mirror polishing mold surface engineering technology
Die polishing technology
Die polishing technology plays a crucial role in both die surface engineering and the overall die manufacturing process.engine cnc machining
Currently, domestic polishing tools are capable of achieving a polishing level of Ra0.05μm. The abrasive abrasives and processes employed are generally sufficient to meet the requirements. However, when it comes to achieving a mirror-like polishing level of Ra0.025μm, the equipment, abrasive abrasives, and processes are still in the experimental phase.horizontal machining center cnc
Currently, domestic polishing equipment, grinding tools, and technologies have the capability to achieve an ultra-fine surface roughness of Ra0.05μm, which effectively fulfills the requirements. However, it is important to note that the exploration of the ultra-fine surface roughness of Ra0.05μm is still ongoing.5 axis cnc machining center automatic
The widespread use of mirror injection molds in manufacturing has made die polishing technology a critical concern. Due to existing challenges with polishing techniques and materials in China, including defects in lenses, injection molds, CDS, VCDS, and tools with superior transparency, a significant portion of injection molds continue to be imported.cnc service machining parts
It should be emphasized that the quality of the die surface polishing is influenced not only by the polishing equipment and techniques, but also by the mirror finish of the die material, a factor that has not received sufficient attention. Essentially, the polishing process is constrained by the mold material itself. For instance, when using 45# carbon steel as the mold material and polishing it to Ra0.2m, any visible defects can only be improved by enhancing the brightness through further polishing, as the roughness cannot be effectively enhanced. Consequently, in the current scenario, domestically produced mirror molds predominantly utilize imported mold materials like Sweden ASSAB 136, Japan Datong PD555, to achieve the desired mirror finish.cnc machining center x2000
