Ka Mīkini CNC ma POM
ʻO nā palakiko kekahi mea maʻamau i hoʻohana ʻia i ka huli ʻana CNC no ka mea loaʻa lākou i nā koho like ʻole, he ʻano pipiʻi ke kumu kūʻai, a he wikiwiki ka manawa hana. ʻO nā palakiko i hoʻohana pinepine ʻia e komo pū me ABS, acrylic, polycarbonate a me nylon.
Wehewehena POM (Polyoxymethylene)
ʻO POM, i ʻike ʻia hoʻi ʻo acetal a i ʻole Delrin, he mea thermoplastic me nā waiwai semi-crystalline. Mahalo nui ʻia no kona ikaika kūikawā, ʻoʻoleʻa a me nā waiwai haʻahaʻa haʻahaʻa. Hoʻohana pinepine ʻia ʻo POM i nā noi e koi ana i ka pololei a me nā ʻāpana haʻahaʻa haʻahaʻa.
Noi
ʻO POM, i ʻike ʻia hoʻi ʻo acetal a i ʻole Delrin, he mea thermoplastic versatile i hoʻohana ʻia i nā ʻano hana like ʻole. ʻO kona mau waiwai kūikawā e kūpono ai no ka hana ʻana i nā kia a me nā bearings i nā ʻōnaehana mechanical. Loaʻa pū nā ʻāpana kaʻa, e like me nā ʻāpana ʻōnaehana wahie a me ke kāhiko o loko, mai ka lōʻihi a me ke kūpaʻa o POM. Eia kekahi, ʻo nā waiwai insulating uila maikaʻi loa o POM e kūpono ai no ka hoʻohana ʻana i nā mea hoʻohui uila. ʻO ka hope loa, ʻo ka ikaika a me ke ola lōʻihi o POM e lilo ia i koho makemake ʻia no ka hana ʻana i nā waiwai mea kūʻai aku e like me nā zippers, nā mea pāʻani a me nā lako kīhini.
Nā ikaika
He ikaika kupaianaha ka mea a hiki ke kū i nā ikaika mīkini nui. Hāʻawi ia i ka neʻe mālie me ka liʻiliʻi o ka friction a kūpaʻa i ka ʻaʻahu. Mālama ia i kona ʻano a me nā ana i nā kūlana āpau, e hōʻoiaʻiʻo ana i ke kūpaʻa. Eia kekahi, kūpaʻa ia i nā hopena o nā kemika a hiki ke kū i ka hōʻike ʻana i nā mea like ʻole me ka ʻole o ka hōʻino ʻia.
Nā nāwaliwali
He palena ko ka pale ʻana o ka mea i ka kukuna UV a no laila he maʻalahi ia i ka hōʻino ʻia i ka wā e hoʻolōʻihi ʻia ai i ka lā. Eia kekahi, he maʻalahi ia i nā māwae koʻikoʻi ma lalo o kekahi mau kūlana.

ʻIke ʻepekema kaulana e pili ana iā POM
ʻO POM (Polyoxymethylene), i ʻike ʻia hoʻi ʻo acetal, he plastic ʻenekinia hana kiʻekiʻe. He thermoplastic semi-crystalline ia e hāʻawi ana i ka ikaika mechanical maikaʻi loa, ka paʻakikī, a me ke kūpaʻa dimensional. Hoʻohana pinepine ʻia ka POM i nā ʻāpana kikoʻī, e like me nā kia, nā bearings, a me nā ʻāpana kaʻa.
He haʻahaʻa ka coefficient o ka friction o POM, kahi e kūpono ai no nā noi e pono ai ka haʻahaʻa o ka ʻaʻahu a me ka friction. Loaʻa iā ia ke kūpaʻa maikaʻi i nā kemika, nā mea hoʻoheheʻe, a me nā wahie, e kūpono ai no nā noi ma nā ʻoihana kaʻa a me nā kemika. Loaʻa iā POM nā waiwai insulation uila maikaʻi a hiki ke kū i nā mahana kiʻekiʻe.
Loaʻa ka POM i ʻelua ʻano nui: homopolymer a me copolymer. Hāʻawi ka Homopolymer POM i ka ikaika mechanical kiʻekiʻe a me ka paʻakikī, ʻoiai ʻo ka copolymer POM e hāʻawi i ka pale maikaʻi ʻana i ka hoʻohaʻahaʻa thermal a me ka hoʻouka kemika.
