Honing i ka hana ʻana i nā lāʻau pololei

1. No ke aha e pono ai ka mīkini hoʻonani

Nā lāʻau pololeihe mau mea koʻikoʻi i hoʻohana ʻia i nā mīkini, nā ʻōnaehana automotive, hydraulics, robotics, a me nā hui aerospace.
Hoʻohana pinepine lākou e like meʻāpana maleme na bushings, bearings, or seals, kahi o kaka pau ʻana o ka ʻili, ka poepoe, a me ka pololeipili pono i ka hana ʻōnaehana.

ʻOiai ma hopeka huli ʻana, ka wili ʻana, a i ʻole ka huli paʻakikī, e mau ana paha ka ili o ke kumu:

Nā piko a me nā awāwa(kiʻekiʻe loa ka ʻeleʻele o ka ʻili no ka hoʻopaʻa ʻana a i ʻole ka hoʻopili ʻana).

Kuhi hewae like me ka taper, barrel, or ovality.

ʻO ke koʻikoʻi koenamai ka wili ʻana a i ʻole ka mālama wela.

ʻO nā ʻano lubrication like ʻolema ka ili.

Hiki i kēia mau hemahema ke alakaʻi i:

ʻO ka ʻaʻahu nui ʻana o nā bearings a i ʻole nā ​​sila,

Leakage ma nā ʻōnaehana hydraulic,

ʻO ka walaʻau a i ʻole ka haʻalulu i ka wā o ka hoʻololi ʻana, a

Hoʻemi ʻia ke ola luhi o ka lāʻau.

No laila, hoʻohana ʻia ka honing e:

Loaʻamicron -like pololeima ke anawaena, ka poepoe, a me ka pololei.

Hoʻopuka ahoʻopau ʻili i hoʻomalu ʻiame kahi ʻōniʻoniʻo kikoʻī a me ke ʻano kikoʻī.

Wehe i nā distortions ili a me ka wili ʻana i ke ahi.

Hoʻomaikaʻi i kahaawe -ilikaiapaʻa lubrication.

E hoʻonui i kaka ikaika luhi a me ke pale ʻana i ke kapao ke kumu.

2. Nā Hana o ka Mīkini Honing i ka Hana Hana

3. Pehea e hoʻokō ʻia ai ke kaʻina hana hoʻonani (Step-by-Step)

KaʻAnuʻu 1: Mamua -Mīkini

ʻO nā shaftshuli, kahua kikowaena ʻole, a i ʻoleʻōniʻoniʻo ʻiai ka nui ikinui loa(e like me ka 0.02–0.1 mm).

ʻO ka pahuhopu ka waiho ʻana i kahi mea liʻiliʻi no ka honing.

ʻO ka hapa pahamālama ʻia i ka wela-.(no ka paakiki) mamua o ka pau ana.

KaʻAnuʻu Hana 2: Hoʻonohonoho & Hoʻoponopono

Kau ʻia ka lāʻauma waena o nā kikowaena a i ʻole ma kahi chuck pololeie hoomau i ka pololei pololei ma ke axis.

ʻO ka mandrel honing a lima pahaaligned coaxiallyi ke kumu.

Hiki i nā mea paʻa ke ʻae i ka lāʻaukahuli, oscillate, a noho paʻa paha, ma muli o ka hoʻolālā mīkini.

KaʻAnuʻu Hana 3: Mea hana a me Abrasive koho

No ka meahoning waho, Ho'okomo 'ia nā lima lima abrasive a i 'ole nā ​​kāma'a ma ke po'o honing e ho'onui radial a puni ke kumu.

No ka meahoning kūloko(inā loaʻa i ke kumu ka lua), hoʻohana ʻia kahi mandrel kūloko me nā pōhaku abrasive.

Nā mea abrasive maʻamau:

Aluminum Oxide a i ʻole Silicon Carbideno na kila.

CBN a i ʻole Diamondno ka huila paakiki a i ole chrome -aa i uhiia.

Honing aila a emulsion pahahāʻawi i ka lubrication, ka hoʻoluʻu, a me ka wehe ʻana i ka chip.

KaʻAnuʻu Hana 4: Honing hana

Hana ka mīkini honingnā ʻoni hoʻomalu like ʻole:

Kahuli:Hoʻololi ka lāʻau a mea hana paha ma 100-500 rpm.

