Further explanation is as follows:

This project is an electronic product appearance part. Since the product surface is not allowed to have knife marks and other defects, the best choice is planing technology.

As the project also requires subsequent CNC machining of the shape, round-shank tools are used to facilitate CNC clamping of the tool holder. However, tool manufacturers have difficulty in making corrections when grinding PCD tools, and the tool yield is always unsatisfactory. Production has been temporarily suspended several times due to the low tool yield. Against this background, a special square-shank PCD planer and matching tool holder were developed.

When using the CNC machining components with the appearance of the above-mentioned metal products, while improving the machining yield and efficiency of the tool itself, the tool can be stably clamped on the surface and the force balance of the tool can be ensured during the milling process of the workpiece by the blade, thereby reducing the situation of poor machining surface caused by tool shaking and vibration during the machining process and improving the machining yield.
