CNC cutting machine equipment is an advanced processing equipment with high degree of automation and complex structure. It is the key and key equipment of the enterprise. To play the high efficiency of CNC cutting machine equipment, it is necessary to operate correctly and carefully maintain the equipment utilization. Correct operation can prevent abnormal wear of CNC cutting machine and avoid sudden failure. Doing routine maintenance can keep the equipment in good technical state, delay the deterioration process, and discover and eliminate hidden troubles in time to ensure safe operation.
First, the maintenance of CNC cutting machine control system CNC cutting machine control system is the only interface to provide human-computer interaction, but also the most direct window for operators to understand and judge the use of equipment, the maintenance work of CNC cutting machine control system should be used as The focus of routine maintenance of the equipment. Its related points include the following aspects:
1. Strictly observe the operating procedures and daily maintenance system. 2. The doors of the CNC cabinet and the power cabinet should be opened as little as possible. In the air of the machine shop, oil mist, dust and even metal powder will generally be present once they fall within the CNC system. On a circuit board or an electronic device, it is easy to cause a drop in insulation resistance between components, and even cause damage to components and circuit boards. In order to make the CNC system overload and work for a long time in the summer, some users take the door of the CNC cabinet to dissipate heat. This is an extremely undesirable method, which will eventually lead to accelerated damage of the CNC system.
3. Regularly clean the cooling and ventilation system of the CNC cabinet. Check that the cooling fans on the CNC cabinet are working properly. Check the air duct filter for blockage every six months or quarterly. If the dust on the filter net accumulates too much and is not cleaned up in time, the temperature inside the CNC cabinet will be too high.
4. Periodic maintenance of the input/output devices of the CNC system Most of the CNC machine tools produced before the 1980s are equipped with photoelectric tape readers. If the band is partially contaminated, it will cause errors in reading information. To this end, the optical reader must be maintained as required.
5. DC motor "target=_blank> periodic inspection of the electromechanical brush and replacement of the DC motor" target=_blank>The transitional wear of the electromechanical brush will affect the performance of the motor and even cause damage to the motor. To this end, the motor power "target=_blank> electromechanical brush should be regularly inspected and replaced. CNC lathes, CNC milling machines, machining centers, etc. should be inspected once a year.
6. Regular replacement of storage batteries In general, the CMOSRAM storage device is equipped with a rechargeable battery maintenance circuit in the CNC system to ensure that the contents of the memory can be maintained while the system is not powered. Under normal circumstances, even if it has not expired, it should be replaced once a year to ensure the system works properly. The replacement of the battery should be carried out under the power supply state of the CNC system to prevent loss of information in the RAM during replacement.
7. Maintenance of the standby circuit board When the spare printed circuit board is not used for a long time, it should be installed in the numerical control system for a period of time to prevent damage.
Second, CNC cutting machine mechanical hardware maintenance If the CNC cutting machine control system provides clear instructions for the operation of the equipment, then the mechanical hardware is the muscle to effectively complete the above instructions. The maintenance work can learn from the hardware maintenance principles of other large CNC machine tools to a certain extent. Below we will mainly focus on the maintenance requirements of some key components of the CNC cutting machine.
1. Maintenance of the main drive chain Regularly adjust the tightness of the spindle drive belt to prevent the phenomenon of throwing due to belt slip; check the constant temperature fuel tank of the spindle lubrication, adjust the temperature range, replenish the oil in time, and clean the filter; After the clamping device is used for a long time, a gap will be generated, which will affect the clamping of the tool, and the displacement of the piston of the hydraulic cylinder needs to be adjusted in time.
2. The maintenance of the ball screw thread pair regularly checks and adjusts the axial clearance of the screw thread pair to ensure the reverse transmission accuracy and axial rigidity. Regularly check whether the connection between the lead screw and the bed is loose; the screw guard has Damage should be replaced in time to prevent dust or chips from entering.
3. Maintenance of torch and robot It is strictly forbidden to load overweight and long torch into CNC cutting machine to avoid collision of gun or torch with workpiece and fixture during machining of torch; often check the return position of torch Is it correct, check whether the machine tool spindle returning cutting position is in place, and adjust it in time; when starting, the torch and the robot should be run empty to check whether the work of each part is normal, especially whether the stroke switch and solenoid valve can operate normally. Check if the torch is securely locked on the robot and find it should be handled in time.
4. Hydraulic and pneumatic system maintenance Regularly clean or replace the filter or filter screen of each lubrication, hydraulic and pneumatic system; regularly check the hydraulic system for oil quality and replace the hydraulic oil; regularly filter the air filter for the pneumatic system. Release water
5. Maintenance of machine tool accuracy Regularly check and correct machine level and mechanical accuracy. There are two types of mechanical accuracy correction methods: soft and hard. The soft method is mainly through system parameter compensation, such as screw backlash compensation, fixed positioning compensation of each coordinate positioning, machine tool reference point position correction, etc.; hard method is generally carried out during machine overhaul, such as rail scraping, ball rolling The screw nut pair is pre-tightened to adjust the backlash and the like.
Third, the CNC cutting machine related issues Supplement We have arranged the maintenance points of the CNC cutting machine control system and the main hardware, as a large CNC machine tool, high-intensity processing and relatively harsh factory environment, for CNC cutting machine There are many possibilities for possible failure problems. In the after-sales service records of hundreds of end users in recent years, Jiabei Technology has listed the related accessories in daily maintenance for some common fault problems. The issues to be noted in maintenance are summarized as follows:
1. The environment in which the numerical control equipment is used is to improve the service life of the numerical control equipment. It is generally required to avoid direct sunlight and other heat radiation, and to avoid places that are too humid, excessive dust or corrosive gases. Corrosive gases tend to cause corrosion and deterioration of electronic components, resulting in poor contact or short-circuit between components, affecting the normal operation of the device. Precision CNC equipment should be kept away from equipment with high vibration, such as punching machines and forging equipment.
2. Power requirements In order to avoid the influence of large fluctuations of power supply (greater than ±10%) and possible transient interference signals, CNC equipment is usually powered by dedicated lines (such as separate from the low-voltage distribution room for CNC machine tools) or additional voltage regulators. Devices, etc., can reduce the impact of power quality and electrical interference.
3. Operating procedures The operating procedures are one of the important measures to ensure the safe operation of CNC cutting machines. Operators must operate according to the operating procedures. When the machine tool fails, the operator should pay attention to retaining the site, and tell the maintenance personnel truthfully before and after the fault, in order to facilitate analysis and diagnosis of the cause of the fault, and eliminate it in time.
In addition, CNC cutting machine tools should not be used for long-term storage. After purchasing CNC cutting machine tools, they should be fully utilized, especially in the first year of operation, so that the vulnerable parts that are easy to fail are exposed as early as possible, and can be eliminated during the warranty period. When there is no processing task, the CNC cutting machine should be energized regularly. It is best to energize 1-2 times a week, each time running for about 1 hour, to reduce the humidity inside the machine by using the heat generated by the machine itself, so that the electronic components It will not be affected by dampness, and it can also detect the occurrence of battery alarm in time to prevent the loss of system software and parameters.
