缠绕垫片石墨带采用高精度数控车床用特殊刀具把石墨卷材切割成带状,与传统的石墨开条相比,精度更高,对石墨卷材造成损伤较小,切割部位光滑无毛刺,用于生产石墨缠绕垫片填充材料.
Graphite tape for SWG use high precision CNC lathe to cut graphite coils into strips with special cutting tools,Compared with traditional graphite strips,higher accuracy,less damage to graphite coils,smooth cut without burrs,used to produce graphite spriral wound gasket filling material.
