Lub ntsiab txiav ntug ntawm qhov kawg zeb yog nyob rau ntawm lub cylindrical nto, thiab txiav ntug ntawm lub ntsej muag kawg yog qhov thib ob txiav ntug. Thaum ua haujlwm, qhov kev txav tsis tuaj yeem ua raws li axial kev taw qhia ntawm milling cutter. End mills tuaj yeem siv rau hauv machining teb xws li sab machining, zawj machining, thiab nkhaus nto machining. Kuj tseem muaj ntau yam kawg mills uas tuaj yeem siv rau ntau hom machining.
Yav dhau los, high-speed steel integral kawg mills tau nquag siv, tab sis tam sim no nrog kev nce qib ntawm cov txheej txheem txheej txheem thiab cov cuab yeej siv tshuab, coated carbide khoom kawg mills thiab indexable kawg mills tau maj mam nrov thiab siv dav hauv kev ua pwm, cov khoom siv hardness siab. kev ua thiab lwm yam.
1. Lub npe ntawm txhua feem ntawm qhov kawg zeb:
Helix lub kaum sab xis: Qhov loj dua lub kaum sab xis ntawm lub qhov kawg zeb, qhov ntev ntawm txoj kab sib txuas ntawm lub workpiece thiab txiav ntug, qhov me me ntawm cov khoom siv rau kev txiav ntug ntawm ib chav tsev ntev, uas yog qhov zoo rau kev siv lub neej ntev. Tab sis ntawm qhov tod tes, raws li lub kaum sab xis helix nce, axial tivthaiv quab yuam ntawm kev txiav kuj nce, ua rau lub cuab yeej yooj yim poob ntawm tus kov. Yog li ntawd, thaum machining nrog lub cuab yeej nrog lub kaum sab xis loj, lub rigidity ntawm lub cuab yeej yog yuav tsum tau. Lub 0 degree helix lub kaum sab xis yog hu ua ntug ncaj, thiab nws txoj kab sib txuas yog qhov luv tshaj plaws.
Xaiv lub kaum sab xis helix: Stainless hlau yog ib qho nyuaj-rau-txiav cov khoom uas tsis tshua muaj thermal conductivity, uas muaj kev cuam tshuam zoo rau cov cuab yeej taub. Kev siv lub tshuab kawg nrog lub kaum sab xis loj yog qhov zoo rau kev ua kom lub neej ntev. Raws li lub hardness nce, txiav kuj ntawm high-hardness cov ntaub ntawv nce, ces kawg mills nrog loj helix ces kaum yuav tsum tau xaiv. Rau kev ua cov phaj nyias thiab lwm yam xwm txheej uas qhov rigidity ntawm lub workpiece yog tsawg, ib qho kawg zeb nrog lub me me helix lub kaum sab xis yuav tsum tau siv.
Core thickness: Core thickness yog ib qho tseem ceeb hauv kev txiav txim siab rigidity thiab nti flute ntawm ib qho kawg zeb. Cov tub ntxhais tuab ntawm cov khoom kawg mills feem ntau yog 60 feem pua ntawm cov kab sab nraud. Raws li cov tub ntxhais thickness nce, qhov chaw hla ntu nce thiab qhov rigidity nce, tab sis lub hnab tshos nti txo thiab cov nti tshem tawm kev ua haujlwm tsis zoo; ntawm qhov tsis sib xws, cov tub ntxhais thickness txo thiab rigidity txo, tab sis cov nti tshem tawm kev ua tau zoo nce.

2. Tus naj npawb ntawm cov npoo ntawm feem ntau siv kawg mills
3. Hom thiab cov duab ntawm qhov kawg mills
Cov hom thiab cov duab ntawm qhov kawg mills tuaj yeem raug cais raws li peripheral ntug, hauv qab ntug, shank thiab caj dab. Cov hom sib txawv muaj cov duab sib txawv thiab cov yam ntxwv, thiab lawv cov ntawv thov kuj txawv.
1) Hom, cov duab thiab cov yam ntxwv ntawm peripheral hniav
2) Hom, cov duab thiab cov yam ntxwv ntawm cov ntug hauv qab
3) Hom, cov duab thiab cov yam ntxwv ntawm tus kov thiab caj dab
Thaum lub qhov kawg zeb tig, qhov nruab nrab ntawm ntug hauv qab yog qhov ruaj khov, thiab nws tsis muaj cov khoom txiav thiab nti tshem tawm, yog li nws tsis tuaj yeem txiav vertically.
