Technical term for the continuous or interval movement of tools in machines. The movement can be back and forth, up and down and to the right and left. The oscillation is usually realized by pneumatic cylinders and electric motors.
Application in sanding machines
- Aggregate with sanding belt
- Better utilization of abrasives (usually sanding belt): Only rarely, the entire sanding width is used. By the oscillation of the sanding belt, the abrasive particles on the edges are also used.
- More even sanding result: Dirt or outbreaks of abrasive particles leave traces on the wood surface. By oscillation, these traces are erased by the following abrasive grains.

- Brushing unit
- Cleaning brushes: Here, the oscillation causes an uniform wear of the brush and a more thorough cleaning by the superposition of the straight forward feed direction with sideways directed movement of the brush.
- Glazing brush: Here, the same effect on the workpiece quality is achieved as reached by sanding belt oscillation.
- Blow-off device: The right-left-movement of the nozzle suspension causes the even blow-off of the wood dust from the sanding belt and thus, allows for a lower number of nozzles than without oscillation to completely cover the sanding belt width. This helps to save compressed air.
