What’s the difference between truing and dressing

Most people thought that truing and dressing are just the same, especially when it comes to the grinding wheel. That is because truing and dressing can be done or applied at the same time. For an instance, some resin and metal bonded products are trued offline and can be dressed afterward. But it is important, that you know its differences. The two terms involve different processes.

Truing deals with the form of the grinding wheel. During routine truing on a grinding application, the wheel's profile or form is being corrected as it compensates for the loss forms, especially when the wheel broke down. This is to ensure that the geometrical form and dimensioning specs are ready for their next application.

On the other hand, dressing is done to restore or alter the condition of the wheel's surface. Dressing deals with restoring the ability of the wheel to remove stock and generate a great surface finish. How does restoring being done? The grinding face of the wheel is dressed by exposing new and sharp cutting points that will allow the wheel to perform a high material removal rate. Now that you've learned the difference between dressing and truing, let us now focus on the process of how to true a diamond grinding wheel.
