Hav nyob ntawd! Raws li tus neeg muag khoom ntawm Graphite Pom Hniav, Kuv feem ntau tau nug txog kev txiav ceev ntawm cov hniav no. Nws yog ib lub ntsiab lus tseem ceeb heev, tshwj xeeb tshaj yog tias koj nyob hauv kev ua lag luam rau cov hniav uas tuaj yeem ua tiav txoj haujlwm sai thiab ua tau zoo. Yog li, cia peb dhia mus rau hauv thiab tshawb xyuas qhov kev txiav ceev ntawm graphite saw hniav yog dab tsi.
Txiav ceev yog dab tsi?
Ua ntej yam ua ntej, peb yuav tsum nkag siab tias kev txiav ceev txhais tau li cas. Hauv cov ntsiab lus yooj yim, kev txiav ceev yog hais txog ceev npaum li cas ntawm ntug ntawm cov saw hniav txav dhau ntawm cov khoom nws txiav. Nws yog feem ntau ntsuas nyob rau hauv qhov chaw taw ib feeb (SFM) nyob rau hauv lub imperial system los yog meters ib feeb (m / min) nyob rau hauv lub metric system.
Kev txiav ceev yog qhov tseem ceeb heev vim tias nws cuam tshuam ncaj qha rau cov saw hniav ua tau zoo npaum li cas. Yog tias qhov txiav nrawm dhau qeeb, cov hniav yuav tsis txiav los ntawm cov graphite zoo, ua rau kev txiav ntxhib thiab ua rau cov hniav puas. Ntawm qhov tod tes, yog tias qhov txiav nrawm nrawm dhau, nws tuaj yeem ua rau muaj cua sov ntau dhau, uas tuaj yeem ua rau cov hniav puas thiab txo nws txoj sia.
Cov yam ntxwv cuam tshuam rau kev txiav ceev ntawm Graphite Pom Hniav
Muaj ntau ntau yam uas tuaj yeem cuam tshuam qhov kev txiav ceev ntawm graphite saw hniav. Cia peb saib qee qhov tseem ceeb tshaj plaws:
Hniav Khoom
Cov khoom ntawm cov saw hniav ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws txoj kev txiav ceev. Graphite saw hniav feem ntau yog ua los ntawm siab - ceev steel (HSS), carbide, los yog pob zeb diamond - cov ntaub ntawv tipped.
Pob zeb diamond - tipped saw hniav paub txog lawv qhov tshwj xeeb txiav ceev thiab kav ntev. Pob zeb diamond yog ib qho ntawm cov ntaub ntawv nyuaj tshaj plaws nyob rau hauv lub ntiaj teb, thiab nws tuaj yeem txiav tau yooj yim los ntawm graphite nrog kev ua haujlwm tsawg. Yog tias koj tab tom nrhiav rau cov hniav uas tuaj yeem txiav graphite sai thiab huv si, Pob Zeb Diamond Cov Cuab Yeej yog qhov kev xaiv zoo.
Carbide hniav kuj nrov rau txiav graphite. Lawv muab qhov sib npaug zoo ntawm kev txiav ceev thiab tus nqi. Carbide nyuaj dua siab - ceev steel, uas tso cai rau nws txiav los ntawm graphite ntawm ib tug kuj ceev pace.
Siab - ceev steel hniav yog pheej yig dua tab sis feem ntau muaj qis txiav ceev piv rau carbide thiab pob zeb diamond - tipped hniav. Lawv haum rau lub teeb - lub luag haujlwm txiav daim ntawv thov qhov twg ceev tsis yog thawj qhov kev txhawj xeeb.
Hniav Dia
Txoj kab uas hla ntawm cov saw hniav kuj cuam tshuam rau kev txiav ceev. Ib txoj kab uas hla loj dua yuav muaj qhov txiav nrawm dua ntawm ntug sab nraud piv rau cov hniav me me, piv txwv li qhov sib hloov ceev. Txawm li cas los xij, cov hniav loj dua tuaj yeem xav tau lub zog ntau dua los ua haujlwm thiab tuaj yeem ua tau ntau dua los tuav.
