No ka mea, ʻaʻohe pae honua e wehewehe ana i nā māka carbide a i ʻole nā noi, pono nā mea hoʻohana e hilinaʻi i kā lākou manaʻo ponoʻī a me ka ʻike kumu e kūleʻa ai.#kumu
ʻOiai ʻo ka huaʻōlelo metallurgical "carbide grade" e pili pono ana i ka tungsten carbide (WC) i hoʻopaʻa ʻia me ka cobalt, ʻoi aku ka nui o ka manaʻo o ka huaʻōlelo i ka mīkini: tungsten carbide cemented i hui pū ʻia me nā uhi a me nā lāʻau lapaʻau ʻē aʻe.No ka laʻana, ʻelua mea hoʻokomo huli i hana ʻia mai ka mea carbide hoʻokahi akā me nā ʻāpana ʻokoʻa a i ʻole ma hope o ka mālama ʻana i manaʻo ʻia he mau māka ʻokoʻa.Eia nō naʻe, ʻaʻohe mea maʻamau i ka hoʻokaʻawale ʻana o ka carbide a me ka hui pū ʻana, no laila, hoʻohana nā mea hoʻolako ʻokiʻoki ʻokoʻa i nā inoa like ʻole a me nā ʻano hoʻohālikelike i kā lākou papa papa.Hiki i kēia ke paʻakikī i ka mea hoʻohana hope ke hoʻohālikelike i nā māka, kahi pilikia paʻakikī no ka mea hiki i ke kūpono o kahi māka carbide no kahi noi i hāʻawi ʻia hiki ke hoʻopilikia nui i nā kūlana ʻoki a me ke ola mea hana.
No ka hoʻokele ʻana i kēia maze, pono e hoʻomaopopo mua ka mea hoʻohana i ke ʻano o ka hana carbide a pehea e pili ai kēlā me kēia mea i nā ʻano like ʻole o ka mīkini.
ʻO ke kākoʻo ka mea ʻike ʻole o ka hoʻokomo ʻoki ʻana a i ʻole ka mea paʻa paʻa ma lalo o ka uhi ʻana a ma hope o ka mālama ʻana.ʻO ka maʻamau he 80-95% WC.No ka hāʻawi ʻana i ka substrate i nā waiwai i makemake ʻia, hoʻohui nā mea hana waiwai i nā ʻano alloying like ʻole.ʻO ka mea hoʻohuihui nui ʻo ia ka cobalt (Co) - ʻoi aku ka nui o ka ʻike cobalt i ka ʻoi aku ka paʻakikī, ʻoiai ʻo ka haʻahaʻa haʻahaʻa e hoʻonui ai i ka paʻakikī.Hiki i nā substrates paʻakikī loa ke hiki i 1800 HV a hāʻawi i ke kūpaʻa ʻaʻahu maikaʻi loa, akā palupalu loa lākou a kūpono wale no nā kūlana paʻa loa.ʻO ka substrate ikaika loa he paʻakikī ma kahi o 1300 HV.Hiki ke hoʻohana wale ʻia kēia mau substrates ma nā wikiwiki ʻoki haʻahaʻa, ʻoi aku ka wikiwiki o lākou, akā ʻoi aku ka pale ʻana i nā ʻoki i hoʻopau ʻia a me nā kūlana ʻino.
ʻO ke kaulike kūpono ma waena o ka paʻakikī a me ka paʻakikī ka mea nui loa i ke koho ʻana i kahi alloy no kahi noi.ʻO ke koho ʻana i kahi papa paʻakikī hiki ke hopena i ka micro-breakage o ka ʻoki ʻoki a i ʻole ka pōʻino pōʻino.I ka manawa like, pau koke nā māka paʻakikī a i ʻole e hoʻemi i ka wikiwiki o ka ʻoki ʻana, e hōʻemi ana i ka huahana.Hāʻawi ka Papa 1 i kekahi mau alakaʻi kumu no ke koho ʻana i ka durometer kūpono:
ʻO ka hapa nui o nā mea hoʻokomo carbide hou a me nā mea hana carbide i uhi ʻia me kahi kiʻiʻoniʻoni lahilahi (3 a 20 microns a i ʻole 0.0001 a 0.0007 iniha).ʻO ka uhi maʻamau he mau papa o titanium nitride, alumini oxide a me titanium carbonitride.Hoʻonui kēia uhi i ka paʻakikī a hana i kahi pale wela ma waena o ka ʻoki a me ka substrate.
