Qhov kawg zeb yog ib qho ntawm feem ntau siv milling cutters nyob rau hauv CNC milling, thiab nws cov qauv yog qhia nyob rau hauv daim duab. Muaj cov npoo ntawm lub cylindrical nto thiab lub ntsej muag kawg ntawm qhov kawg zeb. Lub txiav ntug ntawm lub cylindrical nto yog lub ntsiab txiav ntug, thiab cov hniav txiav ntawm lub ntsej muag kawg yog qhov thib ob txiav ntug. Lub ntsiab txiav ntug feem ntau yog cov hniav helical, uas tuaj yeem ua rau kev txiav kom ruaj khov thiab txhim kho qhov tseeb ntawm machining. Txij li tsis muaj kev txiav ntug ntawm qhov nruab nrab ntawm lub ntsej muag kawg ntawm lub ntsej muag zoo tib yam, qhov kawg zeb tsis tuaj yeem noj axially, thiab lub ntsej muag kawg ntawm ntug feem ntau yog siv los ua cov txheej txheem hauv qab dav hlau perpendicular mus rau sab.
Txhawm rau txhim kho lub nti curling qhov teeb meem, nce qhov chaw nti, thiab tiv thaiv cov chips los ntawm clogging, tus naj npawb ntawm cov hniav cutter yog me me, thiab lub vojvoog ntawm cov nti zawj arc kuj loj. Feem ntau, tus naj npawb ntawm cov hniav ntawm cov hniav ntxhib hniav kawg yog Z=3 rau 4, tus naj npawb ntawm cov hniav ntawm cov hniav zoo kawg yog Z=5 rau 8, lub tes tsho qauv yog Z{ {6}} mus rau 20, thiab lub vojvoog arc ntawm lub tshuab raj nplaim yog r=2 txog 5mm. Thaum txoj kab uas hla ntawm qhov kawg zeb loj, nws kuj tuaj yeem ua rau cov qauv tsis sib xws los txhim kho cov nyhuv tiv thaiv kev vibration thiab ua rau cov txheej txheem txiav kom ruaj khov.
Lub kaum sab xis ntawm cov qauv kawg mills yog 40 degree txog 45 degree (cov hniav ntxhib) thiab 30 degree txog 35 degree (zoo hniav), thiab lub tes tsho hom kawg mills yog 15 degree txog 25 degree.
End mills nrog me me diameters feem ntau yog ua nyob rau hauv daim ntawv ntawm ib tug shank. Qhov kawg mills ntawm φ2-φ71mm yog ncaj shank; qhov kawg mills ntawm φ6-φ63mm yog Morse thawb shank; qhov kawg mills ntawm φ25-80mm yog 7:24 taper shank nrog cov ntsia hlau qhov, thiab cov ntsia hlau qhov yog siv los zawm cov cuab yeej . Xaus mills nrog txoj kab uas hla ntawm φ40-φ160mm tuaj yeem ua rau hauv lub tes tsho qauv.
