Grit Dresser

  Technical Support Product Inquiries


Grit DresserUsed along with many diamond grains so the force while dressing a grinder with diamond particles is evenly distributed and dresser wear is reduced. This enables reliable dressing and a long life. The dresser feed speed can be increased to 2 to 4 times the speed of a single-point dresser, enabling shorter dressing times.


A grit dresser can be used in centerless grinders, cylindrical grinders and surface grinders with large wheels.

Usage Tips

The dresser should be attached with the entire surface in contact with the wheel surface. A finer surface finish can be obtained using a grit dresser instead of a single-point dresser. If the surface finish is too fine, this can be remedied by increasing the dresser feed speed. Set the cutting depth to 0.03 – 0.05 mm for rough finishing and 0.01 – 0.02 mm for finishing. Be careful with the coolant supply and how firmly the dresser is attached when dressing.