Pāʻani:ʻO ka mea hana a ʻāpana paha e neʻe axially ma ka lōʻihi o ke kumu (maʻamau 10-30 m/min ka wikiwiki o ka hahau).

Pumi Radial:Hoʻohana nā kāmaʻa abrasive i ke kaomi hoʻomalu e wehe pono i nā ʻāpana microscopic o nā mea.

E hui pū ʻia kēia mau hana:

Hana i kacrosshatch patternma ka ʻilikai (ʻo ka huina maʻamau 30 degere –45 degere ).

Wehe i nā piko kiʻekiʻe a hoʻomaʻemaʻe i ke ʻano ahoʻopau pāpū.

Hoʻoponopono i nā hewa puka i hōʻiliʻili ʻia mai ka wili ʻana a i ʻole ka hoʻopili ʻana i nā distortions.

KaʻAnuʻu 5: I ka -Kaʻina Hana

Hoʻohana pinepine ʻia nā mīkini honing precisioni-nā ana a i ʻole nā ​​ʻōnaehana ana eae hahai i ke anawaena a me ka poepoe i ka manawa maoli.

Hoʻoponopono ka mana CNC i ke kaomi, ka wikiwiki, a me ka lōʻihi o ka hahau ʻana e hoʻokō i ka geometry a me ka hoʻopau.

KaʻAnuʻu Hana 6: Hope Hoʻopau Pass

Hoʻohana ʻia nā pōhaku ʻili -ʻoi aku ka maikaʻi (600–1200 grit) no nā pā hope.

ʻO ka pahuhopu he hoʻopau maʻamau ma waena o:

Ra 0.05–0.2 µmno nā kumu hydraulic a i ʻole nā ​​​​mea hoʻokele,

Rz He emi a like paha me 1 µmno ka hoʻopaʻa ʻana i nā ʻili.

Mālama kēia i ka hana lubrication kūpono a me ka liʻiliʻi o ka lole i ka wā o ka hana.

KaʻAnuʻu Hana 7: ka hoʻomaʻemaʻe a me ka nānā maikaʻi

Ma hope o ka hoʻomaʻamaʻa ʻana, loaʻa ka lāʻau:

Ultrasonic a i ʻole ka hoʻomaʻemaʻe solvente wehe i nā koena abrasive a me ka ʻaila.

Nānā metrological, me:

ʻO ke anawaena a me ka poepoe (nā ana ea a i ʻole ka mīkini ana hoʻonohonoho)

'Oka 'ilikai (profilometer)

ʻO ka pololei a me ka holo ʻana (hōʻailona kelepona a i ʻole ka hoʻoponopono laser)

ʻO nā ʻāpana wale nō e kūpono ana i nā koina pololei āpau e hele i ka plating, coating, a i ʻole hui.

4. Nā ʻāpana honi maʻamau no nā kumu pololei

5. Nā pōmaikaʻi o ka hoʻonani ʻana i ka hana ʻana i ka pololei

ʻOi aku ka maikaʻi o ka ʻili– ʻO nā ʻili pāpaʻa ʻoi aku ka maʻalahi a hoʻemi i ka ʻāwili a me ka ʻaʻahu.

ʻO ka pololei kiʻekiʻe- Hiki ke hoʻopaʻa paʻa a paheʻe paha me ka liʻiliʻi o ka ʻae.

Hoʻomaikaʻi i ka hana Sila- Mālama ʻo Crosshatch texture i nā lubricants a pale i ka leakage.

Hoʻonui i ka ikaika luhi- Wehe i nā microcracks a me nā mea hoʻoulu kaumaha mai ka wili ʻana.

Hoʻemi ʻia ka walaʻau a me ka haʻalulu- Hoʻomaikaʻi ʻia ka pololei a me ka poepoe e hoʻolalelale i ka huli ʻana.

Hoʻonui i ke ola lawelawe- ʻOi aku ka maikaʻi o ka pale ʻana o nā shafts i ka helu ʻana, ka ʻāʻī, a me ka corrosion.

6. Nā ʻano o nā mīkini honi i hoʻohana ʻia no nā shafts

7. Hōʻuluʻulu manaʻo
