Lub tshuab luam yeeb dov suav nrog plaub qhov tseem ceeb: kev pub mis, sib sau, txiav thiab tswj qhov hnyav, peb cov khoom siv feem ntau yog siv rau hauv qhov txiav, "PASSION" tuaj yeem muab cov luam yeeb zoo tshaj plaws thiab ntim cov riam muaj. Peb paub zoo txog cov ntaub ntawv zoo tshaj plaws thiab cov khoom tiav uas xav tau los ua cov khoom lag luam luam yeeb zoo tshaj plaws. Los ntawm tungsten carbides mus rau qib qis xws li hmoov hlau, kev kub ceev steel, cuab yeej hlau thiab stainless hlau, peb tuaj yeem pab koj tsim ntau dua, sai dua. Peb muab cov hniav nram qab no rau kev txiav luam yeeb, luam yeeb lim thiab luam yeeb: tungsten carbide ncig riam, KTH 420 hli slitting riam rau luam yeeb, 124 hli tipping riam rau protos, tipping hniav thiab lwm yam, Peb cov riam tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov luam yeeb. ua tshuab, zoo li protos, passim, Hauni thiab lwm yam. Nrog rau siab hardness thiab du thiab ntse txiav ntug, cov riam yeej ib txwm txiav luam yeeb, luam yeeb lim thiab luam yeeb yam tsis muaj kev vau, Tib lub sijhawm, peb tuaj yeem muab daim iav saum npoo kho thiab txheej txheej rau cov hniav no, uas tuaj yeem txo cov sijhawm kho thiab kho kom tsawg.
