The correct operation and maintenance of numerical control equipment is one of the key factors for the correct use of numerical control equipment. Correct operation and use can prevent abnormal wear and tear of the machine tool and avoid sudden failures. Doing a good job in daily maintenance can keep the equipment in good technical condition, delay the deterioration process, and discover and eliminate hidden troubles in time to ensure safe operation.
1. The use environment of CNC equipment
In order to improve the service life of CNC equipment, it is generally required to avoid direct sunlight and other heat radiation, and avoid places with too much humidity, too much dust or corrosive gas. The precision numerical control equipment should be far away from the equipment with large vibration, such as punching machine, forging equipment, etc.
2. Good power supply guarantee
In order to avoid the influence of large power fluctuations (greater than ±10%) and possible instantaneous interference signals, the numerical control equipment generally adopts dedicated power supply (for example, it is divided from the low-voltage power distribution room to be used by the numerical control machine tool separately) or the voltage stabilizing device is added. It can reduce the influence of power supply quality and electrical interference.
Three, formulate effective operating procedures
In the use and management of CNC machine tools, a series of practical and effective operating procedures should be formulated. For example, lubrication, maintenance, reasonable use and standardized shift system are the main contents of the use and management of CNC equipment. Formulating and complying with operating regulations is one of the important measures to ensure the safe operation of CNC machine tools. The practice has proved that many failures can be reduced by observing operating procedures.
4. Numerical control equipment is not suitable for long-term storage
After purchasing the CNC machine tools, make full use of them, especially in the first year of use, so that the weak links that are prone to failure can be exposed as soon as possible and can be eliminated during the warranty period. During processing, minimize the opening and closing of the spindle of the CNC machine tool to reduce the wear of clutches, gears, and other components. When there is no processing task, the CNC machine tool should be energized regularly. It is best to power on 1 to 2 times a week, and run dry for about 1 hour each time, so as to use the heat generated by the machine tool to reduce the humidity in the machine and prevent the electronic components from getting damp. At the same time, it can also detect in time whether there is a low battery alarm to prevent the loss of system setting parameters.
5. Maintenance of CNC machine tools
There are many types of CNC machine tools, and all types of CNC machine tools have different characteristics due to their different functions, structures and systems. The maintenance content and rules also have their own characteristics. Specifically, according to the type, model and actual use of the machine tool, and concerning the requirements of the machine tool manual, the necessary regular and graded maintenance system should be formulated and established.
