Nā Pōmaikaʻi o ka ʻoki ʻana i ka Plasma

ʻO ka ʻoki plasma, i kekahi manawa i ʻike ʻia ʻo ka ʻoki arc plasma, he hana hoʻoheheʻe ia. Ma kēia kaʻina hana, hoʻohana ʻia kahi jet o ke kinoea ionized ma nā mahana ma luna o 20,000°C e hoʻoheheʻe i ka mea a kipaku aku iā ia mai ka ʻoki.

I ke kaʻina hana ʻoki plasma, paʻi kahi arc uila ma waena o kahi electrode a me ka workpiece (a i ʻole cathode a me anode). A laila hoʻokomo ʻia ka electrode i loko o kahi nozzle kinoea i hoʻomaʻalili ʻia, e kaupalena ana i ke arc a hana i ka jet plasma haiki, wikiwiki kiʻekiʻe, wela kiʻekiʻe.

Pehea e hana ai ka ʻoki ʻana i ka plasma?

Ke hoʻokumu ʻia ka jet plasma a paʻi i ka ʻāpana hana, hana ʻia ka hui hou ʻana, e hoʻihoʻi ana i ke kinoea i kona kūlana mua a hoʻopuka ia i ka wela nui ma o kēia kaʻina hana. Hoʻoheheʻe kēia wela i ka metala, e kipaku ana iā ia mai ka ʻoki me ke kahe kinoea.

Hiki i ka ʻoki ʻana i ka plasma ke ʻoki i nā ʻano mea hoʻoheheʻe uila like ʻole e like me ke kalapona maʻemaʻe/kila kila, nā mea hoʻoheheʻe alumini a me nā mea hoʻoheheʻe alumini, nā mea hoʻoheheʻe titanium a me nā nickel. Ua hana mua ʻia kēia ʻano hana e ʻoki i nā mea i hiki ʻole ke ʻoki ʻia e ke kaʻina hana oxy-fuel.

Nā Pōmaikaʻi Koʻikoʻi o ka ʻoki ʻana i ka Plasma

ʻOi aku ka maʻalahi o ka ʻoki ʻana i ka plasma no nā ʻoki mānoanoa waena

ʻOki kiʻekiʻe no ka mānoanoa a hiki i 50mm

ʻO ka mānoanoa kiʻekiʻe loa he 150mm

Hiki ke hana ʻia ka ʻoki ʻana i ka plasma ma nā mea conductive āpau, i ka hoʻohālikelike ʻana i ka ʻoki ʻana i ka lapalapa i kūpono wale no nā metala ferrous.

I ka hoʻohālikelike ʻia me ka ʻoki ʻana i ke ahi, ʻoi aku ka liʻiliʻi o ke kerf ʻoki ʻana o ka plasma

ʻO ka ʻoki ʻana i ka plasma ke ala kūpono loa e ʻoki ai i ke kila kila kila a me ka alumini

ʻOi aku ka wikiwiki o ka ʻoki ʻana ma mua o ka oxyfuel

Hiki i nā mīkini ʻoki plasma CNC ke hāʻawi i ka pololei maikaʻi loa a me ka hana hou ʻana.

Hiki ke hana ʻia ka ʻoki ʻana i ka plasma i loko o ka wai e hopena ai i nā wahi liʻiliʻi i hoʻopilikia ʻia e ka wela a me ka hoʻēmi ʻana i nā pae walaʻau.

Hiki i ka ʻoki ʻana i ka plasma ke ʻoki i nā ʻano paʻakikī no ka mea he kiʻekiʻe kona pololei. ʻO ka hopena o ka ʻoki ʻana i ka plasma he liʻiliʻi loa ka lepo no ka mea e hoʻopau ke kaʻina hana ponoʻī i nā mea keu, ʻo ia hoʻi, ʻaʻole nui ka hoʻopau ʻana e pono ai.

ʻAʻole alakaʻi ka ʻoki ʻana i ka plasma i ka warping ʻoiai ʻo ka wikiwiki wikiwiki e hōʻemi nui ai i ka hoʻoili wela.
