Q: Kodi kupsinjika kwa track kuyenera kuyang'aniridwa kangati?
A: Kuthamanga kwa njanji kuyenera kufufuzidwa nthawi iliyonse yogwira ntchito maola 250 (sabata lililonse kuti ntchito zipitirire), pambuyo poyika gawo latsopano, pamene zinthu zikusintha, komanso nthawi iliyonse yomwe khalidwe losazolowereka la njanji likuwoneka.

Q: Kodi ubwino wopeza zinthu kuchokera ku CQC TRACK ndi wotani?
A: CQC TRACK imapereka mitengo yopikisana (30-50% kuposa OEM), mphamvu yopangira zinthu zolemera yokhala ndi SAE 4140 alloy ndi HRC 58-62 surface hardness, njira zotsekera zinthu zapamwamba kwambiri, chitsimikizo chapamwamba (ISO 6015:2019 yatsimikiziridwa), komanso ukatswiri waukadaulo pa ntchito za SUMITOMO ndi CASE.

Q: Ndi njira ziti zosamalira zomwe zimawonjezera nthawi ya moyo wa chonyamulira chonyamulira?
Yankho: Njira zazikulu zochitira zinthu ndi monga kukonza bwino kupsinjika kwa njira, kuyang'ana nthawi zonse momwe chisindikizo chilili komanso kuzindikira msanga kutayikira kwa madzi, kuyeretsa nthawi zonse kuti chisindikizo chisamamatire, kupewa kutsuka zisindikizo mwamphamvu, kusintha nthawi yomweyo pakakhala kuti palibe chomwe chawonongeka, komanso njira zosinthira pogwiritsa ntchito makina.

Q: Kodi njira yoyenera yosungira ma roller onyamula katundu ndi iti?
Yankho: Sungani pamalo oyera komanso ouma otetezedwa ku nyengo. Sungani m'mabokosi ake oyambirira ngati alipo. Sinthasinthani nthawi ndi nthawi (miyezi 3-6 iliyonse) kuti musawononge madzi a bearing brine. Tetezani ku kuipitsidwa ndi kuwonongeka.

Buku laukadaulo ili lapangidwira oyang'anira zida zaukadaulo, akatswiri ogula zinthu, ndi ogwira ntchito yokonza zida zolemera. Mafotokozedwe ndi malangizo amachokera ku miyezo yamakampani ndi deta ya opanga yomwe ilipo panthawi yofalitsa. Mayina onse opanga, manambala a magawo, ndi mayina a zitsanzo amagwiritsidwa ntchito pongodziwitsa okha. Nthawi zonse funsani zikalata za zida ndi akatswiri oyenerera aukadaulo kuti mudziwe zomwe zingagwiritsidwe ntchito.
