5 Lub tswv yim rau xaiv qhov zoo tshaj plaws spindle range

Kawm paub xaiv qhov zoo spindle ntau npaum li cas thiab xyuas kom meej tias kojCNC machining chawlos yog tig chaw khiav ib lub voj voog optimized.#cnctechtalk

Seb koj puas siv aCNC milling tshuabnrog ib tug spindle rotating cuab tam los yog aCNC tshuab dhosnrog spindle rotating workpiece, loj CNC tshuab cuab yeej muaj ntau yam spindle.Qhov qis spindle ntau muab lub zog ntau dua, thaum qhov ntau dua muab kev ceev dua.Nws yog ib qho tseem ceeb los xyuas kom meej tias lub machining ua tiav nyob rau hauv qhov zoo spindle ceev ntau yam kom ua tau zoo tshaj plaws productivity.Nov yog tsib lub tswv yim rau xaiv qhov zoo:
Lub tshuab cuab yeej tuam txhab luam tawm cov yam ntxwv ntawm spindle nyob rau hauv lawv cov kev khiav hauj lwm phau ntawv.Nyob ntawd koj yuav pom qhov tsawg kawg nkaus thiab siab tshaj plaws rpm rau txhua qhov, nrog rau lub zog xav tau hauv tag nrho rpm ntau.
Yog tias koj tsis tau kawm cov ntaub ntawv tseem ceeb no, koj lub sijhawm mus ncig yuav tsis zoo.Ua kom qhov teeb meem loj dua, koj tuaj yeem tso siab ntau dhau ntawm lub tshuab spindle ntawm lub tshuab, lossis txawm tias nws nres.Kev nyeem phau ntawv thiab nkag siab txog cov yam ntxwv ntawm spindle tuaj yeem pab koj txhim kho cov khoom tsim tau ntawm koj lub tshuab.
Muaj tsawg kawg yog ob txoj kev hloov pauv hloov pauv: ib qho yog lub kaw lus nrog ntau lub tshuab spindle tsav lub cev muaj zog, thiab lwm qhov yog lub kaw lus nrog lub tshuab tsav.
Cov qub hloov qhov ntau ntawm hluav taws xob los ntawm kev hloov lub cev muaj zog windings lawv siv.Cov kev hloov no yuav luag instantaneous.
Lub kaw lus nrog lub tshuab xa hluav taws xob feem ntau tsav ncaj qha rau hauv nws qhov siab tshaj plaws thiab koom nrog kev sib kis hauv qhov qis dua.Qhov kev hloov pauv yuav siv sijhawm li ob peb vib nas this, tshwj xeeb tshaj yog thaum lub spindle yuav tsum nres thaum lub sijhawm ua haujlwm.
Rau CNC, qhov kev hloov ntawm spindle ntau yog pob tshab me ntsis, vim hais tias cov spindle ceev tau teev nyob rau hauv rpm, thiab S lo lus ntawm qhov ceev ceev kuj yuav ua rau lub tshuab xaiv qhov cuam tshuam spindle ntau yam.Xav tias qhov qis-ceev ntau ntawm lub tshuab yog 20-1,500 rpm, thiab qhov siab ceev yog 1,501-4,000 rpm.Yog tias koj qhia S lo lus ntawm S300, lub tshuab yuav xaiv qhov qis qis.S lo lus ntawm S2000 yuav ua rau lub tshuab xaiv qhov siab.
Ua ntej, qhov kev zov me nyuam yuav ua rau tsis tsim nyog hloov pauv ntawm cov peev txheej ntawm cov cuab yeej.Rau cov neeg kho tshuab kis tau tus mob, qhov no yuav ua rau kom lub sij hawm voj voog, tab sis nws yuav raug saib tsis taus vim nws tsuas yog tshwm sim thaum qee cov cuab yeej siv sij hawm ntev los hloov dua lwm tus.Khiav cov cuab yeej uas yuav tsum tau muaj qhov sib npaug ntawm qhov sib lawv liag yuav txo lub sijhawm voj voog.
Thib ob, spindle ceev rpm xam rau kev ua haujlwm roughing muaj zog tuaj yeem tso cov ntxaiv ntawm qhov qis kawg ntawm qhov siab spindle ntau yam, qhov twg lub zog yog txwv.Qhov no yuav ua rau lub zog ntau dhau ntawm lub tshuab spindle tsav lossis ua rau lub tshuab spindle nres.Ib tug paub zoo programmer yuav txo tau me ntsis spindle ceev thiab xaiv lub siab tshaj plaws ceev nyob rau hauv qis ntau yam, qhov twg muaj txaus lub hwj chim los ua lub machining lag luam.
