Nto milling cutter ceev thiab pub tus nqi

Basic kev paub ntawm nto milling

Lub ntsej muag milling yog dab tsi? Xav txog milling nrog ib sab ntawm ib qho kawg zeb. Nws lub ntsiab lus dav dav yog "peripheral milling". Tam sim no, yuav ua li cas yog tias peb txiav tawm hauv qab?

Kev hais lus, qhov no yog lub ntsej muag milling, txawm hais tias peb feem ntau tsuas yog xa mus rau nws li lub ntsej muag milling thaum siv tshwj xeeb milling cutters hu ua "lub ntsej muag mills" lossis "lub tes tsho mills". Thov nco ntsoov tias tsis muaj qhov sib txawv ntawm lub ntsej muag milling cutters thiab lub tes tsho milling cutters.

Koj kuj tuaj yeem hnov ​​​​tias 'lub ntsej muag milling' yog hu ua ' nto milling '.

Cia peb xub xaiv hom milling cutter uas zoo tshaj plaws rau koj cov kev xav tau milling. Qhov sib txawv loj tshaj ntawm lub ntsej muag milling cutters yog:

Cov cuab yeej txoj kab uas hla: Lub ntsej muag milling cutters tuaj nyob rau hauv ob qhov ntau thiab tsawg: cov cuab yeej loj thiab cov cuab yeej me me. Txiav txim siab lub cuab tam txoj kab uas hla los xyuas kom meej tias qhov kev txiav ceev (piv tus nqi), spindle ceev, thiab txiav horsepower yuav tsum nyob rau hauv lub peev xwm ntawm koj lub tshuab. Yog tias qhov siab tshaj plaws txiav txoj kab uas hla ntawm lub cuab yeej yog ntau dua qhov chaw koj tab tom ntsib, koj yuav ua tiav qhov zoo tshaj plaws smoothness. Txawm li cas los xij, milling cutters loj dua yuav tsum muaj zog spindles thiab tsis yog ib txwm haum rau qhov chaw nqaim.

Tus naj npawb ntawm cov hniav: Qhov ntau cov hniav muaj, qhov txiav ntau dua muaj, thiab qhov ceev ceev ntawm lub ntsej muag milling cutter. Kev txiav nrawm dua txhais tau tias kev ua haujlwm tuaj yeem ua tiav sai dua. Lub ntsej muag milling cutter nrog ib rab riam tsuas yog hu ua flying cutter. Tab sis sai dua tsis yog ib txwm zoo dua. Tshwj tsis yog tias koj tuaj yeem kho tus kheej qhov siab ntawm tag nrho cov hniav, koj qhov kev txiav ntug milling cutter yuav tsis ua tiav ib qho tiav zoo li ib rab riam ya ya. Feem ntau hais lus, qhov loj ntawm txoj kab uas hla ntawm lub cuab yeej, cov hniav yuav muaj ntau dua.

Geometric duab: Qhov no yog nyob ntawm qhov zoo ntawm cov hniav thiab txoj kev nws yog tsau nyob rau hauv lub ntsej muag milling cutter.

Cia peb saib ze dua ntawm qhov teeb meem geometric no.

Xaiv lub ntsej muag zoo tshaj plaws milling cutter: 45 degrees lossis 90 degrees?

Ua ntej, peb tham txog dab tsi thaum peb hais 45 degrees lossis 90 degrees? Los ntawm kev sib piv ntawm cov duab ntawm ob milling cutters saum toj no, cov lus teb yog heev meej. Nws yog los xyuas lub kaum sab xis ntawm qhov txiav ntawm cov hniav.

Lub kaum sab xis no yog lub kaum sab xis ntawm kev txiav ntug, nrog rau sab laug ntawm 45 degrees thiab cov cuab yeej sab xis ntawm 90 degrees. Lub kaum sab xis no tseem hu ua lub kaum sab xis ntawm lub cuab yeej.

