Ke Kumu Hana O ka Hoolei Mold A me Kona Hana.

I ke kaʻina hana mold, pono e hoʻomaʻamaʻa pinepine ʻia ka ʻāpana hana o ka mold.ʻO ka hoʻomaʻamaʻa ʻana i ka ʻenehana polishing hiki ke hoʻomaikaʻi i ka maikaʻi a me ke ola lawelawe o ka mold a pēlā e hoʻomaikaʻi ai i ka maikaʻi o ka huahana.E hoʻolauna kēia ʻatikala i ka loina hana a me ke kaʻina hana o ka poli polū.

1. Mold polishing ala a me ka hana kumu

Hoʻohana maʻamau ka hoʻoliʻiliʻi ʻana i nā ʻāpana ʻaila, nā huila huluhulu, ke one, a me nā mea ʻē aʻe. .Pono ke ʻano o ka wili ʻana a me ka polishing no ka maikaʻi o ka ʻili kiʻekiʻe.ʻO ka wili a me ka polishing super-fine i hana ʻia i kahi mea hana wili kūikawā.I loko o ka wai polishing i loaʻa i ka abrasive, ua kaomi ʻia i ka ʻili mīkini e hana i ka neʻe rotary kiʻekiʻe.Hiki i ka polishing ke hoʻokō i ka ʻili o Ra0.008μm.

2. ʻO ke kaʻina hana polishing

(1) poni kalakala

Hiki ke hoʻonaniʻia ka mīkini maikaʻi, EDM, wili, a me nā mea'ē aʻe me ka'ōniʻoniʻo poli me ka wikiwiki o ka 35 000 a 40 000 r / min.A laila aia kahi ʻaila pōhaku e wili ai, ʻaila pōhaku ʻaila me ke ʻaila ma ke ʻano he lubricant a i ʻole ka mea hoʻomaha.ʻO ke kauoha o ka hoʻohana ʻana ʻo 180#→240#→320#→400#→600#→800#→1 000#.

(2) Semi-maikaʻi poli

Hoʻohana nui ka semi-finishing i ka sandpaper a me ka ʻaila.ʻO ka helu o ka pepa ʻeleʻele ma ke ʻano:

400#→600#→800#→1000#→1200#→1500#.ʻO ka ʻoiaʻiʻo, hoʻohana ʻo #1500 sandpaper i ke kila kila kūpono no ka paʻakikī (ma luna o 52HRC), a ʻaʻole kūpono i ke kila paʻa mua, no ka mea hiki ke hōʻino i ka ʻili o ke kila paʻa mua a hiki ʻole ke hoʻokō i ka hopena polishing i makemake ʻia.

(3) Ka poni maikai

Hoʻohana nui ka poli maikaʻi i ka paʻi abrasive daimana.Inā wili me ka huila lole poni e hoʻohui i ka pauka abrasive daimana a i ʻole ka paʻi abrasive, ʻo ke kauoha wili maʻamau ʻo 9 μm (1 800 #) → 6 μm (3 000 #) → 3 μm (8 000 #).Hiki ke hoʻohana ʻia ka huila daimana 9 μm a me ka huila lole polishing e wehe i nā kaha lauoho mai ka pepa 1 200# a me 1 50 0#.Hana ʻia ka polishing me ka manaʻo a me ka paʻi daimana ma ke kauoha o 1 μm (14 000 #) → 1/2 μm (60 000 #) → 1/4 μm (100 000 #).

(4) Kaiapuni hana poni

Pono e hoʻokaʻawale ʻia ke kaʻina hana polishing ma nā wahi hana ʻelua, ʻo ia hoʻi, ka hoʻokaʻawale ʻana i ka wahi hana wili ʻala a me ka wahi hana polishing maikaʻi, a pono e mālama ʻia e hoʻomaʻemaʻe i nā ʻāpana one i koe ma luna o ka ʻili o ka mea hana ma mua. kaʻina hana.

ʻO ka mea maʻamau, ma hope o ka poli ʻana me ka pōhaku aila i 1200 # sandpaper, pono e hoʻomaʻemaʻe ʻia ka mea hana e hoʻomaʻemaʻe ʻole me ka lepo ʻole, e hōʻoia ana ʻaʻohe lepo lepo i ka lewa e pili i ka ʻili o ka lepo.ʻO nā koi pololei ma luna o 1 μm (me 1 μm) hiki ke hana ʻia i loko o kahi keʻena polishing maʻemaʻe.No ka poni pololei loa, pono ia ma kahi ma'ema'e loa, no ka mea, hiki i ka lepo, ka uahi, ka dandruff a me nā kulu wai ke ʻoki i nā ʻaoʻao poni kiʻekiʻe.

Ma hope o ka pau ʻana o ka hana polishing, pono e pale ʻia ka ʻili o ka mea hana mai ka lepo.I ka pau ʻana o ke kaʻina hana polishing, pono e wehe pono ʻia nā abrasives a me nā lubricants e hōʻoia i ka maʻemaʻe o ka ʻili o ka mea hana, a laila e hoʻopuʻi ʻia kahi papa o ka uhi anti-rust ma luna o ka ʻili o ka mea hana.
