Injin gwajin taurin kai na Universal hakika kayan gwaji ne masu cikakken inganci bisa ga ka'idojin ISO da ASTM, wanda ke ba masu amfani damar gudanar da gwaje-gwajen taurin kai na Rockwell, Vickers da Brinell akan kayan aiki iri ɗaya. Ana gwada na'urar gwajin taurin kai ta duniya bisa ga ƙa'idodin Rockwell, Brinell, da Vickers maimakon amfani da dangantakar juyawa na tsarin taurin kai don samun ƙimar taurin kai da yawa.
Sikeli uku masu tauri da suka dace da auna kayan aiki
Ma'aunin taurin HB Brinell ya dace da auna taurin ƙarfen siminti, ƙarfen da ba na ƙarfe ba, da ƙarfe iri-iri masu annealed da tempered. Bai dace da auna samfura ko kayan aiki waɗanda suka yi tauri, ƙanana, siriri, kuma ba sa barin manyan ramuka a saman.
Sikelin taurin HR Rockwell ya dace da: auna taurin gwajin molds, kashewa, kashewa da kuma daidaita sassan da aka yi wa zafi.
Ma'aunin taurin HV Vickers ya dace da auna taurin samfura da sassa masu ƙananan yankuna da ƙimar taurin kai mai yawa, taurin yadudduka ko rufin da aka shigar bayan an yi amfani da su ta fuskar daban-daban, da kuma taurin kayan da ba su da sirara.
Sabbin nau'ikan gwajin taurin kai na duniya
Bambanta da na'urar gwajin tauri ta gargajiya ta duniya: na'urar gwajin tauri ta zamani ta zamani tana amfani da fasahar firikwensin ƙarfi da tsarin martanin ƙarfi na rufewa don maye gurbin samfurin sarrafa nauyin nauyi, wanda ke sa ma'aunin ya fi sauƙi kuma ƙimar da aka auna ta fi kwanciyar hankali.
