Pono ka poʻe kūʻai aku i nā mīkini wili hou e hoʻomaopopo i ka ʻokoʻa a me waho o ke kaʻina hana abrasive, ke ʻano o ka hana abrasive, a me nā ʻano like ʻole o ka lole huila wili.
Ua hoʻololi ʻia kēia pou blog mai kahi ʻatikala i paʻi ʻia e Barry Rogers i ka puke ʻo Nowemapa 2018 o ka Mīkini / Shop supplement of Modern Machine Shop magazine.
Ma ka ʻatikala hope loa e pili ana i ke kumuhana o nā grinders, ua kūkākūkā mākou i ka hoʻopiʻi kumu o nā grinders a me ke ʻano o ke kūkulu ʻia ʻana.I kēia manawa, ke nānā pono nei mākou i ke ʻano o ka hana abrasive a me ke ʻano o nā mea kūʻai aku i nā mīkini hou ma ka mākeke.
ʻO ka wili ʻana he ʻenehana hana abrasive e hoʻohana ana i ka huila wili ma ke ʻano he mea ʻoki.ʻO ka huila wili he mau ʻāpana paʻakikī a ʻoi.Ke kaʻa ka huila, hana kēlā me kēia ʻāpana me he mea hana ʻoki kiko hoʻokahi.
Loaʻa nā huila wili i nā ʻano nui, nā anawaena, nā mānoanoa, ka nui o ka palaoa abrasive a me nā mea paʻa.Ana ʻia nā abrasive ma nā ʻāpana o ka nui a i ʻole ka nui o nā ʻāpana, me ka nui o nā ʻāpana mai ka 8-24 (coarse), 30-60 (medium), 70-180 (fine) a me 220-1,200 (maikaʻi loa).Hoʻohana ʻia nā māka coarser kahi e hoʻoneʻe ʻia ai ka nui o nā mea.ʻO ka mea maʻamau, hoʻohana ʻia kahi papa ʻoi aku ka maikaʻi ma hope o ka papa coarser e hana i kahi hoʻopau ʻili maʻalahi.
Hana ʻia ka huila wili i nā ʻano abrasives, me ka silicon carbide (hoʻohana mau ʻia no nā metala non-ferrous);alumina (hoʻohana ʻia no nā huila hao ikaika a me ka lāʻau; nā daimana (hoʻohana ʻia no ka wili seramika a i ʻole ka polishing hope); a me cubic boron nitride (hoʻohana mau ʻia no ke kila kila).
Hiki ke hoʻokaʻawale hou ʻia nā abrasive ma ke ʻano he mea hoʻopaʻa, uhi ʻia a i hoʻopaʻa ʻia paha.Hoʻopili ʻia ka mea hoʻopaʻa paʻa me nā ʻōpala abrasive a me kahi mea hoʻopili, a laila kaomi ʻia i kahi ʻano huila.Hoʻokuʻu ʻia lākou i nā wela kiʻekiʻe e hana i kahi matrix like me ke aniani, i ʻike mau ʻia ʻo vitrified abrasives.Hana ʻia nā abrasive i uhi ʻia me nā kīʻaha abrasive i hoʻopaʻa ʻia i kahi substrate maʻalahi (e like me ka pepa a i ʻole ka fiber) me ka resin a/a i ʻole ke kāpili.Hoʻohana pinepine ʻia kēia ʻano no nā kāʻei, nā lau, a me nā petals.Hoʻopaʻa ʻia nā mea abrasive i hoʻopaʻa ʻia me ka metala, ʻoi aku ka nui o nā daimana, i loko o ka matrix metala ma ke ʻano o nā huila wili pololei.Hoʻolālā ʻia ka matrix metala e ʻaʻahu e hōʻike i ka media wili.
Hoʻoponopono ka mea hoʻopaʻa a i ʻole ke kikowaena i ka abrasive i ka huila wili a hāʻawi i ka ikaika nui.Hoʻokuʻu ʻia nā puka a i ʻole nā pores i loko o nā huila e hoʻomaikaʻi i ka hāʻawi ʻana i ka mea hoʻomaha a hoʻokuʻu i nā ʻāpana.Ma muli o ka noi o ka huila wili a me ke ʻano o ka abrasive, hiki ke hoʻohui ʻia nā mea hoʻopihapiha ʻē aʻe.Hoʻokaʻawale ʻia nā mea paʻa ma ke ʻano he organik, vitrified a metala paha.Hāʻawi kēlā me kēia ʻano i nā pōmaikaʻi pili pono.
Hiki i nā mea hoʻopili kino a i ʻole resin ke kū i nā kūlana wili paʻakikī, e like me ka haʻalulu a me nā ikaika lateral kiʻekiʻe.He kūpono loa nā mea hoʻopaʻa kino no ka hoʻonui ʻana i ka nui o ka ʻoki ʻana i nā noi mīkini paʻakikī, e like me ke kapa kila a i ʻole nā hana ʻoki abrasive.ʻO kēia mau hui pū kekahi i kūpono i ka wili pololei ʻana o nā mea superhard (e like me ke daimana a i ʻole nā ceramics).
Ma ka wili pololei ʻana o nā mea metala ferrous (e like me ke kila paʻakikī a i ʻole nā mea hoʻoheheʻe nickel), hiki i ka palapala ceramic ke hāʻawi i ka lole maikaʻi a me ka hana ʻoki manuahi.Hoʻonohonoho pono ʻia ka paʻa ceramic e hāʻawi i ka hoʻopili ikaika ʻana i nā ʻāpana cubic boron nitride (cBN) ma o ka hopena kemika, e hopena i kahi ratio maikaʻi loa o ka ʻoki ʻana i ka leo i ka lole huila.
