            I believe that for most users who use the surface grinder, this is not only a common problem, but also a headache. When you find that the handle of the workbench is heavy, and when you find that the oil quantity of the oil mirror above the grinder is lower than the red oil mark, it will remind you that the surface grinder is faulty, the lubrication system of the grinder is faulty, and there is no oil supply. A grinder cannot be without oil for a day, just as a man cannot be without water for a day? In this case, please don't worry. I'll teach you a few quick checks to gradually eliminate the causes and find out the methods of faults, which may help you eliminate the diseases of Medicine:

            First, check whether the oil pump of the grinder works normally, which is the main reason for the non oiling of the grinder. First, open the back cover of the oil groove on the back of the surface grinder, and directly touch the electromagnetic oil pump to see if it vibrates. If it does not vibrate, it indicates that the oil pump does not work. Remove the oil pump for inspection or replace the oil pump. If it vibrates, it means that the oil pump is still working; Then check whether the oil pump works normally and whether there is oil in the inlet and outlet oil pipes connected with the oil pump. If there is no oil, investigate the oil separator (also known as oil valve) under the oil saving pump. Use a slotted screwdriver to adjust one, two and three oil valve screws (respectively up and down, left and right, front and rear oil circuit switches of the grinder) from left to right. Increase the oil volume counterclockwise. The fourth screw is to adjust the oil pressure, The first three adjustment methods are opposite. Increase the oil pressure clockwise. If there is still no oil supply through adjustment, it may be the following reasons: first, the pressure of the oil pump is not enough for a long time, so it should be removed for inspection or replaced. If the pressure and operation of the oil pump are normal and still do not apply oil, proceed to the second step:

            The second step is to check the oil circuit of the grinder. The so-called oil circuit is the lubrication system. The production first depends on the luster of the lubricating oil. If it is transparent and clear, there is no need to replace it. If it is turbid, black, dark and viscous, it is necessary to replace the new oil immediately. Because the oil is too dirty and sticky, once it enters the guide rail, the oil will not wash away the debris of the guide rail, which will aggravate the feel of the workbench and affect the accuracy of the guide rail. The most important thing is too sticky and dirty, The small power of the oil pump will not pump up, resulting in the idling of the oil pump and burning out, resulting in the paralysis of the whole lubrication system. In addition, pay attention to the selection of oil change. Precision surface grinder has strict requirements for guide rail oil. Generally, it is required to use authentic Mobil 1405 guide rail oil, or isso32# guide rail oil can be used to replace mobil oil, because the concentration of these two oils is not high, It is very clear and greasy, easy to move, and the workbench feels light when used. If the grinder is still not oiled after oil change, then check whether the oil outlet of the guide rail is blocked by iron filings. The method is to lift the worktable and blow against the oil outlet with an empty Qi. If you feel something blocked inside, you can dredge it with a sharp object.

            To sum up, if you want the equipment to work normally, it is still inseparable from daily maintenance and maintenance. For example, if we want to maintain a healthy body, we should not only pay attention to food and daily life, Bao fitness, but also often have a health examination.
