A yau ina so in gabatar muku da wani na'urar gwajin taurin Rockwell na zahiri tare da ƙaramin ƙarfin gwaji fiye da na Rockwell hardness tester:

Superficial Rockwell hardness tester wani nau'in gwajin taurin Rockwell ne.Yana amfani da ƙaramin ƙarfin gwaji.Lokacin gwada wasu ƙananan kayan aiki na bakin ciki, yin amfani da gwajin taurin Rockwell zai haifar da ƙimar ma'auni mara kyau.Za mu iya amfani da Superficial Rockwell hardness tester.Hakanan za'a iya amfani da ma'aunin taurin don auna kayan aiki tare da taurare mai tauri.
Ka'idodin gwajin sa daidai yake da na Rockwell hardness tester.Bambancin shine ƙarfin gwajin farko shine 3KG, yayin da ƙarfin gwajin farko na ma'aunin taurin Rockwell na yau da kullun shine 10KG.

Superficial Rockwell hardness tester matakin ƙarfin gwajin: 15KG, 30KG, 45KG

Mai shigar da aka yi amfani da shi a cikin Superficial Rockwell hardness tester ya yi daidai da na'urar gwajin taurin Rockwell:

1. 120 dalamar lu'u-lu'u mazugi

2. 1.5875 karfe ball indenter

RockwellMa'aunin ma'aunin taurin gwajin:

HR15N, HR30N, HR45N, HR15T, HR30T, HR45T

(Ana auna ma'aunin N ta hanyar indenter ɗin lu'u-lu'u, kuma ma'aunin T ana auna ta ta hanyar indenter ɗin ƙwallon ƙarfe)

An bayyana taurinkamar: darajar taurin da ma'aunin Rockwell, misali: 70HR150T

15T yana nufin mai shigar da ƙwallon karfe tare da jimlar ƙarfin gwaji na 147.1N (15 kgf) da indenter na 1.5875

Dangane da cha na samaracteristics, Superficial Rockwell yana da fa'idodi masu zuwa:

1. Tunda yana da biyushugabannin matsa lamba, ya dace da kayan ƙarfe mai laushi da wuya.

2. Ƙarfin gwaji shine smfiye da na Rockwell hardness tester, kuma Lalacewar da ke tattare da kayan aiki kadan ne.

3. Karamin gwajin ƙarfie na iya maye gurbin ɗan gwajin taurin Vickers, wanda yake da ƙarancin tattalin arziki da araha.

4. A gwajin tsari ne azumi da ƙãre workpiece za a iya gano nagarta sosai.