Loaʻa i nā kī metala ke kūpaʻa maikaʻi a me ka paʻa ʻana o ke ʻano.Hiki iā lākou ke hele mai nā huahana electroplated one-layer i nā huila multilayer hiki ke hana ikaika a paʻa.Paʻakikī loa paha nā huila i hoʻopaʻa ʻia metala ke ʻaʻahu maikaʻi.Eia nō naʻe, hiki ke ʻaʻahu ʻia kahi ʻano huila wili hou me kahi kaula hao palupalu i ke ʻano like me ka huila wili seramika a loaʻa iā ia ke ʻano o ka ʻoki manuahi.
I ka wā o ka wili ʻana, e mae ka huila wili, e lilo i polu, e nalowale kona ʻano contour a i ʻole "kaumaha" ma muli o nā ʻāpana a i ʻole nā ʻōpala e pili ana i ka abrasive.A laila, hoʻomaka ka huila wili e hamo i ka mea hana ma mua o ka ʻoki ʻana.Hoʻopuka kēia kūlana i ka wela a hoʻemi i ka pono o nā huila.Ke piʻi aʻe ka ukana huila, hiki ke kamaʻilio, e pili ana i ka pau ʻana o ka ʻili o ka mea hana.E hoʻonui ka manawa pōʻai.I kēia manawa, pono e "ʻaʻahu" ka huila wili e hoʻokala i ka huila wili, a laila e wehe i nā mea i waiho ʻia ma luna o ka ʻili o ka huila wili a hoʻihoʻi i ka huila wili i kona ʻano kumu, ʻoiai e lawe mai ana i nā ʻāpana abrasive hou i luna.
Hoʻohana ʻia nā ʻano mea lole huila wili no ka wili.ʻO ka mea maʻamau ka mea hoʻokahi-point, static, onboard diamond dresser, aia i loko o kahi poloka, maʻamau ma ke poʻo a i ʻole ka huelo o ka mīkini.Ke hele nei ka ili o ka huila wili ma keia wahi daimana, a weheia kekahi wahi huila wili e oi ai.Hiki ke hoʻohana ʻia ʻelua a ʻekolu mau poloka daimana e hoʻololi i ka ʻili, nā ʻaoʻao, a me ke ʻano o ka huila.
ʻO ka rotary trimming kahi ala kaulana i kēia manawa.Hoʻopili ʻia ka mea lole rotary me nā haneli daimana.Hoʻohana maʻamau ia no nā noi wili hānai creep.Ua ʻike nā mea hana he nui no nā kaʻina hana e koi ana i ka hana ʻāpana kiʻekiʻe a/a i ʻole ka ʻae ʻana i nā ʻāpana paʻa, ʻoi aku ka maikaʻi o ka ʻoki ʻana i ka rotary ma mua o ka ʻokiʻoki ʻana a i ʻole ka hui pū.Me ka hoʻokomo ʻana i nā huila superabrasive ceramic, ua lilo ka lole rotary i mea pono.
ʻO ka lole lole Oscillating kekahi ʻano lole lole i hoʻohana ʻia no nā huila wili nui e koi ana i nā paʻi lole hohonu a lōʻihi.
Hoʻohana nui ʻia ka lole lole waho no ka wili ʻana i nā huila mai ka mīkini, ʻoiai e hoʻohana ana i ka mea hoʻohālikelike optical e hōʻoia i ke ʻano o ke ʻano.Hoʻohana kekahi poʻe wili i nā mīkini hoʻokuʻu uwila ʻoki ʻia e kāhiko i nā huila hoʻopaʻa metala i hoʻokomo ʻia ma luna o ka mīkini.
E aʻo hou e pili ana i ke kūʻai ʻana i nā mea hana mīkini hou ma ke kipa ʻana i ka "Machine Tool Buying Guide" ma ka Techspex Knowledge Center.
ʻO ka hoʻomaikaʻi ʻana i nā pōʻai wili camshaft lobe ma ke kuʻuna ma muli o ka ʻepekema, a ʻoi aʻe ma muli o nā kuhi naʻauao a me ka wili hoʻāʻo nui.I kēia manawa, hiki i ka lolouila thermal modeling software hiki ke wānana i ka wahi e hiki mai ana ka ʻā ʻana o ka lobe e hoʻoholo ai i ka wikiwiki o ka hana ʻana ʻaʻole e hoʻopōʻino ka wela i ka lobe, a hoʻemi nui i ka helu o nā wili hoʻāʻo pono.
ʻElua mau ʻenehana hoʻohana-nā huila super abrasive a me ka mana servo kiʻekiʻe-hoʻohui e hāʻawi i kahi kaʻina wili contour e like me nā hana hoʻohuli waho.No ka nui o nā noi wili OD mid-volume, he ala kēia e hoʻohui ai i nā hana hana he nui i hoʻokahi hoʻonohonoho.
No ka mea hiki i ka wili ʻana i nā mea kolo ke loaʻa ka nui o ka lawe ʻana i nā mea waiwai i nā mea paʻakikī, ʻaʻole paha ʻo ka wili wale ka hana hope loa o ke kaʻina hana.
