When it comes to surface grinding machines, people generally believe that they are machine tools that can only grind surfaces. Understanding the development trend of surface grinder in the world, people's view will change. Nowadays, the development trend of surface grinder is turning forming, step, cutting, rapid jitter, three-dimensional space curve surface grinding. It can be said that the surface grinder is a model with the greatest evolution potential in Dongguan grinder.

Surface grinder plays a very important role in the development of modern company. We have reason to believe that we will make a little progress towards our own pace in the near future, and it is very necessary to maximize our role in the future. Now let's talk about the treatment methods of oil shortage of hand-operated surface grinder?

First, check whether the oil pump of the grinder works normally, which is the main reason why the grinder does not apply oil. 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 it with a new 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 the first, second and third oil valve screws (respectively the upper and lower, left and right, front and rear oil circuit switches of the grinder) from left to right, and 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, the second step should be carried out.

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 the oil change, then check whether the oil outlet of the guide rail is blocked by iron filings. The method is to lift the workbench and blow the air Qiang against the oil outlet. If you feel something blocked inside, you can dredge it with a sharp object.

The surface grinder is composed of many components. In the production process, the rotation direction of the grinding rod should be consistent with the working rotation direction of the grinding wheel shaft, so as to facilitate the self suction oil flow to quickly form an oil wedge through the radial gap during operation, so as to improve the operation performance and avoid deviation of the produced products. Therefore, the development of Dongguan grinding machine is no longer limited to plane grinding, but has been extended to surface grinding. The forming grinding method is popular, which has been highly praised, developed and recognized by large manufacturers and users, and the grinding accuracy is getting higher and higher.
