Wheel hardness selection principle

1. The harder the workpiece, the softer the wheel.
2. The larger wheel contact with the workpiece surface, the softer the wheel selection.
3. The grinding and profile grinding wheels should choose harder to keep the wheel shape required accuracy.
Wheel hardness relationship 4. Select the particle size: the larger the size of the wheel, cut off wheel is to avoid debris blockage, generally choose a softer wheel.
5. workpiece material: When grinding non-ferrous metals, rubber, resins and other softer material should be used in a softer wheel
