Iirolazezona nyathelo zibalulekileyo kwiinkqubo yokwenza ukugoba okubandayoNgoko ke, izinto ezikhethiweyo kwi-roller nazo zibalulekile ekugwebeni umgangatho we-umatshini wokwakha i-rollUkukhethwa kwezinto ezahlukeneyo zeerola kuya kubangela umahluko omkhulu kumgangatho weprofayili kunye neendleko zemveliso. Kwimarike yoomatshini bokwenza iirola baseTshayina, izinto zeerola zihlala zahlulwe zibe ziintlobo ezilandelayo: intsimbi engama-45, intsimbi engama-45 efakwe ngombane ene-Cr, i-GCr15, i-Cr12, i-Cr12MOV, njl.
Abavelisi abaninzi baya kutshintsha iirola zibe yintsimbi ukuze bonge iindleko. Abathengi kufuneka bahlukanise ngononophelo xa uthenga oomatshini. Ngenxa yokwahluka kwesinyithi kwizinto zeekhemikhali C, Cr, MO, V, njl. zeentlobo ezahlukeneyo zezinto ezikhankanyiweyo apha ngasentla, ukusebenza kwenkqubo kunye nexabiso zahlukile kakhulu, ngoko ke ukusetyenziswa kwimveliso nako kwahlukile. Kwiikhoyili eziqhelekileyo ezinamandla okuvelisa angaphantsi kwe-330Mpa kunye nobubanzi bobukhulu obungaphantsi kwe-1.5mm, njengeeshiti ezigoqwe ngobushushu, amaphepha agoqwe ngobushushu, i-PPGI, intsimbi egayiweyo, intsimbi engama-45 okanye intsimbi engama-45 echromed zinokuhlangabezana neemfuno. Ukuze kuthintelwe iirola ukuba zingagqwali kwaye kwandiswe ubomi benkonzo yeerola, iLinbay Machinery isebenzisa inkqubo ye-chrome plating kuzo zonke iirola zentsimbi ezingama-45 (ubukhulu be-chrome plating yi-0.05mm), kwaye ubunzima emva konyango lobushushu bunokufikelela kwi-58-62HRC, obufana nobunzima beCr12 kunye ne-GCr15. Ngelixa kunciphisa iindleko, kufikelela kumgangatho olungileyo ngaxeshanye. Ukuba ufuna ukuvelisa iikhoyili ezinamandla aphezulu ezinamandla okuvelisa ngaphezulu kwe-350Mpa okanye iikhoyili zentsimbi engagqwaliyo, iLinbay Machinery iya kukhetha i-GCr15 okanye i-Cr12 njengezinto ezisetyenziswa kwiirola, ezibiza kakhulu. Ezi zinto zimbini zinokumelana nokuguguleka okuphezulu, uzinzo lobushushu kunye namandla okucinezela, ukusebenza kakuhle kakhulu. Phakathi kwazo, icandelo le-Cr12 lilingana ne-American Standard D3. Ukongeza ekusetyenzisweni njengezinto zokuqengqeleka, i-Cr12 ikwasetyenziswa njengezinto zokubhoboza, zokudaya, kunye nezokufaka. Ezona zinto zisemgangathweni ophezulu zeerola yi-Cr12Mov okanye i-Japanese standard SKD11 okanye i-American standard D2, ebiza kakhulu xa ithelekiswa nezinye, inokumelana nokuguguleka okuphezulu kwaye inobomi obude benkonzo. Ukongeza ekusetyenzisweni njengezinto zerola, iLinbay Machinery idla ngokusebenzisa ezi zinto ukusika iblade.
Ngaphezu kwako konke, ungakhetha izinto zerola ngokweemfuno zeprofayili yakho kunye nohlahlo-lwabiwo mali lotyalo-mali. I-Linbay Machinery iya kuhlala ikunika isisombululo esifanelekileyo kwiimfuno zakho ezithile, ukuze ukwazi ukuthenga umatshini wokwenza irola owanelisayo.
