Maintenance of spindleViews:906times
Good lubrication is able to reduce the working temperature of the bearing and prolong the service life. It should be noted in operation and use as follow: At low speed, grease and oil circulation lubrication should be used; At high speeds, oil mist and oil vapor lubrication are needed. However, when using grease lubrication, the sealing amount of the spindle bearing is usually 10% of the bearing space volume and it must not be filled at will, because too much grease will aggravate the heating of the spindle. For oil circulating lubrication, the spindle weighs that in the operation and use. It is necessary to check the spindle oil tank every day to see whether the oil volume is sufficient, if the oil volume is not enough, the lubricant should be added; At the same time, it is necessary to pay attention to check whether the temperature range of the lubricating oil is appropriate. In order to ensure that the spindle has good lubrication, reduced friction and heat and at the same time take away the heat from the spindle, a circulating lubrication system is usually needed with a hydraulic pump is used to supply oil lubrication and an oil temperature controller is used to control the oil temperature in the oil tank. CNC machine tool spindle means excellent CNC machine tool spindle bearing is lubricated by grease sealing, and can be used for 7~10 years every time grease is added. The new lubrication and cooling method not only reduces the temperature rise of the bearing, but also reduces the temperature difference between the inner and outer rings of the bearing, so as to ensure the minimized thermal deformation of the spindle.
