Latest Patents

One of Cong Mao'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 is composed of a conductive grinding tool base, an electroplating layer, and insulated superabrasives. This innovative design allows for the production of numerous microstructures on the surface of the workpiece.

Another notable 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 a pulsed DC power supply. The process involves an electrochemical hydrogen evolution reaction that generates hydrogen bubbles, which coalesce into an insulating gas film. When the critical voltage is reached, the gas film breaks down, leading to an electrochemical discharge that ablates the surface material of the workpiece, creating a heat-affected layer.
