Ka hoʻomaopopo ʻana i ka Elastic Modulus o Precision Granite Surface Plates a me kāna kuleana i ka Deformation Resistance

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 e wehewehe ana i ka hana o ka pā pōhaku pōhaku ʻo kona Elastic Modulus - kahi ana pili pono i ka hiki o ka mea ke pale i ka deformation ma lalo o ka ukana.

He aha ka Elastic Modulus?

Hōʻike ka Elastic Modulus (ʻike pū ʻia ʻo Young's Modulus) i ka ʻoʻoleʻa o kahi mea. He ana ia i ka pilina ma waena o ke koʻikoʻi (ka ikaika o kēlā me kēia ʻāpana) a me ke kānana (deformation) i loko o ka laulā elastic o ka mea. Ma nā huaʻōlelo maʻalahi, ʻoi aku ka kiʻekiʻe o ka modulus elastic, ʻoi aku ka liʻiliʻi o ka deforms o kahi mea ke kau ʻia kahi ukana.

No ka laʻana, ke kākoʻo ka pā pōhaku ʻili i kahi mea ana kaumaha, ʻoi aku ka ʻoi aku o ka modulus elastic e hōʻoia i ka mālama ʻana o ka pā i kona palahalaha a me kona kūpaʻa - nā mea koʻikoʻi no ka mālama pono ʻana i ke ana pono.

Granite vs. Nā Mea Hana ʻē aʻe

Hoʻohālikelike ʻia me nā mea e like me ke kinikini, ka hao, a i ʻole ka polymer concrete, ZHHIMG® black granite he modulus elastic kiʻekiʻe loa, maʻamau mai ka 50-60 GPa, e hilinaʻi ana i ka haku mele a me ka nui. ʻO ia ke ʻano o ka pale ʻana i ke kuʻi ʻana a i ʻole ke kaua ʻana ma lalo o nā haʻahaʻa mīkini koʻikoʻi, i mea kūpono no nā paepae kiʻekiʻe a me nā kumu mīkini.

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

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

ʻO ke kūʻē ʻana o ka pā pōhaku i ka deformation e hoʻoholo i ka pololei o ka hiki ke lawelawe ma ke ʻano he mokulele kuhikuhi.

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

• He kōkua nō hoʻi i ka mālama ʻana i ka palahalaha lōʻihi, ʻoi aku hoʻi i nā paepae ʻano nui i hoʻohana ʻia no nā mīkini CNC, nā mīkini ana hoʻonohonoho (CMMs), a me nā ʻōnaehana nānā semiconductor.

• Hoʻohui pū ʻia me ka hoʻonui wela haʻahaʻa o ka granite a me nā waiwai damping maikaʻi loa, ʻo kēia ka hopena i ke kūpaʻa o ka nui o ka manawa.

ʻO ka pono kūpono o ZHHIMG®

Ma ZHHIMG®, hana ʻia nā paepae granite pololei a pau mai ka granite ʻeleʻele ZHHIMG® kiʻekiʻe (≈3100 kg/m³), e hāʻawi ana i ka ʻoʻoleʻa maikaʻi a me ka paʻa lōʻihi. Hoʻopili maikaʻi ʻia kēlā me kēia papa honua e nā ʻenehana loea - ʻo kekahi me 30 mau makahiki o ka ʻike wili lima - e hoʻokō i ka pololei o ka sub-micron flatness. Hoʻopili kā mākou kaʻina hana i nā kūlana DIN 876, ASME B89, a me GB, e hōʻoia ana i kēlā me kēia huahana e hoʻokō a ʻoi aku paha i nā koi metrology honua.

Ka hopena

ʻAʻole ʻo ka modulus elastic wale nō kahi ʻāpana ʻenehana - he kumu wehewehe ia no ka hilinaʻi o nā ʻāpana granite precision. ʻO ka modulus kiʻekiʻe ke ʻano o ka ʻoʻoleʻa, ʻoi aku ka maikaʻi o ke kūpaʻa deformation, a ʻo ka hopena, ʻoi aku ka pololei o ke ana ʻana.
ʻO ia ke kumu i hilinaʻi ʻia ai nā papa ʻāina granite ZHHIMG® e nā alakaʻi alakaʻi honua a me nā keʻena metrology no nā noi kahi hiki ʻole ke hoʻololi i ka pololei.
