  • Process and device for the manufacture of cavities in workpieces through laser beams
    Patent number: 5225650
    Abstract: The invention concerns a process and a device for the manufacture of relatively deep cavities in massive workpieces through a laser beam, whereby the material is removed by the laser beam (7) in close guide paths. According to the invention, during each linear ablation process the laser beam (7) deviated vertically is rotated by a predetermined angle while the workpiece (12) is moved back and forth synchronously on a circular path (14) around the rotating axis (4) of the laser beam (7). Upon ablation of a material layer, these linear ablation processes are repeated until the predetermined depth of the cavity has been reached. According to the invention, pocket-like or chamber-like cavities (13) with vertical or undercut walls can be produced with considerable ablation performance in often inappropriate materials such as ceramics, titanium, etc.
    Type: Grant
