Ke hoʻomaopopo nei i ka Elastic Modulus o nā Precision Granite Surface Plates a me kāna kuleana i ke kū'ē ʻana i ka deformation

I ka wā e pili ana i ke ana pololei a me nā lako metrology, ʻo ke kūpaʻa a me ka pololei nā mea āpau. ʻO kekahi o nā waiwai mechanical koʻikoʻi e wehewehe ana i ka hana o kahi papa ʻili granite ʻo ia kona Elastic Modulus - kahi ana e pili pono ana i ka hiki o ka mea ke kū'ē i ka deformation ma lalo o ke kaumaha.

He aha ka Modulus Elastic?

ʻO ka Elastic Modulus (i ʻike ʻia hoʻi ʻo Young's Modulus) e wehewehe ana i ke ʻano o ka paʻakikī o kahi mea. Ana ia i ka pilina ma waena o ke kaumaha (ikaika no kēlā me kēia ʻāpana) a me ke kaumaha (deformation) i loko o ka pae elastic o ka mea. I nā huaʻōlelo maʻalahi, ʻo ke kiʻekiʻe o ka elastic modulus, ʻo ka emi ʻana o ka deform o kahi mea ke kau ʻia kahi ukana.

Eia kekahi laʻana, ke kākoʻo kahi papa ʻili granite i kahi mea ana kaumaha, ʻo ka modulus elastic kiʻekiʻe e hōʻoiaʻiʻo i ka mālama ʻana o ka papa i kona pālahalaha a me ke kūpaʻa o ka dimensional - nā mea koʻikoʻi no ka mālama ʻana i ka pololei o ke ana ʻana.

Granite vs. Nā Mea ʻē aʻe

Ke hoʻohālikelike ʻia me nā mea e like me ke kinikini, ka hao i hoʻolei ʻia, a i ʻole ka sima polymer, he modulus elastic kiʻekiʻe loa ko ka granite ʻeleʻele ZHHIMG®, maʻamau mai 50-60 GPa, ma muli o ka haku mele a me ka nui o ka mineral. ʻO ke ʻano kēia e kūʻē i ke kūlou ʻana a i ʻole ka warping ʻoiai ma lalo o nā ukana mechanical koʻikoʻi, e kūpono ana no nā kahua kikoʻī kiʻekiʻe a me nā kumu mīkini.

I ka hoʻohālikelike ʻana, ʻoi aku ka maʻalahi o nā mea me ka modulus elastic haʻahaʻa i ka hoʻololi elastic, hiki ke hopena i nā hewa ana maalea akā koʻikoʻi i nā noi ultra-precision.

No ke aha he mea nui ka Elastic Modulus i ka Precision Granite

ʻO ke kū'ē'ē o kahi papa granite i ka deformation e hoʻoholo ai i ka pololei o ia mea e hiki ai ke lawelawe ma ke ʻano he mokulele kuhikuhi.

• ʻO ka modulus elastic kiʻekiʻe e hōʻoiaʻiʻo i ka rigidity maikaʻi loa, e hōʻemi ana i ka pilikia o ka micro-deformation ma lalo o nā ukana kiko.

• Kōkua nō hoʻi ia i ka mālama ʻana i ka palahalaha lōʻihi, ʻoi aku hoʻi i nā kahua nui i hoʻohana ʻia no nā mīkini CNC, nā mīkini ana hoʻonohonoho (CMM), a me nā ʻōnaehana nānā semiconductor.

• I hui pū ʻia me ka hoʻonui haʻahaʻa haʻahaʻa o ka granite a me nā waiwai damping maikaʻi loa, ʻo kēia ka hopena i ka paʻa o ka dimensional i ka hala ʻana o ka manawa.

ʻO ka Pōmaikaʻi Kūpono o ZHHIMG®

Ma ZHHIMG®, hana ʻia nā kahua granite kikoʻī a pau mai ka granite ʻeleʻele ZHHIMG® kiʻekiʻe-density (≈3100 kg/m³), e hāʻawi ana i ka paʻa maikaʻi loa a me ke kūpaʻa lōʻihi. Hoʻopili maikaʻi ʻia kēlā me kēia papa ʻili e nā loea akamai - ʻo kekahi me ka ʻoi aku o 30 mau makahiki o ka ʻike wili lima - e hoʻokō i ka pololei o ka palahalaha sub-micron. Hahai kā mākou kaʻina hana i nā kūlana DIN 876, ASME B89, a me GB, e hōʻoiaʻiʻo ana ua hoʻokō a ʻoi aku paha kēlā me kēia huahana i nā koi metrology honua.

Hopena

ʻAʻole wale ka modulus elastic he palena loea - he kumu ia e wehewehe ai i ka hilinaʻi o nā ʻāpana granite precision. ʻO ke modulus kiʻekiʻe aʻe ke ʻano o ka paʻakikī nui, ka pale ʻana i ka deformation maikaʻi, a ʻo ka hope loa, ʻoi aku ka pololei o ke ana ʻana.
ʻO ia ke kumu i hilinaʻi ʻia ai nā papa ʻili granite ZHHIMG® e nā mea hana honua alakaʻi a me nā ʻoihana metrology no nā noi kahi hiki ʻole ke hoʻopilikia ʻia ka pololei.
