Ways to keep the accuracy of machine tools
There are many ways to adhere to the accuracy of machine tools, but few people operate in accordance with the specifications, such as the preparation before start-up, precautions during operation, maintenance after start-up processing, regular detection of machine tools, timely replacement of high-quality accessories, appropriate smooth oil, computer system update and maintenance of operating software, and even the temperature and humidity from details to operating environment There are norms to check.
1. After the machine is started, it must be preheated for about 10 minutes before processing. Long time unused machine tool should extend warm-up time.
2. Check whether the oil circuit is unblocked.
3. Before shutting down the machine, place the workbench and saddle in the central position of the machine, and move the three-axis travel to the middle position of each axis travel.
4. Keep the machine dry and clean.
5. Check whether the cooling fan in the electrical cabinet works normally, whether the air duct filter screen is blocked, and clean the dust.
6. Clean and smooth each guide rail surface every day. For machines with active smooth system, check and clean the active smooth system regularly, check the oil volume, increase the smooth oil in time, and check whether the oil pump starts and stops regularly.
7. Pay attention to check whether there is abnormal noise in the oil pump of the hydraulic system of the machine tool, whether the height of the working oil level is appropriate, whether the indication of the pressure gauge is normal, and whether there is leakage in the pipeline and joints.
8. Check the tightness of guide rail insert strip and adjust the clearance.
9. Pay attention to check the main shaft drive belt and adjust the tightness.
10. Pay attention to check the mechanical accuracy of each moving part to reduce the shape and orientation error.
