Abstract
A device for deblocking optical workpieces, having a first moving device for rotating a workpiece, which is blocked on a blocking piece, about a workpiece rotational axis and a nozzle for dispensing a pressurized stream in a direction that is essentially transverse to the workpiece rotational axis onto a point of incidence in an edge region between the blocking piece and the workpiece. The device also has a second moving device for generating a relative movement between the nozzle and the workpiece. The second moving device has a nozzle guiding portion on which the nozzle is mounted and by which the nozzle can be positioned with respect to the blocking piece in a cam-controlled manner in order to aim the pressurized stream towards the point of incidence in a defined manner.
