Nā Kūlana Granite

1. ʻO ke koina kūpaʻa wela haʻahaʻa loa: I ke kaʻina hana ana, ʻo ka hoʻoili wela mai ka lima a i ʻole nā ​​​​hoʻoponopono iki ʻana i ka mahana ambient he hopena liʻiliʻi loa ia i ka nui o ka granite, e hōʻoiaʻiʻo ana ʻaʻole e neʻe ka kuhikuhi i ka wā o ka hana micron-level o ka ʻike ʻana i ka parallelism.

2. ʻAʻohe hoʻololi elastic ma lalo o ke kaumaha: ʻAʻole e like me nā straightedges metala, ʻaʻole hōʻike ka granite i ka deformation elastic hiki ke ana ʻia—ʻoiai ma lalo o nā ikaika pili kūloko—no laila e mālama ana i ka pololei linear paʻa o ka lihi kuhikuhi ma ka mokulele kū pololei.

3. ʻAʻole magnetic a electrostatically inert: ʻO ka mea he non-ferromagnetic maoli a he liʻiliʻi ka paʻa ʻana o ka uku ʻili, e hoʻopau ana i ka pilikia o ka hoʻopili ʻana o nā particulate (e like me ka ferrous swarf a i ʻole ka lepo); pale kēia i ka hoʻokiʻekiʻe spurious o ka workpiece a hōʻoia i ka ʻoiaʻiʻo o ke ana ʻana i ka loiloi parallelism kiʻekiʻe.
