The oil pressure required for lubrication is controlled by the steel ball type one-way valve, and one of them passes through the fine filter and enters the lubricating oil stabilizer, and can be obtained by adjusting three throttle valves respectively. First, the oil pressure from the pipeline is reduced through the throttle slot. After the pressure oil enters the lubricating oil stabilizer, it is lubricated at the lead screw nut of the flat guide rail and grinding wheel frame, which depends on the lubrication of the pressure oil guide rail and lead screw nut output by the oil pump. Guide rail oil is suitable for mechanical equipment with guide rail device in or around itself. It is also suitable for circulating lubrication of bearings, gears and other parts.
