Amarolaziyisinyathelo esibucayi kakhulu kuinqubo yokwakha egobayo.Ngakho-ke, izinto ezikhethiwe ze-roller nazo ziyisici esibalulekile ekwahluleleni ikhwalithi yeumshini wokwenza roll.Ukukhethwa kwezinto ezihlukene zamarola kuzodala umehluko omkhulu ngekhwalithi yephrofayili kanye nezindleko zokukhiqiza.Emakethe yomshini wokwenza umqulu wamaShayina, izinto ezisetshenziswayo zamarola zivame ukuhlukaniswa zibe izinhlobo ezilandelayo: insimbi engama-45, insimbi engama-45 efakwe i-Cr, GCr15, Cr12, Cr12MOV, njll.
Abakhiqizi abaningi bazophinde bashintshe ama-roller ukuze bafake insimbi ukuze bonge izindleko.Abathengi badinga ukuhlukanisa ngokucophelela lapho uthenga imishini.Ngenxa yokuqukethwe kwensimbi okuhlukile kwezakhi zamakhemikhali C, Cr, MO, V, njll. kwezinhlobo eziningana zezinto ezibalwe ngenhla, ukusebenza kwenqubo kanye nentengo kuhluke kakhulu, ngakho-ke isicelo ekukhiqizeni nakho kuhlukile.Kumakhoyili avamile anamandla esivuno angaphansi kuka-330Mpa kanye nobubanzi obuwugqinsi obungaphansi kuka-1.5mm, njengamashidi agoqelwe ashisayo, amashidi agoqwe abandayo, i-PPGI, insimbi yama-galvanized, 45 steel noma 45 steel chromed angahlangabezana nezidingo.Ukuze uvimbele ama-roller ukuthi angagqwali futhi andise impilo yesevisi yamarola, Imishini ye-Linbay isebenzisa inqubo yokucwenga ye-chrome kuwo wonke ama-roller ensimbi angu-45 (ugqinsi lwe-chrome plating ngu-0.05mm), futhi ubulukhuni ngemva kokwelashwa kokushisa bungafinyelela ku-58-62HRC, okuyinto icishe ifane nobulukhuni be-Cr12 ne-GCr15.Ngenkathi inciphisa izindleko, ithola ikhwalithi enhle ngesikhathi esifanayo.Uma ufuna ukukhiqiza amakhoyili anamandla amakhulu anamandla esivuno angaphezu kuka-350Mpa noma amakhoyili ensimbi engagqwali, i-Linbay Machinery izokhetha i-GCr15 noma i-Cr12 njengempahla yamarola, abiza kakhulu.Lezi zinto ezimbili zinokumelana nokugqoka okuphezulu, ukuzinza okushisayo namandla acindezelayo, ukusebenza okuhle kakhulu okuphelele.Phakathi kwazo, ingxenye ye-Cr12 ilingana ne-American Standard D3.Ngaphezu kokusetshenziswa njengento yokugoqa, i-Cr12 iphinde isetshenziswe njenge-punch, die, kanye nempahla yokufaka.Izinto ezisezingeni eliphezulu kakhulu zamarola yi-Cr12Mov noma i-SKD11 ejwayelekile yaseJapan noma i-D2 ejwayelekile yaseMelika, ebiza kakhulu uma iqhathaniswa nezinye, inokumelana nokugqokwa okuphezulu futhi inokuphila kwesevisi ende kakhulu.Ngaphezu kokusetshenziswa njenge-roller's material, i-Linbay Machinery ivamise ukusebenzisa le nto ukusika i-blade.
Ngaphezu kwakho konke, ungakhetha izinto ze-roller ngokuya ngezidingo zephrofayili yakho kanye nesabelomali sokutshala imali.I-Linbay Machinery izohlala ikunikeza isisombululo esingcono kakhulu sezidingo zakho ezithile, ukuze ukwazi ukuthenga umshini wokwenza umqulu owanelisa kakhulu.
