Ka hopena wela ma ka PDC Cutter

Ua ʻike ʻia he ʻoi aku ka maikaʻi o nā bits PDC ma mua o nā ʻāpana cone roller, akā ʻike ʻia kēia i ka wā e wili ana i nā pōhaku palupalu. Hiki paha kēia ma muli o ka 50% o ka ikehu no ka wili ʻana hiki ke hoʻopau ʻia e kahi ʻoki ʻoki. Ma waho aʻe o ka ʻaʻahu i hoʻokumu ʻia e ka pilina ma waena o ka pōhaku a me ka ʻokiʻoki, hiki i nā hopena wela ke hoʻolalelale i ka wikiwiki o ka ʻoki ʻana.

Inā mālama ʻole ʻia nā hopena wela, hiki ke hopena i ka ʻaʻahu ʻuʻuku he hana wale nō ia o ka haʻawe i hoʻopili ʻia i kahi liʻiliʻi a me ka mamao i hele i ka wā e pili ana me ka pōhaku. E like me kā mākou ʻike, ʻaʻole kēia ka hihia. Loaʻa ka hopena wela i ka nui o ke komo ʻana o nā bits.

Ua ʻōlelo ʻia ʻo ka ʻaʻahu abrasive o ka metala e pili ana i ka lākiō paʻakikī o nā mea abrasive a me ka metala. No nā abrasive palupalu me ka ratio ma lalo o 1.2, haʻahaʻa ka lakene ʻaʻahu. ʻOiai ʻoi aku ka nui o ka paʻakikī pili i ka 1.2, piʻi nui ka nui o ka lole.

I ka nānā 'ana i ka quartz, aia ma kahi o 20- 40% o ka nui o nā pōhaku, aia ka pa'akikī ma waena o 9.8-11.3GPa a me ka tungsten carbide he 10-15GPa. Loaʻa kēia mau pae i kahi ratio mai 0.65 a 1.13, e hoʻokaʻawale ana i kēia pilina ma ke ʻano he abrasive palupalu. Ke hoʻohana ʻia ka tungsten carbide no ka ʻoki ʻana i nā pōhaku ma lalo a i ʻole 350 oC, ʻike lākou i ka nui o ka ʻaʻahu e like me ka abrasive palupalu e like me ka mea i manaʻo ʻia.

Ke ʻoi aku ka mahana ma mua o 350 oC, hoʻonui ʻia ka ʻaʻahu a hui maikaʻi ʻia me ka mea abrasive paʻakikī. Mai kēia, ua hoʻoholo ʻia e hoʻonui ʻia ka lole e ka hopena wela. No ka hōʻemi ʻana i ka lole PDC, ʻoi aku ka maikaʻi o ka mālama ʻana i ka mahana o nā mea ʻoki.

I ka hoʻomaka ʻana o ke aʻo ʻana i nā hopena wela ma ka lole PDC, ʻo 750oC ka wela o ka hana palekana. Ua hoʻokumu ʻia kēia mahana, no ka mea ma lalo o kēia microchipping wela ka ʻaʻahu i ʻike ʻia ma ka ʻoki.

Ma luna o 750 ℃ ​​ua wehe ʻia nā hua daimana piha mai ka papa daimana a i ka hiki ʻana i nā mahana ma luna o 950 ℃ ua ʻike ka tungsten carbide stud i ka deformation plastic. Pono ka hoʻomaopopo ʻana i nā mea ʻoki a me ka PDC bit geometry e hāʻawi i ka ʻike kūpono i ka wā e koho ai.

Hāʻawi ʻo Zzbetter i kahi ʻoki PDC kiʻekiʻe me ka paʻa wela maikaʻi. Ke hana ikaika nei kā mākou hui e hana i nā huahana maikaʻi. Manaʻo mākou i ka lawelawe ʻana i kāu ʻoihana.

Inā makemake ʻoe i nā mea ʻoki PDC a makemake ʻoe i nā ʻike hou aʻe a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole ka leka uila ma ka hema, a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao.
