At noon, Yang Jun drove out of the factory.

When he came back, there was an extra jar on the car.

He drove the car directly to the downstairs of the hospital next door, and then called someone to take the jar to Yi Qiushui's office.

In the past few days, he had to avoid Ding Qiunan to avoid seeing her resentful eyes.

The transfer order from above has been issued, and there are other candidates for the two vice-presidents, who will take office in a few days.

He won't go to Yi Qiushui's place to eat in the past few days. After the dust has settled and Ding Qiunan has lost his thoughts, he will go there again.

Of course, when he went back, he didn't forget to stop by the security department and scold Wang Erwa like crazy.

When he was about to get off work in the afternoon, Han Shengli sent someone to call him and told him that the lathe had been modified and asked him to come over and take a look.

When Yang Jun heard this, he immediately put down all the work in his hands and went to the workshop.

This is a matter related to his political performance and must be treated with caution.

When I came to the workshop, I saw a group of people surrounding the machine tool.

They all had smiles on their faces and seemed to have tested the machine.

“How can it be used?”

Yang Jun raised his hand to stop those who wanted to say hello to him and asked directly.

"It works, we've been running it for ten minutes."

Han Shengli looked excited, patted the modified machine tool and said, "We tested it just now, and it was much faster, much better than originally expected."

Yang Jun looked at the modified part with his hands behind his back.

There are some more gears between the lathe gearbox and the feed box.

These gears are temporarily made by eighth-level workers in the factory. They have beautiful appearance, suitable size, and the fit between the various parts is very good.

Next, Yang Jun looked at another improvement, which was the addition of two low-power motors on both sides of the lathe.

Although, Yang Jun didn't know what the motor was used for, it must have something to do with its operating efficiency.

"Director, this is a servo motor."

Han Shengli saw that Yang Jun kept staring at the two motors, so he explained.

"servo motor"

Yang Jun was startled when he heard this and asked: "We have this thing in the factory."

He remembered that the earliest servo motor technology only appeared in the 1980s, but he did not expect that such a thing would exist now.

"Yes, it was imported from abroad before, but it was too expensive. Later we started to develop it ourselves. This motor was developed by the Third Research Institute." Han Shengli explained.

"Is this motor expensive?" Yang Jun asked.

Han Shengli was startled for a moment, his face looked a little ugly,

"Not only is it expensive, it's extremely expensive. A motor costs more than 300 yuan."

"More than three hundred yuan"

When Yang Jun heard this, he was immediately startled.

Even in later generations, you could buy a good motor for 300 yuan, but in this era, asking for more than 300 yuan is no different from robbing it.

However, it’s no wonder that the price is so high. The new product has not yet been mass-produced, so the price must be high.

However, Yang Jun then thought, if this transformation and upgrade can be successful, it will be worth spending this small amount of money.

"Okay, don't worry about the motor for now, get ready to start it up."

Yang Jun waved his hand and signaled them to start testing.

"Okay, director."

Han Shengli responded, then looked back at the fifty-year-old employee next to him and said,

"Master Zhao, come and turn on the phone."

Leave professional things to professionals.

Even though Han Shengli is an engineer, when it comes to lathe skills, any third-level worker in the factory is better than him.

The Master Zhao in front of him is the only eighth-level lathe in the factory. Yang Jun knows him. His name is Zhao Wencheng. When he went to the arsenal for inspection before, it was this Zhao Wencheng who produced qualified pipe fittings.

When Zhao Wencheng heard this, he didn't say anything and just nodded.

He rolled up his sleeves, spit in his palms, rubbed his hands together a few times, and then started to operate the machine tool.

Everyone retreated far away, staring at Zhao Wencheng.

Zhao Wencheng touched the power switch and pressed it hard.

"Buzz!"

The moment the power is turned on, the spindle begins to rotate at high speed.

When the main shaft rotates, I have seen the bridge gear, which drives the polished rod next to it. The worm on the polished rod drives the turbine and the longitudinal cams on the two turbines... Using line switches and electromagnets, the semi-finished column head components placed on the angle iron are quickly

The spring chuck in front of the spindle is fixed, and then the longitudinal knife is fed to the specified position.

The modified courtyard and action path may sound a bit complicated, but the actual operation is completed in an instant.

"Now!"

A sharp metal cutting sound sounded.

Dark blue iron filings peeled off in circles, and a rough-turned pig's head was quickly finished cutting.

"Click!"

The lever pushes the transverse turning tool forward, the processed column head part is cut off, the spring chuck is released, and the waste material also rolls down into the iron box located in the spring chuck.

"Buzz!"

After a sound, the lathe stopped.

Zhao Wencheng turned off the power, picked up the workpiece in the iron box with pliers and handed it to Han Shengli and said,

"Han Gong, please measure the accuracy."

Han Shengli took the pliers and placed them on the tool box next to him.

Then take out the vernier caliper. You don't need a micrometer for this kind of rough turning workpiece.

After careful measurement, Han Shengli showed a smile on his face.

He turned back to Yang Jun and said: "Director, the size is qualified."

"Then...this is considered a success." Yang Jun asked.

"It was successful, very successful."

Han Shengli looked sure, and then said: "It used to take at least three minutes to complete a workpiece like a car, but now it only takes tens of seconds to complete. This efficiency improvement is not even a little bit."

When Yang Jun heard this, he was shocked.

He tried hard to control the joy in his heart, and then said with his hands behind his back: "The quality is okay, but we still have to see how the efficiency is."

"Make a few more cars and see what the pass rate is."

Although Yang Jun doesn't understand technology, he still understands the most basic things.

The speed has increased, but a series of problems will also arise.

In the production of workpieces, we must not only pursue efficiency, but also pursue quality.

If the pass rate of the workpieces produced is very low, it is useless no matter how fast the speed is.

Seeing that Yang Jun affirmed his work, the excitement on Han Shengli's face never dissipated.

This chapter is not over yet. Please click on the next page to continue reading! After looking at his watch, he said: "Director, there is still half an hour until get off work is over. Why not use this time to see how much can be processed?"

"Um."

Yang Jun waved his hand and said: "I will do as you say."

After receiving the instruction, Han Shengli signaled Zhao Wencheng to continue the test.

Later, several employees helped put all the materials on the angle iron rack for feeding materials.

Several employees patted Zhao Wencheng on the shoulder and said: "Old Zhao, come on, it's up to you."

"Master Zhao, come on."

Everyone is very excited. They hope that the machine tool can be successfully modified more than anyone else. After all, this is the result of their whole day's work.

Then, the machine starts again and starts a new round of processing procedures.
