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.

generation grinding all axes are moved, however, the grinding wheel is not infed in the sense of grinding stock. • Plunge grinding Plunge grinding is a discontinuous grinding process, machining is also performed tooth by tooth. Both tooth flanks are machined simultaneously. There is a surface contact between tooth flank and grinding wheel.
TYPES OF GRINDING WHEELS
PLUNGE GRINDING. Conventional grinding machines can be broadly classified as: (a) Surface grinding machine ... Truing is the process of changing the shape of the grinding wheel as it becomes worn from an original shape, owing to the breaking away of the abrasive and bond.
What is Polishing and Define the Process
A process to generate a reflective surface. Normally, the polish is generated by using a fine-micron or sub-micron abrasive particle in combination with a liquid. Polishing is a "wet" process. Often the polishing process utilizes a pad to contain the abrasive, so polishing may not be a "loose abrasive process.". The pad is softer than ...

Machining 101: What is Grinding? | Modern Machine Shop
Infeed grinding (also called plunge centerless grinding) is best when a workpiece has projections, irregular shapes, varying diameters or shoulders, and works best for profiles and multi-diameter workpieces. In this submethod, feed wheels above the grinding wheel feed the workpiece downward, with no lateral movement during grinding.
