The cutting section, led by Chen Jian, the section leader, has always been at the forefront of the workshop production. Especially the laser, flame, and CNC machine operators, they basically work "5+1" and "white+black". Both laser cutting machines operate non-stop throughout the day. The flame and plasma cutting machines cut thick plates, so the cutting speed is slow. In order to ensure the successful completion of production tasks, the operators overcame their own difficulties and gave up their Sunday rest time to work overtime without complaint. Laser operator Zhang Binghua fell off his bike on his way to work, resulting in a fractured rib. The doctor advised him to rest more and do less physical activity at home, but stubborn he didn't listen to the doctor's advice and only rested for a few days before returning to work.
