Abstract

The invention relates to an apparatus for machining material by means of a laser beam (13), having an optical element (5) arranged in an optic housing (1) and having a guide (4) for a linear adjustment drive (6) that is movable in the Y direction laterally to the beam propagation direction (14) that takes place in the Z direction. In order to improve the apparatus with regard to even more precise alignment of the laser beam with the TCP (Tool Centre Point), a second guide (3) for a linear adjustment drive (2) that is movable in the Z direction parallel to the beam propagation (14) that takes place in the Z direction is provided, such that an adjustment of the optical element (5) and thus of the laser beam (13) in two directions, i.e. in the Y and in the Z direction, at the same time is possible.
