1. Xaiv cov twj paj nruag kuaj
Rockwell Hardness Tester (HRC): Tsim nyog rau kev sim lub hardness ntawm quenched steel (piv txwv li kev kho mob ua ntej kev kho cua sov tuaj yeem ncav cuag HRC55 ~ 62).
LeeB Hardness Tester: Portable rau on -} Cov Qauv Xeem Ntawv (}}
Brinell Hardness Tester (HBW): Rau kev sim loj - Qhov loj me tom qab tempering, indentation diam yuav tsum nyob hauv thaj tsam 2.5 ~ 3.0mm.
2. Kev ua haujlwm cov txheej txheem
Kev kho deg: Tshem tawm cov nplai, Decarburized txheej, thiab burrs kom ntseeg tau tias qhov chaw kuaj kom zoo.
Kev Ntsuas Tes Taw Qhia: Ntsuas tsawg kawg 3 cov ntsiab lus ntawm txhua qhov chaw, thiab tsis muaj kev sib cais (piv txwv li, hrc hloov dua tshiab tshaj lossis sib npaug rau ± 2).
Kev ntsuas hluav taws xob yuav tsum muaj: lub chaw ua haujlwm nyuaj yuav tsum tau ntsuas tsis tu ncua kom tsis txhob muaj kev sib tw lossis cov cuam tshuam.
3. Cov xwm txheej tshwj xeeb
Kuaj qhov tseem ceeb ntawm tuab -} cov hlua hluav taws xob: Siv tus ultrasonic tuab cov tib neeg (xws li LS211) rau kev ua haujlwm; Cov tub ntxhais ua lub siab yuav yog 5-10 HRC qis dua saum npoo.
Nto hardened txheej: vickers hardness txujci (HV) rau txheej {{0} {{ale} kev ntsuas txheej; Tus nqi tseem ceeb feem ntau yog 550hv.
