What is Dressing and Why Does Your Grinding Wheel Need It?

Using dressing throughout the grinding process is important to consistently produce parts with the required size and surface finish. Instead of replacing the entire grinding wheel, a process called "dressing" is used to restore the wheel. Dressing returns the grinding wheel to its original sharpness by removing old grains to reveal the ...
