How Surface Grinders Machine Works

Surface grinders use a rotating abrasive wheel to remove material from a workpiece. The process involves several critical parameters, such as:

• Wheel speed moving: The speed at which the grinding wheel rotates.
• Feed rate ratio: The speed at which the workpiece is fed under the grinding wheel.
• Depth of cut of components: The thickness of the material removed in one pass.

The precision of these variables determines the quality of the finish and the accuracy of the dimensions.
