Kugwiritsa ntchito Precision Granite Kuyeza

Tekinoloje yoyezera ya granite - yolondola ku micron

Granite imakwaniritsa zofunikira zaukadaulo wamakono woyezera muukadaulo wamakina.Zomwe zachitika popanga mabenchi oyezera ndi kuyesa ndikugwirizanitsa makina oyezera zawonetsa kuti granite ili ndi maubwino ake kuposa zida zakale.Chifukwa chake ndi chotere.

Kukula kwa ukadaulo woyezera m'zaka zaposachedwa ndi zaka zambiri kumakhala kosangalatsa lero.Poyambirira, njira zosavuta zoyezera monga matabwa oyezera, mabenchi oyezera, mabenchi oyesera, ndi zina zotero zinali zokwanira, koma m'kupita kwa nthawi zofunikira za khalidwe la mankhwala ndi kudalirika kwa ndondomeko zinakhala zapamwamba komanso zapamwamba.Kulondola kwa kuyeza kumatsimikiziridwa ndi geometry yoyambira ya pepala lomwe lagwiritsidwa ntchito komanso kusatsimikizika kwa muyeso wa kafukufukuyo.Komabe, ntchito zoyezera zikukhala zovuta komanso zamphamvu, ndipo zotsatira zake ziyenera kukhala zolondola.Izi zikuwonetsa kuyambika kwa spatial coordinate metrology.

Kulondola kumatanthauza kuchepetsa kukondera
Makina oyezera a 3D ali ndi dongosolo loyikira, njira yoyezera kwambiri, masensa osinthira kapena kuyeza, makina owunikira ndi pulogalamu yoyezera.Kuti mukwaniritse kulondola kwakukulu, kupotoka kwa muyeso kuyenera kuchepetsedwa.

Cholakwika choyezera ndi kusiyana pakati pa mtengo womwe umasonyezedwa ndi chida choyezera ndi mtengo weniweni wa geometric quantity (calibration standard).Cholakwika choyezera kutalika E0 cha makina oyezera amakono (CMMs) ndi 0.3+L/1000µm (L ndi kutalika kwake).Mapangidwe a chipangizo choyezera, kafukufuku, njira yoyezera, chogwirira ntchito ndi wogwiritsa ntchito ali ndi chikoka chachikulu pakupatuka kwa kuyeza kwa kutalika.Kupanga kwamakina ndiye chinthu chabwino kwambiri komanso chokhazikika chomwe chimalimbikitsa.

Kugwiritsa ntchito granite mu metrology ndi chimodzi mwazinthu zofunika zomwe zimakhudza kapangidwe ka makina oyezera.Granite ndi chinthu chabwino kwambiri pazofunikira zamakono chifukwa chimakwaniritsa zofunikira zinayi zomwe zimapangitsa kuti zotsatira zake zikhale zolondola:

1. Kukhazikika kwakukulu kwachibadwa
Granite ndi thanthwe lamapiri lomwe limapangidwa ndi zigawo zitatu zazikulu: quartz, feldspar ndi mica, zopangidwa ndi crystallization ya miyala imasungunuka mu kutumphuka.
Pambuyo pa zaka zikwi zambiri za "kukalamba", granite imakhala ndi mawonekedwe ofanana komanso opanda nkhawa zamkati.Mwachitsanzo, impala zakhala zaka pafupifupi 1.4 miliyoni.
Granite ili ndi kuuma kwakukulu: 6 pa sikelo ya Mohs ndi 10 pa sikelo ya kuuma.
2. Kukana kutentha kwakukulu
Poyerekeza ndi zitsulo zachitsulo, granite ili ndi coefficient yocheperapo yowonjezera (pafupifupi 5µm/m*K) ndi kutsika kocheperako (monga chitsulo α = 12µm/m*K).
Kutsika kwa kutentha kwa granite (3 W / m * K) kumatsimikizira kuyankha pang'onopang'ono kusinthasintha kwa kutentha poyerekeza ndi zitsulo (42-50 W / m * K).
3. Zabwino kwambiri zochepetsera kugwedezeka
Chifukwa cha mawonekedwe a yunifolomu, granite ilibe kupsinjika kotsalira.Izi zimachepetsa kugwedezeka.
4. Sitima yapamtunda yolumikizana katatu yolondola kwambiri
Granite, yopangidwa ndi miyala yolimba yachilengedwe, imagwiritsidwa ntchito ngati mbale yoyezera ndipo imatha kupangidwa bwino kwambiri ndi zida za diamondi, zomwe zimapangitsa kuti magawo amakina akhale olondola kwambiri.
Mwa kugaya pamanja, kulondola kwa njanji zowongolera kumatha kukonzedwa mpaka pamlingo wa micron.
Pa akupera, katundu amadalira mbali deformations akhoza kuganiziridwa.
Izi zimapangitsa kuti pakhale malo oponderezedwa kwambiri, kulola kugwiritsa ntchito zilolezo zonyamula mpweya.Maupangiri onyamula mpweya ndi olondola kwambiri chifukwa chapamwamba kwambiri komanso kusalumikizana kwa shaft.

Pomaliza:
Kukhazikika kwachilengedwe, kukana kutentha, kugwedera kugwedera komanso kulondola kwa njanji yowongolera ndi zinthu zinayi zazikulu zomwe zimapangitsa granite kukhala chinthu choyenera kwa CMM.Granite imagwiritsidwa ntchito kwambiri popanga mabenchi oyezera ndi kuyesa, komanso ma CMM poyesa matabwa, matebulo oyezera ndi zida zoyezera.Granite imagwiritsidwanso ntchito m'mafakitale ena, monga zida zamakina, makina a laser ndi machitidwe, makina opangira ma micromachining, makina osindikizira, makina owoneka bwino, makina opangira msonkhano, ma semiconductor processing, etc.
