What is Plunge Grinding? | Indiana Precision Grinding
Plunge grinding is an ideal process for parts with complex geometries. How does the process itself work? The workpiece is held by a tailstock at one end and the other is clamped and rotated in a chuck. The grinding wheel then comes down—literally plunging into the workpiece—to grind and regenerate the workpiece's surface.
