Luban CNC system host malfunction repair solved within 1 hour

It can process various conductive materials that are difficult to process by general cutting methods, such as high hardness, high brittleness, high toughness, high heat sensitivity metals or semiconductor materials. As an important supplement to mechanical processing, electrical discharge machining has opened up a new path for the trial production of new products, the manufacturing of precision micro parts and molds, such as the convex and concave molds of stamping molds.

The wire consumption of mid line cutting is very important, and the size of wire consumption affects the length of continuous cutting. Therefore, the high cutting efficiency and normal processing efficiency of mid line cutting are two different concepts. The normal processing efficiency of wire cutting is worth referring to. Here, some manufacturers will fill in some exaggerated values in the machine tool information to increase sales.

What is the reason for this? Firstly, we need to consider whether the motor is out of step or out of phase. During wire cutting, out of step or out of phase can easily cause the motor to heat up or even catch fire. So, how can we solve this problem? First, we use a multimeter to measure whether the internal winding of the wire cutting motor is damaged. If it is an electrical blockage, check whether the resistance between the windings is consistent.

Reason for emergency stop alarm fault in CNC system
1. Electrical circuit issues: An open circuit in the emergency stop circuit, a damaged limit switch, or a damaged emergency stop button can all cause an emergency stop alarm. For example, if the emergency stop button is pressed but not turned, or if the limit switch is not flexible due to poor working environment (such as adhesion of small iron chips or erosion by cutting fluid), the contact cannot bounce back to its original state after being pressed.
2. System parameter setting error: Unreasonable or incorrect system parameter settings may cause system signals to not be input and output normally, or reset conditions to not be met, resulting in emergency stop faults.
3. Reset condition not met: The information required for system reset specified in the PLC does not meet the requirements, such as servo power supply, spindle drive not ready, etc.
4. External interference or malfunction: Unstable voltage may cause the driver or frequency converter to sound an alarm, leading to an emergency stop alarm in the system. In addition, spindle unit alarms or spindle driver errors may also cause the system to stop urgently.

Maintaining high precision under high water pressure and precision machining, ⑤ inputting the material, thickness, and processing method of the workpiece, automatically displaying the optimal processing conditions, ⑥ easy to operate and can be set multiple times, ⑦ the wire cutting machine has a sitting memory function, which can automatically record data and sitting when power is turned off, and can quickly process after power is restored, ⑧ the controller interface is simple and easy to learn.

Calculate the relative humidity percentage using the following equation. Among them, Pa=actual pressure Ps=saturation pressure relative humidity depends on temperature. At RH, the actual pressure of water vapor is equal to the saturation pressure. The temperature at which this exists is called dew point. Any cooling below the dew point will cause water condensation. If the atmosphere remains stable at a constant humidity during the day, the temperature drop at night may be lower than the dew point, leading to steam condensation. The condensed steam produces a phenomenon commonly known as dew. A key fact to note is that sensors only need to obtain one measurement value, namely humidity, RH, or dew point, as the other two can be calculated using ambient temperature, charts, or equations. Measuring humidity is not an easy task. Many instruments have poor accuracy, narrow bandwidth, pollution issues, and lag. Some instruments are large, clumsy, and expensive equipment. What makes the problem even more complex is that there are few high-precision devices for humidity generation and measurement used for sensor calibration. The following discusses different humidity sensing methods.

Maintenance method for emergency stop alarm fault of CNC system
1. Check the emergency stop button and circuit: Check if the emergency stop button is pressed but not turned. If the button is damaged or stuck, it needs to be replaced or repaired. Use a multimeter to check if the emergency stop circuit is open, check if the circuit connections are loose or broken, reconnect or replace damaged circuits.
2. Check the limit switch: Check whether the limit switches of each axis are damaged or have poor contact. If there are iron chips adhering to the limit switches or cutting fluid erosion, clean them and test their function. If necessary, replace the switches with new ones.
3. Check the power supply and driver: Check if the power supply voltage is stable and install voltage stabilizing equipment. Check if there are any alarm messages on the drive. If so, troubleshoot according to the alarm code, such as checking the power supply and parameter settings of the drive.
4. Check the PLC program and reset conditions: Check the relevant logic conditions through the PLC program to confirm whether the emergency stop was caused by a program error. Check whether the required information for system reset specified in the PLC is met, such as whether the servo power supply and spindle drive are ready.
