Roolayaashawaa tallaabada ugu muhiimsan ee guushahabka sameynta qabow-qabowSidaa darteed, walaxda loo xushay duubista ayaa sidoo kale ah qodob muhiim ah oo lagu qiimeeyo tayadamashiinka duuban sameyntaXulashada agabka kala duwan ee duubista waxay sababi doontaa farqi weyn oo ku yimaada tayada muuqaalka iyo qiimaha wax soo saarka. Suuqa mashiinka sameynta duubista ee Shiinaha, walxaha duubista waxaa badanaa loo qaybiyaa noocyada soo socda: 45 bir, 45 bir oo elektaroonik ah oo leh Cr, GCr15, Cr12, Cr12MOV, iwm.
Soo-saareyaal badan ayaa sidoo kale roogaga u beddeli doona bir la shubay si loo badbaadiyo kharashka. Iibsadayaashu waxay u baahan yihiin inay si taxaddar leh u kala saaraan marka aad iibsanayso mashiinno. Sababtoo ah waxa ku jira birta kala duwan ee walxaha kiimikada C, Cr, MO, V, iwm. ee noocyada kala duwan ee agabka kor ku xusan, waxqabadka habka iyo qiimaha aad ayuu u kala duwan yahay, sidaa darteed codsiga wax soo saarka sidoo kale waa ka duwan yahay. Roogaga caadiga ah ee leh xoog wax soo saar oo ka yar 330Mpa iyo dhumucdiisuna ka yar tahay 1.5mm, sida xaashiyaha kulul ee la duubay, xaashiyaha qabow ee la duubay, PPGI, birta galvanized, 45 bir ama 45 bir ah oo chromed ah ayaa buuxin kara shuruudaha. Si looga hortago roogaga inay miridhaan oo ay u dheereeyaan cimriga adeegga ee roogaga, Linbay Machinery waxay marisaa habka dahaadhka chrome dhammaan 45 roogaga birta ah (dhumucda dahaadhka chrome waa 0.05mm), adkaanta ka dib daaweynta kulaylka waxay gaari kartaa 58-62HRC, taas oo qiyaastii la mid ah adkaanta Cr12 iyo GCr15. Iyadoo la dhimayo kharashyada, waxay heshaa tayo wanaagsan isla waqtigaas. Haddii aad rabto inaad soo saarto gariirado xoog badan oo leh awood wax soo saar oo ka weyn 350Mpa ama gariirado bir ah oo aan miridh lahayn, Linbay Machinery waxay dooran doontaa GCr15 ama Cr12 inay yihiin agabka loogu talagalay duubayaasha, kuwaas oo ka qaalisan. Labadan agab waxay leeyihiin iska caabin sare oo xirasho, xasillooni kul iyo xoog cadaadis, waxqabad guud oo heer sare ah. Waxaa ka mid ah, qaybta Cr12 waxay la mid tahay Heerka Mareykanka D3. Marka laga soo tago in loo isticmaalo sidii walxo duuban, Cr12 sidoo kale waxaa badanaa loo isticmaalaa sida qalab lagu dhejiyo, lagu dhejiyo, iyo qalab lagu geliyo. Agabka ugu tayada sarreeya ee duubayaasha waa Cr12Mov ama heerka Japan SKD11 ama heerka Mareykanka D2, kaas oo aad qaali u ah marka la barbar dhigo kuwa kale, wuxuu leeyahay iska caabin sare oo xirasho wuxuuna leeyahay cimriga ugu dheer ee adeegga. Marka laga soo tago in loo isticmaalo sidii walxo duuban, Linbay Machinery badanaa waxay u isticmaashaa agabkan jarista daab.
Intaa waxaa dheer, waxaad dooran kartaa agabka duubista iyadoo loo eegayo shuruudahaaga gaarka ah iyo miisaaniyadda maalgashiga. Linbay Machinery waxay had iyo jeer ku siin doontaa xalka ugu fiican ee baahiyahaaga gaarka ah, si aad u iibsato mashiin sameeya duubis oo aad u qancisa.
