Vim tias cov hla kev uas sib kis tau los ntawm qhov chaw loj, lawv deform tsawg dua pob reining pob khoom thiab zoo dua, tsim kom muaj ntau yam meej thiab zoo ib yam. Vim tias qhov kev siab dua no, cov thawv ntawv hla kev pabcuam yeej qhia meej meej.
Cov hla ciam av muaj tsawg dua kev zam ntawm qhov chaw ntom ntom saum npoo tsis zoo dua pob reavulating pob bearings vim lawv rigidity thiab txoj kev lawv tsim. Pob Bearings muaj peev xwm kov tau cov kev ua txhaum ntawm qhov kev txiav txim ntawm tsib mus rau kaum 10 microns thaum hla kev tawm ntawm cov menyuam yaus yuav tsum tau ua kom tsawg tshaj ob lub microns rau ultra precision.
