ʻO ka helu ʻana i ke kumukūʻai mīkini he hana koʻikoʻi.ʻO ka pololei o nā helu kumukūʻai mīkini e pili pono i ka hana, hana a kūʻai aku i nā huahana, ʻo ia ka mea nui.
1. Ke kumu kūʻai waiwai: ke kumukūʻai kūʻai waiwai, ke kumukūʻai o ka halihali waiwai, nā lilo huakaʻi i loaʻa i ka wā o ke kaʻina kūʻai, etc.;
2. Nā koina hana: nā hola hana o kēlā me kēia kaʻina hana, ka hoʻohaʻahaʻa ʻana i nā mea hana, ka wai a me ka uila, nā mea hana, nā mea hana, nā mea ana, nā mea kōkua, etc.
3. Nā lilo hoʻokele: amortization o nā koina paʻa, amortization o nā limahana hoʻokele uku, uku kahua, nā huakaʻi hele, etc.
4.Taxes: ʻauhau aupuni, ʻauhau kūloko;

ʻano helu kumu kūʻai
E helu i ke kumukūʻai hana e like me ka nui, ka nui a me nā koi pono o nā ʻāpana
1. Inā ʻaʻole ʻoi aku ka nui o ka aperture ma mua o 2.5 mau manawa a ʻoi aku ke anawaena ma mua o 25MM, ua helu ʻia e like me ke anawaena drill * 0.5
2. ʻO ka maʻamau o ka hoʻouka ʻana no nā mea maʻamau me kahi ratio hohonu-a-diameter ʻoi aku ma mua o 2.5 e helu ʻia ma muli o ka ratio hohonu-a-diameter * 0.4
3. Lathe hana
Inā ʻaʻole ʻoi aku ka nui o ke anawaena lōʻihi o ka axis optical maʻamau ma mua o 10, ua helu ʻia e like me ka nui o ka mea hana blank * 0.2
Inā ʻoi aku ka nui o ka lākiō hiʻohiʻona ma mua o 10, ʻo ke kumu kūʻai kumu o ke axis optical maʻamau * ratio hiʻohiʻona * 0.15
Inā koi ʻia ka pololei i loko o 0.05MM a i ʻole ka taper e koi ʻia, e helu ʻia e like me ke kumu kumu o ka axis optical maʻamau * 2.
Kaʻina kālā helu helu
1. Pono e hoʻokomo i nā kumukūʻai waiwai, nā koina hana, nā kumukūʻai hoʻemi o nā lako, nā uku limahana, nā uku hoʻokele, nā ʻauhau, etc.
2. ʻO ka hana mua, ʻo ia ke kālailai ʻana i ke ʻano hana, a laila e helu i ka hola hana e like me ke kaʻina hana, e helu i ke kumukūʻai hana kumu a me nā koina ʻē aʻe o kahi hapa hoʻokahi mai ka hola hana.Hoʻohana kekahi ʻāpana i nā kaʻina hana like ʻole, a ʻokoʻa ke kumukūʻai.
3. ʻAʻole paʻa nā hola hana o nā ʻano hana like ʻole.E like me ka paʻakikī o ka mea hana, ka nui a me ka hana o nā mea hana.ʻOiaʻiʻo, pili kēia i ka nui o ka huahana.ʻo ka nui o ka nui, ʻoi aku ka liʻiliʻi o ke kumukūʻai.
ʻIke kumu no ka pololei o ka mīkini ʻana i nā ʻāpana mechanical
ʻO ka pololei o ka mīkini e pili ana i ke kiʻekiʻe o ka nui maoli, ke ʻano, a me ke kūlana o ka ʻili o ka ʻāpana mīkini i kūpono i nā ʻāpana geometric kūpono e koi ʻia e ke kaha kiʻi.ʻO ka mea hoʻohālikelike geometric maikaʻi ka nui awelika;no ka geometry ili, ʻo ia ka pōʻai piha, cylinder, plane, cone a me ka laina pololei, etc.;no ke kūlana like o ka ʻili, aia ka parallelism piha, perpendicularity, coaxiality, symmetry, etc. ʻO ka ʻokoʻa ma waena o nā ʻāpana geometric maoli o ka ʻāpana a me nā ʻāpana geometric kūpono i kapa ʻia ʻo ka machining error.
