Hlau stamping qhov chaw yog dav siv nyob rau hauv ntau yam ntawm peb lub neej, nrog rau qee yam khoom siv hluav taws xob, nws pib qhov chaw, cov khoom siv kho kom zoo nkauj, thiab lwm yam. Lub hardness ntawm hlau stamping qhov chaw yog kuaj nrog Rockwell hardness tester. Cov khoom me me uas muaj cov duab nyuaj tuaj yeem siv los ntsuas qhov chaw me me uas tsis tuaj yeem sim nrog cov rooj zaum zoo li Rockwell hardness testers. Cia peb paub tias qhov tseeb qhov tseeb ntawm cov hlau stamped qhov chaw yog dab tsi.
Qhov tseeb qhov tseeb ntawm cov hlau stamping qhov chaw yog hais txog qhov sib txawv ntawm qhov loj me ntawm cov khoom stamped thiab qhov siv loj. Qhov sib txawv me me, qhov siab dua qhov tseeb ntawm cov hlau stamped qhov chaw. Cov yam tseem ceeb uas ua rau muaj qhov tsis zoo ntawm cov hlau stamped qhov chaw yog: qhov tseeb ntawm kev tsim khoom convex thiab concave tuag; qhov sib txawv ntawm convex thiab concave tuag; elastic rov qab ntawm cov khoom tom qab stamping; random yam hauv cov txheej txheem ntau lawm, xws li qhov chaw tsis raug, cov khoom tsis ruaj khov, thiab lwm yam.
Qhov saum npoo zoo ntawm cov hlau stamped qhov chaw yuav tsum tsis txhob siab tshaj qhov zoo ntawm cov khoom siv raw, txwv tsis pub, kom ua tiav nws, yuav tsum tau ua ntxiv tom qab ua tiav, nce tus nqi ntawm cov khoom.
Qhov tseeb qhov tseeb ntawm cov hlau stamping feem ntau tuaj yeem muab faib ua ob pawg: qib precision thiab qib pa. Qib precision yog qhov precision uas tuaj yeem ua tiav technically tiav hauv cov txheej txheem stamping, thaum cov paib theem yog qhov precision uas tuaj yeem ua tiav los ntawm kev lag luam ntau dua. Thaum cov pwm tsim precision siab, sab nraud qhov tseeb ntawm cov hlau stamping qhov chaw tuaj yeem ncav cuag ITl 0 qib, thiab qhov loj me tuaj yeem ncav cuag IT9 qib.
