The daily maintenance of CNC lathe CNC system
The daily maintenance of CNC lathe CNC system release time: 2016 - 08 - 03 clicks: 1, 2570 times to develop and execute strictly the daily maintenance of CNC lathe CNC system of rules and regulations according to the characteristics of different numerical control machine tool, strictly for its daily maintenance of CNC system of rules and regulations, and to strictly implement in the operation and use. 2, should as far as possible open numerical control cupboard and heavy current cabinet door because in the mechanical processing workshop often contain oil mist, dust in the air, once they fall into CNC system on the printed circuit board or electrical components of the easy cause components of the insulation resistance is reduced, and even cause the damage of circuit board or electrical components. So, in the work should be less as far as possible open numerical control cupboard and heavy current cabinet door. 3, timing, clear numerical control lathe numerical control device of the cooling ventilation system, in order to prevent the nc device cooling ventilation system is to prevent overheating nc device overheated important device. Therefore, we should check the CNC every day on the cooling fan operation is normal, once every half a year or quarter check air duct filters are blocking phenomenon, if there should be clear in time. 4, pay attention to the CNC lathe CNC system of the regular maintenance of input/output devices such as the input device of CNC system head cleaning. 5, regular inspection and replacement of dc motor brush early production of nc machine tools, most of the dc servo motor, there is a brush wear problem, therefore for dc servo motor requires periodic inspection and replacement brush dc motor. 6, often monitoring CNC devices use nc lathe CNC system of power grid voltage power grid voltage have strict requirements for work. For example some CNC system allows the grid voltage fluctuations in the range of 85% ~ 110% of rating, otherwise it will cause CNC system can not work normally, even can cause damage of CNC system of the internal electronic components. Therefore always detection power grid voltage, and control on the fixed value & ndash; Within 15% ~ + 10%. 7, regular inspection and replacement of the storage battery in general, numerical control lathe CNC system of some of the CMOS memory storage content maintain when power is on battery power. General use lithium battery or nickel cadmium rechargeable battery. When the battery voltage drops to a certain value, can cause data loss, so the battery voltage should be inspected regularly. When the battery voltage drops to limit or battery voltage alarm, will replace the battery in time. Replacing the battery will make the CNC system under the current status, this will not cause the loss storage parameters. Once the data is missing, after changing the battery, to input parameters. 8 and the maintenance of CNC lathe CNC system for a long time need not when when CNC lathe sit idle for a long time, also want to CNC system maintenance on a regular basis. In the machine tool is not electricity, with a backup battery to power a chip, the data unchanged. Machine tool on the battery when the voltage is too low, usually alarm prompts on the display screen. In the long-term when not in use, should often electricity to check to see if there is alarm prompt, and replace the backup battery in time. Often electricity can prevent electrical components be affected with damp be affected with damp be affected with damp be affected with damp or printed circuit board is short circuit or open circuit and other long-term unused machine, electricity at least twice a week or more. Particular way is: first of all, should be regularly to the CNC system of electricity, under the condition of the machine tool lock motionless, let the machine run empty. Secondly, plum rains season in the air humidity is bigger, every day should be to the CNC system electricity, so that can use electrical components itself fever to the CNC out incase of moisture, to ensure the stable and reliable performance of electrical components. Production practice has proved that if long-term unused numerical control lathe, had often was turned on rainy days are prone to failure. In addition, for the dc servo motor of the nc machine tools, idle for more than six months, if not, you should remove the motor brush, to avoid due to chemical corrosion effect on the surface of the commutator corrosion, to ensure that the reversing performance. Already 9, spare the maintenance of printed circuit board for the purchase of spare printed circuit board shall periodically loaded on the CNC devices operate for a period of time, in case of damage. 10, the processing of numerical control lathe CNC failure occurs once the CNC system fails, the operator should adopt measures to stop, stop the system, and protect the good scene. And assist maintenance personnel ready to the early stage of the maintenance work.
