Papa hui ʻekolu daimana MT1613 (ʻano Benz)
ʻO ka pepa hui daimana polycrystalline niho triangular, ʻo ka mea he substrate carbide cemented a me ka papa hui daimana polycrystalline, ʻo ka ʻili o luna o ka papa hui daimana polycrystalline he ʻekolu convex me ke kikowaena kiʻekiʻe a me ka periphery haʻahaʻa. Aia kahi ʻili concave wehe ʻāpana ma waena o nā iwi convex ʻelua, a ʻo nā iwi convex ʻekolu he mau iwi convex ʻano triangular i luna ma ka ʻāpana kea; i hiki i ka hoʻolālā hoʻonohonoho o ka papa hui niho wili ke hoʻomaikaʻi nui i ka paʻakikī o ka hopena me ka ʻole o ka hōʻemi ʻana i ke kūpaʻa hopena. E hōʻemi i ka ʻāpana ʻoki o ka pepa hui a hoʻomaikaʻi i ka pono o ka wili ʻana o nā niho wili.
I kēia manawa, hiki i ka ʻoihana ke hana i nā pepa composite non-planar me nā ʻano like ʻole a me nā kikoʻī e like me ke ʻano wedge, ke ʻano triangular cone (pyramid type), ke ʻano truncated cone, ke ʻano triangular Mercedes-Benz, a me ke ʻano flat arc. -
ʻO ka pepa hui daimana polycrystalline S1013
Ua māhele ʻia ʻo PDC i nā moʻo nui nui e like me 19mm, 16mm, a me 13mm e like me nā diameters like ʻole, a me nā moʻo nui kōkua e like me 10mm, 8mm, a me 6mm. Ma keʻano laulā, pono nā PDC anawaena nui i ke kūpaʻa hopena maikaʻi a hoʻohana ʻia i nā ʻano palupalu e hoʻokō i ka ROP kiʻekiʻe; pono nā PDC anawaena liʻiliʻi i ke kūpaʻa ʻaʻahu ikaika a hoʻohana ʻia i nā ʻano paʻakikī e hōʻoia i ke ola lawelawe.
ʻO ka PDC i hana ʻia e kā mākou hui e hoʻohana nui ʻia e like me ka ʻoki ʻana i nā niho no nā ʻāpana ʻeli aila, a hoʻohana ʻia i ka ʻimi ʻaila a me ke kinoea a me ka ʻeli ʻana a me nā mahina ʻē aʻe.
