Thaum PCB drilling thiab milling, qhov kub thiab txias ntawm cov khoom granite yog dab tsi?

Cov khoom siv granite tau dhau los ua neeg nyiam heev hauv kev tsim thiab kev tsim kho ntawm PCB drilling thiab milling tshuab. Qhov no yog vim lawv muaj peev xwm tiv taus qhov kub siab uas tsim thaum lub sijhawm machining yam tsis poob lawv cov qauv. Kev siv cov khoom siv granite hauv PCB drilling thiab milling tshuab ua rau muaj qhov tseeb, qhov tseeb thiab qhov ceev ntawm cov txheej txheem ua rau cov khoom zoo kawg.

Qhov kub thiab txias ntawm cov khoom siv granite siv rau hauv PCB drilling thiab milling tshuab yog nyob ntawm ntau yam. Cov yam no suav nrog hom granite siv, qhov tuab ntawm cov khoom granite, qhov ceev ntawm drilling lossis milling, thiab qhov tob thiab qhov loj ntawm lub qhov uas raug machined.

Feem ntau, granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws yuav tiv taus deformation thiab kev puas tsuaj los ntawm qhov kub siab. Tsis tas li ntawd, granite muaj peev xwm thermal siab, uas tso cai rau nws nqus cua sov thiab tswj qhov kub thiab txias tas li. Qhov no ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv hauv PCB drilling thiab milling tshuab, qhov twg kub siab raug tsim thaum lub sijhawm machining.

Feem ntau cov khoom siv granite siv rau hauv PCB drilling thiab milling tshuab muaj qhov kub thiab txias sib txawv ntawm 20 ℃ txog 80 ℃. Txawm li cas los xij, qhov no tuaj yeem sib txawv nyob ntawm hom granite siv. Piv txwv li, granite dub, uas muaj peev xwm thermal siab dua, tuaj yeem tiv taus qhov kub siab dua piv rau cov xim granite sib dua.

Ntxiv rau qhov kub thiab txias sib txawv, qhov tuab ntawm cov khoom granite kuj yog ib qho tseem ceeb uas yuav tsum xav txog. Cov khoom granite tuab dua tuaj yeem nqus cua sov zoo dua thiab tswj qhov kub thiab txias ruaj khov thaum lub sijhawm ua haujlwm. Qhov no ua kom ntseeg tau tias qhov tseeb thiab qhov tseeb ntawm PCB drilling thiab milling tshuab tseem nyob ruaj khov txawm tias siv ntev.

Qhov kev ceev ntawm kev khawb lossis kev sib tsoo kuj yog ib qho tseem ceeb uas yuav tsum xav txog thaum siv cov khoom granite hauv PCB drilling thiab milling machines. Qhov kev ceev ntawm kev khawb lossis kev sib tsoo siab ua rau muaj cua sov ntau dua, uas tuaj yeem ua rau puas tsuaj rau cov khoom granite. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tswj qhov ceev ntawm lub tshuab kom ntseeg tau tias qhov kub ntawm cov khoom granite tseem nyob ruaj khov.

Xaus lus, kev siv cov khoom granite tau hloov pauv txoj kev drilling thiab milling PCB. Lawv ruaj khov thiab tuaj yeem tiv taus qhov kub siab yam tsis muaj kev puas tsuaj. Qhov kub sib txawv ntawm cov khoom granite siv hauv PCB drilling thiab milling tshuab yog ntawm 20 ℃ txog 80 ℃, nyob ntawm qhov tuab thiab hom granite siv. Nrog cov ntaub ntawv no, cov engineers thiab cov kws kho tshuab tuaj yeem xaiv cov khoom granite zoo rau lawv cov PCB drilling thiab milling tshuab kom ua tau zoo tshaj plaws thiab ua tiav cov khoom zoo kawg.