ʻOiai ua loaʻa ka kaulana ma kahi o hoʻokahi mau makahiki i hala aku nei, ʻo ka hoʻohui ʻana i kahi lapaʻau post-coating ʻē aʻe ua lilo i ka maʻamau ʻoihana.ʻO kēia mau hoʻomaʻamaʻa maʻamau he sandblasting a i ʻole nā ʻenehana polishing ʻē aʻe e hoʻomaʻemaʻe i ka papa luna a hoʻemi i ka friction, a laila e hōʻemi i ka hana wela.ʻOi aku ka liʻiliʻi o ka ʻokoʻa kumu kūʻai a ma ka hapa nui o ka hana ʻana ma hope o ke kaʻina hana no ke koho ʻana i nā ʻano like ʻole.
No ke koho ʻana i ka māka carbide kūpono no kahi noi kūikawā, e nānā i ka catalog a ka mea hoʻolako pūnaewele no nā ʻōlelo kuhikuhi.ʻOiai ʻaʻohe kūlana maʻamau o ka honua, hoʻohana ka hapa nui o nā mea kūʻai aku i nā palapala kiʻi e wehewehe i ka pae hana i manaʻo ʻia o nā māka e pili ana i ka "scope" i hōʻike ʻia ma ke ʻano he hui ʻekolu leka/helu, e like me P05-P20.
Hōʻike ka leka mua i ka pūʻulu waiwai e like me ke kūlana ISO.Hāʻawi ʻia kēlā me kēia hui mea i kahi leka a me kahi kala e pili ana.
Hōʻike nā helu ʻelua i ka pae paʻakikī pili o ka papa, mai ka 05 a hiki i ka 45 ma ka hoʻonui ʻana o 5. Pono nā noi 05 i kahi papa paʻa loa kūpono no nā kūlana kūpono a paʻa.45 He palapala noi e koi ana i kahi papa paʻakikī loa kūpono no nā kūlana paʻakikī a paʻa ʻole.
Eia hou, ʻaʻohe mea maʻamau no kēia mau waiwai, no laila pono lākou e unuhi ʻia ma ke ʻano he mau waiwai pili i ka papa kuhikuhi kikoʻī i ʻike ʻia ai lākou.No ka laʻana, ʻokoʻa ka paʻakikī o kahi papa i kaha ʻia i ka P10-P20 i ʻelua papa inoa mai nā mea hoʻolako like ʻole.
ʻOiai ma ka papa helu hoʻokahi, ʻokoʻa ka paʻakikī o ka papa i kaha ʻia ma P10-P20 ma ka papa huli ʻana ma mua o ka papa i kaha ʻia ʻo P10-P20 ma ka papa wili.Hiki mai kēia ʻokoʻa i nā kūlana maikaʻi like ʻole no nā noi like ʻole.ʻOi aku ka maikaʻi o ka hoʻohuli ʻana me nā māka paʻakikī, akā i ka wā e wili ai, pono nā kūlana maikaʻi i kahi ikaika ma muli o ke ʻano intermittent.
Hāʻawi ka Papa 3 i ka papaʻaina hypothetical o nā mea hao a me kā lākou hoʻohana ʻana i nā hana hoʻohuli paʻakikī i hiki ke helu ʻia i loko o ka papa inoa o ka mea hoʻolako mea hana ʻoki.Ma kēia laʻana, ʻōlelo ʻia ka papa A no nā kūlana huli a pau, akā ʻaʻole no ka ʻoki ʻoki kaumaha, ʻoiai ʻo ka papa D no ka hoʻohuli nui ʻana a me nā kūlana maikaʻi ʻole.Hiki i nā mea hana e like me MachiningDoctor.com's Grades Finder ke ʻimi i nā māka me kēia notation.
E like me ka loaʻa ʻole o ke kūlana kūhelu no ka laulā o kahi papa, ʻaʻohe kūlana kūhelu no ka hoʻolālā papa.Eia nō naʻe, ʻo ka hapa nui o nā mea hoʻokomo carbide nui e hahai i nā alakaʻi maʻamau no kā lākou papa inoa.Aia nā inoa “Classic” ma ke ʻano ʻeono huaʻōlelo BBSSNN, kahi:
Ua pololei ka wehewehe ʻana i luna ma nā hihia he nui.Akā, no ka mea, ʻaʻole kēia he maʻamau ISO/ANSI, hana kekahi mau mea kūʻai aku i kā lākou hoʻoponopono ponoʻī i ka ʻōnaehana, a he mea naʻauao ke ʻike i kēia mau loli.
He kuleana koʻikoʻi nā māka i ka hoʻohuli ʻana i nā noi ma mua o nā noi ʻē aʻe.No laila, i ka wā e ʻimi nei i ka papa inoa o nā mea hoʻolako, e loaʻa i ka ʻaoʻao huli ka koho nui loa o nā māka.
