Electroplated diamond grinding wheels stand out as indispensable tools in modern machining, prized for their precision and durability. These wheels are fabricated through an electroplating process, where diamond grains, the hardest material on earth, are bonded to a metal substrate using a thin electroplated layer, typically made of nickel or nickel-cobalt alloys.
The electroplating process starts with thorough substrate cleaning, followed by an electrochemical reaction that deposits metal layers, embedding diamond particles simultaneously. This single – layer bonding exposes the sharp diamond edges, enabling highly efficient material removal.
Their key advantage lies in precision. The uniform distribution of diamond grains ensures consistent surface finishes, making them perfect for processing hard and brittle materials like ceramics, glass, and carbide. Additionally, their exceptional wear resistance, thanks to the hardness of diamonds and the firm bond, extends the wheel’s service life.
Self – sharpening is another notable feature. As the outer diamond grains wear, new sharp edges are revealed, maintaining cutting efficiency. Widely used in semiconductor wafer grinding, jewelry shaping, and more, electroplated diamond grinding wheels continue to drive innovation in precision manufacturing.
