ʻO nā ʻano o ka drill bit hiki ke hoʻohana ʻia noʻO nā mīkini wili a me nā mīkini wili CNCe hoʻokomo i nā wiliwili wili, nā U, nā hana hoʻomāinoino, a me nā haʻawina kumu.
Hoʻohana nui ʻia nā wili wili i nā paʻi wili poʻo hoʻokahi e wili i nā paneli hoʻokahi maʻalahi.I kēia manawa ʻaʻole ʻike ʻia lākou ma nā mea hana papa kaapuni nui, a hiki i ko lākou hohonu wili ke hiki i 10 mau manawa ke anawaena o ka drill.
I ka wā ʻaʻole kiʻekiʻe ka hoʻopaʻa ʻana o ka substrate, hiki i ka hoʻohana ʻana i nā lima drill ke pale i ka hoʻokaʻawale ʻana.ʻO kaMīkini wili CNCke hoʻohana nei i kahi drill shank carbide i hoʻopaʻa ʻia, i hōʻike ʻia e ka hiki ke hoʻololi i ka drill.ʻO ka pololei kūlana kiʻekiʻe, ʻaʻole pono e hoʻohana i nā lima drill.ʻO ke kihi helix nui, ka wikiwiki o ka wehe ʻana i ka chip, kūpono no ka ʻoki kiʻekiʻe.I loko o ka lōʻihi piha o ka ʻohe chip, ʻo ke anawaena o ka drill he cone inverted, a ʻo ka friction me ka pā puka i ka wā e wili ai he liʻiliʻi, a he kiʻekiʻe ka maikaʻi o ka wili.ʻO 3.00mm a me 3.175mm nā anawaena shank drill maʻamau.
Hoʻohana maʻamau ka pahu drill no ka wili pepa paipu i ka carbide cemented, no ka mea, ʻo ka lole aniani epoxy i uhi ʻia i ka pā keleawe keleawe e hoʻohana wikiwiki i ka mea hana.ʻO ka mea i kapa ʻia ʻo carbide cemented i hana ʻia me ka pauka tungsten carbide e like me ka matrix a me ka pauka cobalt e like me ka mea hoʻopaʻa ma o ke kaomi a me ka sintering.Loaʻa iā ia ka 94% tungsten carbide a me 6% cobalt.Ma muli o kona paʻakikī kiʻekiʻe, ʻaʻahu kūʻokoʻa, loaʻa kahi ikaika, a kūpono no ka ʻoki kiʻekiʻe.
ʻAʻohe paʻakikī a palupalu loa.I mea e hoʻomaikaʻi ai i ka hana o ka carbide cemented, hoʻohana kekahi i kahi papa o 5-7 microns o ka titanium carbide hou aʻe (TIC) a i ʻole titanium nitride (TIN) ma ka substrate carbide e ka hoʻoheheʻe ʻana i ka mahu e hana ai i ʻoi aku ka paʻakikī.Hoʻohana kekahi i ka ʻenehana implantation ion e hoʻokomo i ka titanium, nitrogen, a me ke kalapona i loko o ka matrix i kahi hohonu, ʻaʻole ia e hoʻomaikaʻi wale i ka paʻakikī a me ka ikaika, akā hiki i kēia mau mea i hoʻokomo ʻia ke neʻe i loko i ka wā e hoʻomaka hou ai ka drill bit.Hoʻohana kekahi i nā ʻano hana kino e hana i kahi papa kiʻi daimana ma luna o kadrill bit, ka mea e hoʻomaikaʻi nui ai i ka paʻakikī a me ka pale ʻana o ka drill bit.ʻO ka paʻakikī a me ka ikaika o ka carbide cemented ʻaʻole pili wale i ka ratio o ka tungsten carbide a me ka cobalt, akā i nā ʻāpana o ka pauka.
No nā ʻāpana liʻiliʻi loa o nā bits drill carbide cemented, ʻo ka awelika o ka nui o ka tungsten carbide phase grains ma lalo o 1 micron.ʻAʻole ʻo kēia ʻano drill ka paʻakikī kiʻekiʻe wale nō akā ua hoʻomaikaʻi ʻia ka ikaika compressive a me ka flexural.I mea e mālama ai i nā kumukūʻai, ua hoʻohana ʻia nā ʻāpana drill he nui i kēia manawa i ka hana welded shank structure.Hana ʻia ka pahu drill kumu me ka paʻa paʻa holoʻokoʻa.I kēia manawa ua hana ʻia ka pahu drill hope me ke kila kila, kahi e hoʻemi nui ai ke kumukūʻai.Eia nō naʻe, ma muli o ka hoʻohana ʻana i nā mea like ʻole, ʻaʻole maikaʻi ka concentricity ikaika e like me ka paʻakikī holoʻokoʻa.Alloy drill bit, oi aku no na anawaena liilii.
