Thaum lub sij hawm centerless sab nraud cylindrical sib tsoo, lub workpiece yog positioned nyob nruab nrab ntawm cov kev taw qhia log thiab lub sib tsoo log. Ib qho ntawm cov log no yog siv rau kev sib tsoo, thaum lwm qhov, hu ua lub log qhia, yog lub luag haujlwm rau kev xa cov lus tsa suab. Qhov qis ntawm lub workpiece yog txhawb los ntawm kev txhawb nqa phaj. Lub log qhia yog tsim los ntawm cov khoom siv roj hmab, thiab nws cov axis yog inclined ntawm lub kaum sab xis θ nrog rau kev sib tsoo log nyob rau hauv txoj kev ntsug. Qhov kev teeb tsa no tsav lub workpiece tig thiab pub rau hauv cov txheej txheem sib tsoo.
Kev sib tsoo ntau yam ntawm qhov tsis muaj qhov sib tsoo thiab lawv cov txheej txheem tshem tawm tau sau tseg raws li hauv qab no:
1. Qhov chaw tawm ntawm qhov chaw
Ua rau
- Lub log qhia tsis muaj qhov sib npaug.
- Muaj ob peb lub voj voog sib tsoo, lossis qhov ellipticity los ntawm cov txheej txheem dhau los yog qhov loj heev.
- Lub log sib tsoo yog npub.
- Kev sib tsoo lossis txiav ntau dhau.
Txoj kev tshem tawm
- Rov tsim kho lub log qhia thiab tos kom txog thaum nws zoo sib npaug. Feem ntau, nws yuav nres thaum tsis muaj suab nrov.
- Kho cov lej sib tsoo raws li xav tau.
- Rebuild lub sib tsoo log.
- Txo cov nyiaj sib tsoo thiab rov txiav ceev.
2. Qhov chaw muaj ntug (polygons)
Ua rau muaj teeb meem:
- Qhov nruab nrab qhov siab ntawm qhov tsis txaus.
- Ntau dhau axial thrust ntawm qhov ua rau nws nias tawm tsam tus pin nres, tiv thaiv kev sib hloov.
- Lub log sib tsoo tsis sib npaug.
- Qhov chaw ntawm qhov chaw yog positioned siab dhau.
Txoj kev tshem tawm:
- Kho qhov nruab nrab ntawm qhov raug.
- Txo qhov inclination ntawm lub grinder qhia log mus rau 0.5 ° lossis 0.25 °. Yog tias qhov no tsis daws qhov teeb meem, xyuas qhov sib npaug ntawm qhov fulcrum.
- Xyuas kom lub log sib tsoo yog sib npaug.
- Tsim nyog txo qhov nruab nrab qhov siab ntawm ib feem.
3. Cov cim vibration ntawm qhov chaw (piv txwv li, cov ntses me me thiab cov kab dawb ncaj ncaj tshwm rau ntawm qhov chaw)
Ua rau
- Lub tshuab vibration tshwm sim los ntawm qhov tsis sib npaug ntawm qhov sib tsoo lub log
- Ib feem chaw txav mus rau pem hauv ntej thiab ua rau ib feem dhia
- Lub sib tsoo lub log yog blunt, los yog nto ntawm lub sib tsoo log yog du heev
- Kev taw qhia lub log tig nrawm dhau
Tshem tawm txoj kev
- Ua tib zoo sib npaug ntawm lub log sib tsoo
- Tsim nyog txo qhov nruab nrab ntawm ib feem
- Sib tsoo lub log los yog tsim nyog ua kom qhov hnav khaub ncaws ceev ntawm lub log sib tsoo
- Tsim nyog txo cov lus qhia ceev
4. Cov khoom muaj taper
Ua rau
- Sab pem hauv ntej ntawm ib feem yog me dua vim hais tias ob qho tib si pem hauv ntej phau ntawv qhia phaj thiab phau ntawv qhia log lub generatrix yog positioned qis dhau los yog pem hauv ntej phau ntawv phaj yog qaij rau ntawm lub log qhia.
- Lub qab ntug ntawm lubCNC machining aluminium qhov chawyog me dua vim hais tias ob qho tib si saum npoo ntawm daim ntawv qhia nram qab yog qis dua li cov ntawv qhia log lub generatrix los yog lub tsheb qhia phaj yog qaij rau ntawm lub log qhia.
- Sab pem hauv ntej lossis sab nraub qaum ntawm qhov yuav muaj qhov taper rau cov laj thawj hauv qab no:
① Lub log sib tsoo muaj taper vim hnav tsis zoo
② Kev sib tsoo lub log thiab cov lus qhia log nto yog hnav
Txoj kev tshem tawm
- Ua tib zoo reposition rau pem hauv ntej phau ntawv qhia phaj thiab xyuas kom meej tias nws yog parallel rau lub generatrix ntawm phau ntawv qhia log.
- Kho cov lus qhia saum npoo ntawm daim ntawv qhia nram qab kom nws sib npaug mus rau lub generatrix ntawm cov lus qhia log thiab ua raws tib txoj kab.
① Raws li cov kev taw qhia ntawm qhov taper, kho lub kaum sab xis ntawm kev sib tsoo log hauv kev sib tsoo log hloov
② Lub log sib tsoo thiab lub log qhia
5. Qhov nruab nrab ntawm qhov yog qhov loj, thiab ob qhov kawg yog me me
Ua rau:
- Cov ntawv qhia pem hauv ntej thiab nram qab yog tilted sib npaug rau lub log sib tsoo.
