Nā koi pololei no kēlā me kēia kaʻina hana o CNC machining center

Hoʻohana ʻia ka pololei e hōʻike i ka maikaʻi o ka huahana mea hana. He huaʻōlelo kūikawā no ka loiloi ʻana i nā ʻāpana geometric o ka ʻili mīkini. He hōʻailona koʻikoʻi nō ia no ke ana ʻana i ka hana o nā kikowaena mīkini CNC. Ma ka ʻōlelo maʻamau, ana ʻia ka pololei machining e nā pae hoʻomanawanui. ʻO ka haʻahaʻa o ka pae, ʻoi aku ka kiʻekiʻe o ka pololei. ʻO ka huli ʻana, ka wili ʻana, ka hoʻolālā ʻana, ka wili ʻana, ka ʻeli ʻana, a me ka ʻoluʻolu nā ʻano hana maʻamau o nā kikowaena mīkini CNC. No laila he aha ka pololei o ka hana ʻana e pono ai kēia mau kaʻina hana?

1. Huli pololei

a

ʻO ka hoʻohuli ʻana e pili ana i kahi kaʻina hana e ʻoki ai ka mea hana a neʻe ka mea hoʻohuli i ka laina laina a i ʻole curvedly i loko o kahi mokulele e hoʻoponopono i ka ʻili o loko a me waho o ka cylindrical surfaces, nā alo hope, nā ʻili conical, nā ʻili a me nā kaula o ka mea hana.

ʻO ka roughness ili o ka huli ʻana he 1.6-0.8μm.

Pono ka huli ʻana i ka hoʻohana ʻana i ka hohonu ʻoki nui a me ka nui o ka hānai nui e hoʻomaikaʻi i ka pono o ka hoʻohuli ʻana me ka ʻole e hōʻemi i ka wikiwiki ʻoki. Pono ka roughness o ka ʻili he 20-10um.

No ka hoʻohuli ʻana i ka semi-finishing a me ka hoʻopau ʻana, e hoʻāʻo e hoʻohana i ka wikiwiki kiʻekiʻe a me nā meaʻai liʻiliʻi a me ka hohonu o ka ʻoki ʻana, a ʻo ka roughness ʻili he 10-0.16um.

Hoʻohana ʻia nā mea hana hoʻohuli daimana maikaʻi loa ma nā lathes kiʻekiʻe e hoʻopau i ka hoʻohuli ʻana i nā mea hana metala non-ferrous i ka wikiwiki kiʻekiʻe me ka ʻili o ka ʻili o 0.04-0.01um. Kapa ʻia kēia ʻano huli ʻana he "mirror turning".

Loaʻa i nā mea hana Xinfa CNC nā hiʻohiʻona o ka maikaʻi a me ke kumu kūʻai haʻahaʻa. No nā kikoʻī, e kipa:

2. Ka pololei wili

ʻO ka Milling e pili ana i ka hoʻohana ʻana i nā hāmeʻa hoʻololi i nā ʻaoʻao he nui e ʻoki i nā mea hana, a he ʻano hana maikaʻi loa ia. He kūpono no ka hana ʻana i nā mokulele, nā ʻūhā, a me nā wahi kūikawā e like me nā splines, gears, a me nā mold threaded.

ʻO 6.3-1.6μm ka roughness ili ākea o ka hoʻoili ʻana i ka milling.

ʻO ka roughness ʻili i ka wā o ka wili ʻana he 5-20μm.

ʻO ka roughness ʻili i ka wā semi-finishing milling he 2.5-10μm.

ʻO ka roughness ʻili i ka wā wili maikaʻi ʻo 0.63-5μm.

3.Planing pololei

ʻO ka hoʻolālā kahi ʻano hana ʻoki e hoʻohana ana i kahi planer e hana i nā neʻe pānaʻi a me ka laina laina ma ka mea hana. Hoʻohana nui ʻia no ka hana ʻana o nā ʻāpana.

ʻO ka roughness ili o ka hoʻolālā ʻana ʻo Ra6.3-1.6μm.

ʻO 25-12.5μm ka roughness ili o ka hoʻolālā ʻana.

ʻO ka roughness ili o ka hoʻolālā semi-finishing he 6.2-3.2μm.

ʻO ka roughness ili o ka hoʻolālā maikaʻi he 3.2-1.6μm.

4. wili pololei

ʻO ka wili ʻana e pili ana i kahi ʻano hana e hoʻohana ai i nā abrasives a me nā mea hana abrasive e wehe i nā mea keu mai ka mea hana. He hana hoʻopau a hoʻohana nui ʻia i ka ʻoihana hana mīkini.

Hoʻohana pinepine ʻia ka wili no ka semi-hoʻopau a me ka hoʻopau ʻana, a ʻo ka roughness o ka ʻili he 1.25-0.16μm. ʻO 0.16-0.04μm ka wili ʻana o ka ʻili.

ʻO ka roughness o ka ultra-precision grinding he 0.04-0.01μm.

Hiki i ka roughness ili o ka wili aniani ke hiki i lalo o 0.01μm.

5. ʻOluʻolu a ʻoluʻolu

He kaʻina ʻoki anawaena i loko e hoʻohana ana i kahi mea hana e hoʻonui ai i ka puka a i ʻole ka ʻaoʻao pōʻai ʻē aʻe. ʻO ka laulā hoʻohana maʻamau mai ka semi-roughing a hiki i ka hoʻopau ʻana. ʻO ka mea hana i hoʻohana pinepine ʻia he mea hoʻoheheʻe hoʻokahi ʻaoʻao (i kapa ʻia ʻo ka boring bar).

Hiki ke hōʻea i ka 2.5-0.16μm ka pololei o nā mea kila.

Hiki ke hōʻea i ka 0.63-0.08μm ka pololei o ka hoʻoili ʻana o ka boring precision.
