Cov ntaub ntawv me me: Qhov loj me me: Vim tias cov cuab yeej tsim yog cov cuab yeej tsis zoo, yog li feem ntau raws li tus neeg siv khoom kos duab lossis daim ntawv qhia workpiece los tsim thiab kev cai
Txheej txheem
Cov khoom siv hardness: HB200 ~ 250
Raws li pom nyob rau hauv daim duab, cov kauj ruam thiab sab hauv thiab sab nrauv arc ntawm ib txheej ntawm cov cuab yeej tuav qhov yog ua tiav nyob rau hauv ib lub sij hawm, uas yog ntau tshaj 10 lub sij hawm ntawm efficiency ntawm ib tug zoo tib yam laum ntsis.
