Tungsten Carbide Blade Grinding Crack’s Prevention III

Due to processing practice, summed up the measure that adopting fair amount of grinding sharpening can effectively prevent or reduce tungsten carbide blade grinding crack sharpening process.

If there are too much friction in tungsten carbide tool grinding sharpening process, grinding can lead to a sharp rise in temperature, the blade prone to burst, so fair selection of grinding parameters is very important. A fair amount of common ground: peripheral speed v = 10 ~ 15m/min, feed f vertical = 0.5 ~ 1.0m/min, f cross = 0.01 ~ 0.02mm / trip. When hand grinding, longitudinal and cross feed volume is not too large.
