Cov qhov ntev thiab cov lus qhia rau cov granite bases siv hauv CMMs yog dab tsi?

 

Cov hauv paus granite yog cov khoom tseem ceeb hauv ntiaj teb ntawm cov tshuab ntsuas sib koom ua ke (CMMs), muab lub platform ruaj khov thiab meej rau cov haujlwm ntsuas. Kev nkag siab txog qhov loj me thiab cov lus qhia ntawm cov hauv paus granite no yog qhov tseem ceeb kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws thiab raug hauv koj cov ntawv thov ntsuas.

Feem ntau, cov hauv paus granite muaj ntau qhov loj me, nrog rau qhov loj me uas feem ntau yog txij li 300mm x 300mm txog 2000mm x 3000mm. Qhov kev xaiv qhov loj me feem ntau yuav nyob ntawm qhov xav tau tshwj xeeb ntawm CMM thiab hom kev ntsuas uas tau ua. Cov hauv paus loj dua yog qhov tsim nyog rau kev ntsuas cov khoom loj dua, thaum cov hauv paus me dua yog qhov tsim nyog rau cov ntawv thov me dua.

Hais txog qhov tuab, cov hauv paus granite feem ntau yog 50 mm txog 200 mm. Cov hauv paus tuab dua txhim kho kev ruaj khov thiab txo qhov kev pheej hmoo ntawm kev hloov pauv thaum lub sijhawm thauj khoom, uas yog qhov tseem ceeb rau kev tswj hwm qhov tseeb ntawm kev ntsuas. Qhov hnyav ntawm cov hauv paus granite kuj yog qhov yuav tsum tau xav txog, vim tias cov hauv paus hnyav dua feem ntau muab kev nqus dej zoo dua, txhim kho qhov tseeb ntawm kev ntsuas.

Qhov tiav ntawm qhov chaw granite yog lwm qhov tseem ceeb. Qhov tiav ntawm qhov chaw CMM granite yog kwv yees li 0.5 txog 1.6 microns, ua kom muaj qhov chaw tiaj tus thiab du kom txo qhov yuam kev ntsuas. Tsis tas li ntawd, qhov kev kam rau siab ntawm qhov tiaj tus yog qhov tseem ceeb, nrog rau cov lus qhia dav dav xws li 0.01 hli txog 0.05 hli, nyob ntawm seb yuav tsum tau ua li cas.

Cov khoom siv granite nws tus kheej muaj kev ruaj khov zoo heev, kev nthuav dav thermal tsawg thiab kev tiv thaiv kev hnav, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau qhov chaw ntsuas qhov tseeb. Cov hom granite feem ntau siv rau cov mounts no suav nrog granite dub, uas nyiam vim nws ruaj khov thiab zoo nkauj.

Hauv kev xaus lus, thaum xaiv lub hauv paus granite rau CMM, qhov loj me, tuab, qhov tiav ntawm qhov chaw, thiab cov khoom siv yuav tsum tau txiav txim siab kom ntseeg tau tias qhov ntsuas tau raug thiab ntseeg tau zoo tshaj plaws.
