In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

When checking the operation of each axis of the laser cutting machine tool, apply manual continuous feed to move each axis and check whether the movement direction of the machine part is correct by the display value of the CRT or DPL (digital display). Then check whether the movement distance of each axis matches the movement command. If they do not match, check whether the relevant commands, feedback parameters, and position control loop gains are correct.
Then use manual feed to move the axes at a low speed and make them touch the overtravel switch to check if the overtravel limit is valid or not, and whether the control system will give an alarm when overtravel. Finally, a return to the reference point should also be performed. The reference point of the CNC cutting machine is the program reference position after the machine tool is processed. Therefore, it is necessary to check whether the reference point function and the position of each return reference point are exactly the same.
The power-on operation of the laser cutting machine can be a full-scale power supply for each part, or each part can be powered separately, and then make a total power supply test. It is safer to supply power separately, but it takes longer. After power-on, first observe the alarm failure, and then manually start the components in a manual manner. Check whether the safety device works, whether it can work normally and whether it can achieve the rated working index. In short, according to the machine tool specification data, it roughly checks the main components of the machine automation network, whether the function is normal and complete, so that the machine tool can operate in all aspects.
Then, adjust the bed level of the CNC cutting machine, coarsely adjust the main geometric accuracy of the machine, and then adjust the relative position of the reassembled main moving parts and the host, use the quick-drying cement to fill the anchor bolts of the host and each attachment, and put each Keep the hole level and wait for the cement to dry completely. When the numerical control system and the machine tool are powered on and on-line, although the numerical control system has confirmed that there is no alarm in normal operation, it is necessary to make preparations for pressing the emergency stop button at the same time when the power is turned on, so as to cut off the power at any time.
