Dry-Txiav rau Hlau yog dab tsi?

Nkag siab Circular Hlau Saws

Raws li lub npe implies, ib ncig hlau saw siv disk-puab hniav los txiav cov ntaub ntawv. Hom saw no yog qhov zoo tagnrho rau kev txiav hlau vim tias nws cov qauv tsim tso cai rau nws kom xa cov kev txiav tawm mus tas li. Tsis tas li ntawd, lub voj voog ncig ntawm cov hniav tsim ib qho kev txiav tawm tas mus li, ua rau nws txiav los ntawm cov hlau tsis muaj ferrous thiab cov hlau tsis muaj hlau.Dry-cutting yog ib txoj kev txiav los ntawm cov hlau tsis siv cov kua coolant. Es tsis txhob siv cov kua los txo cov cua sov thiab kev sib txhuam, qhuav-txiav cia siab rau cov hniav uas yog tsim tawm los yog npog rau hauv, cov khoom uas muaj peev xwm tiv taus cua sov thiab txhuam cov hlau tsim. Feem ntau, pob zeb diamond hniav yog siv rau qhuav txiav vim lawv hardness thiab durability.

Lub voj voog saws siv rau qee cov hlau sawing yuav ua kom muaj cua sov ntau thaum txiav cov hlau, txhuas thiab lwm yam khoom tshwj xeeb; tab sis qee zaum nws yog ib qho tsim nyog yuav tsum khaws cov sawed workpiece thiab saw hniav txias. Nyob rau hauv cov ntaub ntawv no, ib tug tshwj xeeb Lub voj voog saw hniav ntawm cov khoom siv hniav ua tiav cov sawing, uas yog ib tug txias saw.

Qhov zais cia rau qhov txias txias lub peev xwm ua kom cov khoom ua haujlwm thiab pom cov hniav txias yog lub taub hau tshwj xeeb: lub taub hau cermet.

Cermet cutter hau tuav cov yam ntxwv ntawm ceramics xws li siab hardness, siab zog, hnav tsis kam, kub tsis kam, oxidation kuj thiab tshuaj stability, thiab muaj zoo hlau toughness thiab plasticity. Cermet muaj qhov zoo ntawm ob qho tib si hlau thiab ceramic. Nws muaj tsawg ntom, siab hardness, hnav tsis kam thiab zoo thermal conductivity. Nws yuav tsis nkig vim txias txias lossis cua sov. Thaum lub sij hawm txiav, cov serrations ntawm lub taub hau ceramic cutter yuav ua kom sov rau cov chips, yog li ua kom cov saw hniav thiab txiav cov khoom txias.

Txias Sawing Qhov Zoo

Cov saws txias tuaj yeem siv rau kev txiav ntau yam sib txawv, nrog rau cov pas nrig, cov raj, thiab extrusion. Automated, nyob rau hauv lub voj voog txias saws ua haujlwm zoo rau kev tsim khoom thiab rov ua haujlwm dua qhov kev ua siab ntev thiab ua tiav yog qhov tseem ceeb. Cov tshuab no muaj qhov sib txawv ntawm cov hniav nrawm thiab hloov tau tus nqi pub rau cov khoom siv ceev ceev thiab tsis muaj burr-free, raug txiav.Cold saws muaj peev xwm ntawm machining feem ntau ferrous thiab non-ferrous alloys. Cov txiaj ntsig ntxiv muaj xws li kev tsim cov burr tsawg, tsawg dua, tsis muaj xim tsis zoo thiab tsis muaj plua plav.

Cov txheej txheem txias txias muaj peev xwm ua tau siab dhau ntawm cov hlau loj thiab hnyav dua - hauv qee qhov xwm txheej, txawm tias nruj li ± 0.005 "(0.127 hli) kam rau ua. Cov saws txias tuaj yeem siv rau kev txiav tawm ntawm ob qho tib si ferrous thiab non-ferrous hlau, thiab rau ob qho tib si ncaj thiab angled txiav. Piv txwv li, ntau qib ntawm cov hlau qiv lawv tus kheej rau qhov txias txias, thiab tuaj yeem txiav sai sai yam tsis muaj cua sov thiab kev sib txhuam.

Qee qhov Downsides rau Cold Saws

Txawm li cas los xij, qhov txias txias tsis zoo rau qhov ntev hauv qab 0.125 "(3.175 hli). Tsis tas li ntawd, txoj kev tuaj yeem ua rau hnyav burrs. Tshwj xeeb, nws yog ib qho teeb meem uas koj muaj ODs qis dua 0.125 "(3.175 mm) thiab ntawm cov ID me me, qhov twg lub raj yuav raug kaw los ntawm burr uas tsim los ntawm cov khaub thuas pom.

Lwm qhov tsis zoo rau cov saws txias yog qhov nyuaj ua rau cov sawb nkig thiab raug kev poob siab. Txhua qhov kev vibration - piv txwv li, los ntawm qhov tsis txaus clamping ntawm ib feem lossis tus nqi pub mis tsis raug - tuaj yeem ua rau cov hniav puas tau yooj yim. Tsis tas li ntawd, cov saws txias feem ntau ua rau qhov poob tseem ceeb ntawm kerf, uas txhais tau tias ploj lawm thiab cov nqi ntau dua.
Thaum txias sawing tuaj yeem siv los txiav feem ntau cov ferrous thiab non-ferrous alloys, nws tsis pom zoo rau cov hlau tawv heev - tshwj xeeb, cov tawv tawv dua qhov pom nws tus kheej. Thiab thaum cov saws txias tuaj yeem ua bundled txiav, nws tsuas yog ua tau nrog txoj kab uas hla me me thiab yuav tsum tau kho tshwj xeeb.

