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 like i ka mīkini: tungsten carbide cemented i hui pū ʻia me nā uhi a me nā hana 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 mea hana 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, he pilikia paʻakikī loa ia no ka mea ʻo 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 nā mea hoʻohana i ke ʻano o ka 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 waiwai kumu i nā waiwai i makemake ʻia, hoʻohui nā mea hana waiwai i nā mea hoʻohui like ʻole iā ia.ʻO ka mea hoʻohuihui nui he cobalt (Co).ʻO nā pae kiʻekiʻe o ka cobalt e hāʻawi i ka ʻoi aku ka paʻakikī a me nā pae haʻahaʻa o ka cobalt e hoʻonui 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 nā microcracks ma 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 kalapona o titanium nitride, alumini oxide a me titanium nitride.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 lāʻau lapaʻau maʻamau he sandblasting a i ʻole nā ʻano polishing ʻē aʻe e hoʻomaʻemaʻe i ka papa luna a hōʻemi i ka friction, e hōʻemi ana i ka hana wela.ʻO ka ʻokoʻa kumu kūʻai maʻamau he liʻiliʻi loa a ma ka nui o nā hihia e ʻōlelo ʻia e makemake i nā ʻano like ʻole i mālama ʻia.
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 pakuhi e wehewehe i nā pae hana i manaʻo ʻia no nā māka e pili ana i kahi "ʻano hoʻohana" i hōʻike ʻia ma ke ʻano he hui alphanumeric ʻekolu, e like me P05-P20.
Hōʻike ka leka mua i ka pūʻulu mea ISO.Hāʻawi ʻia kēlā me kēia hui mea i kahi leka a me kahi kala e pili ana.
ʻO nā helu ʻelua aʻe e hōʻike ana i ka paʻakikī pili o nā māka mai 05 a i 45 i ka hoʻonui ʻana o 5. Pono nā noi 05 i kahi papa paʻakikī no nā kūlana kūpono a paʻa.45 Nā noi e koi ana i nā huila paʻakikī loa no nā kūlana 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 nā māka i kaha ʻia i ka P10-P20 i loko o ʻelua papa inoa mai nā mea hoʻolako like ʻole.
He ʻokoʻa ka paʻakikī o ka papa i kaha ʻia ma P10-P20 ma ka papa hoʻohuli papa ma mua o ka papa i kaha ʻia ʻo P10-P20 i loko o ka papa wili, ʻoiai ma ka papa helu like.ʻO kēia ʻokoʻa i lalo i ka ʻoiaʻiʻo o nā kūlana maikaʻi e ʻokoʻa mai ka noi i ka noi.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 ka hana hoʻohuli ʻana i ka paʻakikī like ʻole, hiki ke helu ʻia ma ka papa inoa o kahi 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 nā peʻa, ʻaʻohe kūlana kūhelu no nā inoa inoa.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 ISO / ANSI maʻamau, ua hana kekahi mau mea kūʻai aku i kā lākou hoʻoponopono ponoʻī i ka ʻōnaehana, a he mea naʻauao ke ʻike i kēia mau loli.
ʻOi aku ma mua o nā noi ʻē aʻe, he kuleana koʻikoʻi nā alloys i ka hoʻohuli ʻana i nā hana.Ma muli o kēia, e loaʻa i kahi ʻaoʻao huli ka koho nui loa o nā māka ke nānā ʻana i ka papa inoa o nā mea hoʻolako.
ʻO ka laulā ākea o ka hoʻohuli ʻana i nā māka ka hopena o ka nui o nā hana hoʻohuli.Hāʻule nā mea a pau i loko o kēia ʻāpana, mai ka ʻoki mau ʻana (kahi e pili mau ai ka ʻoki ʻoki me ka mea hana a ʻaʻole ʻike i ka haʻalulu, akā e hoʻoulu i ka wela nui) a hiki i ka ʻoki ʻana (e hoʻoulu ai i nā haʻalulu ikaika).
ʻO ka laulā nui o nā māka huli e uhi pū i ka nui o nā anawaena i ka hana ʻana, mai 1/8″ (3 mm) 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 ka ʻokoʻa o nā māka no kēlā me kēia hui waiwai.Ma kēlā me kēia moʻo, ʻokoʻa nā māka mai nā mea paʻakikī kūpono no ka mīkini hoʻopau ʻia a hiki i nā mea kūpono no ka mīkini hoʻomau.
I ka wili ʻana, ʻoi aku ka liʻiliʻi o nā māka i hāʻawi ʻia.Ma muli o ke ʻano o ka hoʻopili ʻana o ka noi, pono nā mea ʻoki i nā māka paʻakikī me ka paʻakikī 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.I ka wā e ʻoki ai i ke kikowaena, hiki i ka wikiwiki i ka zero ma ka hope o ke ʻoki ʻana, a lilo ka hana i ʻoki ʻoki ʻia.
No laila, pono e kūlike nā māka i hoʻohana ʻia no ka hoʻokaʻawale ʻana me ka nui o ka wikiwiki o ka ʻoki ʻana, a pono e ikaika ka substrate e pale i ka ʻoki ʻana ma ka hopena o ka hana.
He ʻokoʻa nā ʻāwī pāpaʻu i nā ʻano ʻē aʻe.Ma muli o nā mea like me ka huli ʻana, hāʻawi pinepine nā mea kūʻai aku me kahi koho nui o nā mea hoʻokomo grooving i kahi ʻano nui 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 drill he zero mau, a 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.
ʻO nā pauka, nā ʻāpana, a me nā huahana nā ʻano like ʻole o nā ʻoihana e koi nei i ka hana hoʻohui.ʻO Carbide a me nā mea hana nā wahi like ʻole o ka kūleʻa.
ʻO ka holomua o nā mea hana i hiki ke hana i kahi wili hope ceramic e hana maikaʻi ana i ka wikiwiki o ka ʻoki haʻahaʻa a hoʻokūkū me nā wili hope carbide i nā ʻano noi.Hoʻomaka paha kāu hale kūʻai e hoʻohana i nā mea hana seramika.
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 i kēia manawa a i ʻole i loko o ka wili like ʻole a i ʻole ka huli ʻana i nā ʻeke e like me ka hoʻokomo carbide, akā ʻo ia kahi e pau ai nā mea like.