Rau qhov chaw tig, qhov kev hloov ntawm spindle ntau yam yog ua los ntawm M code, thiab qhov siab dua feem ntau overlaps nrog qhov qis dua.Rau qhov chaw tig nrog peb-spindle ntau yam, cov iav qis yuav sib haum rau M41 thiab qhov ceev yog 30-1,400 rpm, nruab nrab iav tuaj yeem sib haum rau M42, thiab qhov ceev yog 40-2,800 rpm, thiab cov iav siab yuav sib haum. rau M43 thiab qhov ceev yog 45-4,500 rpm.
Qhov no tsuas yog siv rau kev xa cov chaw thiab cov haujlwm uas siv qhov nrawm nrawm.Thaum qhov nrawm nrawm tas li, CNC yuav txuas ntxiv xaiv qhov ceev (rpm) raws li qhov teev saum npoo ceev (ko taw lossis m / min) thiab txoj kab uas hla tam sim no tau ua tiav.
Thaum koj teem lub feedrate ib kiv puag ncig, lub spindle ceev yog inversely proportional rau lub sij hawm.Yog tias koj tuaj yeem ua ob npaug ntawm qhov nrawm nrawm, lub sijhawm xav tau rau kev ua haujlwm machining yuav raug txiav ib nrab.
Ib txoj cai nrov ntawm tus ntiv tes xoo rau kev xaiv spindle ntau yam yog roughing nyob rau hauv qhov qis qis thiab ua tiav hauv qhov siab.Txawm hais tias qhov no yog txoj cai zoo ntawm tus ntiv tes xoo los xyuas kom meej tias lub spindle muaj lub zog txaus, nws tsis ua haujlwm zoo thaum xav txog kev ceev.
Xav txog 1-inch inch workpiece uas yuav tsum tau muab roughly tig thiab zoo tig.Qhov pom zoo ceev ntawm cov cuab yeej roughing yog 500 sfm.Txawm nyob rau ntawm qhov siab tshaj plaws txoj kab uas hla (1 nti), nws yuav tsim 1,910 rpm (3.82 npaug ntawm 500 faib los ntawm 1).Ib txoj kab uas hla me me yuav xav tau kev nrawm dua.Yog tias tus programmer xaiv qhov qis qis raws li kev paub dhau los, lub spindle yuav ncav cuag qhov txwv ntawm 1,400 rpm.Piv txwv tias muaj zog txaus, kev ua haujlwm roughing yuav ua kom tiav sai dua nyob rau hauv ntau dua.
Qhov no kuj tseem siv tau rau cov chaw tig thiab cov haujlwm roughing uas yuav tsum tau ua kom nrawm nrawm.Xav txog qhov ntxhib tig ib txoj kab uas hla 4-nti nrog ntau txoj kab uas hla, qhov tsawg tshaj plaws yog 1 nti.Xav tias qhov kev pom zoo ceev yog 800 sfm.Ntawm 4 ntiv tes, qhov xav tau ceev yog 764 rpm.Qhov qis qis yuav muab lub zog xav tau.
Raws li qhov roughing txuas ntxiv, txoj kab uas hla yuav me dua thiab qhov nrawm nce ntxiv.Ntawm 2.125 ntiv tes, qhov zoo tshaj plaws machining yuav tsum tau ntau tshaj 1,400 rpm, tab sis cov ntxaiv yuav nce siab nyob rau hauv qhov qis ntawm 1,400 rpm, thiab txhua txoj kev nruam nruam yuav siv sij hawm ntev dua li qhov yuav tsum tau ua.Nws yuav zoo dua los hloov mus rau qhov nruab nrab ntawm lub sijhawm no, tshwj xeeb tshaj yog tias qhov hloov pauv sai sai.
Thaum qhov kev zov me nyuam nkag mus rau hauv lub tshuab, txhua lub sijhawm tau txais kev cawmdim los ntawm kev hla qhov kev npaj ua haujlwm tau yooj yim ploj.Thov ua raws li cov kauj ruam hauv qab no kom ntseeg tau tias muaj kev vam meej.
Cov kev txwv tsis pub qhia CNC txhua qhov kev nthuav dav ntawm cov cuab yeej tshwj xeeb uas tau siv thiab siv tag nrho CNC nta thiab kev ua haujlwm li cas.