- Lub log sib tsoo tau zoo li lub duav nruas.
Txoj kev tshem tawm:
- Kho cov ntawv qhia pem hauv ntej thiab nram qab.
- Hloov kho lub log sib tsoo, kom ntseeg tau tias tsis muaj nyiaj ntau dhau thaum lub sijhawm hloov kho.
6. Muaj cov xov ncig ntawm qhov chaw
Ua rau
- Cov ntawv qhia pem hauv ntej thiab nram qab protrude los ntawm cov ntawv qhia lub log, ua rau cov khoom tawg los ntawm cov npoo ntawm lub log ntawm ob qho tib si nkag thiab tawm.
- Daim ntawv qhia yog mos heev, uas tso cai rau kev sib tsoo chips los ua rau hauv cov lus qhia saum npoo, tsim cov burrs protruding uas engraving xov kab ntawm qhov chaw.
- Lub coolant tsis huv thiab muaj chips lossis xuab zeb.
- Vim muaj kev sib tsoo ntau dhau ntawm kev tawm, ntug ntawm lub log sib tsoo ua rau khawb.
- Qhov nruab nrab ntawm qhov nruab nrab yog qis dua qhov nruab nrab ntawm kev sib tsoo lub log, uas ua rau lub siab ntsug siab ua rau cov xuab zeb thiab cov chips lo rau cov lus qhia bristles.
- Lub log sib tsoo yog blunt.
- Cov khoom siv ntau dhau yog hauv av ib zaug, lossis lub log sib tsoo yog qhov ntxhib dhau, uas ua rau cov xov xov zoo heev ntawm qhov chawCNC tshuab dhos qhov chaw.
Txoj kev tshem tawm
- Kho cov ntawv qhia pem hauv ntej thiab nram qab.
- Hloov cov ntawv qhia bristles nrog lubricated cov ntaub ntawv ntawm hardness dua.
- Hloov lub coolant.
- Round ntawm ntug ntawm lub log sib tsoo, kom ntseeg tau tias kwv yees li 20 hli ntawm qhov tawm ntawm qhov yog sab laug tsis muaj av.
- Kho qhov nruab nrab qhov siab ntawm qhov kom zoo.
- Xyuas kom lub log sib tsoo nyob rau hauv qhov zoo.
- Txo cov nyiaj sib tsoo thiab ua kom qeeb ntawm kev hloov kho ceev.
7. Ib qho me me raug txiav tawm ntawm lub hauv ntej ntawm ib feem
Ua rau
- Cov ntawv qhia pem hauv ntej txuas dhau ntawm qhov chaw ntawm lub log.
- Muaj qhov tsis sib xws tseem ceeb ntawm lub hauv ntej ntawm lub log sib tsoo thiab lub log qhia.
- Kev sib tsoo ntau dhau yog tshwm sim ntawm qhov nkag.
Kev daws:
- Me ntsis reposition daim ntawv qhia pem hauv ntej rov qab.
- Hloov lossis hloov kho qhov ntev ntawm ob lub ntsiab lus.
- Txo qhov sib tsoo ntawm qhov nkag.
8. Qhov nruab nrab lossis tus Tsov tus tw ntawm ib feem raug txiav tsis zoo. Muaj ntau ntau hom kev txiav:
1. Qhov txiav yog duab plaub
Ua rau
- Daim ntawv qhia nram qab tsis sib haum nrog lub ntsej muag ntawm lub log, uas tiv thaiv ib feem ntawm kev tig thiab nres kev sib tsoo ntawm qhov chaw tread.
- Lub nraub qaum txhawb nqa tau ncua deb dhau, ua rau hauv av ib feem nyob rau hauv qhov chaw thiab tiv thaiv nws los ntawm kev tig lossis txav mus rau pem hauv ntej.
Tshem tawm
- Kho daim ntawv qhia nram qab rau txoj haujlwm kom raug.
- Reinstall lub ncoo txhawb nqa.
2. Qhov kev txiav yog angular lossis muaj ntau cov cim micro-puab
Ua rau
- Lub tsheb qhia phaj lags qab ntawm qhov chaw ntawm lub log tsheb
- Qhov nruab nrab ntawm qhov txav siab dhau lawm, ua rau qhov chaw dhia ntawm qhov tawm
Tshem tawm
- Txav lub phaj qhia nram qab me ntsis rau pem hauv ntej
- Txhim kho qhov siab ntawm qhov nruab nrab ntawm ib feem
9. Qhov ci ci ntawm qhov chaw tsis yog xoom
Ua rau
- Lub inclination ntawm phau ntawv qhia log yog ntau dhau, ua rau ib feem txav mus sai heev.
- Lub log sib tsoo tau hloov sai heev, ua rau lub ntsej muag du.
- Tsis tas li ntawd, lub log qhia tau hloov kho ib yam nkaus.
Kev daws
- Txo lub kaum sab xis ntawm inclination.
- Txo qhov kev hloov kho ceev thiab pib hloov kho cov kev sib tsoo ntawm qhov pib.
- Reconstruct lub log qhia.
Nco tseg: Thaum lub log sib tsoo tsis ua haujlwm, nws yog txwv tsis pub qhib lub coolant. Yog tias lub coolant yuav tsum tau qhib ua ntej kom tsis txhob muaj qhov yuam kev tshwm sim, nws yuav tsum tau qhib thiab tawm tsis tu ncua (piv txwv li, on, off, on, off). Tos kom lub coolant tawg tawm ntawm txhua sab ua ntej pib ua haujlwm.
