Tshuab dhosGH4169 (sib npaug rau Inconel 718)yog ib txoj hauj lwm nyuaj heev rau machining cov tswv khw thiabCNCcov neeg ua haujlwm. Nws tsis yog qhov tsis yooj yim rau tus nqi ntawm cov cuab yeej hnav kom dhau tus nqi ntawm cov khoom nws tus kheej.
Pain Points:
* ** Kev ua haujlwm nrawm nrawm: **Cov ntaub ntawv hardens instantly raws li cov cuab yeej sib cuag nrog lub workpiece nto. Txawm tias ib millisecond ntawm cov cuab yeej nyob rau lub sij hawm tuaj yeem nthuav tawm nws mus rau "pob zeb diamond- nyuaj" txheej, ua rau tam sim ntawd chipping ntawm ntug txiav.
** Tsis zoo Thermal conductivity:**Thaum tshav kub kub tsis tuaj yeem dissipate los ntawm cov chips thiab es tsis txhob concentrates ntawm lub cuab yeej. Qhov no ua rau "thermal softening" ntawm cov cuab yeej txiav kim.
* **High abrasiveness:**Metallurgical carbides hauv matrix ua zoo li cov ntawv xuab zeb, hnav cov cuab yeej thiab txo nws txoj sia.
NtawmGnee Steel, peb tsis tsuas yog muag cov alloys xwb tab sis kuj muab cov kev qhia tshwj xeeb thiab cov ntaub ntawv muaj los xyuas kom meej tias koj cov khoom tseem raug nqi - zoo.
