02.07.2020For grinding applications, a minimum grinding angle of 30 degrees is essential. This is what is termed the angle of attack. The optimal range is between 30 and 40 degrees to the surface. Should you increase the angle of attack, the disc will be dressed more and the effectiveness of the grind will be reduced. This could also lead to chatter marks and large,
