Iirolaelona nyathelo libalulekileyo kwiukubanda-goba ukwenza inkqubo. Ngoko ke, izinto ezikhethiweyo kwi-roller nayo yinto ebalulekileyo ekugwebeni umgangatho we-aumatshini wokwenza umqulu. Ukukhethwa kwezinto ezahlukeneyo ze-roller kuya kubangela umahluko omkhulu kumgangatho weprofayili kunye nexabiso lemveliso. Kwimarike yomatshini wokwenza umqulu waseTshayina, izinto eziphathekayo ze-roller zihlala zihlulwe zibe zintlobo ezilandelayo: i-45 yensimbi, i-45 yensimbi ye-electroplated kunye ne-Cr, GCr15, Cr12, Cr12MOV, njl.
Abavelisi abaninzi baya kutshintsha kwakhona iirola ukuphosa intsimbi ukuze kugcinwe iindleko. Abathengi kufuneka bahlule ngononophelo xa uthenga oomatshini. Ngenxa yeziqulatho zetsimbi ezahlukeneyo zezinto zeekhemikhali C, Cr, MO, V, njl. Ezi zikhankanywe ngasentla iintlobo ezininzi zezinto, inkqubo yokusebenza kunye nexabiso zihluke kakhulu, ngoko ke isicelo kwimveliso sikwahluke. Kuba iikhoyili eziqhelekileyo ngamandla isivuno ngaphantsi kwe 330Mpa kunye nobubanzi ububanzi ngaphantsi kwe 1.5mm, ezifana sheets eshushu-eqengqelekayo, sheets abandayo, PPGI, intsimbi galvanized, 45 steel okanye 45 steel chromed unokuhlangabezana neemfuno. Ukuze uthintele iirola ukuba zingagqwala kwaye zandise ubomi benkonzo yeerola, oomatshini baseLinbay bafaka inkqubo yokufakwa kwe-chrome kuzo zonke iirola zentsimbi ezingama-45 (ubukhulu be-chrome plating yi-0.05mm), kwaye ubulukhuni emva konyango lobushushu bunokufikelela kwi-58-62HRC, leyo iphantse yafana nobulukhuni be-Cr12 kunye ne-GCr15. Ngelixa inciphisa iindleko, ifumana umgangatho olungileyo ngaxeshanye. Ukuba ufuna ukuvelisa iikhoyili eziphezulu ezinamandla amakhulu kune-350Mpa okanye iikhoyili zensimbi ezingenasici, i-Linbay Machinery iya kukhetha i-GCr15 okanye i-Cr12 njengempahla yeerola, ezibiza kakhulu. Ezi zinto zimbini zinokumelana nokunxiba okuphezulu, ukuzinza kwe-thermal kunye namandla oxinzelelo, ukusebenza okugqwesileyo jikelele. Phakathi kwabo, icandelo le-Cr12 lilingana ne-American Standard D3. Ukongeza ekusetyenzisweni njengento eqengqelekayo, i-Cr12 ikwasetyenziswa njengepunch, kufa, kunye nokufaka imathiriyeli. Eyona mathiriyeli ikumgangatho ophezulu we-roller yi-Cr12Mov okanye i-SKD11 yaseJapan okanye i-D2 eqhelekileyo yaseMelika, ebiza kakhulu xa ithelekiswa nezinye, inokumelana nokunxiba okuphezulu kwaye inobomi benkonzo ende kakhulu. Ukongeza ekusetyenzisweni njengezinto ze-roller, i-Linbay Machinery idla ngokusebenzisa le nto ukusika i-blade.
Ngaphezu kwakho konke, unokukhetha izinto ze-roller ngokweemfuno zeprofayili yakho kunye nohlahlo lwabiwo-mali lotyalo-mali. ILinbay Machinery iya kusoloko ikunika esona sisombululo silungileyo kwiimfuno zakho ezithile, ukuze ukwazi ukuthenga owona matshini wokwenza umqulu owanelisayo.
