The cage can evenly distribute the rolling elements and guide the rolling elements to rotate to lubricate.

It can be seen that among the four parts, the rolling element is the most critical, followed by the ferrule.

The structure seems to be very simple, but it is difficult to do it well. After all, it is materials and heat treatment processes.

There are generally four types of materials for ferrule and rolling elements:

The first type is high-carbon chromium bearing steel, which can be used for general mechanical requirements. If the requirements are higher, vacuum smelting technology is used;

The second type is carburized bearing steel, which can be used under large impact vibration conditions, such as bearings for rolling stocks and steel rolling mills. The heat treatment process of this steel is relatively complicated.

The third type is heat-resistant bearing steel, which is suitable for working temperatures of 120 to 250 degrees Celsius, such as spindle working conditions such as aircraft engines, gas turbines, etc.

The fourth category is corrosion-resistant bearing steel.

The material requirements for cages are not that high.

Generally, the ferrule and roller are H60~64, and the steel ball is H60~66. This hardness is better than the blade hardness of a good household kitchen knife.

Of course, some top-notch technologies can achieve 66+ hardness of the ferrule and roller, and the toughness is good.

Xinghai Group cannot study so many of the four major categories of materials at once, and it must be done the same thing.

In the steel structure factory No. 6, the Xinghai Group Headquarters Base, this factory is a steel casting and forging laboratory, which specializes in smelting small batches of steel for experiments.

Near the aluminum alloy factory, Xinghai Group has invested in the construction of a bearing casting and forging factory with 500 acres and a bearing heat treatment factory. After the materials are made, they will be transported to the bearing factory at the second phase headquarters base for processing and assembly.

These three factories are expected to be put into use in the middle of next year.

At the end of November, Mu Yang re-formed and sorted out the 48 plan.

[1 Hummer EV was delivered 50,000 units by July 2013, and the current progress is: 6230/50,000;

[8 Xinghai Group has completed a turnover of 60 billion yuan, and its current progress is 100%]

Muyang also purchased the technology of CNC machine tools, and the progress is currently slow.

In terms of new energy vehicle project research and development, Xinghai Group has made a big breakthrough. In the next year, Muyang will not invest much energy in new energy vehicles.

Only when 3D printers and chips make a big breakthrough will it develop into flying cars.

Now, the core undertakings in the next two or three years have formed two main routes:

Article 1: servo motor, bearing and screw-type CNC machine tool → 3D printer → top CNC machine tool → industrial master machine;

Article 2: Crystal → Lithography machine or new technology → Chip design.

The development of the first main line has just started for a few months and progress has been relatively slow.

The second main line will not officially start until next year, and it has been recruiting relevant talents in the past two months.

At 10 o'clock in the morning on December 1, Muyang convened a middle- and high-level meeting of the Technical Department.

Xinghai Group now has 13 technical departments, among the 8 wholly-owned subsidiaries, namely Xinghai Machinery Processing Co., Ltd., Xinghai Laser Technology Co., Ltd., Xinghai Welding Technology Co., Ltd., Xinghai Materials Technology Co., Ltd., and Xinghai Outdoor Equipment Co., Ltd.

Xinghai Automobile Co., Ltd., Xinghai Machine Tool Co., Ltd. and Xingyun Co., Ltd.

After the participants arrived, Mu Yang went straight to the topic: "Today's meeting mainly involves new layouts and new personnel appointments.

The group has newly established Xinghai Machine Tool Co., Ltd. and Xingyun Co., Ltd., which mainly develops CNC machine tools, and our top CNC machine tools in China.

In the past few months, our servo motor, bearing and screw project team has also laid the foundation for CNC machine tools.

The first generation of CNC, a hardware CNC system composed of electronic tubes, has now developed to the sixth generation of CNC, a general-purpose CNC system using industrial control PCs.

In terms of machining accuracy, in the past 10 years, the machining accuracy of ordinary CNC machine tools has gone from 10μ to 5μ to 5μ, precision machining centers from 3 to 5μ to 1 to 1.5μ, and the ultra-precision machining accuracy has begun to enter the nano-level (0.001μ).

;

In terms of speed, the spindle speed has reached more than 100,000r/n...

CNC machine tools are developing towards flexibility and functional integration. In the future, no, there are laboratories that are developing towards intelligence, with adaptive control of the processing process, automatic load recognition, automatic generation of process parameters, dynamic compensation of motion parameters, intelligent

Diagnosis, intelligent monitoring and other functions.

Everyone, my country's top CNC machine tools rely too much on imports. Many CNC machine tools in our workshop can be said to be mostly imported. It is not that I don't want to buy domestic CNC machine tools, but that I can't buy suitable ones. This is very sad.

In the past, I heard employees introduce our company's CNC machine tools to outside guests, saying that it was Trouble Express, Mazak's, and the island country next door, and had a show-off tone.

There is nothing to show off about this, but I find it a little harsh.

We brag outside, Xinghai Group has many world firsts in the field of machinery. It is indeed, but many of our world firsts are processed by other people's equipment, so what's there to show off?

If one day we can replace the CNC machine tool in the workshop with domestic CNC machine tools, or even our own, that is worthy of pride.

If we do not solve the problem of top CNC machine tools, there will be many troubles in the future and are restricted everywhere. We must be aware of danger in times of peace."

Mu Yang said a very serious topic at the beginning, and the atmosphere in the conference room was a bit depressing.

Mu Yang took a sip of tea, moistened his throat, and continued, "Now, the outside world says that our Xinghai Group is a national enterprise. To be honest, I don't think there is anything good, this hat is not easy to wear.

Overseas, many media have also reported on the threat theory of Xinghai Group.

Is there a threat to our Xinghai Group?

It is true that most international arc welding machine manufacturers have been killed by us, and aluminum alloy manufacturers have also been crazy by us. International ternary lithium battery manufacturers have been ravaged by us. LG wishes to blow up our lithium battery factory. I and you

Tell me, there are so many companies that want to blow up our Xinghai Building.

I will live on the top floor after a while, and some employees say it is very comfortable to live on it.

I don't think that I live on it, and I always think about these international competitors thinking about how to destroy us."

"I officially announced the new appointment, bearings and screws are under the jurisdiction of the Materials Company, and the special alloy steel project team was established, and the general project technical manager is.

3D printing equipment is under the jurisdiction of laser companies, and the additive project team is established. The general project technical manager is...

The technical manager of CNC company is... CNC machine tools, bearings and screws are independent. In fact, they are currently for 3D printing equipment services, so you three need to communicate more."

"The newly established Nebula Technology Company is responsible for the manufacturing of crystals, chip manufacturing and chip design. The general project technical managers are... "

Projects such as 3D printing have been in progress for a while, but the technical manager has not decided. Mu Yang inspected the team leaders of each project team to see who is more suitable to be the technical manager of the general project. A total of 5 general project technical managers were appointed.

Nebula Technology Company will have a lot of investment, including crystal manufacturing, chip manufacturing and chip design, so three technical managers are divided into different fields.

If the technician reaches a certain number, the technical director level will be set.
