Abstract: In a method and a device for electrolytically polishing inner surfaces of a recess in a workpiece made of metal, in particular a workpiece printed in three dimensions, provision is made that a cathode is introduced into the recess and polishes the inner surface of the recess using an electrolyte having a slow diffusion rate.

Abstract: The invention relates to a device for the thermal deburring of workpieces, having at least one deburring chamber and one feeding device for introducing a fuel gas mixture into the deburring chamber. A supplementary gas supply is provided for at least the deburring chamber or for the feeding device such that the fuel gas mixture located at least in the deburring chamber or in the feeding device can be mixed at least partially with supplementary gas. Further, a method for the rapid ventilation of a device for the thermal deburring of workpieces is also provided.

Abstract: The invention relates to a method for electrochemical processing of at least one workpiece, comprising at least the following steps: a) setting a first flow density during a first phase in an electrolyte, b) retaining the first flow density during a second phase following the first phase, c) increasing the first flow density during a third phase following the second phase to a second flow density at least 30% greater than the first flow density, and d) reducing the second flow density during a fourth phase following the third phase within a maximum of 100 microseconds to a maximum of 1% of the second flow density.

Abstract: The invention relates to a method and device for obtaining a determined flow resistance of a flow channel, especially an opening in a component. The method involves the following steps: a liquid flows through the flow channel; a characteristic depending on the flow resistance of the flow channel in the component is determined; and the flow channel is machined by means of a working method until said characteristic reaches a pre-determined nominal value.
