Too high Grinding Pressure

The temperature at the grinding point exceeds 1500°C and there is no cooling liquid. If the grinding pressure increases, the grinding grains enter deeper into the steel which increases consequently the temperature stress to the blade.

• Destroys the steel structure => the steel become brittle and nicks/chips can develop along the cutting edge. This leads into a bad cutting quality.
• Sparks => The intensity of sparks gets higher and the risk of fire increases

• Higher wear of the blade
• Blade deformation: As the grinding wheels go “on and off” you bring more vibrations to the blade

IMPORTANT: The advance factor (ratchet) needs to be set so that that the grinding unit “only” follows the decay and natural wear pattern of the blade. It should not force the grinding assembly / the wheels into the blade!
