Machined qhov chaw yog cov khoom siv kho tshuab uas tsim thiab ua tiav siv ntau yam kev siv tshuab ua haujlwm, feem ntau yog siv cov txheej txheem uas tsis koom nrog cov txheej txheem tshuaj (los yog cov tshuaj tiv thaiv me me). Manual processing thiab numerical control processing yog ob hom tseem ceeb hauv machining.
Thaum peb tham txog kev ua cov ntaub ntawv sib txawv ntawm tus kheej, peb txhais tau tias siv cov cuab yeej xws li milling tshuab, tshuab dhos, tshuab drilling, thiab saws uas yuav tsum tau ua haujlwm los ntawm cov neeg ua haujlwm nrog cov cuab yeej siv tshuab. Cov khoom me me thiab cov khoom siv ncaj nraim yog cov neeg sib tw zoo rau kev ua haujlwm ntawm phau ntawv.
Lo lus "numerical control machining" (CNC) piav qhia tias cov kws kho tshuab siv cov lej tswj cov tshuab ua haujlwm li cas. Tshuab chaw, tig thiab milling chaw, xaim EDM cov cuab yeej, xov txiav tshuab, thiab lwm yam. Kev ua haujlwm tsis tu ncua ntawm cov khoom ua haujlwm thaum lub sijhawm CNC machining ua rau nws zoo tagnrho rau kev ua cov khoom loj loj nrog cov ntaub ntawv nyuaj.
Technical Requirements rau Machining:
1. Kev kam rau siab
(1) Unfilled shape tolerances yuav tsum ua raws li GB1184-80 specifications.
(2) Qhov ntev ntawm qhov tsis muaj cim muaj qhov ua siab ntev ntawm 0.5mm.
(3) Cov ntxhib casting qhov tseem ceeb ntawm qhov loj me yog symmetrical rau qhov chaw ua haujlwm siab.
2. Yuav tsum tau txiav workpiece
(1) Cov khoom yuav tsum tau kuaj xyuas thiab pom zoo raws li tus txheej txheem; lawv tsuas yog mus rau theem tom ntej tom qab dhau nws qhov kev tshuaj xyuas.
(2) Burrs tsis raug tso cai rau ntawm cov khoom uas tau kho.
(3) Thaum muab cov khoom tiav lawm, yuav tsum tau txais kev txhawb nqa thiab kev tiv thaiv. Cov khoom tiav yuav tsum tsis txhob muab tso ncaj qha rau hauv av. Qhov chaw kho tsis tuaj yeem muaj qhov tsis zoo xws li xeb, npauj, pob, lossis khawb uas cuam tshuam kev ua haujlwm, lub neej ntev, lossis kev ntxim nyiam.
(4) Dov qhov ua tiav nto; txheej txheem yob tawm yuav tsum tsis muaj tev tawm.
(5) Tom qab kev kho cua sov hauv cov kauj ruam kawg, yuav tsum tsis txhob muaj qhov ntsuas ntawm qhov chaw ntawm cov khoom. Nws tsis pom zoo kom anneal tiav mating nto los yog hniav nto.
(6) Cov xov xov kho tsis tuaj yeem muaj qhov tsis zoo xws li daim tawv nqaij dub, pob, chaotic buckles, lossis burrs.
