Bearings are used in all areas to facilitate rotation, ensure energy efficiency and reduce friction. It is used in EDM machines where movement is required such as reel movement, wire feed, wire evacuation. Bearings are elements that exposed one of the most load and must be renewed continuously.
When engine running voltages reach a level that is sufficient to overcome lattice's grease characteristics, they are discharged towards motor housing along the least resistant path. When voltage level exceeds fault voltage level or fault threshold of the bearing lubrication operation, lubrication begins to oxidize. Changes in bearing lubrication, humidity, temperature and bearing component spaces will change this distortion threshold. Oxidation of the bearing oil causes distortion of the lubricant and forms a pipeline or pathway to flow through the shaft current. Therefore, long-lasting and high-quality bearings should be used, and periodic maintenance should be considered.