Rotational ceev ntawm lub saw
Kev sib hloov ceev ntawm cov saw yog lwm qhov tseem ceeb. Lub saw rotates sai dua, qhov siab dua qhov txiav ceev. Tab sis koj yuav tsum xyuas kom meej tias qhov kev sib hloov ceev yog nyob rau hauv qhov kev pom zoo rau qhov tshwj xeeb pom hniav. Khiav lub saw ntawm kev sib hloov ceev heev tuaj yeem ua rau cov hniav tuaj yeem ua kom sov thiab tawg.
Graphite Material Properties
Cov khoom ntawm graphite raug txiav, xws li nws hardness, ntom, thiab grain qauv, tuaj yeem cuam tshuam qhov txiav ceev. Harder and denser graphite materials will require a lower cutting speed to avoid damaging the blade. Piv txwv li, nplua - grained graphite yuav raug txiav ntawm qhov nrawm dua piv rau ntxhib - grained graphite.
Pom zoo txiav ceev rau graphite saw hniav
Txawm hais tias qhov tseeb txiav ceev yuav nyob ntawm seb yam uas tau hais los saum no, ntawm no yog qee cov lus qhia dav dav:
Pob zeb diamond - cov hniav: Rau feem ntau graphite tej daim ntawv thov, txiav ceev ntawm 1000 - 3000 nto taw ib feeb (SFM) los yog 300 - 900 meters ib feeb (m/min) yog pom zoo. Cov hniav no tuaj yeem ua haujlwm siab - ceev txiav yam tsis muaj kev hnav thiab tsim kua muag ntau.
Carbide hniav: Kev txiav ceev ntawm 500 - 1500 SFM lossis 150 - 450 m/min feem ntau yog tsim nyog. Carbide hniav tuaj yeem txiav graphite ntawm qhov nrawm nrawm thaum tuav cov hniav zoo.
Siab - ceev steel hniav: Rau HSS hniav, txiav ceev ntawm 200 - 500 SFM lossis 60 - 150 m / min yog qhov pib zoo. Txij li HSS cov hniav tsis muaj cua sov tsawg dua - tiv taus, kev txiav qis qis yog tsim nyog los tiv thaiv overheating.
Nws tseem ceeb heev uas yuav tsum nco ntsoov tias cov no tsuas yog cov lus pom zoo. Tej zaum koj yuav tau kho qhov txiav ceev raws li koj cov kev txiav tshwj xeeb thiab cov cuab yeej koj siv.
Cov txiaj ntsig ntawm Optimizing txiav ceev
Optimizing lub txiav ceev ntawm koj graphite saw hniav tuaj yeem nqa tau ntau yam txiaj ntsig:
Txhim kho kev txiav zoo
Thaum txiav ceev yog teem kom raug, koj yuav tau txais ib tug smoother thiab huv si txiav. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog tias koj tab tom ua haujlwm rau cov haujlwm uas yuav tsum tau muaj qhov siab, xws li ua Graphite Thermal Sheet lossis Graphite Gasket.
Ntev Hniav Lub Neej
Los ntawm kev siv qhov tsim nyog txiav ceev, koj tuaj yeem txo qhov hnav thiab tsim kua muag ntawm cov hniav. Qhov no txhais tau hais tias cov hniav yuav kav ntev dua, txuag koj cov nyiaj ntawm kev hloov cov nqi hauv lub sijhawm ntev.
Kev tsim khoom siab dua
Ib qhov zoo - optimized txiav ceev tso cai rau koj ua kom tiav koj cov hauj lwm txiav sai dua, ua rau koj cov khoom tsim tau tag nrho. Koj tuaj yeem tau txais kev ua haujlwm ntau dua hauv lub sijhawm tsawg, uas yog ib txwm ntxiv rau kev lag luam.
