After explaining the maintenance principles to Hu Changzheng, Guo Yonghe started to do it.

The result was more conservative than what he told Xiang Lixin before that he could repair the thermal relay in about ten minutes. In fact, it only took him more than a minute to complete the repair of the thermal relay.

Xiang Lixin looked aside and almost poured another quick-acting Jiuxin Pill into his mouth.

Is the thermal relay that was repaired in just over a minute really usable?

He looked at Hu Changzheng nervously, waiting for the results of his instrument test.

Hu Changzheng repeatedly tested the thermal relay three times with instruments. The results proved that Guo Yonghe was right. Although there were only two resistive heating elements, the performance indicators of the thermal relay were completely normal. There was no difference compared to the previous three resistive heating elements.

the difference.

"Report to the factory director that the performance indicators of this thermal relay are completely normal and can be installed and used!"

He reported to Xiang Lixin.

Xiang Lixin's heart hanging in his throat fell back into his stomach. He made a gesture to Hu Changzheng and said: "Then don't waste time, quickly install it on the machine tool and start it up to give it a try!"

"Not yet!"

Hu Changzheng pointed to the equipment technicians who were busy on the side, and said to Xiang Lixin: "We have to wait until they finish processing and installing the servo motor before we can install this thermal relay."

When Xiang Lixin took Guo Yonghe to the side to talk, Hu Changzheng was not idle either. He took it upon himself to remove and reinstall the air-conditioning water shield in the electrical control cabinet that Du Xiangyang had installed upside down.

, and ordered the men in the equipment department to disassemble the servo motor that had been flooded with water, and clean and dry the inside.

Because if the inside of the servo motor is not cleaned and dried, even if a good thermal relay is replaced, the machine tool may still be burned out again after it is started.

However, the internal cleaning and drying of the servo motor is a complicated and meticulous job, so now that Guo Yonghe has repaired the thermal relay, the technicians from the equipment department have not yet completed the internal cleaning and drying of the servo motor.

So Xiang Lixin could only wait patiently.

After about ten minutes, the technicians from the equipment department completed the internal cleaning and drying of the servo motor. Then they assembled the servo motor and installed it into the servo system of the machine tool, which took more than ten minutes.

In fact, the two together took less than half an hour, but it made Xiang Lixin feel that it was extremely long, and he almost burst into tears. After finally seeing that the servo motor was installed, he immediately directed Hu Changzheng to

The thermal relay is installed.

Hu Changzheng naturally understood Xiang Lixin's mood. He did not dare to neglect and quickly installed the thermal relay. Then he carefully checked the connection lines including the servo motor and the thermal relay to prevent mistakes in the rush and missed connections.

connection situation.

After everything was checked and everything was OK, he stood up and made a gesture to Xiang Lixin.

Xiang Lixin was waiting for this gesture, and immediately said to him: "Start!"

So Hu Changzheng pressed the start switch of the Sarem CNC machine tool, and with a steady low sound, the machine tool started.

Xiang Lixin, Hu Changzheng and Fang Yunlei, the director of the metalworking workshop, were all crowded in front of the electrical control cabinet, nervously staring at the control panel of the private server system above, fearing that a fault alarm would appear on it.

As a result, they waited for four or five minutes, and the servo system showed normal, no fault light flashed, and no alarm sounded.

But even so, the three of them still didn't dare to let go of their hearts.

Because some faults will not be displayed when the CNC machine tool is on standby, and will not be displayed until the machine tool starts working.

"Director Fang, please give it a try!"

Xiang Lixin said to Fang Yunlei.

Fang Yunlei said "yes", then pressed the pause switch of the machine tool, took a gear blank that was roughed out in the afternoon and put it into the CNC machine tool, entered the processing program code on the servo system, and then restarted the switch.

Just listen to a "buzz" sound, and as the power is turned on, the spindle of the Sarem CNC machine tool begins to rotate rapidly.

As the main shaft rotates, the kinetic energy is transmitted to the polished rod next to it through the bridge gear, and then transmitted to the worm wheel through the worm connected to the polished rod. The worm wheel drives the longitudinal cam connected to it...

Through a series of complex transmissions, and finally with the help of limit switches and electromagnets, the rough-machined gear blank on the CNC machine tool is pushed to the spring chuck in front of the spindle and firmly fixed.

Then the alloy cutter head responsible for processing was moved to the designated position. As a sharp and harsh metal cutting sound sounded, blue-glow steel chips rolled down one after another. Soon, a delicate gear followed the alloy

The reciprocating cutting of the cutter head reveals the shape.

Finally, as the processing is completed, there is only a "click" sound, the spring chuck automatically releases, and the processed gear falls into the finished iron box directly below the spring chuck.

During the entire process, the machine tool ran completely normally, without any fault lights or alarm sounds.

But that alone is not enough!

Hu Changzheng on the side immediately picked up the vernier caliper and took the finished gear out of the iron box for measurement.

Soon, the entire gear was measured and he said to Xiang Lixin, who was craning his neck to wait for the results: "Director, the accuracy of the gear not only complies with regulations, but also meets the standards of high-quality products!"

Xiang Lixin felt relaxed after hearing this, but Fang Yunlei ordered: "Director Fang, load the materials and keep trying!"

So Fang Yunlei continued to take out the gear blank and put it on the CNC machine tool to continue processing.

One, two, three, he completed the processing of ten gears, and the machine tool did not have any malfunctions. According to Hu Changzheng's on-site inspection, the qualification rate of these ten precision gears reached 100%, and six of them were

The precision of the gears has reached the level of high-quality products.

"Okay, Director Fang, it's okay, stop it!"

At this time, Xiang Lixin finally let out a long breath, telling Fang Yunlei not to continue trying.

The data in front of you is enough to prove that the Sarem CNC machine tool has been perfectly repaired by Guo Yonghe and there are no faults!

At the same time, this also meant that the nearly one-million-dollar order from the Provincial Foreign Trade Company, which had almost flown away before, fell into the hands of the Heavy Machinery Factory again, and the deputy department-level leadership ladder that was almost closed to him was once again

Be open to him…

"Technician Guo, thank you, thank you!"

Xiang Lixin held Guo Yonghe's hand and shook it non-stop, "Thank you for saving our heavy machine factory this time. From now on, no matter whether I, Mr. Xiang, are in the heavy machine factory or not, the heavy machine factory will be your technician Guo's second home."

.

"In the future, if you have any difficulties and need help from our heavy machinery factory, just come over. If anyone dares to say no to you, just tell me. Even if I, Mr. Xiang, leave the heavy machinery factory, I will not be able to help you."

I will definitely come forward to make the decision for you!"
