Latest Patents

One of Kun Tang's latest inventions is the "Electrochemical discharge-assisted micro-grinding device for micro-components of brittle and hard materials." This device includes a micro-grinding tool, grinding fluid, a workpiece, an auxiliary electrode, a processing groove, and a pulsed DC power supply. The processing groove is filled with grinding fluid, and the micro-grinding tool, workpiece, and auxiliary electrode are immersed in this fluid. The micro-grinding tool consists of a conductive grinding tool base, an electroplating layer, and insulated superabrasives. The tool is connected to the negative electrode of the pulsed DC power supply, allowing for efficient micro-grinding of brittle and hard materials.

Another significant patent is the "Electrochemical discharge-enabled micro-grinding process for micro-components of silicon-based materials." This invention describes a specific machining method where a micro-grinding tool and an auxiliary electrode are connected to the negative and positive electrodes of a pulsed DC power supply, respectively. The process involves an electrochemical hydrogen evolution reaction that generates hydrogen bubbles, which coalesce into an insulating gas film. This film separates the micro-grinding tool from the grinding fluid, and when the critical voltage is reached, an electrochemical discharge occurs, allowing for the ablation of surface material on the workpiece.
