AI Technical Summary
In existing polishing clamping devices, uneven contact between the metal support and the clamp, and uneven current density distribution result in uneven polishing dimensions, poor local shape, and insufficient contact between the intersection of the dense mesh support and the polishing fluid.
A dense mesh support electrochemical polishing fixture was designed, comprising an inverted conical cylindrical electrode plate and a slider push-twist structure to ensure full contact between the support and the conductive electrode plate. By changing the position of the intersection point of the support, it is made to fully expose it in the polishing liquid, thereby solving the problem of poor contact.
This achieves uniform polishing of the support surface, improves the polishing effect, ensures that each intersection can effectively contact the polishing fluid, and avoids the problem of insufficient local polishing.
