Nā pāpaʻihoʻohana ʻia e like me ka hoʻonohonoho piha ʻana o nā mea hoʻokaʻawale ea i nā ʻōnaehana kemika, a ʻo ka hapa nui o kā lākou mau mea hoʻopaʻa i hana ʻia me ke kila kila.I ke kaʻina hana wili, ma muli o ke koho kūpono ʻole o nā mea wili a me nā ʻano wili hewa ʻole, ʻaʻole wale ka hoʻemi ʻana o ka hana ʻana o ka valve, akā ua hoʻopilikia nui ʻia ka maikaʻi o ka huahana.Wahi a nā hiʻohiʻona o nā mea kila kila, ua koho mākou i ka ikaika o ka hana ikaika a me ke kūpaʻa ʻana, a ke hoʻopilikia mau ʻia ka maikaʻi o ka huahana ma hope o ka haki ʻana o nā ʻāpana abrasive i ka hana.I nā makahiki i hala iho nei, ua aʻo mākou i nā mea abrasive nona nā hana o nā mea abrasive hiki ke mālama i ka ʻoi, e like me ka corundum keʻokeʻo a me ka chromium oxide, ke koho ʻana i nā mea hana abrasive a me ke ʻano abrasive, a me nā mea ʻē aʻe. a me W5, a pela aku. Eha kupono.Ma o ka hoʻokolohua, ua hoʻokiʻekiʻe ʻia a hoʻohana ʻia i ka hana maoli, ʻaʻole ia e hoʻomaikaʻi wale i ka maikaʻi o ka ʻili o ka sila, akā hoʻomaikaʻi pū i ka hana hana a loaʻa nā hopena maikaʻi loa.
No ka pahu e wili ai i ka mea hana, ʻo ka mea mua, ua hoʻokomo ʻia ka mea wili me ke one, a laila e hoʻokō ʻia ka wili ʻana ma ke ʻano o kahi abrasive i haku ʻia me ka hui ʻana o nā ʻōpala abrasive a me kahi wai wili.ʻO ka ikaika wili e pili ana i ka ikaika e hana ana ma luna o ka ʻāpana wili ili.ʻO ia ka ikaika i hoʻohana ʻia i ka mea hana wili a hana ma ka ʻili e hana ʻia ma o nā ʻāpana abrasive.Inā liʻiliʻi ke kaomi, liʻiliʻi ka hopena wili, a piʻi ke kaomi.Hoʻonui ʻia ka hopena wili, a ʻoi aku ka maikaʻi o ka wili.Eia naʻe, i ka piʻi ʻana o ke kaomi i kekahi waiwai, hiki mai ka saturation, a hiki i ka pono wili i ka waiwai nui.Ma hope o kēlā, inā hoʻomau ka hoʻonui ʻia ʻana o ke kaomi ma kēlā me kēia ʻāpana, e emi ana ka pono.
ʻO kēia ke kumu no ka loaʻa ʻana o nā ʻāpana abrasive valve i kahi palena o ke kūpaʻa kaomi.Ke hoʻonui ʻia kēia waiwai palena, e ʻoki ʻia lākou, e ʻoi aku ka maikaʻi o nā ʻāpana abrasive a hoʻohaʻahaʻa i ka hiki ke wili iā ia iho.No laila, pono e hoʻoholo ʻia ke kaomi ʻāpana e like me ka ikaika a me nā hiʻohiʻona o ka abrasive.Ma hope o ka hoʻāʻo ʻana, pono e koho maʻamau nā ʻāpana: ① I ka wili ʻana, no ka corundum abrasive keʻokeʻo, koho 0.2 a 0.5 MPa.③ I ka wili maikai ana, koho 0.03～0.12MPa no ka jade abrasive keokeo.
ʻO ka māmā wili e pili ana i ka wikiwiki o ka neʻe ʻana o ka mea hana wili ma ka ʻili o ka mea hana.ʻO ka wikiwiki o ka wili he mea koʻikoʻi kaʻina hana no ka mālama ʻana i ka nui o ka wehe ʻana i ke koena, ka wikiwiki o ka wehe ʻana a me ka maikaʻi o ka ʻili i hana ʻia.ʻO ke kiʻi 2 kahi ʻāpana pili maʻamau ma waena o ka wehe ʻana i ka nui o ka mea hana, ka ʻili o ka mīkini a me ka wikiwiki o ka wili.
ʻO ka hana o ka mea hana wili a me kāna mea hana wili mea e hoʻoponopono i ka abrasive a loaʻa i kahi neʻe wili, a hoʻololi i kona ʻano geometric ponoʻī i ka mea hana ma kekahi ala.No laila, pono i ka mea o ka wili ke hoʻokomo pono i nā hua abrasive a me ka mālama lōʻihi o kona pololei geometric ponoʻī.ʻO ka hao hina hina HT200 kahi mea kūpono no ka hana ʻana i nā wili.Aia i loko o kona hale ka cementite paʻakikī a paʻa i ka lole, ferrite me ka paʻakikī a me ka plasticity, a loaʻa pū kekahi i ka graphite, he hopena lubricating a maʻalahi ke hana a hana..
Ke ʻoi aku ka nui o ka manawa wili e loaʻa ai ka maikaʻi o ka ʻili i ʻōlelo ʻia ma mua o ka manawa e pono ai e wehe i ka palena.Pono e hoemi pono ia ka mama wili.Ma hope o ka hoʻāʻo ʻana, ʻoi aku ka kūpono o kēia mau helu wikiwiki: ①I ka wā o ka wili ʻana, ʻo 20-50m/min ka wikiwiki o ka wili ʻana i nā mea hana a i ʻole nā mea hana.②I ka wili maikaʻi ʻana o ka valve, ʻo 6 ~ 12m / min ka wikiwiki o ka mea wili a i ʻole ka mea hana.ʻO ke koho ʻana i ka waiwai o ka ʻili o ka ʻili ʻo ia kekahi o nā hōʻailona nui o ka maikaʻi o ka ʻili.He mana nui kona i ka hana o ka ili.He hopena pololei ia i ka abrasion o ka ʻili, ka paʻakikī pili a me ka hana hoʻopaʻa ʻana, a ma ka manawa like e pili ana i ka hana a me ke ola o ka huahana.I ka hoʻohana ʻana i nā ʻano wili like ʻole a me ka nui o nā ʻāpana, ʻokoʻa hoʻi ka ʻawaʻawa o ka ʻili.
