He aha nā mea e mālama ai i ke koho ʻana i nā Mills End

I mea e hoʻolōʻihi ai i ke ola o ka ʻōpala, ʻoi aku ka paʻakikī o ka mea e ʻoki ʻia.No laila, hāʻawi ʻia nā koi kiʻekiʻe no ke ola o ka mea hana a me ka hana ʻana i ka pono i ka mīkini wikiwiki kiʻekiʻe o nā mea paʻakikī kiʻekiʻe.ʻO ka maʻamau, hiki iā mākou ke koho i nā wili hope mai ʻekolu mau wahi:

1. E koho i ke 'ano o ka mea paahana e like me ke 'ano a me ka pa'akikī o ka mea hana e hana 'ia.No ka laʻana, i ka hana ʻana i ke kila kalapona a me nā mea hana ʻē aʻe me ka paʻakikī ma lalo o HRC40, hiki ke koho ʻia ka uhi MIRACLE40 mai Comprehensive Materials Company.I ka hana ʻana i ke kila kila S, ke kila mea hana a me nā mea hana ʻē aʻe me ka paʻakikī e pili ana i ka HRC50, hiki ke koho ʻia ka uhi MIRACLE.I ka hanaʻana i nā mea hana me ka paʻakikī kiʻekiʻe, hiki iāʻoe ke koho i keʻano o ka mea hana, ka mea carbide, a me ka uhiʻana,ʻo ia mau mea a pau he MIRACLE paʻa no ka mīkini paʻakikī kiʻekiʻe o nā mea paʻakikī.

2. E koho i ke ʻano o ka ʻāʻī ʻoki wili hope e like me ke ʻano o ka mea hana e hana ʻia.Hoʻokaʻawaleʻia keʻano o ka'ā'ī o ka wili hope i keʻano maʻamau, keʻano'ā'ī lōʻihi a me keʻano'ā'ī tapered, hiki ke kohoʻia e like me ka hana a me keʻano o ka mea hana.Hiki ke hoʻohana ʻia ke ʻano ʻāʻī lōʻihi a me ke ʻano ʻāʻī tapered no ka ʻeli hohonu ʻana, a pono e noʻonoʻo ʻia ke kihi interference i ke koho ʻana ma waena o nā mea ʻelua.I ka manawa like, ke hoʻohālikelike ʻia me ke ʻano ʻāʻī lōʻihi, ʻo ka mīkini hope ʻāʻī tapered he rigidity kiʻekiʻe, hiki ke hoʻomaikaʻi i nā kūlana ʻoki a hoʻokō i ka pololei machining.Pono e koho ʻia ka mīkini ʻāʻī lipi e like me ka hiki.

3. E koho i na wili hope me ka pololei o ke poo poepoe e like me ka pololei machining.ʻO ka pololei arc o nā wili hope maʻamau maʻamau ± 10 μm, akā aia kekahi mau wili hope me ± 5 μm, hiki ke koho ʻia i ka wā e hana ai.
