How to Processing Precision Dies

The precision mold & machining process is the last process of die processing, and it is the most important one that directly affects the quality of the die. It accounts for about 30%-40% of the total amount of die processing. Therefore, it is highly valued by experts at home and abroad. In our country, although most of the processes of precision mold & machining (turning, milling, planer, grinding, EDM, WEDM, etc.) have been highly automated, most of the die finishing still adopts manual processing, which seriously affects the development of our die to a certain extent.

Precision mold & machining is a method to reduce the surface roughness of parts on the premise of ensuring the surface accuracy of parts. At present, the commonly used methods are manual polishing, ultrasonic polishing, chemical, and electrochemical polishing and so on.

Among these methods, manual polishing is the most commonly used finishing method, because manual polishing has flexible movement and can process any complex cavity, but at the same time, this method has high labor intensity, low production efficiency and product quality are not guaranteed. Although other methods have good effects, from the quality of products, processing efficiency to the strength of workers have greatly improved, but because of the complexity, diversity, and irregularity of the die cavity, it is difficult for these processing tools to process along the contour line of the workpiece completely, and sometimes limited by the cavity space, so many finishing methods can only be self-contained in some fields. It is difficult to popularize and use it widely.

Most die manufacturers adopt the integration of die design, processing, and even assembly, that is, the integration of die CAD/CAM/CAE, using die CAD software and reverse engineering for design; using virtual reality system for assembly test, finding interference timely adjustment, and processing without problems; in the process of processing, using the processing center and CAD/CAM, the whole process is carried out. Processing process integration, that is, one installation of the workpiece to complete the processing of parts, so the accuracy of the workpiece can be guaranteed.

Nevertheless, the precision mold & machining problem is still a world problem.
