Tsis yog tag nrho cov ntaub ntawv yuav precision machined. Qee cov ntaub ntawv nyuaj heev uas lawv dhau qhov ntau ntawm hardness rau machining. Yog li ntawd, cov ntaub ntawv no tsis haum rau precision machining. Kuv yuav tsum xyuam xim rau dab tsi thaum xaiv cov ntaub ntawv nyob rau hauv lub teb ntawm precision machining?
Cov ntaub ntawv siv rau cnc precision machining qhov chaw feem ntau muab faib ua ob pawg: cov khoom siv hlau thiab cov khoom tsis yog xim hlau. Rau cov khoom siv hlau, lub hardness kuj yog siab heev ntawm stainless hlau thiab carbon hlau, ua raws li cam khwb cia hlau, dua tooj liab, thiab thaum kawg txhuas; thiab ceramics thiab yas ua yog cais raws li cov khoom siv tsis yog hlau.
Ua ntej, qhov yuav tsum tau ntawm cov khoom hardness. Hauv qee qhov tshwj xeeb, qhov siab dua qhov hardness ntawm cov khoom, qhov zoo dua. Nws yog txwv rau hardness yuav tsum tau ntawm machined qhov chaw. Cov khoom siv machined yuav tsum tsis txhob hnyav dhau, yog tias nws nyuaj dua li cov khoom siv lub tshuab lossis cov cuab yeej siv tshuab tsis tuaj yeem machined.
Qhov thib ob, seb cov khoom puas tsim nyog, tsawg kawg yog ib theem qis dua cov khoom siv tshuab thiab cov cuab yeej siv tshuab, tab sis kuj yog nyob ntawm kev ua haujlwm ntawm cov khoom siv thiab cov txheej txheem ua haujlwm.
Precision qhov chaw ua rau cov khoom siv khoom muaj qee yam yuav tsum tau ua, tsis yog txhua cov ntaub ntawv tsim nyog rau kev siv tshuab ua haujlwm, cia peb hais tias cov khoom muag muag dhau los yog cov khoom siv tawv dhau, mos heev tsis tsim nyog, nyuaj heev yuav ua rau cov khoom siv tsis tuaj yeem ua tiav ntawm nws.
Yog li ntawd, nyob rau hauv lub teb ntawm mechanical qhov chaw ua, qhov ceev ntawm cov khoom yuav tsum tau to taub ua ntej ua cov khoom. Yog hais tias qhov ceev yog siab dhau, qhov sib thooj hardness yuav siab dua. Yog hais tias lub hardness ntau tshaj qhov hardness ntawm lub tshuab cuab yeej, machining yog tsis tau. Nyob rau hauv rooj plaub no, kev ua haujlwm yuav tsis tsuas yog ua rau cov khoom puas xwb, tab sis kuj ua rau lwm yam kev phom sij, xws li cov cuab yeej tawg, kev puas tsuaj rau lub tshuab cuab yeej, thiab lwm yam. Yog li ntawd, hauv kev ua haujlwm, cov khoom siv yuav tsum qis dua qhov hardness. cov cuab yeej, kom cov khoom tsim nyog rau precision machining.
