Common Inspection Method for Failure of CNC Feeder

When the CNC machine alarm, maintenance personnel in no hurry to deal with, and should be observed and tested to find the correct fault location, commonly used diagnostic methods are generally under the punch manufacturers:

1, intuitive method

Sensory organs, note CNC feeder fault phenomena, such as failure without sparks, lights, abnormal noise, the smell of abnormal heating and anxiety charred. Careful observation of the surface condition of each printed circuit board, there may be failures, no signs of burning and damage, in order to further narrow the scope of inspection, which is the most basic and most common method.

2, self-diagnostic function system

Can rely on the numerical control system to carry on the fast processing to the data, to multipath, the fast signal gathering and the processing, through the diagnosis procedure logic analysis and the judgment, judges whether has the system breakdown, carries on the fault localization promptly. Self – diagnosis Function of Modern Digital Control System

3, data and status checks

The self-diagnosis of CNC system can not only display the fault alarm information on the display, but also check the parameters and status information, common data and status check interface in the form of “diagnosis address” and “diagnosis data”.

4, the alarm indicator shows fault

In addition to the self-diagnostic function and status display “software” alarm and many “hardware” alarm indicators, they are distributed in the power supply, servo drive, and input and output devices, according to the alarm light can determine the cause of the malfunction.

Under normal circumstances, the full investigation of the fault site, to understand the cause of the malfunction, to correct the maintenance of CNC machine tools to solve the problem of failure.

Three – dimensional CNC drilling machine for power requirements

The rapid development of high-speed processing technology, three-dimensional CNC drilling machine CNC system part of the operating data, set the data and processing procedures are generally stored in the RAM memory, the system power, the backup battery or lithium battery to maintain. , Three-dimensional CNC drilling machine downtime is relatively long, plug the power supply or memory may cause data loss, the system can not run.
At the same time, because the three-dimensional numerical control drilling machine uses the three-phase alternating current 380V power source, the security is also the important link in the preliminary work of the three-dimensional numerical control drilling machine installation. For the above reason, the following three-
First, the grid voltage fluctuations should be controlled between +10% ~ -15%, while China’s large power fluctuations, poor quality, but also hidden such as high-frequency pulse of this type of interference, coupled with human factors (such as Power outages, etc.) during peak hours, such as during the day or before work hours and nights, often more tolerance, or even up to ± 20% .The machine accessory alarm and can not work properly, and three-dimensional CNC drilling machine power system damage, and even lead to the loss of the parameters of the data, etc. This phenomenon in the CNC machining centers or turning centers and other machine tools have occurred, and the frequency of occurrence should be taken seriously.
If it is necessary to supply other parts of the electrical equipment (such as electronic circuits, electromagnetic clutches) from other sources, it is advisable that they be taken from, as far as possible, from the devices that form part of the mechanical electrical equipment (Such as transformers, transducers, etc.) For large complex machinery, including many working together in a coordinated manner and occupying a larger space, it may be necessary to have more than one power source, as determined by the configuration of the field power supply.
The handle of the power cut-off switch should be easily accessible and should be installed between 0.6M and 1.9M above the easy-to-operate position. The upper limit is recommended to be 1.7M, so that the power supply can be cut off rapidly in an emergency situation to reduce losses and casualties.
Three, three-dimensional numerical control drilling machine For the compressed air supply system requirements, three-dimensional numerical control drilling machine generally use a lot of pneumatic components, so the plant should access clean, dry compressed air supply system network, its flow and pressure should meet the requirements. The air should be installed far away from the CNC machine tools.According to the layout of the plant, the size of gas consumption, should be considered to the compressed air supply system network installation of frozen air in the coal machine, air filters, gas tank, safety valve and other equipment.
Three-dimensional CNC drilling machine for the work environment requirements Precision CNC equipment generally have the requirements of constant temperature environment, only in the constant temperature conditions, in order to ensure accuracy and machine tool.
