In a busy aluminum alloy forging workshop, Master Li is an experienced operator. He works with all kinds of machinery every day and knows the importance of safety. Recently, the workshop introduced a new type of servo electric screw press, heard that it has four safety protection measures, Master Li is full of curiosity.

One day, Master Li was operating a press to press aluminum forgings. Suddenly, he received an urgent call that required him to immediately go to another workshop to deal with an emergency. Master Li left the press in a hurry, forgetting to turn off the power to the equipment.

Just then, a new employee, Xiao Zhang, entered the workshop. He was curious about everything in the workshop, and came looking around. Before he knew it, he walked over to the servo electric screw press and curiously reached out to touch the slider.

At this time, the servo motor realizes the zero speed function. It responds quickly, stopping the slider in an instant. Xiao Zhang was startled and quickly withdrew his hand. He looked at the machine doubtfully, not knowing what was going on.

Immediately after, the mechanical braking device is quickly activated, providing additional braking force to the slider, ensuring that it stays firmly in place. This scene was just passing by the workshop supervisor saw, he came over to ask about the situation. With a blank look on her face, Xiao Zhang explained that she had only touched it curiously.

The workshop supervisor breathed a sigh of relief, knowing the importance of the four-fold safety protection of this servo electric screw press. He patiently explained the working principle and safe operation procedures of the equipment to Xiao Zhang, and reminded him to be careful in the future and not to touch the machine at will.

Xiao Zhang nodded to show that he understood. Just then, the lights in the workshop suddenly flashed, and the power supply was abnormal. However, the third safety protection of the servo electric screw press immediately comes into play. The slider stops moving for an instant, as if frozen in place.

Both Xiao Zhang and the workshop supervisor watched the scene in shock, filled with respect and gratitude. They know that without the four-fold safety protections of this machine, today's accident could have had serious consequences.

The last line of defense is the infrared security grating. It forms an invisible safety light screen in the workshop, guarding the safety of production personnel. When Xiao Zhang strayed into a dangerous area, the infrared safety grating immediately issued a warning and stopped the operation of the device. This made Xiao Zhang completely understand the magic of this machine.

The workshop supervisor patted Xiao Zhang on the shoulder and encouraged him not to be discouraged, to carefully study and follow the workshop's safe operating procedures. Xiao Zhang nodded gratefully and said that he would keep this lesson in mind and strive to become a qualified operator.

Since then, whenever Master Li and other employees talk about the accident, they will fondly recall how the four safety measures of the servo electric screw press saved Xiao Zhang's life. They have said that they should cherish and pay more attention to the safety production work of the workshop, and jointly contribute to the prosperity and development of the company.
