<p>The subject-matter of the invention is a process and a device for manufacturing relatively deep hollow spaces in solid workpieces using a laser beam, in which the material is removed by reciprocating feed movements in guide paths of the laser beam (7) which lie close beside one another. According to the invention, the laser beam (7) deflected in the vertical is pivoted about a predetermined angle during each linear stock-removal operation, and the workpiece (12) is simultaneously reciprocated in synchronism on a circular arc (14) about the pivot axis (4) of the laser beam (7). After the removal of a layer of material, these linear stock-removal operations are repeated until the predetermined depth of the hollow space is reached. With the process according to the invention, pocket-shaped or chamber-shaped hollow spaces (13) with vertical or undercut walls can be made with high stock-removal capacity in materials which are often unsuitable for machining, such as ceramics, titanium or the like. …<IMAGE>… </p> |
