When sanding a workpiece, in which direction should you move it against the rotating disc?

When sanding a workpiece against a rotating disc, moving it downward is vital for several reasons. Firstly, the design of most sanding machines promotes an effective downward motion, where the disc rotates to pull the workpiece towards it. This downward movement allows for optimal contact between the sandpaper and the surface of the workpiece, ensuring a more uniform sanding action.

Additionally, moving the workpiece downward takes advantage of gravity, which helps to enhance the sanding process. This motion allows for better control and reduces the risk of the workpiece lifting or slipping, which can occur if you sand in other directions. It also minimizes the chance of damaging both the workpiece and the sanding equipment since the force of the downward movement aligns with the way the disc is intended to operate.

In terms of safety, sanding in the downward direction reduces the likelihood of kickback or injury, as the user maintains a stable posture while operating the machinery. Overall, moving the workpiece downward against the rotating disc optimizes performance, safety, and the quality of the finish.
