The video shows a close up shot of a machine automatically sharpening a metal saw blade. The green and silver machine has a grinding wheel that moves back and forth along the edge of the metal saw as it's held securely in place. Small sparks fly as the grinding wheel touches the blade. The shot is well lit and provides a clear view of the machinery. This clip is perfect for projects about woodworking, manufacturing, technology, metalworking and automation.
