Back to the 80s Machinery Factory

Chapter 122 Where is my sweater?

Although Chen Dazhi drove Chen Luyang away like a chick.

But at noon,
Chen Luyang still ran to the forging workshop and supervised his father to close his eyes for a while.

quickly,

With the concerted efforts of many senior technical workers, the cast iron camshaft was quickly produced after several attempts!

"No deformation!"

Yang Xiangyang took out the finished camshaft, carefully observed its shape, and then turned back to report to Chen Dazhi.

However, it is not enough to just look like it is not deformed.

To process the camshaft, it is necessary to ensure that it does not deform during the processing!

"Old Jin! Hurry up and cut it with a knife to see if it will change shape!!!"

Chen Dazhi patted Jin Dakui's shoulder anxiously.

Jin Dakui: "Just look at me!!"

As he spoke, Jin Dakui started turning the prepared camshaft with his hands.

But as I kept whittling,

Jin Dakui is no longer in power.

Chen Dazhi asked anxiously, "Lao Jin, why did you stop?"

Jin Dakui turned around and said, "Old Chen, this material is really good! It really doesn't deform at all!!"

"I can't even chip it, how come it's deformed?!"

……

"What do you mean by not being able to cut it?"

In the Deputy Director's Office,
Yu Anshan looked at Chen Dazhi and Jin Dakui, two eighth-level workers, sitting on the sofa, and asked a question from the bottom of his heart.

Kim Dae-gyu explained:
"Director Yu, we addressed the issue of low camshaft yields raised by the factory by changing the material content and converting the camshaft into cast iron, successfully solving the problem of camshaft deformation."

"But after quenching, the cast iron camshaft has a very high strength and hardness, so it cannot be cut with a knife and must be ground."

Yu Anshan subconsciously said, "Then let's grind!"

Jin Dakui said helplessly: "I have ground it, but our grinder is not good enough..."

The grinder doesn't work?
Yu Anshan asked back, "I remember our grinder, wasn't it a CNC gantry milling machine that we just bought from Qicheng two years ago? This doesn't work???"

Speaking of this CNC gantry milling machine, it was something the provincial machinery factory was quite proud of back then.

At that time, there were no high-speed grinders in China.

The milling machine produced by Qicheng Second Machine Tool Factory is the first CNC gantry milling machine in China.

Not long after it was developed, it was bought back by a machinery factory.

This news had a huge impact at the time and was even reported in the newspapers.

In theory, this milling machine is already the best machine tool in the provincial capital.

This doesn’t work? ?
Kim Dae-gyu explained: "Different materials require different processing."

"Although the milling machines in the factory are functional, they still cannot meet the factory's requirements for improving the yield rate of camshafts, and the qualified rate remains low."

Yu Anshan didn't give up: "Is there no way to solve it?"

Chen Dazhi: "There's really no other way."

If the materials are not good, they can be remade.

But the milling machine didn't work, and they really had no other choice.

Yu Anshan was silent.

The two masters in front of us represent the most sophisticated and mature craftsmanship in the factory.

Since even they said so, it seems there is no room for maneuver.

Although they can make camshafts by hand to meet the current orders for a few small cars.

However, if a car production line is built in the future, it will still be necessary to purchase new usable machine tools!
Silent for a long time,

Yu Anshan said: "I know about this. You guys go back first, I'll find a solution."

……

After sending Chen Dazhi and Jin Dakui away,

Yu Anshan smoked a cigarette in the house and looked out the window with deep eyes.

Then he put out his cigarette and walked out of the office.

At this time, the Purchasing Department on the 4th floor
Song Liaosha was holding a small notebook, her eyes shining as she wrote down the cities where she wanted to book tickets.

Ever since the last time he and Fu Donghu went to the Huahai TV Factory and bought a color TV for the factory.

He became very interested in business trips!

He had always lived in the provincial capital since he was a child and had hardly ever taken a train.

I suddenly squeezed into a train with a large group of people and saw other cities. It really felt like my eyes had been broadened!

Fu Donghu: "Have you written it down?"

Song Liaosha: "I've got it down. It's Fulin Glass Factory in Chudong City. I'll go to the train station to buy a ticket this afternoon."

Last time, Fu Donghu wrote down the addresses and production requirements of many factories at the National Machinery and Heavy Machinery Exhibition.

After consulting with the factory director and deputy factory director,
He roughly identified several directions and objects that needed to be purchased and consulted.

While winter is not here yet, the weather is still good.

He planned to take Song Liaosha to visit all these places.

The two people had just decided on the next place to go when they heard a knock on the door.

then,

Yu Anshan pushed the door open and walked in.

"Director Yu?"

Fu Donghu quickly stood up, with a look of surprise in his eyes.

Song Liaosha also quickly stood up and looked at Yu Anshan with a serious face.

"Sit down and talk, sit down and talk."

Yu Anshan placed his hands in the air, making a downward gesture.

But how could Fu Donghu and Song Liaosha dare to sit down!
The two men stood straight, their eyes looking at Yu Anshan, quietly waiting for their leader's instructions.

Yu Anshan: "I remember your last report saying that a machine tool factory over in Lanhai produced a new machine tool?"

Fu Donghu is smart and has a good memory.

Without even turning the page, he spoke:

"Yes!"

"The Blue Ocean First Machine Tool Factory produced the horizontal CNC machining center."

After a pause,
Fu Donghu said, "I have already reported this to you, Director Wang, and Deputy Director Dong."

"But considering that the factory just bought a CNC gantry milling machine two years ago, this factory and product were not listed in the procurement file."

Fu Donghu was deeply impressed by this machine tool.

At this exhibition, Blue Ocean No. 1 Machine Tool Factory, through joint cooperation with Japan, introduced CNC systems and host machine tool technology and developed the first horizontal CNC machining center in China.

Fu Donghu even chatted with the Blue Ocean First Machine Tool Factory for a long time and was very interested in this thing.

Yu Anshan: "Chu Dong, don't go yet. You two should go to the Blue Sea first and see how the things are."

Looking at Fu Donghu's somewhat puzzled eyes,

Yu Anshan said seriously, "There's a problem with the factory's R&D. The existing machine tools are no longer sufficient to meet production needs. We need to purchase a new one."

"Go do some research and see if we can use this machine."

Fu Donghu didn't rush to agree: "Leader, can you arrange for someone who understands technology to go with us to take a look?"

A CNC center is not cheap!
If I buy this and end up not being able to use it, it will be ruined!
Moreover, as a layman, he cannot explain technical matters clearly, so it is better for him to have someone who knows the subject around him.

Yu Anshan: "Okay! I'll arrange someone for you."

……

quickly,

Yu Anshan decided that Chen Dazhi and Jin Dakui would follow Fu Donghu to Blue Sea to see the machine tools.

These two people are experts in forging and smelting. With them checking and appraising, there should be no mistake.

"My dear, where is my sweater?"

In the evening, Chen's father, who received the order to go on a business trip, opened the chest of drawers and rummaged through the boxes for clothes.