ʻO kēia ākea ākea o ka huli ʻana i nā māka ka hopena o ka nui o nā hana hoʻohuli.Aia kēia ʻāpana mai ka ʻoki mau ʻana (kahi e hoʻopili mau ai ka ʻoki ʻoki me ka mea hana a ʻaʻole i hoʻopilikia ʻia, akā e hoʻoulu ai i ka wela nui) a hiki i ka ʻoki ʻoki ʻia (kahi e loaʻa ai nā hopena ikaika).
Hoʻopili pū ʻia kahi ākea o nā māka huli me nā anawaena like ʻole i ka hana ʻana, mai 1/8″ (3mm) no nā mīkini ʻano swiss a hiki i 100″ no ka hoʻohana ʻana i ka ʻoihana kaumaha.No ka mea e pili ana ka wikiwiki o ka ʻoki ʻana i ke anawaena, koi ʻia nā māka like ʻole i hoʻopaʻa ʻia no nā wikiwiki ʻoki haʻahaʻa a kiʻekiʻe paha.
Hāʻawi pinepine nā mea hoʻolako nui i nā māka kaʻawale no kēlā me kēia hui waiwai.Loaʻa nā māka i kēlā me kēia moʻo mai nā mea paʻakikī no ka ʻoki ʻana i nā mea paʻakikī no ka ʻoki mau ʻana.
I ka wili ʻana, ʻoi aku ka liʻiliʻi o nā māka i hāʻawi ʻia.Ma muli o ke ʻano intermittent o ka noi, pono nā mea hana wili i nā māka paʻakikī me ke kūpaʻa hopena kiʻekiʻe.No ke kumu like, pono e lahilahi ka uhi, inā ʻaʻole ia e pale i ka hopena.
ʻO ka hapa nui o nā mea hoʻolako e wili i nā pūʻulu mea like ʻole me nā kāʻei paʻa a me nā uhi ʻokoʻa.
I ka wā e hoʻokaʻawale ai a i ʻole grooving, ua kaupalena ʻia ke koho ʻana ma muli o nā kumu wikiwiki.ʻO ia hoʻi, e liʻiliʻi ke anawaena ke hoʻokokoke ka ʻoki i ke kikowaena.No laila, hoʻemi mālie ʻia ka wikiwiki ʻoki.Ke ʻoki ʻana i ke kikowaena, hiki i ka wikiwiki ka zero ma ka hope o ke ʻoki ʻana, a lilo ka hana i kahi ʻoki ʻoki.
No laila, pono e kūlike ka maikaʻi o ka hoʻokaʻawale ʻana me kahi ākea o ka wikiwiki o ka ʻoki ʻana, a pono e ikaika ka substrate e pale aku i ka ʻoki ma ka hopena o ka hana.
He ʻokoʻa nā ʻāwī pāpaʻu i nā ʻano ʻē aʻe.Ma muli o ka like me ka huli ʻana, hāʻawi pinepine nā mea hoʻolako me kahi koho ākea o nā mea hoʻokomo grooving i kahi ākea ākea o nā māka no kekahi mau hui a me nā kūlana.
I ka wā e wili ai, ʻo ka wikiwiki o ka ʻoki ʻana i waenakonu o ka puʻu he zero mau, ʻoiai ʻo ka wikiwiki o ka ʻoki ʻana ma ka ʻaoʻao e pili ana i ke anawaena o ka drill a me ka wikiwiki o ka rotation o ka spindle.ʻAʻole kūpono nā māka i hoʻopaʻa ʻia no ka wikiwiki ʻoki kiʻekiʻe a ʻaʻole pono e hoʻohana.Hāʻawi ka hapa nui o nā mea kūʻai aku i nā ʻano like ʻole.
Nui nā hale kūʻai i kuhi hewa i ka noʻonoʻo ʻana he plug-and-play nā mea hana kiʻekiʻe.Hiki i kēia mau mea paahana ke komo i loko o nā mea paʻa paʻa i kēia manawa a komo pū i loko o ka wili pūpū like ʻole a i ʻole nā ʻeke huli e like me ka hoʻokomo carbide, akā ma laila ka pau ʻana o nā mea like.
ʻO nā pauka, nā ʻāpana, a me nā huahana nā ʻano like ʻole o nā ʻoihana e koi nei i ka hana hoʻohui.ʻO ka Carbide a me nā mea hana ʻoki nā wahi like ʻole o ka kūleʻa.
ʻO ka Ceratizit WTX-HFDS series of drills i mālama iā OWSI 3.5 mau minuke i kēlā me kēia ʻāpana i nā hana paʻakikī a hoʻopau loa i nā hana pono ʻole, e hoʻonui ana i ka loaʻa kālā.
