What is the orange peel phenomenon, is a common problem encountered in daily die polishing process is excessive polishing, is refers to the polishing time is long, mold surface quality is poorer, polishing occurred over two phenomena: that is orange peel and pitting. Then we doubt what is the orange peel phenomenon? Caused by excessive mold surface overheating or carburizing, the polishing pressure over and polishing time is too long is main reason resulting in the "orange peel", embodied in the light guide plate polishing, pitting the workpiece often because a steel hard and brittle oxide leads to the formation of, so the cause of pitting is generally polishing pressure, long time, high purity steel mold surface rust and so on. How to solve this problem? A. carefully to the surface of the grinding, sand particle size than the previously used for particle size slightly coarse level by soft and cut sharp stone for the final step of grinding and polishing. B.. When the sand size is less than 1mm to avoid the use of the most soft polishing tool. C. as far as possible the use of the shortest polishing time and the smallest polishing. Because of the excessive time polishing workpiece material hardness is different, can adopt two methods to eliminate the already produced orange peel: A. to remove the defects of the surface, the size of the grinding particle size than the previous use of a slightly rough level, then grinding, polishing the size of some of the lower. B. at the temperature below the tempering temperature of 25oC stress area, in the use of the most fine polishing before grinding, and finally to the lightest of the intensity of polishing.
