Yadda za a duba idan na'urar gwajin taurin kai tana aiki yadda ya kamata?

Gargaɗi ga masu gwajin tauri:
Baya ga taka tsantsan na musamman lokacin amfani da na'urorin gwaji daban-daban na tauri, akwai wasu matsaloli na yau da kullun da ya kamata a kula da su, waɗanda aka jera a ƙasa:
1. Mai gwajin taurin kanta zai samar da nau'ikan kurakurai guda biyu: ɗaya shine kuskuren da nakasa da motsin sassansa suka haifar; ɗayan kuma shine kuskuren da sigar taurin ta haifar ta wuce ƙa'idar da aka ƙayyade. Ga kuskure na biyu, ana buƙatar a daidaita mai gwajin taurin da tubalin da aka saba kafin a auna. Don sakamakon daidaitawa na mai gwajin taurin Rockwell, bambancin ya cancanta a cikin ±1. Ana iya ba da ƙimar gyara don ƙimar da ta dace tare da bambanci a cikin ±2. Lokacin da bambancin ya fita daga kewayon ±2, yana da mahimmanci a daidaita da gyara mai gwajin taurin ko a canza zuwa wasu hanyoyin gwajin taurin.
Kowace ma'aunin taurin Rockwell tana da takamaiman ma'auni na aikace-aikacenta, wanda ya kamata a zaɓa daidai bisa ga ƙa'idodi. Misali, lokacin da taurin ya fi HRB100, ya kamata a yi amfani da ma'aunin HRC don gwaji; lokacin da taurin ya fi ƙasa da HRC20, ya kamata a yi amfani da ma'aunin HRB don gwaji. Saboda daidaito da jin daɗin mai gwajin taurin ba su da kyau lokacin da aka wuce iyakar gwajin, kuma ƙimar taurin ba daidai ba ce, bai dace da amfani ba. Sauran hanyoyin gwajin taurin suma suna da ƙa'idodin daidaitawa masu dacewa. Ba za a iya amfani da ma'aunin tubalin da aka yi amfani da shi don daidaita mai gwajin taurin a ɓangarorin biyu ba, saboda taurin gefen da na baya ba lallai bane iri ɗaya ne. Gabaɗaya an ƙayyade cewa ma'aunin tubalin yana aiki cikin shekara guda daga ranar daidaitawa.
2. Lokacin maye gurbin indenter ko anvil, a kula da tsaftace sassan da aka haɗa. Bayan an canza shi, a gwada shi sau da yawa da samfurin ƙarfe na wani takamaiman tauri har sai ƙimar tauri da aka samu sau biyu a jere ta zama iri ɗaya. Manufar ita ce a sanya indenter ko anvil da ɓangaren da aka haɗa na injin gwaji a matse sosai kuma suna cikin kyakkyawan hulɗa, don kada ya shafi daidaiton sakamakon gwajin.
3. Bayan an daidaita na'urar gwajin tauri, lokacin da aka fara auna tauri, ba a amfani da wurin gwaji na farko ba. Saboda tsoron rashin mu'amala tsakanin samfurin da anvil, ƙimar da aka auna ba daidai ba ce. Bayan an gwada wurin farko kuma na'urar gwajin tauri tana cikin yanayin aikin da aka saba, ana gwada samfurin a hukumance kuma ana rubuta ƙimar tauri da aka auna.
4. Idan gwajin ya ba da dama, galibi zaɓi sassa daban-daban don gwada aƙalla ƙimar tauri uku, ɗauki matsakaicin ƙimar, sannan ɗauki matsakaicin ƙimar azaman ƙimar tauri na gwajin.
5. Ga kayan gwaji masu siffofi masu rikitarwa, ya kamata a yi amfani da kushin siffofi masu dacewa, kuma ana iya gwada su bayan an gyara su. Galibi ana sanya kayan gwaji masu zagaye a cikin rami mai siffar V don gwaji.
6. Kafin a ɗora kaya, a duba ko an sanya maƙallin ɗaukar kaya a wurin sauke kaya. Lokacin ɗaukar kaya, aikin ya kamata ya kasance mai sauƙi kuma mai ɗorewa, kuma kada a yi amfani da ƙarfi da yawa. Bayan an ɗora kaya, ya kamata a sanya maƙallin ɗaukar kaya a wurin sauke kaya, don hana kayan aikin ɗaukar kaya na dogon lokaci, wanda hakan zai haifar da lalacewar filastik da kuma shafar daidaiton aunawa.
Vickers, Taurin Rockwell
Tauri: Ikon abu ne na tsayayya da lalacewar filastik na gida, kuma galibi ana auna shi ta hanyar shigar da shi cikin rami.
Lura: Ba za a iya kwatanta ƙimar taurin kai tsaye da juna ba, kuma ana iya canza ta ne kawai ta hanyar teburin kwatanta taurin.
