In the event that CNC machine tools at manufacturing facilities that produce die cast - Lindawu - 11-01-2023

The diagnosis and repair of issues involving computer numerical control (CNC) equipment,the occurrence of the phenomenon known as case failure, which includes the following:As soon as the power is turned on for the machine tool, the cathode ray tube (CRT) does not display either grayscale or a picture on its screen.The manufacturer has a significant amount of control over the power supply of the CRT unit, both in terms of the components that it contains and the voltage that it uses.This is especially true when thinking about the make-up of the supply.The power supply for a 9-inch monochrome CRT is typically +24 volts DC, while the power supply for a 14-inch color CRT is typically 200 volts AC.

Both monitors use cathode ray tubes.As a consequence of this, prior to carrying out this step, you ought to first carry out some research in order to acquire information regarding the particular conditions of the apparatus.A cathode ray tube, or CRT for short, is a type of electronic component that is made up of several distinct units, such as a display unit, a regulator zinc die castings unit, and other units. It is also sometimes referred to by its acronym, CRT.After connecting the computer to the VIDEO signal coming from the MMC circuit board of the CNC system, we discovered that the computer was unable to recognize the signal. This was the case despite the fact that the computer was properly connected to the signal.After we had successfully connected the computer to the signal, we made the discovery that this was the case.The lack of the signal is also reflected in the monitor's display of the situation.Because of this, we have no choice but to come to the conclusion that the board of directors for the MMC is the source of the issue. This is the only reasonable explanation.When dealing with any issues that involve circuit boards, we need to always exercise the utmost caution. This is especially important when working with electrical current.In the event that there is an issue with the circuit board in the CNC system, it is not difficult at all to lose data.

Notable in particular is the MMC board, which, in the same way that a computer that is used on its own has its own memory and hard drive, operates in a manner that is very similar to that of a computer that is used on its own.status, because even a slight change in it can result in the loss of data or the burning of the cable connector that is used in the VCE series CNC single column vertical turning machining center. This is the case despite the fact that even a slight change in it can have this effect.It will be possible to find a solution to the issue once the cause of the underlying problem has been identified and the most effective method of treatment has been proposed.A breakdown of the problems that are most frequently experienced with computer numerical control (CNC) equipment.

1) The means by which electricity is supplied to the drive:The feed drive system is comprised of its two component subsystems, which are referred to as the direct current (DC) feed drive and the alternating current (AC) feed drive, respectively.It is possible, more or less, to categorize the mistakes that take place into one of three distinct categories.There are two options available here: the first one is to use the software diagnostic program to display alarm information on the CRT; the second option is to use the hardware on the speed control unit (LED indication, blown fuse, etc.). The first option is the preferred one.Utilizing the software diagnostic program is the first option available to you.On the computer monitor (or CRT), the information pertaining to the alarm can be displayed with the assistance of the software diagnostic program.The activation of an error alarm that is linked to the servo feed system is the first outcome that could occur as a result of this situation.The malfunctioning of the system that controls the vehicle's speed is the most typical reason for these alarms, accounting for the vast majority of incidents..

3) Alarms that are generated by the hardware, such as alarm lights on the speed control unit and alarms such as a blown fuse and various switches being tripped. 4) Alarms that are generated by the software. 4) Alarms generated by the software itself. One can make a distinction, speaking on a more general level, between the following categories of circumstances:1 Exercise extreme caution, the voltage is at an all-time high. The megometer is the instrument of choice when it comes to determining the level of insulation capacity of the motor. Typically, the underlying cause of this type of alarm is damage to the power drive component of the speed control unit, more specifically the thyristor module or the transistor module. A faulty sensor is another potential source of activation for an alarm of this type. If it is less than ten cents, then this indicates that there is a problem with the module in some way.

3 An alert for the voltage that is currently too low. Warning signal for overload of 4A current. It is possible to make adjustments to the value that is being utilized at the moment. 5 A signal for the speed feedback alarm's indicator light. When there is a problem with the speed or position feedback lines of the servo motor, or when there is a problem with the connector contact, this type of alarm will be triggered the majority of the time. 6Either the circuit breaker has been turned off or the fuse has been burned all the way through to its metal core. One of these two things has happened. If an alarm of this kind is simply an open and obvious illustration of the operation of a protection switch, then the logic that underpins it is extremely simple to grasp. If the transformer gets too hot and the circuit breaker trips, there is a problem that needs to be investigated to figure out what caused the problem in the first place. 8There is a problem because there is no alarm display. This needs to be fixed. In the event that you find yourself in a situation of this nature, you need to give it careful thought before arriving at a conclusion that is informed by the particular circumstances that are in front of you. In other words, you need to avoid making rash decisions.

3. A classification of the malfunctions that manifest themselves in the spindle control unit with the greatest frequency

Both direct current (DC) and alternating current (AC) are viable options for spindle drives, just die casting aluminum as direct current (DC) and alternating current (AC) are viable options for feed control units.

1) The temperature inside the motor has risen to an unacceptable level and could cause damage. The causes of this type of failure include an excessive load, a motor cooling system that is too dirty and, as a result, is unable to cool normally, a cooling fan that is unable to function normally, and poor contact between the motor and the control unit. After some time had passed, the lubricating oil for the transmission was investigated, and it was discovered that the oil had been severely contaminated, which was the primary cause of the overheating. This discovery was made after it had been determined that the oil had been severely contaminated. This was the fundamental issue that needed to be addressed. The impedance on the AC power side is too high, the rectifier bridge of the power supply is damaged, the inverter-enabled transistor module is damaged, and the circuit board of the control unit is faulty. All of these problems stem from the fact that the power supply is faulty. These four aspects are responsible for an overwhelming majority of the problems that lead to this type of failure. Each of these contributing factors can be held individually responsible for the failure.

3) The spindle motor is behaving in a very peculiar manner, as evidenced by the fact that it is producing peculiar noises and vibrating in an unusual manner. If it happens when you are slowing down, the problem most likely lies with the circuit that regulates the regeneration process. If it happens at a rate that is always the same, the first thing you need to do is figure out if the feedback voltage is typical or not. If it is typical, then you can move on to the next step. After that, you must abruptly terminate the command, and while the motor is in the process of stopping, you must pay close attention to the sounds it makes to determine whether or not there are any noises that are out of the ordinary.