Cov hauv qab no yog qhov kev ua haujlwm zoo tshaj plaws rau ntau lub plhaub milling cutter geometries:

Los ntawm txoj kev, ncig hniav milling cutters kuj hu ua "khawm milling cutters".

Yog li leej twg tuaj yeem muab cov txiaj ntsig zoo rau saum npoo milling machining?

Tau kawg, nws yuav zoo heev yog tias koj tuaj yeem them taus kom muaj ob qho tib si 45℃thiab 90℃milling cutters tib lub sijhawm, tab sis qhov zoo thiab qhov tsis zoo ntawm ob lub tshuab milling no yog dab tsi?

Qhov zoo thiab qhov tsis zoo ntawm 45℃milling cutters

qhov zoo:

Sandvik thiab Kennametal tau hais tias 45℃milling cutter yog qhov kev xaiv zoo dua rau lub ntsej muag milling. Cov laj thawj muab los ntawm ob lub tuam txhab no rau kev xaiv xaiv 45 yog:

· Lub zog txiav yog qhov sib npaug zoo dua, yog li lub zog axial thiab radial quab yuam yog sib xws. Txo cov radial quab yuam kom nws sib npaug nrog lub axial quab yuam tuaj yeem tsis tsuas yog txhim kho qhov smoothness, tab sis kuj tseem muaj txiaj ntsig zoo rau cov ntxaiv bearings.

· Qhov kev ua tau zoo ntawm kev nkag thiab tawm yog qhov zoo dua - qhov cuam tshuam me dua, thiab qhov sib txawv ntawm kev tawg yog me dua.

· A 45℃txiav ntug yog tsim rau kev txiav nrog siab.

· Zoo dua nto tiav -45 muaj qhov ua tiav zoo dua. Kev vibration qis, sib npaug zog, thiab zoo dua inlet geometry yog peb qhov laj thawj.

· Cov chip thinning nyhuv plays lub luag hauj lwm thiab ua rau cov khoom noj ntau dua. Kev txiav nrawm dua txhais tau tias cov khoom tshem tawm ntau dua thiab ua tiav kev ua tiav sai.

45℃milling cutters kuj muaj qee qhov tsis zoo:

· Qhov siab tshaj plaws txiav qhov tob tau raug txo vim yog lub kaum sab xis txhuas.

· Ib txoj kab uas hla loj dua yuav ua rau muaj teeb meem tshem tawm.

· 90℃lub kaum sab xis milling lossis square xub pwg milling tsis raug tso cai

· Tej zaum yuav ua rau tawg lossis burrs ntawm sab tawm ntawm lub cuab yeej thaum tig.

· Lub lateral (axial) quab yuam thov ntawm 90 degrees yog me me, txog ib nrab. Qhov no muaj qhov zoo ntawm cov phab ntsa nyias, vim tias kev xa cov quab yuam ntau dhau mus rau phab ntsa tuaj yeem ua rau cov khoom vibration thiab lwm yam teeb meem. Thaum nws nyuaj los yog tsis yooj yim sua kom txhim kho qhov chaw hauv lub fixture, qhov no kuj yog qhov zoo dua.

Txhawm rau kom tsis txhob hnov ​​​​qab txog lub ntsej muag mills, lawv muab qee qhov zoo ntawm txhua hom ntsej muag zeb, thiab lawv kuj yog qhov muaj zog tshaj plaws. Yog li ntawd, yog tias koj yuav tsum tau nrog cov khoom siv tshuab nyuaj, milling tej zaum yuav yog qhov kev xaiv zoo tshaj plaws.

Yog tias koj tab tom nrhiav cov txiaj ntsig zoo tshaj plaws, ces koj yuav xav tau rab riam ya. Feem ntau, cov riam ya tuaj yeem muab cov nyhuv zoo tshaj plaws. Los ntawm txoj kev, koj tsuas yog xav tau ib qho kev txiav kom yooj yim hloov txhua lub ntsej muag milling cutter rau hauv lub tshuab txiav kom zoo.
