Polycrystalline Diamond （PCD） Mea Hana ʻoki

Hoʻomohala ʻana i nā mea hana ʻoki PCD

Hoʻohana ʻia ʻo Diamond ma ke ʻano he mea hana paʻakikī loa i ka ʻoki ʻana i ka hana ʻana, nona ka mōʻaukala o nā haneli mau makahiki. I ke kaʻina hana o ka ʻoki ʻana i nā mea hana mai ka hopena o ke kenekulia 19 a i ka waena o ke kenekulia 20, ua hōʻike nui ʻia nā mea paahana e ke kila kiʻekiʻe. I ka makahiki 1927, ua hoʻomohala mua ʻo Kelemania i nā mea hana carbide a loaʻa i hoʻohana nui ʻia.

I ka makahiki 1950, ua hana pū ʻo Suedena a me ʻAmelika i nā mea hana ʻoki daimana artificial, no laila ke komo nei i kahi manawa i hōʻike ʻia e nā mea paʻakikī. I ka 1970s, polycrystalline diamond (PCD) i hoʻohui ʻia me ka hoʻohana ʻana i ka ʻenehana synthesis kiʻekiʻe, ka mea i hoʻonui i ka laulā noi o nā mea hana daimana i ka mokulele, aerospace, nā kaʻa, nā uila, nā pōhaku, a me nā māla ʻē aʻe.

Nā hiʻohiʻona hana o nā mea hana PCD

Loaʻa i nā mea hana ʻoki daimana nā hiʻohiʻona o ka paʻakikī kiʻekiʻe, ka ikaika compressive kiʻekiʻe, ka conductivity thermal maikaʻi, a me ke kūpaʻa ʻana, hiki ke hoʻokō i ka pololei machining kiʻekiʻe a me ka maikaʻi i ka ʻoki wikiwiki.

Hoʻohana i nā mea hana PCD

Mai ka hana ʻana o ka daimana polycrystalline mua ma Suedena i ka makahiki 1953, ua loaʻa i ka noiʻi ʻana i ka hana ʻoki ʻana o nā mea hana PCD i nā hopena he nui, a ua hoʻonui wikiwiki ʻia ka laulā noi a me ka hoʻohana ʻana i nā mea hana PCD.

I kēia manawa, ʻo nā mea hana kaulana o nā daimana polycrystalline ma waena o ka honua ka nui o De Beers Company o United Kingdom, GE Company o ʻAmelika Hui Pū ʻIa, Sumitomo Electric Co., Ltd. o Iapana, etc. Ua hōʻike ʻia ma ka hapaha mua o 1995, ʻO ka hana paahana PCD o Iapana wale nō i hiki i 107,000 mau ʻāpana. Ua hoʻonui ʻia ka laulā noi o nā mea hana PCD mai ke kaʻina hoʻohuli mua i ka hana wili a me ka wili. Ua hōʻike ʻia kahi noiʻi ma luna o nā mea hana superhard i alakaʻi ʻia e kahi hui Kepani ʻo ka manaʻo nui o ka poʻe e koho i nā mea hana PCD e pili ana i nā pono o ka pololei o ka ʻili, ka pololei ʻana, a me ke ola mea hana ma hope o ka hana ʻana me nā mea hana PCD. Ua hoʻomohala nui ʻia ka ʻenehana synthesis o nā ʻāpana hui daimana.

ZZBETTER PCD mea hana

Hoʻokomo ʻia nā mea hana ZZBETTER PCD i nā māka like ʻole a me nā hoʻonohonoho dimensional. Loaʻa i ka laulā huahana nā māka me ka nui o ka palaoa awelika mai 5 a 25 microns a me kahi anawaena hiki ke hoʻohana ʻia he 62mm. Loaʻa nā huahana ma ke ʻano he disc piha a ʻokiʻoki i nā ʻōlelo aʻoaʻo ma ka ʻokoʻa a me ka mānoanoa papa PCD.

