The machine will gradually reduce machining accuracy, oil temperature, noise, bearing temperature rise, energy consumption increased in the use process. The emergence of these phenomena is mainly because the machine working process due to friction and wear the gap between the friction drive system caused by the oversized. "Solid vertical friction", can use in working process, the friction is generated on the surface of metal ceramic layer, metal ceramic layer with high hardness, good wear resistance, corrosion resistance, low friction coefficient, the friction pair surface, repair optimization gap etc.. Can reduce noise, reduce the bearing and oil temperature, save energy, reduce vibration, thus improving the processing precision, and can keep the lathe long-term high precision, saving energy, reducing oil change period, to extend the repair cycle machine etc.. Directly or indirectly to the enterprise has brought considerable economic benefits and social benefits.
