Cov khoom siv feem ntau ntawm CMM

Nrog rau kev txhim kho ntawm lub tshuab ntsuas kev sib koom tes (CMM) thev naus laus zis, CMM tau siv ntau thiab ntau dua.Vim tias cov qauv thiab cov khoom siv ntawm CMM muaj kev cuam tshuam zoo rau qhov raug, nws yuav tsum tau ua ntau thiab ntau dua.Hauv qab no yog qee yam khoom siv hauv tsev.

1. Cam khwb cia hlau

Cam khwb cia hlau yog ib hom khoom siv siv ntau, feem ntau yog siv rau hauv paus, zawv zawg thiab dov phau ntawv qhia, kab, kev txhawb nqa, thiab lwm yam. Nws muaj qhov zoo ntawm me me deformation, zoo hnav tsis kam, ua haujlwm yooj yim, tsis tshua muaj nqi, linear expansion yog ze tshaj plaws. rau coefficient ntawm qhov chaw (steel), Nws yog cov khoom siv thaum ntxov.Hauv qee lub tshuab ntsuas tseem siv cov khoom siv hlau cam khwb cia.Tab sis nws kuj muaj qhov tsis zoo: cam khwb cia hlau yog qhov cuam tshuam rau corrosion thiab abrasion tsis kam yog qis dua granite, nws lub zog tsis siab.

2. Hlau

Hlau yog tsuas yog siv rau lub plhaub, kev txhawb nqa qauv, thiab qee qhov ntsuas tshuab puag kuj siv hlau.Feem ntau siv cov pa roj carbon tsawg, thiab yuav tsum tau kho cua sov.Qhov zoo ntawm cov hlau yog zoo rigidity thiab lub zog.Nws qhov tsis xws luag yog qhov yooj yim rau deformation, qhov no yog vim cov hlau tom qab ua tiav, cov kev ntxhov siab nyob hauv qhov tso tawm ua rau deformation.

3. Granite

Granite yog sib dua li hlau, hnyav dua li txhuas, nws yog cov khoom siv ntau.Lub ntsiab kom zoo dua ntawm granite yog me ntsis deformation, zoo stability, tsis xeb, yooj yim los ua graphic ua, flatness, yooj yim mus cuag platform siab tshaj cam khwb cia hlau thiab haum rau zus tau tej cov high precision qhia.Tam sim no ntau CMM tau txais cov khoom siv no, lub rooj zaum ua haujlwm, tus ncej choj, cov ncej qhia kev tsheb nqaj hlau thiab Z axis, tag nrho ua los ntawm granite.Granite tuaj yeem siv los ua workbench, square, kem, beam, qhia, kev txhawb nqa, thiab lwm yam Vim yog lub thermal expansion coefficient me me ntawm granite, nws yog qhov tsim nyog rau kev koom tes nrog air-flotation guide rail.

Granite kuj muaj qee qhov tsis zoo: txawm hais tias nws tuaj yeem ua los ntawm cov qauv hollow los ntawm pasting, nws yog qhov nyuaj dua;Cov khoom siv zoo yog qhov loj, tsis yooj yim rau txheej txheem, tshwj xeeb tshaj yog cov ntsia hlau qhov nyuaj rau kev ua, raug nqi ntau dua li cov hlau cam khwb cia;Granite cov ntaub ntawv yog nkig, yooj yim rau lub cev qhuav dej thaum lub machining ntxhib;

4. Ceramic

Ceramic yog tsim sai heev nyob rau hauv xyoo tas los no.Nws yog cov khoom siv ceramic tom qab compacting sintering, regrinding.Nws cov yam ntxwv yog ntxeem tau, qhov zoo yog lub teeb (qhov ceev yog kwv yees li 3g / cm3), lub zog siab, kev ua haujlwm yooj yim, zoo abrasion tsis kam, tsis xeb, haum rau Y axis thiab Z axis qhia.Qhov tsis zoo ntawm ceramic yog tus nqi siab, kev siv thev naus laus zis siab dua, thiab kev tsim khoom yog qhov nyuaj.

5. Aluminium alloy

CMM feem ntau yog siv high-strength aluminium alloy.Nws yog ib qho kev loj hlob sai tshaj plaws nyob rau xyoo tas los no.Aluminium muaj qhov zoo ntawm lub teeb yuag, siab zog, me me deformation, thermal conduction kev ua tau zoo, thiab tuaj yeem nqa tawm vuam, haum rau kev ntsuas tshuab ntawm ntau qhov chaw.Daim ntawv thov ntawm lub zog siab aluminium alloy yog qhov tseem ceeb ntawm qhov tam sim no.
