The thicker the mirror roller, the better the effect, but also the higher the processing cost. However, the melting point of the mirror roller has nothing to do with whether its surface is mirror-like; the main factors affecting the melting point are the composition and its content. The mirror spark machine is a type of equipment that processes mirror rollers at a faster speed. Yet, due to the heavy workload, many companies try to increase the processing efficiency of the mirror spark machine. In fact, there are several methods to improve it, but many people are unaware of them. Below is an introduction to the processing methods of mirror rollers.
Utilizing oil stone, diamond polishing compound, and various brands of sandpaper, achieve a glossy surface finish through coarse, medium, and fine grinding with polishing and grinding equipment. Mirror roller quality standards: free of sand and lumpy particles. The surface should be flat, without any undulations or wavy surfaces. No sand holes, impurity spots, dents, or scratches. The brightness of the mirror roller reaches 8K, with the polished mirror surface brightness exceeding 8K. Term explanation: The "8" in 8K refers to the proportion of alloy composition, while "K" denotes the reflectivity level achieved after polishing. An 8K mirror represents the level of reflection in chrome-nickel steel.
The concept of the "red" mirror roller is rather vague. Various metals are considered "red" when they are not very shiny at around 400℃. Therefore, the "burned mirror stainless steel red" is likely achieved at around 400 degrees. As the decorative building materials market continues to evolve, the application scope of mirror rollers expands. However, there are numerous processing and installation methods for mirror rollers, and key points to be aware of on the construction site should be promoted together. The pre-treatment of the decorative surface of the mirror roller before bending often leads to surface undulations and inconsistent reflectivity, affecting the appearance. There are many reasons for this phenomenon, and most people believe it is due to the material being too thin. However, it is not actually because there was no pre-treatment before bending the sheet.
Mirror roller processing involves minimal mechanical force, making it suitable for low-stiffness workpieces and delicate structures. Pulse parameters can be adjusted as needed, with rough, semi-fine, and fine processing all possible on the same machine. The surface dimples after electrical discharge machining are beneficial for oil storage and noise reduction. Production efficiency is lower than that of cutting. During the discharge process, the tool electrode consumes some energy, leading to electrode wear and affecting forming accuracy. Some mirror roller mold steels can easily achieve a mirror finish through electrical discharge machining, while others cannot reach a mirror finish no matter what.
