Tungsten carbide corrugating roller manufacturing process

Different from the traditional corrugating roller, the new tungsten carbide corrugating roller process is different from the traditional corrugating roller in that the hardness of the heat treatment in the front substrate is different, and the precision of the tooth profile before the spraying is higher. It must be completed on a fully automatic CNC grinding machine. The second spraying technology is the key to ensure the hardness of the tungsten carbide The force and the quality of the post-polishing process, the most difficult to process is the post-spray polishing technology, because the corrugating roller is different from the general workpiece, its unique tooth profile and surface hardness (such as diamond) of tungsten carbide, the traditional common Grinding wheel can not be carried out at all.
