Kev sib txawv ntawm Leeb hardness tester

1. Kev ntsuas hardness ntawm lub tshuab cuab yeej qhia kev tsheb thiab tsheb chassis.
2. Txhim kho cov tshuab lossis cov khoom sib dhos tas mus li.
3. Cov khoom ua haujlwm nrog qhov chaw sim me me xws li pwm kab noj hniav.
4. Kev tshuaj xyuas sai ntawm ntau qhov chaw ntsuas hauv ntau qhov chaw ua haujlwm loj.
5. Kev soj ntsuam tsis tiav ntawm cov hlab ntsha siab, turbine generators thiab lwm yam khoom siv.
6. Cov kab ntau lawm rau cov kabmob thiab lwm yam.
7. Kev faib khoom ntawm cov khoom siv hlau hauv cov khoom siv hlau.
8. Kev tswj zoo ntawm kev kho cua sov workpieces.
9. Yuav tsum muaj cov ntaub ntawv tseem ceeb ntawm cov ntawv xeem.
10. Nws tuaj yeem paub txog kev sib nrig sib hloov ntawm 6 hardnesses (HL, HRB, HRC, HB, HV, HS) thiab kev sib nrig sib hloov ntawm hardness thiab tensile zog.
11. Nws tuaj yeem tso saib qhov ntsuas tus nqi, qhov nruab nrab tus nqi, hnub tim, kev cuam tshuam kev taw qhia, tus naj npawb ntawm cov ntawv xeem, cov ntaub ntawv xeem, hardness system thiab lwm yam ntaub ntawv, thiab cov ntaub ntawv qhia tau nplua nuj.
