Tungsten Carbide Blank Ball
Description
Tungsten carbide blank ball is a kind of tungsten carbide products under sinterred status, which with high density, long lifetime and high wear resistance. The surface o tungsten carbide blank ball have not polished, it is suitable for most materials of grinding, both reached the high grinding efficiency, while more durable life, reflecting the high cost.
Features
High roundness, high accuracy, high compactness, high hardness, high wear resistance and long service life.
Specifications and Tolerances
The smallest size of tungsten blank ball is Ø2mm, the general size tolerances of blank ball is ±0.2mm. But the tolerances are also accept customize.
