Koj paub ntau npaum li cas txog kev xav tsis zoo thiab cov ntsiab lus ntawm kev kub ceev milling?
Hauv kev tsim khoom lag luam, muaj ntau qhov kev xav tsis zoo txog kev kub ceev milling, xws li cov hauv qab no:
High-speed milling tsuas yog ib lub tshuab milling nruab nrog lub siab ceev spindle
Qhov siab dua qhov spindle ceev, qhov ua kom ceev ceev
High-speed milling tshuab yog ib tug tshiab technology, tsuas yog los hloov cov tsoos milling tshuab
A 20, 000-rpm spindle yog txaus rau pwm tsim cov kev xav tau.
Kev kub ceev milling tsuas yog ua kom nrawm los ntawm kev ua kom lub axial server
Kev kub ceev milling tsuas tuaj yeem ua cov electrodes
………
Qhov tseeb, kev kub ceev milling yog ib lub tshuab tshiab thiab kev siv lub tswv yim:
Yog tias koj xav coj tawm qhov ua tau zoo ntawm kev kub ceev txiav, koj yuav tsum ua haujlwm ze nrog txhua qhov txuas. Yog tias ib qho ntawm cov kev sib txuas tsis zoo sib xws, koj yuav tsis tuaj yeem coj tawm qhov kev ua tau zoo ntawm kev kub ceev txiav.
High-speed tool tuav thiab cutters
kev kub ceev spindle
Lub zog loj X, Y, Z axes
High-speed CNC maub los
high-speed programming zoo
Qhov xwm txheej thaum lub sij hawm high-speed txiav
Raws li kev sib hloov ceev nce mus rau ib theem, qhov kub thiab txias ntawm lub cuab yeej yuav maj mam txo. Qhov no tshwm sim yog siv nyob rau hauv high-speed milling tshuab.

Daim ntawv thov ntau ntawm kev kub ceev milling
1) Txhawm rau kom phim cov spindle specifications thiab xyuas kom ruaj ntseg thiab kev nyab xeeb ntawm kev ua, lub cuab tam txoj kab uas hla tsis tshaj 16 hli (HSK-E40).
2) Piv nrog rau cov tsoos milling, qhov kev tshem tawm ntawm high-ceev milling yog me me, uas yog heev haum rau me me qhov chaw thiab pwm ua daim ntaub ntawv.
3) Nws tuaj yeem siv rau hauv kev ua haujlwm tshiab xws li kev ua cov ntawv nyias thiab micro ua.
4) Nws yog lub tswv yim tshiab ua cov txheej txheem rau cov ntaub ntawv mos lossis cov ntaub ntawv nyuaj.
Piv txwv li: Ib qho txhuas uas muaj phab ntsa tuab ntawm 0.5 hli yuav tsis raug tsim tsis muaj kev siv tshuab milling ceev.
1. Kev kub ceev sib piv cov cuab yeej tuav thiab cov cuab yeej
Qhov tseeb, nws tsis yog lub tshuab uas ua qhov txiav, tab sis lub cuab yeej! Cov cuab yeej zoo li lub tsheb log tsheb, tsuas yog qhov chaw ntawm lub tsheb uas kov hauv av. Cov log tsheb zoo thiab tsim nyog yog tus yuam sij rau kev ua tiav hauv kev sib tw. Kev xaiv cov cuab yeej txiav thiab kev ua haujlwm tuaj yeem ua raws li cov ntaub ntawv muab los ntawm cov cuab yeej txiav, tab sis tus neeg siv tseem yuav tsum tau hloov kho raws li kev ua haujlwm tiag tiag.
Cov txheej txheem rau xaiv cov cuab yeej:
Txoj kab uas hla (raws li workpiece geometric qhov ntev thiab qhov tseeb)
Hom (roughing, xov, grooving, 3D contouring, ntug machining ...)
Puab (pob cutter, round ntswg cutter, multi-ntug milling cutter...)
Cov ntaub ntawv (kev kub ceev steel, cemented carbide, cermet, pob zeb diamond, cubic boron nitride CBN)
Cov cuab yeej txheej (TiN, TiCN, TiAlN...)
Kev ua tau zoo (radial runout, zoo li qhov tseeb, dynamic tshuav, rigidity)
2. High-speed spindle
Qhov tseeb, lub siab ceev spindle zoo li lub siab ceev thiab lub zog ntawm lub cav hauv lub tsheb sib tw F1.
Spindles tuaj yeem muab faib ua ob qhov tshwj xeeb:
1) Nrog bearings Ntau dua lossis sib npaug ntawm lub zog siab, qhov siab tshaj plaws tam sim no tuaj yeem ncav cuag 54, 000 rpm.
2) Bearingless (gas driven) ≥ low torque, but very fast speed (>100 krpm).
Siab torque tso cai rau kev txiav cov ntaub ntawv loj, siv cov cuab yeej loj thiab cov ntaub ntawv nyuaj. Kev sib hloov ceev tso cai rau txiav cov nqi nrawm dua thiab ua tiav HSM cov teebmeem.
3. High dynamic kev ua tau zoo ntawm txhua axis
Qhov tseeb, lub txaj qauv ntawm lub tshuab nws tus kheej zoo li lub chassis ntawm lub tsheb, muaj zog thiab muaj kev nyab xeeb kom nqus tau qhov poob siab thiab kev co.
Traditional nyuaj rails tuaj yeem ua tiav qhov raug zoo dua los ntawm kev hloov kho ntawm lub rooj tshuab, tab sis lawv tsis tuaj yeem ua tiav qhov kev ua haujlwm siab uas cov kab swb tuaj yeem ua tiav. Nrog kev kub ceev axes thiab cov qauv txaj, acceleration yog qhov tseem ceeb. High-acceleration axes txo lub sij hawm pov tseg, muab qhov chaw txiav zoo dua, thiab txo cov cuab yeej hnav.
4. Kev kub ceev milling maub los CNC
Qhov tseeb, tus maub los zoo li tus neeg tsav tsheb, thiab nws cov kev txawj ua haujlwm txiav txim siab qhov tshwm sim ntawm lub tsheb. Nws xav tau kev pom, rhiab heev thiab muaj peev xwm teb tau sai.
5. CAM ua lub tswv yim rau kev kub ceev milling
Qhov tseeb, muaj ntau txoj hauv kev kom tau los ntawm ib qho mus rau lwm qhov, tab sis txhua txoj hauv kev yuav muaj qhov sib txawv ntawm kev ceev, nto, thiab lwm yam.
