Vim li cas thiaj yuav tsum tau CNC Parts Machining Tawm Ib Machining Allowance ntawm Lub Workpiece

Lub thickness ntawm cov hlau txheej tshem tawm nyob rau hauv txhua tus txheej txheem ntawm CNC qhov chaw ua yog hu ua machining pub ntawm cov txheej txheem. Rau kev hloov pauv xws li lub voj voog sab nrauv thiab qhov, qhov nyiaj siv ua haujlwm yog ntsuas los ntawm txoj kab uas hla, yog li nws yog hu ua symmetry nyiaj pub dawb (piv txwv li, ob sab nyiaj pub dawb), uas yog, lub thickness ntawm cov hlau txheej tau raug tshem tawm yog ib nrab ntawm cov nyiaj machining ntawm lub txoj kab uas hla. Qhov nyiaj pub rau machining ntawm lub dav hlau yog qhov nyiaj pub rau ib sab, uas yog lub thickness ntawm cov hlau txheej uas tau muab tshem tawm tiag tiag.

Txoj cai ntawm kev tso cai rau kev ua haujlwm ntawm lub tshuab ua haujlwm yog tshem tawm cov kev ua haujlwm tsis raug thiab sab nraud uas tau tso tseg los ntawm cov txheej txheem dhau los, xws li cov txheej txheem txias txias, porosity, thiab xuab zeb txheej sab nraud ntawm qhov casting, oxide nplai, decarburization txheej, thiab cov kab nrib pleb sab nraud. sab nraud forging, thiab sab hauv kev nyuaj siab txheej thiab sab nraud roughness tom qab txiav. Tom qab ntawd ua ntej qhov tseeb ntawm lub workpiece thiab sab nraud roughness. Qhov loj ntawm qhov nyiaj pub rau machining muaj qhov cuam tshuam zoo rau kev ua haujlwm zoo thiab lub zog tso zis.

Qhov nyiaj pub rau machining loj dhau lawm, uas tsis yog tsuas yog ua kom lub zog ntim ntawm machining, txo cov txiaj ntsig, tab sis kuj nce kev noj cov khoom, khoom siv thiab hluav taws xob, thiab CNC machining nce tus nqi ua. Yog tias qhov nyiaj pub dawb ntawm machining tsawg dhau, nws tsis txaus los tshem tawm txhua yam kev tsis zoo thiab qhov tsis raug hauv cov txheej txheem dhau los, thiab nws tsis txaus los them nyiaj rau qhov yuam kev clamping thaum lub sijhawm ua cov txheej txheem no, tsim cov khib nyiab. Cov txheej txheem rho tawm yog los xyuas kom meej qhov zoo ntawm qhov chaw ntawm CNC machining, kom cov npoo me me li sai tau. Feem ntau hais lus, qhov ntau refined lub machining, qhov me dua cov txheej txheem nyiaj.

Thaum txiav txim siab CNC machining ib ntus, nws tseem yuav tsum tau qhia meej seb qhov yuav tsum tau ua ntej ua ntej machining. Pre-machining feem ntau ua los ntawm cov cuab yeej siv tshuab zoo tib yam. Yog tias qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Lub sijhawm no, kev faib cov txheej txheem ntawm CNC tshuab cuab yeej yuav tsum tau txiav txim siab raws li qhov tseeb ntawm qhov kev ntsuas qhov tsis zoo ntawm qhov khoob, yog li ib txheej txheem lossis ob peb txheej txheem tuaj yeem ua tiav.
