The disadvantage of this method of maintenance is that the oil is not easily applied evenly and the maintenance time is short. If stored for a long time, oil is easy to dry, encounter hot days will melt down the oil, the surface of the machine will encounter rusty moist air. So some machines due to poor maintenance, did not put into production before the due precision. We tried a two-layer oiled two layers of paper maintenance methods, the effect is good, no
