First, the frictional surface of the circular guide of the machine moves the curved surface of the curve ring, which supports the entire motion load of the machine. If there is thirst oil or simmering oil, the coefficient of friction will increase greatly, which may cause biting of the moving slip surface and quickly deteriorate. Therefore, it is necessary to inject lubricating oil into its sliding surface on time to ensure the normal operation of the machine. When injecting oil into the surface of the guide rail, use the oil gun to directly spray the mandrel on the plane of the guide rail and the curved ring to ensure that the front part can be lubricated, and it is necessary to monitor the slip surface for any scratches, fluffs, cracks, etc. phenomenon.
         Second, the composite bearing bush of the machine's secondary and tertiary shafts is filled with lubricating oil through four glass oil cups. When the machine is moving, the oil cup is filled with oil and the switch on the oil cup is opened. position. When the machine is stopped, the oil cup switch can be turned off.
         Third, the lubricating oil of the connecting rod is injected into the lubricating oil through four copper oil cups, and there is an oil filling window on the gear side. After the shutdown, the oil cup is injected with the oil gun.
         Fourth, the lubrication of the university's gears should be regularly injected with oil through the oil injection port marked with “oil” and should be checked regularly.

         Fifth, the machine shaft (including the flywheel side) and the motor moving bearing are sealed with butter seal, and should pay attention to oil change every other year or during machine maintenance.
