Alignment lasers are used in wood processing machines in order to mark the application point or the path of the tool on the workpiece (e.g. cutting line). These are used in particular in individual production, whereby boring points, cutting lines and cutting paths are marked on the workpiece (e.g. staircase construction), or where the character of the wood material is of greater significance than the stop dimension (e.g. edging cuts, knothole boring).
Alignment lasers are used in machine types including the following:
| Carpentry machines | For marking the cross cut line |
| Carpentry saw benches | For marking the cross cut line |
| Straight line edgers | Help when locating the trimming cut line |
| Double edging saws | Help when locating the trimming cut line |
| Sliding table saws | Help when locating the trimming cut line or dividing cuts on workpieces with marked dimensions |
| Slot boring machines | Ease the adjustment of the spindle or table position with workpieces on which the boring point has been marked. |
| Rip saws | Help when locating the trimming cut line or dividing cuts on workpieces with marked dimensions |
| Multiblade saws | Help when locating the trimming cut line |
| Micro finger joint milling machines | For marking the cross cut line |
| Optimisation cross cut saws | For marking wood defects; more rarely: Length determination (board start and end) |
| Pendulum saws | For marking the cross cut line |
| Beamsaws | Help when locating the trimming cut line |
| Radial arm saws | For marking the cross cut line |
| Face plate saws | |
| Pale drilling machines | Projects the boring point onto the workpiece, helps with positioning the workpiece with marked bore holes on the machine table. |
| Stair trenchers | Projection of the milling track on the workpiece as target aid when milling on marked workpieces |
| Tenoning machines | For marking the cross cut line |
| Joinery tenoners | For marking the cross cut line |
| Angular window machining centres | For marking the cross cut line |
