Qhov siab ntawm automation tuaj yeem txo qhov kev siv lub cev ntawm tus neeg teb xov tooj. Cov txheej txheem NC machining tau ua tiav raws li cov txheej txheem nkag. Tus neeg teb xov tooj tsuas yog yuav tsum pib teeb tsa lub cuab yeej, thauj khoom thiab tshem tawm cov khoom ua haujlwm, thiab hloov lub cuab yeej. Nyob rau hauv cov txheej txheem machining, nws yog tsuas yog los soj ntsuam thiab saib xyuas kev ua haujlwm ntawm lub tshuab cuab yeej.
Txawm li cas los xij, vim muaj cov ntsiab lus siab ntawm CNC tshuab cuab yeej, kev ua haujlwm siab ntawm cov neeg ua haujlwm tau zoo dua qub. High precision thiab ruaj khov zoo ntawm machined qhov chaw. Qhov tseeb ntawm qhov chaw thiab rov ua qhov tseeb ntawm CNC tshuab cuab yeej yog siab heev, uas ua rau nws yooj yim dua kom ua tiav qhov sib xws ntawm qhov loj ntawm ib pawg ntawm cov khoom. Tsuav tus txheej txheem tsim thiab kev pab cuam yog qhov tseeb thiab tsim nyog, ua ke nrog kev ua haujlwm zoo, cov khoom tuaj yeem tau txais kev ua haujlwm siab, thiab nws kuj yog qhov yooj yim rau kev tswj xyuas cov txheej txheem machining.
Cov xuab zeb moulding, core sand thiab core pob txha ntawm lub casting yuav tsum tau muab tshem tawm thiab ntxuav. Yog hais tias lub casting muaj ib tug oblique txoj hauj lwm, nws dimensional kam rau ua tsam yuav tsum tau nruab symmetrically raws lub inclined dav hlau. Cov xuab zeb moulding, core sand, core pob txha, succulent nroj tsuag, nplaum xuab zeb, thiab lwm yam ntawm cov castings yuav tsum tau spaded, grinded thiab leveled, thiab ntxuav kom huv si.
Kev sib tw thiab staggering, punch casting sib txawv, thiab lwm yam yuav tsum tau hloov kho kom ua tiav qhov kev sib txuas du, thiaj li ua kom lub ntsej muag zoo. Lub folds ntawm qhov tsis ua tiav ntawm qhov casting yuav tsum tsawg dua 2 hli tob thiab qhov sib nrug yuav tsum ntau tshaj 100 hli. Cov khoom siv uas tsis yog tsim los ntawm cov khoom siv castings yuav tsum tau txhaj tshuaj blasted lossis chim dov kom tau raws li qhov yuav tsum tau ua ntawm kev huv huv sa21/2. Casting qhov chaw yuav tsum ua cov dej toughening tov. Qhov saum npoo ntawm lub casting yuav tsum tau leveled, thiab cov roj hmab inlet, burr, slag inclusion, thiab lwm yam. Casting qhov chaw tsis raug tso cai kom muaj qhov txias txias, cov kab nrib pleb, qhov thiab lwm yam tsis zoo uas cuam tshuam rau daim ntawv thov.
Yog tias cov xim pleev xim rau saum npoo hlau tuaj yeem tiv thaiv kev nkag mus ntawm dej, oxygen, cov khoom siv hluav taws xob thiab cov ions tsis zoo, nws tuaj yeem txo qis lossis tiv thaiv corrosion ntawm cov khoom siv hlau pleev xim. Yog tias qhov tseeb ntawm kev tiv thaiv tsis zoo heev, txheej txheej txheej txheej txheej tsis zoo heev rau kev tiv thaiv corrosion thiab tiv thaiv corrosion ntawm alloy. Kev xyaum ua neej qhia tau hais tias kev nqus dej ntawm cov tshuaj tiv thaiv cov txheej txheem ua rau muaj kev phom sij rau cov adhesion ntawm cov tshuaj txau ntawm cov ntaub ntawv hlau, thaum lub permeability pom tseeb ua rau lub zog corrosion ntawm cov ntaub ntawv hlau. Muaj ntau ntau hom etching ntawm cov khoom siv hlau txau, tab sis qhov ncaj qha ua rau etching yog ze ze rau cov organic chemistry thiab tshuaj ua haujlwm zoo.
