Lwm cov txheej txheem kev cai rau kev sib sib zog nqus qhov drilling thiab tho txawv cav
Qhov sib sib zog nqus qhov tho txawv thiab tho txawv cav yog ib yam khoom siv kho tshuab. Yuav kom ua tau zoo dua rau qhov kev xav tau ntawm engineering, cov khoom siv yog ncaj qha raws li tus txheej txheem tsim hauv kev tsim thiab siv thiab ua. Dab tsi yog qhov yuav tsum ua raws li kev cai?
Feem ntau, peb muaj cov lus ntau dua rau qhov kev txiav txim siab ntawm qhov sib sib zog nqus qhov drilling thiab tho qhov cav, feem ntau yog plaub yam: 1. qhov chaw npoo av, feem ntau qhov yuav tsum yog R alpha 1.6 ~ 0.4 micron. 2. Cov duab zoo, qhov cylindrical qhov zoo tshaj plaws, yuav tsum yog feem ntau nyob rau hauv lub siab kam, siab precision qhov, cov duab zoo yuav tsum tswj tau lub siab kam rau siab 1/2 ~ 1/3. 3. qhov muaj qhov loj, qhov loj lub qhov los yog kev tuav qhov siab kam rau siab ntawm qhov sib sib zog nqus qhov cav, feem ntau yuav tsum tau tswj hauv IT7 ~ IT8, qhov tseem ceeb ntawm lub qhov yog tshuab spindle box tswj hauv IT6, lwm qhov xav tau tsawg tsawg, dav IT11. 4. txoj hauj lwm kev txiav txim, qhov teeb meem ntawm qhov teeb meem (nrog rau kev ua yuam kev sib haum ntawm coaxial qhov), feem ntau tswj hauv + / - 0.025 --0.025 hli; vertical error: 0.01 ~ 0.05 / h 200; parallelism yuam kev, kev tswj hauv 0.03 ~ 0.10 hli.
Los ntawm cov lus saum toj no, peb muaj kev nkag siab txog qhov kev xav tau rau qhov tseeb ntawm kev sib sib zog nqus qhov tho txawv thiab tho tshuab. Yog tias koj xav paub ntxiv, thov ua tib zoo mloog qhov kev piav qhia ntxiv.
