Yuav ua li cas kom tsis txhob hlawv ntawm txiav workpieces?

Lub txiav disc yog ua los ntawm cov resin raws li cov binder, supplemented los ntawm iav fiber mesh, thiab ua ke nrog ntau yam ntaub ntawv.Nws qhov kev ua tau zoo yog qhov tseem ceeb tshwj xeeb rau kev txiav cov ntaub ntawv nyuaj xws li alloy steel thiab stainless hlau.Qhuav thiab ntub txoj kev txiav ua rau qhov raug txiav ntau ruaj khov.Nyob rau tib lub sijhawm, kev xaiv ntawm cov khoom siv txiav thiab hardness txhim kho kev txiav thiab txo cov nqi tsim khoom.Tab sis thaum lub sij hawm txiav, tej zaum kuj yuav muaj xwm txheej rau workpieces raug hlawv.

Peb yuav ua li cas kom tsis txhob kub hnyiab thaum lub sij hawm txiav, uas tuaj yeem cuam tshuam qhov kev txiav txim siab tsawg dhau?

1, Kev xaiv hardness

Yog tias qhov hardness siab dhau lawm, cov qauv metallographic ntawm cov khoom yuav raug hlawv, thiab cov microstructure ntawm cov khoom tsis tuaj yeem raug kuaj kom raug, ua rau muaj kev ua yuam kev;Yog hais tias lub hardness tsawg dhau lawm, nws yuav ua rau tsis tshua muaj kev ua tau zoo thiab pov tseg cov hniav txiav.Txhawm rau tiv thaiv kev kub nyhiab thiab kev ua kom pom tseeb thaum lub sijhawm txiav, tsuas yog qhov hardness ntawm cov khoom yuav tsum tau kuaj thiab siv cov coolant kom raug.

2 、 Kev xaiv cov khoom siv raw

Cov khoom siv zoo dua yog aluminium oxide, thiab silicon carbide yog qhov zoo dua rau kev txiav cov khoom tsis yog hlau thiab cov khoom tsis yog xim hlau.Vim tias cov khoom siv aluminium oxide siv los txiav cov ntaub ntawv hlau tsis hnov ​​​​mob nrog cov tshuaj lom neeg hauv cov hlau, nws muaj txiaj ntsig zoo rau kev txiav.Cov hlau tsis muaj hlau thiab cov hlau tsis muaj hlau muaj cov tshuaj lom neeg tsawg, thaum cov ntaub ntawv silicon carbide muaj cov tshuaj lom neeg tsawg dua piv rau alumina, kev ua haujlwm zoo dua, kev kub hnyiab, thiab hnav tsawg dua.

3, Kev xaiv ntawm granularity

Xaiv qhov loj me me yog qhov zoo rau kev txiav.Yog xav tau sharpness, coarser grain loj yuav xaiv tau;Yog hais tias txiav yuav tsum tau siab precision, abrasive nrog finer particle loj yuav tsum tau xaiv.
