Cov pwm loj (xws li tsheb lub cev vaj huam sib luag pwm thiab nkoj hull pwm) tso tshwj xeeb xav tau ntawm cov cuab yeej siv tshuab vim lawv qhov loj me, hnyav hnyav, thiab cov kev xav tau nruj nruj. Hnyav -cov haujlwm kab rov tav tshuab dhos, nrog lawv cov khoom muaj zog- cov kabmob muaj peev xwm, ruaj khov machining raug, thiab cov txheej txheem hloov tau yooj yim, tau dhau los ua cov cuab yeej tseem ceeb hauv kev tsim pwm loj, thiab lawv daim ntawv thov tus nqi tau cuam tshuam rau ntau qhov tseem ceeb.
Nyob rau hauv lub pwm loj dawb paug machining theem, hnyav-lub luag haujlwm kab rov tav tshuab dhos hnyav-load machining muaj peev xwm yog qhov tshwj xeeb tshaj yog. Cov pwm no feem ntau yog castings lossis forgings hnyav kaum tawm tons, uas cov cuab yeej siv niaj hnub nyuaj los txhawb. Txawm li cas los xij, qhov hnyav - lub luag haujlwm kab rov tav tshuab dhos lub txaj siv ib qho qauv tsim, ua rau kev laus kho kom tshem tawm cov kev ntxhov siab sab hauv, thiab nws lub rooj ua haujlwm tuaj yeem nqa tau txog ntau pua tons. Ua ke nrog lub siab - lub zog chuck los yog qhov chaw, nws tuaj yeem ua tiav kev kho kom haum ntawm qhov khoob. Thaum lub sij hawm machining, lub siab torque tso tawm ntawm lub spindle tsav cov dawb paug kom tig ruaj khov, tso cai rau loj -mas txiav nrog dav -bladed cov cuab yeej, sai sai tshem tawm cov khoom ntau dhau thiab machining qhov dawb paug kom ze rau - tiav qhov ntev, ua kom lub sij hawm ua tiav tom ntej. Piv txwv li, thaum machining 5-meter txoj kab uas hla automotive lub cev vaj huam sib luag pwm thav duab, lub machining ntxhib ntawm sab nraud thiab lub ntsej muag kawg tuaj yeem ua tiav hauv ib qho kev ua haujlwm, nce kev ua haujlwm ntau dua 40% piv rau segmented machining.
Precision machining ntawm pwm tsim nto yog nyob ntawm qhov siab -kev tswj qhov muaj peev xwm ntawm lub tshuab ua haujlwm hnyav- kab rov tav. Cov txheej txheem ntawm cov pwm loj feem ntau muaj cov txheej txheem nkhaus thiab cov txheej txheem kauj ruam. Lub tshuab dhos CNC tuaj yeem ua tiav peb - qhov sib txawv ntawm kev sib cuam tshuam los ntawm ntau -axis linkage, machining curved nto contours uas ua tau raws li cov qauv tsim. Nws cov spindle siv siab -precision hydrostatic bearings, ua tiav qhov kev sib hloov ntawm 0.001mm. Ua ke nrog kaw- lub voj tawm tswv yim los ntawm cov kab tawm encoder, machining seem yuam kev tuaj yeem tswj tau ntawm qib micrometer. Txhawm rau hais txog qhov yuav tsum tau ua ntawm qhov roughness ntawm cov pwm, lub tshuab dhos tuaj yeem txhim kho qhov tsis zoo (xws li txo tus nqi pub thiab nce ntxaiv ceev) thiab muab lawv nrog siab -tiav cov cuab yeej txiav kom ua tiav qhov roughness ntawm Ra1.6μm lossis tsawg dua, txo cov haujlwm ntawm cov txheej txheem polishing tom ntej. Thaum machining lub nplhaib ntawm lub log tsheb loj, lub tshuab dhos tuaj yeem rov ua cov qauv zoo ntawm tus qauv tread, ua kom pom tseeb ntawm lub log tsheb tread qauv tom qab pwm tsim.
Machining complex qhov tshuab thiab cov qauv tsis sib xws qhia tau hais tias cov cuab yeej ua tau yooj yim. Cov pwm loj feem ntau xav tau ntau qhov chaw thiab mounting qhov ntawm lub ntsej muag kawg lossis sab. Hnyav- lub luag haujlwm kab rov tav tshuab dhos, los ntawm kev ntxiv lub zog turrets lossis milling txuas, tuaj yeem ua tiav kev sib xyaw ua ke thiab milling machining. Thaum machining eccentric qhov nyob rau hauv pwm, lub tshuab dhos qhov indexing muaj nuj nqi tso cai rau lub spindle yuav tig mus rau ib tug tshwj xeeb lub kaum sab xis thiab xauv ua ntej milling tiav los ntawm lub milling axis pub, tsis txhob muab tso rau qhov teeb meem tshwm sim los ntawm theem nrab clamping. Rau cov qauv pwm nrog keyways thiab grooves, tig thiab milling kev ua haujlwm tuaj yeem ua tiav hauv ib qho clamping, kom ntseeg tau qhov tseeb ntawm cov yam ntxwv. Qhov no ua ke machining muaj peev xwm tsis tsuas yog txhim kho machining efficiency tab sis, tseem ceeb tshaj, xyuas kom meej lub coaxiality, perpendicularity, thiab lwm yam geometric tolerances ntawm pwm Cheebtsam, muab meej kev ruaj ntseg rau cov pwm tom ntej.
Hnyav-lub luag haujlwm kab rov tav lathes kuj ua lub luag haujlwm hauv kev ua kom tiav thiab kho cov pwm loj. Yog tias qhov hnav hauv cheeb tsam tshwm sim thaum siv pwm, pwm tuaj yeem rov ua dua -clamped rau ntawm lub tshuab dhos, thiab qhov chaw hnav tuaj yeem txiav txim siab los ntawm kev sib piv nrog cov ntaub ntawv tsim qauv siv lub tshuab ntsuas hauv online. Tom qab ntawd, hauv zos precision tig kho tuaj yeem ua tsis tau hloov tag nrho cov pwm, txo cov nqi kho mob. Thaum kho, lub tshuab dhos lub micro- pub muaj nuj nqi ua rau kev tswj kev txiav ntawm qib 0.001mm, ua kom muaj kev hloov pauv ntawm qhov chaw kho thiab thaj chaw ib puag ncig, tsis muaj kev cuam tshuam cov pwm tsim cov nyhuv.
Daim ntawv thov hnyav- lub luag haujlwm kab rov tav lathes hauv kev tsim pwm loj ua txhaum los ntawm cov kev txwv ntawm cov khoom siv ib txwm muaj nyob rau hauv cov nqe lus ntawm kev thauj khoom -cov kabmob muaj peev xwm, precision, thiab txheej txheem. Nws tsis tsuas yog txhim kho cov kev ua tau zoo thiab kev ruaj ntseg zoo ntawm cov pwm loj tab sis kuj nthuav dav qhov tsim pwm tsim, muab kev txhim khu kev lag luam rau cov khoom lag luam loj. Nrog rau kev nce qib ntawm CNC thev naus laus zis, nws daim ntawv thov hauv kev tsim pwm loj yuav dhau los ua ntau dua, tsav kev lag luam pwm mus rau qhov loj dua thiab siab dua.
