In the maintenance of CNC lathes, changing the engine oil is a very important and difficult task. Whether it is the emptying of old oil or the filling of new oil, there are certain requirements fortechnology and experience. For example, how to deal with incomplete emptying of old oil, how much new oil can be added to start the machine, and so on. Today, our CNC lathe manufacturer will explain the method of changing lathe engine oil to you.
Find something to put the engine oil in, put it in one place and don't touch it. Over time, the dirty engine oil will sink to the bottom, and everything on top will be clean. The level of the national standard is still at the APISJ level, so it is natural to cut corners and use inferior materials. If your car has a problem with high oil consumption, using 10w American, Jia, and shell production in Europe would require higher costs to meet this requirement. It is useless to replace 5w-40 with 40 in order to meet the requirements of the United States. According to the old technology conditions, it should be considered.
Mainly carried away by a large amount of metal shavings, the more metal shavings, the more shattered and thin they are, the more oil they carry away every day. To recycle, metal shavings can only be separated using a centrifugal separator. Check in the following order: 1. Check if there is any leakage in the system. 2. Check if the lubrication supply is too large. 3. Check if the viscosity of the oil has decreased. 4. Check if the oil evaporates quickly. Simple solution: Buy an automatic lubrication pump (with oil tank and control circuit), install it on the CNC machine tool, just connect the oil pipe, it can supply oil in a timed and quantitative manner, turn on the power of the machine tool, and it will start working. This is how lubrication is done on typical CNC machine tools. Even more advanced, it is controlled by the CNC system to pump oil, and the machine tool will not supply oil when it is not working. This is okay.
Anti wear hydraulic oil is added to the spindle box of CNC machine tools (N32 and N46 can be added in winter, N46 and N68 can be added in summer). The main function of lubricating oil in the spindle box of CNC machine tools is to lubricate and dissipate heat. Anti wear hydraulic oil products are high-quality and high-performance oils that can be used in applications such as industry and automobiles that require anti-wear lubricants. Anti wear hydraulic oil is specifically designed to withstand high pressure. There is water in the oil tank of the CNC lathe. Let me tell you, water is heavier than oil. Fill the top with oil, suck out the oil on the top, and the bottom with water. Then, suck out the water, put in the oil that has been sucked out, and add some more oil. The oil tank will be empty of water.
The above is the method taught by CNC lathe manufacturers to change lathe oil. We hope that the above explanation can be helpful for everyone when changing oil for CNC lathes in the future.
