(1) Txhawm rau kom ntseeg tau qhov tseeb ntawm machining, roughing thiab tiav yog nqa tawm nyias. Vim hais tias thaum lub sij hawm rough machining, qhov txiav yog loj, txiav quab yuam thiab clamping quab yuam ntawm lub workpiece yog loj, lub tshav kub tiam yog loj, thiab lub machined nto muaj ib tug tseem ceeb tshwm sim ntawm kev ua hauj lwm hardening, thiab muaj ib tug loj nyob rau hauv kev nyuaj siab nyob rau hauv lub workpiece. khoom ua haujlwm. Tsis tu ncua, qhov tseeb ntawm qhov ua tiav yuav ploj mus sai vim qhov kev faib tawm ntawm kev ntxhov siab. Rau qee qhov chaw uas yuav tsum tau ua haujlwm siab machining raug. Tom qab kev ntxhib los mos thiab ua ntej ua tiav, cov txheej txheem kub qis los yog kev laus yuav tsum tau teem caij los daws kev ntxhov siab sab hauv.
(2) Tsim nyog xaiv cov khoom siv. Rough machining feem ntau yog txiav tawm feem ntau ntawm cov nyiaj machining, thiab tsis tas yuav tsum muaj qhov tseeb machining, yog li kev ua haujlwm ntxhib yuav tsum tau nqa tawm ntawm lub tshuab cuab yeej nrog lub zog siab thiab tsis tshua muaj siab, thiab cov txheej txheem tiav yuav tsum tau ua kom zoo dua qub. Tshuab dhos. Roughing thiab xov yog ua tiav ntawm cov cuab yeej siv tshuab sib txawv, uas tuaj yeem tsis tsuas yog muab kev ua si tag nrho rau lub peev xwm ntawm cov cuab yeej siv, tab sis kuj ua rau lub neej ntev ntawm cov cuab yeej siv tshuab precision.
(3) Nyob rau hauv txoj kev machining txheej txheem, txheej txheem kev kho cua sov feem ntau yog npaj. Qhov chaw ntawm cov txheej txheem kev kho cua sov yog npaj raws li hauv qab no: txhawm rau txhim kho kev ua haujlwm ntawm cov hlau, xws li annealing, normalizing, quenching thiab tempering, thiab lwm yam, nws yog feem ntau teem ua ntej machining. Txhawm rau tshem tawm cov kev ntxhov siab sab hauv, xws li kev laus kev kho mob, quenching thiab tempering kev kho mob, thiab lwm yam, nws yog feem ntau npaj tom qab rough machining thiab ua ntej ua tiav. Txhawm rau txhim kho cov khoom siv kho tshuab ntawm qhov chaw, xws li carburizing, quenching, tempering, thiab lwm yam, nws yog feem ntau npaj tom qab machining. Yog tias muaj qhov deformation loj tom qab kev kho cua sov, cov txheej txheem yuav tsum tau npaj.