Cov Hniav Hniav Rau Kev Txiav Ceev

Txias sawing siv lub voj voog kom tshem tawm cov khoom siv thaum hloov cov khoom cua sov rau cov chips uas tsim los ntawm cov saw hniav. Lub tshuab txias txias siv cov khoom siv high-speed steel (HSS) lossis tungsten carbide-tipped (TCT) hniav tig ntawm qis RPMs.
Contrary to lub npe, HSS hniav yog tsis tshua muaj siv nyob rau hauv high speeds. Hloov chaw, lawv cov cwj pwm tseem ceeb yog hardness, uas ua rau lawv muaj zog tiv taus cua sov thiab hnav. TCT cov hniav yog kim dua tab sis kuj nyuaj heev thiab muaj peev xwm ua haujlwm ntawm qhov kub siab tshaj HSS. Qhov no tso cai rau TCT pom cov hniav tuaj yeem ua haujlwm ntawm tus nqi nrawm dua li HSS cov hniav, txo qis lub sijhawm txiav.

Txiav sai sai yam tsis muaj kev kub ntxhov thiab kev sib txhuam, txias sawing tshuab tuaj yeem tiv taus hnav ntxov ntxov uas tuaj yeem cuam tshuam rau qhov kawg ntawm qhov txiav. Tsis tas li ntawd, ob hom hniav tuaj yeem rov ua dua thiab siv tau ntau zaus ua ntej muab pov tseg. Lub neej ntev hniav no pab ua kom txias sawing ib txoj kev siv nyiaj rau kev txiav ceev ceev thiab ua tiav zoo.

Feem ntau yuam kev kom tsis txhob Thaum qhuav-txiav hlau

Raws li koj siv cov hniav uas nyuaj dua li cov hlau, kev txiav qhuav tuaj yeem nyuaj rau koj cov cuab yeej. Txhawm rau kom tsis txhob muaj kev puas tsuaj lossis kev sib tsoo thaum txiav hlau, ntawm no yog qee qhov yuam kev uas yuav tsum tau saib rau:

Tsis yog Hniav Ceev: Thaum koj qhuav-txiav los ntawm hlau, nws yog ib qho tseem ceeb uas yuav tau xyuam xim rau qhov ceev ntawm cov hniav. Yog tias koj cov hniav mus nrawm dhau, nws tuaj yeem ua rau cov hlau khoov lossis flex thiab tawg koj cov hniav. Ntawm qhov tod tes, yog tias nws txav mus qeeb dhau, cua sov yuav tsim nyob rau hauv koj cov saw thiab ua rau nws puas tsuaj.

Clamping tsis raug: Xyuas kom koj ruaj ntseg clamp cia txhua yam khoom hlau koj txiav. Cov khoom txav mus los yog qhov txaus ntshai thiab tuaj yeem ua rau muaj kev phom sij loj.

Thaum siv lub tshuab txias txias, nws yog ib qho tseem ceeb uas yuav tau xaiv cov hniav kom zoo rau cov khoom raug txiav.

Xaiv cov hniav zoo tshaj plaws rau koj lub qhov txias txias yuav nyob ntawm:

* Lub hardness ntawm cov khoom

* Qhov loj ntawm ntu

* Phab ntsa thickness

Cov khoom seem yuav tsum tau cov hniav nrog cov hniav ntxhib, thaum cov phab ntsa nyias nyias lossis cov duab nrog cov ntu me me yuav tsum tau cov hniav nrog lub suab zoo dua. Yog tias koj muaj cov hniav ntau dhau ntawm cov khoom nyob rau hauv ib lub sij hawm, qhov tshwm sim yuav tearing es tsis txhob nti tawm. Qhov no ua rau muaj kev nce siab hauv shearing stress.

Ntawm qhov tod tes, thaum txiav cov phab ntsa hnyav lossis cov khib nyiab uas siv cov hniav zoo heev, cov chips yuav muab kauv rau hauv lub gullet. Txij li cov hniav zoo nkauj muaj cov gullets me me, cov chips sib xyaw yuav dhau lub peev xwm ntawm cov gullets thiab nias rau ntawm phab ntsa ntawm cov workpieces uas ua rau cov chips jamming thiab tau daig. Cov hniav txias yuav pib ua zoo li nws tsis yog txiav, tab sis qhov ntawd yog vim nws tsis tuaj yeem tom nrog jammed gullets. Yog tias koj yuam cov hniav los ntawm, koj yuav ntsib kev txiav tsis zoo thiab kev ntxhov siab ntau dua, uas thaum kawg tuaj yeem ua rau koj cov hniav txias tawg.

Thov nco ntsoov tias thaum xaiv cov hniav kom zoo rau koj daim ntawv thov yog qhov tseem ceeb heev, nws tsis yog qhov tsuas yog txiav txim siab qhov zoo tshaj plaws txias saw hniav rau koj daim ntawv thov. Zoo ib yam li lwm cov cuab yeej, qhov txias pom qhov ua tau zoo thiab kev ua haujlwm ntev yog nyob ntawm qhov zoo ntawm qhov tseem ceeb. cov khoom xws li cov hniav. HERO muag qhov zoo tshaj plaws txias pom hniav vim peb siv cov kws tshaj lij German ua tshuab los tsim peb cov khoom. Peb cov hniav yuav pab koj txiav hlau rau suav tsis txheeb cov haujlwm.Peb zoo siab los pab hauv xov tooj!