ʻO nā pōmaikaʻi o ka hoʻohana ʻana i ka ZZBETTER PCD ʻo ia ka hāʻawi ʻana i ka hana hilinaʻi a paʻa i ka uku hoʻokūkū. Hoʻomaikaʻi ia i ka maʻalahi o ka hana ʻana, hiki ke hoʻonui i ka nui o nā meaʻai, a hāʻawi i ka pale ʻana i ka ʻaʻahu no nā mea hana like ʻole. Hōʻike ia i nā māka he nui me kahi mea hoʻohui tungsten carbide i ka papa PCD, e hiki ai i nā mea hana hana ke hoʻokuʻu i nā mīkini uila (EDM) a me / a i ʻole nā ​​​​wili uila (EDG) wikiwiki. ʻO kona ākea ākea o nā māka e hiki ai ke maʻalahi i ke koho ʻana i nā mea kūpono no kēlā me kēia noi mīkini

No ka hana laau

E hoʻonui i ka nui o nā meaʻai a hoʻomaikaʻi i ke ola mea hana i nā noi hana lāʻau e like me ka medium-density fiberboard (MDF), melamine, laminates, a me ka particleboard.

No ka oihana kaumaha

E hoʻonui i ka pale ʻana a hoʻemi i ka manawa hoʻohaʻahaʻa i ka pōhaku mīkini, ka ʻuala, ka papa sima, a me nā mea hana abrasive ʻē aʻe.

Nā noi ʻē aʻe

E hōʻemi i nā kumukūʻai mea hana a hoʻonui i ka paʻa ʻana no kahi ākea o nā mea paʻakikī i ka mīkini, e like me ka carbon composites, acrylics, aniani, a me nā mea ʻē aʻe he nui ʻole a me nā mea nonmetallic.

Nā hiʻohiʻona i hoʻohālikelike ʻia me nā mea hana tungsten carbide:

1, ʻO ka paʻakikī o ka PCD he 80 a 120 mau manawa o ka tungsten carbide.

2. ʻO ka thermal conductivity o PCD he 1.5 a 9 mau manawa o ka tungsten carbide.

3. Hiki i nā mea hana PCD ke ola ma mua o 50 a 100 mau manawa.

Nā hiʻohiʻona i hoʻohālikelike ʻia me nā mea hana daimana maoli:

1, ʻoi aku ka paʻa o ka PCD ma mua o nā daimana maoli ma muli o ke ʻano o ka hoʻonohonoho ʻana o nā ʻāpana daimana a kākoʻo ʻia e kahi substrate carbide.

2, ʻoi aku ka paʻa o ka PCD ma muli o kahi ʻōnaehana hana piha no ka mālama ʻana i ka maikaʻi, ʻo ka daimana maoli he aniani hoʻokahi i ke ʻano a he mau ʻano palupalu a paʻakikī ke hana ʻia i mea hana. ʻAʻole ia e hoʻohana maikaʻi ʻia me nā hua palupalu.

3, ʻoi aku ka liʻiliʻi o ka PCD a loaʻa nā ʻano like ʻole a me nā nui e koho ai no ka mea hana, ʻo ke daimana maoli ka palena o kēia mau kiko.

Hoʻohana nui ʻia nā mea ʻoki ʻoki PCD i ka ʻoihana ma muli o ko lākou maikaʻi hana maikaʻi a me ka hoʻokele waiwai. Hōʻike ia i nā mea maikaʻi ʻaʻole hiki ke hoʻohālikelike ʻia nā mea hana ʻē aʻe no nā mea non-metallic, non-ferrous metala a me kā lākou mau mea hoʻohui, a me nā hana ʻoki ʻē aʻe. ʻO ka hoʻonui ʻana i ka noiʻi ʻana i nā mea hana ʻoki PCD e hāpai i ke kūlana o nā mea hana PCD ma ke kahua o nā mea hana paʻakikī. E lilo ana ka PCD i mea koʻikoʻi, a e hoʻonui ʻia hoʻi kāna palapala noi.
