Nyob rau hauv cov khoom siv CNC yuav tsum tsis txhob siv granite roj bearings?

Granite roj bearings yog dav siv los ua cov khoom siv hauv CNC khoom.Nws yog lub npe hu rau nws cov khoom zoo xws li siab tawv, siab load peev xwm, thiab tsawg thermal expansion.Txawm li cas los xij, muaj qee yam khoom siv CNC uas yuav tsum tsis txhob siv cov roj av granite.

Ib yam khoom siv zoo li no yog CNC tshuab uas xav tau kev ua haujlwm siab.Granite gas bearings tsis haum rau kev ua haujlwm siab vim tias lawv tsis muab qhov xav tau ntawm qhov raug.Qhov no yog vim qhov chaw sib cuag ntawm granite gas bearing thiab spindle tsis sib xws.Qhov chaw tiv tauj yog ua los ntawm cov hnab ntim me me ntawm cov pa roj uas tsim cov yeeb yaj kiab roj ntawm ob qhov chaw.

Nyob rau hauv high precision CNC tshuab, yuav tsum muaj ib theem siab ntawm qhov tseeb yog yuav tsum tau rau lub lag luam ntawm lub tshuab.Yog li ntawd, lwm hom bearings yog siv los muab cov qib uas yuav tsum tau muaj, xws li ceramic lossis hlau bearings.

Lwm yam khoom siv CNC qhov twg granite roj bearings yuav tsum tsis txhob siv yog nyob rau hauv cov cav tov uas yuav tsum tau ib tug siab ntawm thermal stability.Granite gas bearings tsis haum rau cov ntawv thov uas muaj qhov sib txawv ntawm qhov kub thiab txias.Qhov no yog vim granite muaj cov thermal expansion coefficient siab, uas txhais tau hais tias nws nthuav thiab cog lus nrog qhov kub thiab txias.

Nyob rau hauv cov cav tov uas yuav tsum tau ib tug siab ntawm thermal stability, lwm yam bearings yog siv uas tsis muaj thermal expansion coefficients.Cov no suav nrog cov ntaub ntawv xws li ceramics lossis hlau.

Granite roj bearings yog tshwj xeeb tshaj yog haum rau daim ntaub ntawv uas muaj cov loads nruab nrab thiab nruab nrab ntawm precision yuav tsum tau.Hauv hom kev thov no, lawv muab kev ua haujlwm zoo thiab ua haujlwm ntev.

Hauv kev xaus, granite gas bearings yog cov khoom siv ntau yam uas tuaj yeem siv rau hauv ntau yam khoom siv CNC.Txawm li cas los xij, lawv tsis haum rau cov ntawv thov siab precision lossis cov cav tov uas yuav tsum tau muaj cov thermal stability siab.Nyob rau hauv cov ntaub ntawv no, lwm yam bearings yuav tsum tau siv uas muab qhov yuav tsum tau cov theem ntawm qhov tseeb thiab thermal stability.
