What details should be paid attention to when diagnosing and troubleshooting the cutting machine of Manhart (Guangdong) CNC Machine Tool Co., Ltd?

**Details to pay attention to in the diagnosis and troubleshooting of cutting machine faults**
As a high-precision processing equipment, cutting machines may encounter various malfunctions during use. In order to diagnose and eliminate these faults in a timely manner and ensure the normal operation of the cutting machine, operators and maintenance personnel need to pay attention to the following details:
###1 Safety device inspection
*Ensure that safety devices (such as protective covers, emergency stop buttons, etc.) are intact and functioning properly.
*Before troubleshooting, make sure to turn off the cutting machine and disconnect the power to avoid accidents.
###2 Electrical component inspection
*Check if the electrical connections are tight and if there are any loose or burnt cables.
*Use a multimeter to check if the voltage and current of electrical components such as motors and sensors are normal.
###3 Cutting quality inspection
*Observe whether the cutting surface is flat and whether there are burrs or cracks.
*Check if the cutting size is accurate and meets the process requirements.
###4 Abnormal sound and vibration
*Pay attention to whether the cutting machine emits abnormal sounds or vibrations during operation.
*For abnormal sounds and vibrations, the machine should be stopped for inspection in a timely manner to prevent the fault from expanding.
###5 Abnormal heat check
*Regularly check the temperature of key components such as motors and bearings.
*If abnormal heat is found, the machine should be stopped for inspection in a timely manner to eliminate reasons such as poor heat dissipation or overload.
###6 Circuit troubleshooting
*Use tools such as an oscilloscope and multimeter to check if the circuit signal is normal.
*For circuit faults, they should be gradually investigated, from simple to complex, to avoid blind replacement of components.
###7 Mechanical troubleshooting
*Check if the mechanical components such as the transmission system and bearings are worn or loose.
*For mechanical failures, analysis should be conducted based on the equipment structure and working principle to identify the cause of the failure and take corresponding measures.
###8 Laser cutting issues
*Check if the cooling system of the laser is working properly to avoid overheating of the laser.
*Regularly check whether the lens and reflector of the laser cutting head are clean and undamaged.
*If the cutting quality decreases, it may be due to insufficient laser power or improper beam adjustment, and relevant components need to be adjusted or replaced.
When conducting fault diagnosis and troubleshooting, the following principles should also be followed:
*First simple, then complex: Start with easily identifiable areas and gradually delve deeper.
*First appearance, then interior: Check external components and connections before considering internal components.
*Power supply before load: Check the power supply and electrical components first, and then check the mechanical load part.
In summary, for the diagnosis and troubleshooting of cutting machines, meticulous and comprehensive consideration is needed to ensure accurate diagnosis and appropriate measures, in order to ensure the normal operation and production efficiency of the cutting machine.
