ʻO ke kaʻina hana o ka ʻoki ʻana i ka metala laser

Me ka ʻenehana ʻoki laser, ua hoʻohana nui ʻia ka ʻoki laser a ke piʻi nei hoʻi nā mea kūpono. Eia nō naʻe, he ʻokoʻa nā waiwai o nā mea like ʻole, no laila he ʻokoʻa hoʻi nā mea e pono ai ka nānā ʻana i ka ʻoki laser. ʻO ka laser gula i ka ʻoihana ʻoki laser no nā makahiki he nui, ma hope o kahi manawa lōʻihi o ka hana mau i hōʻuluʻulu ʻia no nā mea like ʻole nā ​​​​mea e noʻonoʻo ai i ka ʻoki laser.

Ke kila kūkulu
Hiki ke loaʻa nā hopena maikaʻi aʻe i ka mea me ka ʻoki ʻana me ka oxygen. Ke hoʻohana ʻia ka oxygen ma ke ʻano he kinoea hana, e hoʻomake iki ʻia ka ʻoi ʻoki. ʻO ka mānoanoa o ka pepa he 4mm, hiki ke hoʻohana ʻia ka naikokene ma ke ʻano he ʻoki kaomi kinoea hana. I kēia hihia, ʻaʻole i hoʻomake ʻia ka ʻoi ʻoki. ʻO ka mānoanoa o 10mm a ʻoi aku paha o ka pā, hiki i ka laser a me ka hoʻohana ʻana i nā papa kūikawā i ka ʻili o ka workpiece i ka wā o ka mīkini ʻaila ʻia ke loaʻa kahi hopena maikaʻi aʻe.

Kila kohu ʻole
Pono ka ʻoki ʻana i ke kila kila kila i ka hoʻohana ʻana i ka oxygen. I ke ʻano o ka lihi o ka oxidation, ʻaʻole pono ka hoʻohana ʻana i ka nitrogen e loaʻa ai kahi lihi non-oxidizing a ʻaʻohe burr, ʻaʻole pono e hana hou ʻia. ʻO ka uhi ʻana i ka papa perforated film e loaʻa ai nā hopena maikaʻi aʻe, me ka ʻole o ka hōʻemi ʻana i ka maikaʻi o ka hana ʻana.

Alumini
ʻOiai ke kiʻekiʻe o ka reflectivity a me ka thermal conductivity, hiki ke ʻoki ʻia ka alumini ma lalo o 6mm ka mānoanoa. Aia ia i ke ʻano o ka alloy a me nā hiki laser. I ka wā e ʻoki ai i ka oxygen, ʻo ka ʻili ʻoki he ʻāwili a paʻakikī. Me ka naikokene, he laumania ka ʻili ʻoki. He paʻakikī loa ka ʻoki ʻana i ka alumini maʻemaʻe ma muli o kona maʻemaʻe kiʻekiʻe. Ke kau wale ʻia ma ka ʻōnaehana o ka "reflection-absorption", hiki i ka mīkini ke ʻoki i ka alumini. A i ʻole e luku ia i nā ʻāpana optical reflective.

ʻO ka titanium
ʻO ka pepa Titanium me ke kinoea argon a me ka naikokene ma ke ʻano he kinoea hana e ʻoki ai. Hiki i nā palena ʻē aʻe ke kuhikuhi i ke kila nickel-chromium.

Keleawe a me ke keleawe
Loaʻa i nā mea ʻelua kahi reflectivity kiʻekiʻe a me kahi conductivity thermal maikaʻi loa. Hiki ke hoʻohana ʻia ka mānoanoa o ka nitrogen ma lalo o 1mm no ka ʻoki ʻana i ke keleawe, hiki ke ʻoki ʻia ka mānoanoa keleawe ma lalo o 2mm, pono ke kinoea hana me ka oxygen. Aia wale nō i hoʻokomo ʻia ma ka ʻōnaehana, ʻo "reflection-absorption" ʻo ia hoʻi ke hiki iā lākou ke ʻoki i ke keleawe a me ke keleawe. A i ʻole e luku ia i nā ʻāpana optical reflective.

Mea hana
ʻO ka ʻoki ʻana i nā mea synthetic e hoʻomanaʻo i ka wā e ʻoki ai i nā hoʻokuʻu ʻana o nā mea weliweli a me nā mea hiki ke weliweli. Hiki ke hana ʻia nā mea synthetic: thermoplastics, thermosetting materials, a me ka synthetic rubber.

Nā mea olaola
I loko o nā meaola āpau, aia ka pilikia o ke ahi (me ka naikokene ma ke ʻano he kinoea hana, hiki ke hoʻohana ʻia ka ea i hoʻopaʻa ʻia ma ke ʻano he kinoea hana). Hiki ke ʻoki ʻia ka lāʻau, ka ʻili, ka pepa a me ka pepa me ka laser, hiki i ka ʻoki ke hoʻowela (ʻeleʻele).

Ma o nā mea like ʻole, nā pono like ʻole, me ka hoʻohana ʻana i ke kinoea kōkua kūpono a me ka ʻenehana hana, e loaʻa nā hopena maikaʻi loa.
