How does a surface grinder hold a workpiece in place?

On a surface grinder, the workpiece is held securely in place on a moving table using one of two primary methods:

• Magnetic plate: A flat magnetic chuck or plate is commonly used to hold ferrous workpieces firmly against the table surface.
• Vise: For workpieces that cannot be held magnetically, a vise is utilized to clamp the piece in position.

Once secured, the table moves the workpiece back and forth beneath the rotating abrasive wheel to achieve the desired shape or finish.1
