Koj puas paub yim qhov ua txhaum ntawm cov ntxaiv ntawm lub chaw machining thiab cov txheej txheem kev kho mob?

I. Kev Taw Qhia

II. Tej Faults thiab Troubleshooting Methods rau Spindle ntawm Machining Centers

(I) Ua tsis tau raws li qhov yuav tsum tau ua kom raug

• Thaum lub sij hawm kev thauj mus los, cov cuab yeej siv lub tshuab yuav raug cuam tshuam, uas tuaj yeem ua rau qhov tseeb ntawm cov khoom siv spindle. Piv txwv li, lub axis ntawm spindle yuav hloov, thiab cov kabmob vaj tse yuav deform.
• Lub installation tsis ruaj khov, qhov tseeb installation yog tsawg, lossis muaj kev hloov pauv. Ib qho tsis sib xws ntawm lub hauv paus ntawm lub tshuab cuab yeej, xoob lub hauv paus bolts, los yog kev hloov hauv qhov tseeb ntawm kev teeb tsa vim lub hauv paus kev daws teeb meem thiab lwm yam laj thawj ntawm kev siv mus sij hawm ntev tuaj yeem cuam tshuam rau tus txheeb ze qhov tseeb ntawm qhov ntxaiv thiab lwm yam khoom, uas ua rau poob ntawm kev ua haujlwm raug.

• Rau cov cuab yeej siv tshuab cuam tshuam thaum lub sijhawm thauj mus los, yuav tsum muaj kev tshuaj xyuas qhov tseeb ntawm cov spindle Cheebtsam, suav nrog cov ntsuas xws li radial runout, axial runout, thiab coaxiality ntawm spindle. Raws li kev soj ntsuam xyuas, cov kev hloov kho kom tsim nyog, xws li kho cov kabmob clearance thiab kho cov kabmob vaj tse, raug saws los kho qhov tseeb ntawm cov spindle. Yog tias tsim nyog, cov kws tshaj lij tshuab cuab yeej tu cov neeg ua haujlwm tuaj yeem raug caw tuaj kho.
• Tsis tu ncua xyuas cov xwm txheej ntawm lub tshuab cuab yeej thiab ua kom lub hauv paus bolts kom ruaj khov. Yog tias muaj kev hloov pauv hauv qhov raug pom, cov cuab yeej nrhiav kom pom tseeb yuav tsum tau siv los kho qhov qib ntawm cov cuab yeej siv tshuab thiab cov txheeb ze qhov tseeb ntawm cov ntxaiv thiab cov khoom xws li lub rooj ua haujlwm.
