Khoom carbide kawg mills
Khoom carbide kawg mills yog ib feem tseem ceeb ntawm carbide cutters (lwm yam tseem ceeb yog carbide tuag milling cutters, uas yuav tau tham nyob rau hauv Tshooj 5 ntawm phau ntawv no). Qhov tseem ceeb ntawm cov khoom carbide kawg zeb yog qhia hauv daim duab 3-8. Cov khoom carbide milling cutter feem ntau muab faib ua ob ntu: qhov ua haujlwm thiab lub shank. Tam sim no, feem ntau siv txoj kab uas hla yog 3 ~ 20mm. Milling cutters me dua 3mm lossis loj dua 20mm kuj muaj, tab sis lawv tsis siv dav thiab tsis tau tham hauv phau ntawv no.

Qhov ua haujlwm ntawm cov khoom carbide milling cutter
Qhov kev ua haujlwm ntawm lub tshuab txiav yog kwv yees li ntawm peb ntu ntu ntu: cov hniav kawg, cov hniav ncig, thiab lub taub vojvoog lossis chamfer uas hloov ntawm ob.
Xaus cov hniav
Cov hniav kawg ntawm qhov kawg zeb yog cov seem ntawm cov hniav uas yog perpendicular mus rau lub cuab tam axis ntawm lub taub hau ntawm lub milling cutter. Cov tsis tseem ceeb ntawm cov khoom carbide kawg zeb kawg cov hniav yog qhia hauv daim duab 3-9. Muaj ob lub ntsiab ntawm milling cutter kawg cov hniav, ib hom cutter hniav yog ntev, uas yuav hla lub axis ntawm lub milling cutter, thiab cutter hniav no yog hu ua over-center cutter hniav; Lwm qhov yog cov hniav luv luv uas tsis hla lub cutter axis. Hauv daim duab 3-10, qhov liab loj ntawm daim duab hauv qab no yog cov hniav ntev (dhau ntawm cov hniav hauv nruab nrab), thaum qhov loj me yog cov hniav luv (tab sis cov hniav hauv nruab nrab).

Pem hauv ntej thiab nram qab cov ces kaum
Zoo li txhua yam cuab yeej, carbide kawg mills muaj lub rake thiab lub kaum sab xis. Thaum cov hniav kawg tau muab tso rau hauv milling (tseem hu ua "drilling") ntawm qhov chaw qis qis (saib cov khoom noj zoo hauv daim duab 3-11), cov hniav kawg yog lub ntsiab txiav ntug uas ua haujlwm rau lub ntsiab machining. Kev soj ntsuam raws li qhov taw tes ntse ntawm ib qho ntawm cov npoo txiav (xiav dot hauv daim duab), cov kev taw qhia ntawm kev txiav ceev yog qhia los ntawm lub xub xiav thaum tus nqi pub yog tsis quav ntsej. Lub dav hlau txiav rau qhov taw tes no tau pom tias yog kab liab dot tuab dua hauv daim duab 3-11, thaum lub dav hlau txiav yog cov kab ntsuab tuab dua hauv daim duab. Raws li cov dav hlau no, cov rake thiab nraub qaum ntawm cov hniav kawg tuaj yeem tau txais. Vim tias qhov kawg zeb kawg ntug yuav tsum muaj cov chips ntau dua nyob rau hauv qhov chaw me me, feem ntau yuav tsum tau tshem tawm cov khoom siv ntau dua nyob rau sab nraum qab ntawm cov hniav kawg los tsim lub kaum sab xis thib ob ntawm cov hniav kawg. Lub kaum sab xis thib ob yog cov xim daj tsaus ntawm daim duab 3-10.

Xaus backlash kaum sab xis
Cov hniav kawg ntawm qhov kawg zeb muaj lub kaum ntse ntse tshwj xeeb, uas yog hu ua qhov kawg backlash lub kaum sab xis hauv daim duab 3-11. Lub kaum sab xis no yog qhov tseem ceeb nyob rau hauv lub voj voog sab nraud ntawm ntug kawg ntawm lub cutter tshaj li ntawm paraxial axis, thiab cov hniav ntawm lub ntsej muag kawg ntawm lub cutter tsim ib qho concave "disc", yog li qhov kawg backlash lub kaum sab xis no tseem hu ua tus "disc core angle". Lub backlash lub kaum sab xis ntawm qhov kawg no feem ntau yog li 2 degree.
Daim duab 3-12 yog lub voj voog schematic txog cov nyhuv ntawm lub backlash lub kaum sab xis kawg. Thaum lub milling cutter yog axial pub, qhov kawg ntug siv los ua lub ntsiab txiav ntug, thiab qhov kawg backlash lub kaum sab xis ntxiv rau 90 degree yog nkag mus rau lub kaum sab xis ntawm cov hniav kawg: thiab thaum lub milling cutter yog radially noj, lub ntug circumferential ua tus. lub ntsiab txiav ntug, qhov kawg ntug dhau los ua qhov thib ob txiav ntug, thiab lub backlash lub kaum sab xis ntawm cov hniav ncig yog lub kaum sab xis nkag.

Xaus hniav zawj
Rau qhov kawg mills nrog tshaj-nruab nrab txiav npoo, kuj tseem muaj cov qauv ntawm cov hniav kawg: qhov kawg hniav zawj. Hauv daim duab 3-13, lub voj voog liab yog qhov kawg hniav zawj.
