zephrofayili yakho kanye nesabelomali sokutshalwa kwezimali. I-Linbay Machinery izohlala ikunikeza ikhambi elingcono kakhulu lezidingo zakho ezithile, ukuze ukwazi ukuthenga umshini wokwakha ama-roll owanelisayo kakhulu.
