NM400 / NM 450 xirtaan saxan bir iska caabin ah
NM450 waa saxan xidhid xoog sare leh.
Magacaabidda: N waxaa loogu talagalay iska caabin (nai), M waa xarafka pinyin ee ugu horreeya ee labada xaraf ee Shiinaha ee shiididda (mo),
iyo 450 waxay ka dhigan tahay celceliska engegnaanta Brinell ee saxankan birta ah
Daaweynta kulaylka: heerkulka sare ee heerkulka, deminta + xanaaqa (dejinta iyo xanaaqa)
Codsiga: NM450 saxan bir xiran u adkaysta ayaa si weyn loogu isticmaalaa mashiinnada macdanta, mashiinnada macdanta dhuxusha,
mishiinada ilaalinta deegaanka, mashiinada dhismaha, iwm, iyo sidoo kale inta badan loo isticmaalo sidii-xoog sare
bir qaabdhismeed leh xoog dhalidda ≥850MPa.
Function: Inta badan waa in la bixiyo ilaalinta munaasabadaha ama qaybaha u baahan xirashada caabbinta, si nolosha
Qalabku wuu dheer yahay, wakhtiga dayactirka ee uu sababay dayactirku waa la dhimay, iyo maalgashiga raasumaalka
si isku mid ah ayaa loo dhimay.
Waxqabad: Wax-soo-saarku wuu ka badan yahay 950, xoogga xajintuna waa 1180.
NM450 waxay u dhigantaa heerarka qalaad iyo darajooyinka JFE:NK-EH450/HARDOX450/DILLDUR:450V
