Cov txheej txheem tsim khoom yog hais txog tag nrho cov txheej txheem ntawm kev tsim cov khoom los ntawm cov khoom siv raw (los yog cov khoom tiav semi tiav). Rau kev tsim tshuab, nws suav nrog kev thauj mus los thiab khaws cov ntaub ntawv raw, kev npaj ntau lawm, kev tsim khoom tsis muaj, kev ua haujlwm thiab kev kho cua sov, cov khoom sib dhos, thiab kev debugging, painting thiab ntim, thiab lwm yam. Cov ntsiab lus ntawm cov txheej txheem ntau lawm yog qhov dav heev. Cov tuam txhab niaj hnub no siv cov qauv thiab cov txheej txheem ntawm cov tshuab engineering los npaj thiab qhia kev tsim khoom, thiab suav nrog cov txheej txheem tsim khoom raws li cov txheej txheem tsim khoom nrog cov tswv yim thiab tawm. Nws tuaj yeem ua rau kev tswj hwm ntawm kev lag luam scientific thiab ua rau lub lag luam hloov tau yooj yim thiab sib tw.
Nyob rau hauv cov txheej txheem ntau lawm, cov txheej txheem ncaj qha hloov cov duab, qhov loj me thiab kev ua haujlwm ntawm cov khoom siv raw (lossis dawb paug) kom ua rau cov khoom tiav yog hu ua txheej txheem. Nws yog ib feem tseem ceeb ntawm cov txheej txheem ntau lawm. Piv txwv li, casting, forging thiab vuam ntawm qhov khoob; Kev kho cua sov los hloov cov khoom siv [1]; machining ntawm qhov chaw, thiab lwm yam, yog tag nrho cov txheej txheem thev naus laus zis. Cov txheej txheem thev naus laus zis yog tsim los ntawm ib lossis ntau cov txheej txheem ua ntu zus.
Cov txheej txheem yog lub hauv paus ntawm cov txheej txheem thev naus laus zis. Cov txheej txheem hu ua yog hais txog ib feem ntawm cov txheej txheem uas txuas ntxiv ua tiav rau ib lossis ib pawg ntawm cov khoom ua haujlwm ntawm qhov chaw ua haujlwm. Cov yam ntxwv tseem ceeb ntawm cov txheej txheem yog tias cov khoom ua tiav, cov khoom siv thiab cov neeg ua haujlwm tsis hloov pauv, thiab cov ntsiab lus ntawm cov txheej txheem tau ua tiav tas li. Cov txheej txheem tuaj yeem muab faib ua ob kauj ruam hauv qab no:
Txheej txheem 1: Tig lub voj voog sab nrauv, lub ntsej muag kawg, tho txawv thiab sab hauv lub qhov chamfering ntawm lub tshuab dhos;
Kauj Ruam 2: Laum 6 qhov me me ntawm lub tshuab drilling.
Nyob rau hauv tib lub lag luam, lub workpiece yuav raug ntsia ob peb zaug. Ib feem ntawm cov txheej txheem uas lub workpiece tiav nyob rau hauv ib tug clamping yog hu ua installation. Hauv kev ua haujlwm 1, muaj ob lub installation. Thawj qhov kev teeb tsa: clamp lub voj voog sab nrauv nrog peb lub puab tsaig chuck, tig lub ntsej muag kawg C, tho lub qhov sab hauv, chamfer lub puab lub qhov, thiab tig lub voj voog sab nraud. Qhov thib ob kev teeb tsa: U-tig, clamp lub voj voog sab nraud nrog peb-claw disc, lub tsheb kawg ntsej muag A thiab B, thiab chamfer lub puab lub qhov.
