Zodzigudubuzandi gawo lofunikira kwambiri mukuzizira-kupindika kupanga ndondomeko. Choncho, zinthu zomwe zasankhidwa kuti zikhale zodzigudubuza ndizofunikanso kwambiri poweruza ubwino wa amakina opangira mpukutu. Kusankhidwa kwa zida zosiyanasiyana zodzigudubuza kumabweretsa kusiyana kwakukulu pamtundu wa mbiri komanso pamtengo wopangira. Mu msika waku China wodzigudubuza, zinthu zodzigudubuza nthawi zambiri zimagawidwa m'mitundu iyi: zitsulo 45, zitsulo 45 zopangidwa ndi Cr, GCr15, Cr12, Cr12MOV, ndi zina zambiri.
Opanga ambiri asinthanso zodzigudubuza kuti aziponya chitsulo kuti apulumutse ndalama. Ogula amafunika kusiyanitsa mosamala mukagula makina. Chifukwa cha zitsulo zosiyanasiyana zomwe zili muzinthu zamagetsi C, Cr, MO, V, ndi zina zomwe zatchulidwa pamwambapa mitundu ingapo ya zipangizo, njira yogwirira ntchito ndi mtengo ndizosiyana kwambiri, choncho ntchito yopanga ndi yosiyana. Pakuti koyilo wamba ndi mphamvu zokolola zosakwana 330Mpa ndi makulidwe osiyanasiyana zosakwana 1.5mm, monga mapepala otentha adagulung'undisa, mapepala ozizira adagulung'undisa, PPGI, kanasonkhezereka zitsulo, 45 zitsulo kapena 45 zitsulo chromed akhoza kukwaniritsa zofunika. Pofuna kupewa odzigudubuza kuti dzimbiri ndi kutalikitsa moyo utumiki odzigudubuza, Linbay Machinery ntchito chrome plating ndondomeko onse 45 zitsulo odzigudubuza (chrome plating makulidwe ndi 0.05mm), ndi kuuma pambuyo kutentha mankhwala akhoza kufika 58-62HRC, amene ndizofanana ndi kuuma kwa Cr12 ndi GCr15. Kuchepetsa mtengo, kumakhala bwino nthawi yomweyo. Ngati mukufuna kupanga makoyilo amphamvu kwambiri okhala ndi mphamvu zokolola zokulirapo kuposa 350Mpa kapena zitsulo zosapanga dzimbiri, Linbay Machinery isankha GCr15 kapena Cr12 ngati zinthu zodzigudubuza, zomwe ndi zokwera mtengo. Zida ziwirizi zimakhala ndi kukana kwapamwamba, kukhazikika kwamafuta ndi mphamvu zopondereza, magwiridwe antchito abwino kwambiri. Mwa iwo, gawo la Cr12 ndi lofanana ndi American Standard D3. Kuphatikiza pa kugwiritsidwa ntchito ngati mpukutu, Cr12 imagwiritsidwanso ntchito ngati nkhonya, kufa, ndikuyika zinthu. Zodzigudubuza zapamwamba kwambiri ndi Cr12Mov kapena Japanese standard SKD11 kapena American standard D2, zomwe ndizokwera mtengo kwambiri poyerekeza ndi zina, zimakhala zolimba kwambiri ndipo zimakhala ndi moyo wautali kwambiri. Kuphatikiza pa kugwiritsidwa ntchito ngati zodzigudubuza, Linbay Machinery nthawi zambiri amagwiritsa ntchito izi podula tsamba.
Koposa zonse, mutha kusankha zinthu zodzigudubuza malinga ndi zomwe mukufuna pa mbiri yanu komanso bajeti yoyika ndalama. Linbay Machinery nthawi zonse ikupatsani yankho labwino kwambiri pazomwe mukufuna, kuti mutha kugula makina opangira mpukutu wokhutiritsa kwambiri.
