Vim li cas horizontal Machining Center zoo dua rau qhov hnyav- txiav?

Kab rov tav Machining Center (HMC) ua tau zoo nyob rau hauv hnyav- lub luag haujlwm machining feem ntau vim nws "transverse spindle + box- hom kaw-loop" tsim, uas ncaj qha hloov lub zog txiav mus rau lub hauv paus. Ib txhij, nws siv lub ntiajteb txawj nqus thiab nruj, symmetrical qauv kom ua tiav machining txuas ntxiv nrog "siab torque, siab pub, thiab nyiaj loj" yam tsis muaj qhov degradation. Tshwj xeeb, qhov no tuaj yeem suav tau hauv plaub lub ntsiab lus:

1. quab yuam- txhim kho lub voj kaw, 30% nce hauv kev khoov lub sijhawm tiv thaiv

Lub thawv - hom txaj thiab hla swb ua ib qho kev sib luag kaw lub voj voog, xa cov txiav quab yuam symmetrically raws kab. Lub sijhawm dhau los tsuas yog 1/3 ntawm lub tshuab cantilever; Nyob rau hauv tib seem, qhov zoo li qub deformation raug txo los ntawm 40%, thaum tuav qhov tseeb qhov chaw ntawm ± 0.002 hli txawm tias thaum txiav hnyav.

2. Siab -torque spindle, ob npaug ntawm cov khoom tshem tawm tus nqi

Standard configuration: BT50/HSK-A100 mechanical spindle, 40-60 kW, 1000 Nm output, depth of cut up to 10 mm, feed rate 0.6 mm/z; titanium alloy housing achieves a heavy-duty material removal rate >400 cm³ / min, 80-100% siab dua ntsug milling tshuab ntawm tib lub zog.

3. Lub ntiajteb txawj nqus nti tshem tawm, tiv thaiv clogging hauv cov kab noj hniav sib sib zog nqus

Kab rov tav spindle tso cai rau chips poob ncaj qha mus rau hauv qab kauv nti chute. Ua ke nrog 70 bar hauv nruab nrab cua txias, ntev, coiled chips yog tawg mus rau hauv 30-50 mm ntu, zam kev txiav theem nrab thiab ncua lub neej ntawm 15-20%. Cov kab noj hniav sib sib zog nqus tuaj yeem ua tiav hauv ib qho dhau los.

4. Loj -span linear guides + damped txaj: txo kev vibration thiab zoo khaws cia

Cov menyuam cov kab ntawv qhia (55/65 mm qib, ncua ntau dua lossis sib npaug ntawm 600 mm) thiab lub txaj uas muaj cov ntxhia los yog cov txheej txheem sib xyaw ua kom txo qis kev vibration thaum txiav hnyav los ntawm 40%. Ncaj nraim nyob ntawm 0.01 mm / 1000 mm nyob rau hauv 10 m stroke, ntsib IT6-IT7 tolerances rau tsheb thiab lub zog tsheb vaj tse.

HMC siv plaub yam khoom siv kho vajtse tseem ceeb: symmetrical kaw-voj quab yuam khiav, siab-torque ntxaiv, lub ntiajteb txawj nqus nti tshem tawm, thiab loj-span damping. Qhov no kaw - lub voj kev tswj ntawm lub zog, cua sov, thiab chips thaum lub sij hawm txiav hnyav ua rau nws tshwj xeeb tshaj yog haum rau kev ua haujlwm tsis tu ncua ntawm cov nyiaj loj, qhov tob tob, thiab cov ntaub ntawv nyuaj. Nws yog qhov kev nyiam tshaj plaws rau kev ua tiav ob qho tib si kev ua tau zoo thiab qhov tseeb hauv hnyav - lub luag haujlwm tsheb, lub zog, thiab cov vaj tsev nyob hauv aerospace.
