Grinding and smoothing the edges of large metal rings.

Industrial metalworking facility with concrete floors, metal conveyor tracks, and stacks of finished or semi-finished metal rings. The area is lit by overhead industrial lights.

The worker uses both hands to grip, lift, and rotate the metal rings. They use their arms and upper body to apply pressure and guide the ring against the grinding machine.

Large, thick-walled cylindrical metal rings, likely made of steel. They are heavy, rigid, and approximately 15-20 inches in diameter.

A stationary dual-wheel industrial grinding machine.

Moderate to high precision; the worker must maintain a consistent angle and pressure while rotating the ring to ensure a uniform grind around the entire circumference.

Station-based workflow where the worker processes individual items. Another worker is seen assisting with moving and stacking the heavy rings.

1. 01Lift a heavy metal ring from the floor or a stack.
2. 02Position the ring against the rotating wheels of the stationary grinder.
3. 03Rotate the ring manually while keeping it in contact with the grinding wheels.
4. 04Apply pressure to remove burrs or smooth the edges, creating visible sparks.
5. 05Inspect the ground edge visually or by feel.
6. 06Set the finished ring aside on the floor or a conveyor belt.
