Yadda za a bincika idan majinin taurin yana aiki kullum?

Hare-hare masu taurin wuya:
Baya ga taka tsantsan na musamman yayin amfani da na'urorin gwajin tauri iri-iri, akwai wasu matsalolin gama gari waɗanda ya kamata a kula da su, waɗanda aka jera a ƙasa:
1. Mai gwajin taurin kanta zai haifar da kurakurai iri biyu: na daya shi ne kuskuren lalacewa da motsin sassansa;ɗayan kuma shine kuskuren da ke haifar da ma'aunin taurin da ya wuce ƙayyadaddun ƙayyadaddun ma'auni.Don kuskuren na biyu, mai gwajin taurin yana buƙatar a daidaita shi tare da daidaitaccen toshe kafin aunawa.Don sakamakon gyare-gyare na mai gwajin taurin Rockwell, bambancin ya cancanci tsakanin ±1.Ana iya ba da ƙimar gyara don ƙimar tsayayye tare da bambanci tsakanin ± 2.Lokacin da bambanci ya kasance a waje da kewayon ± 2, ya zama dole don daidaitawa da gyara mai gwada tauri ko canza zuwa wasu hanyoyin gwajin taurin.
Kowane sikelin taurin Rockwell yana da ƙayyadaddun ƙayyadaddun aikace-aikace, wanda yakamata a zaɓa daidai gwargwadon ƙa'idodi.Misali, lokacin da taurin ya fi HRB100, yakamata a yi amfani da sikelin HRC don gwaji;lokacin da taurin ya yi ƙasa da HRC20, yakamata a yi amfani da sikelin HRB don gwaji.Saboda daidaito da azancin mai gwajin taurin ba su da kyau lokacin da aka wuce iyakar gwajin, kuma ƙimar taurin ba daidai ba ne, bai dace da amfani ba.Sauran hanyoyin gwajin taurin suma suna da daidaitattun ma'auni.Ba za a iya amfani da ma'auni na ma'aunin da ake amfani da shi don daidaita ma'aunin taurin ba a bangarorin biyu, saboda taurin ma'auni da gefen baya ba lallai ba ne.Gabaɗaya an ƙulla cewa madaidaicin toshe yana aiki a cikin shekara ɗaya daga ranar daidaitawa.
2. Lokacin maye gurbin indentor ko anvil, kula da tsaftace sassan lamba.Bayan canza shi, gwada shi sau da yawa tare da samfurin karfe na wani tauri har sai ƙimar taurin da aka samu sau biyu a jere ya kasance iri ɗaya.Manufar ita ce a sanya mai shiga ko maƙarƙashiya da ɓangaren tuntuɓar na'urar gwajin damtse kuma a cikin kyakkyawar hulɗa, don kada ya shafi daidaiton sakamakon gwajin.
3. Bayan an daidaita ma'aunin taurin, lokacin da aka fara auna taurin, ba a yi amfani da ma'aunin gwaji na farko ba.Don tsoron mummunan hulɗa tsakanin samfurin da maƙarƙashiya, ƙimar da aka auna ba daidai ba ne.Bayan an gwada batu na farko kuma mai gwada taurin yana cikin yanayin aiki na yau da kullun, ana gwada samfurin bisa ƙa'ida kuma ana yin rikodin ƙimar taurin da aka auna.
4. Idan yanki na gwajin ya ba da izini, gabaɗaya zaɓi sassa daban-daban don gwada ƙimar tauri aƙalla uku, ɗauki matsakaicin ƙimar, kuma ɗaukar matsakaicin ƙimar azaman ƙimar taurin yanki.
5. Don gwajin gwaji tare da siffofi masu rikitarwa, ya kamata a yi amfani da pads na siffofi masu dacewa, kuma ana iya gwada su bayan an gyara su.Gabaɗaya yanki na gwajin zagaye ana sanya shi a cikin tsagi mai siffar V don gwaji.
6. Kafin loading, duba ko an sanya kayan aiki a cikin wurin saukewa.Lokacin lodawa, aikin ya kamata ya kasance mai sauƙi kuma a tsaye, kuma kada ku yi amfani da ƙarfi da yawa.Bayan an yi amfani da shi, ya kamata a sanya kayan aiki a cikin matsayi na saukewa, don hana kayan aiki daga kasancewa a cikin kaya na dogon lokaci, haifar da nakasar filastik kuma yana tasiri daidaitattun ma'auni.
