FAQ
Q1: Dab tsi ntawm txoj kab uas hla kuv yuav tsum hloov ntawm dov mus rau forged bar rau qhov tseem ceeb?
A: Rau cov khoom uas muaj kev ncaj ncees sab hauv yog lub hom phiaj tseem ceeb, peb pom zooforged bar rau diameters tshaj 80-100mm. Forging ua kom cov qauv zoo li qub thiab tshem tawm qhov nruab nrab ntawm cov kab porosity, uas dhau los ua nyuaj los lav nrog dov ntawm cov kab loj dua.
Q2: Puas yog forged bar ho kim dua li dov bar?
A: Tus nqi lag luam wholesale ntawm lub forged bar yog siab dua vim cov txheej txheem ntxiv. Txawm li cas los xij, rau cov ntawv loj loj lossis kev nyab xeeb tseem ceeb heev-xws li 300mm turbine ncej- tus nqi ntawm ib qho khoom siv cuam tshuam txog qhov ua tsis tau zoo tshaj qhov kev nqis peev ntxiv hauv cov tshuaj forged.
Q3: Koj puas tuaj yeem muab GH3030 tuav nrog precision kam rau ua CNC machining?
A: Yog. Rau dov tuav mus txog 100mm, peb muabci av tiavnrog h9 los yog h10 precision tolerances, ua rau lawv npaj rau tsis siv neeg bar feeders thiab Swiss-type lathes.
Q4: Yuav ua li cas koj txheeb xyuas qhov zoo nyob rau hauv loj-inch forged tuav?
A: Peb ua100% ultrasonic kuaj (UT)Raws li cov qauv hauv aerospace (xws li, AMS 2154) kom ntseeg tau tias txhua qhov bar tsis pub muaj kev sib tsoo sab hauv, voids, suav nrog, lossis kev sib cais.
