What are the traditional mold manufacturing processes?

Rough machining process The so-called rough machining process refers to the process of cutting off most of the machining allowance from the workpiece to make its shape and size close to the requirements of the finished product. Such as rough turning, rough boring, rough milling, rough planing and drilling. The machining accuracy is lower than IT 1 1, and the rough machining process with surface roughness Ra 6.3μm is mainly used for the final machining with low requirements or non-surface matching and as the pre-machining before finishing. Finishing process Finishing process is to remove less machining allowance from rough surface, so that the workpiece can achieve higher machining accuracy and surface quality. Commonly used machining methods mainly include fine turning, fine boring, reaming, grinding, electrical machining and form grinding. Repair technology Repair technology is to remove little machining allowance from the machined workpiece surface to obtain parts with high precision and surface quality. This process is generally called the final process of parts processing, and its precision and surface quality requirements should meet the requirements of mold design drawings, such as grinding guide posts and guide sleeves, polishing workpiece forming parts, etc.
