Xu Zhenming nodded. He is naturally very clear about the difficulty of processing high-precision screw rods, not to mention the screw rods processed with this special glass, so he said: "Yes, level 4 screw is 25 energy coins. One ton! As for screws with other grades of precision, how does Wang always price them?"

"Mr. Xu! The price of the second-level precision screw is ten per energy coin, and the price of the third-level screw is one hundred per energy coin. I don't know what Mr. Xu thinks?" Wang Bin asked.

"Okay! Just do what you said, Mr. Wang!" Xu Zhenming said.

Xu Zhenming did not care too much about the price of secondary and tertiary screws. After all, as high-end products, tertiary and secondary screws are destined to not use too many, even if it is the secondary and tertiary wire he needs. The consumption of rods per month is no more than a hundred rods at most.

"Then Mr. Wang! First, give me a two-ton screw for the fourth-level screw. At the same time, give me a thousand for the third-level screw, and one hundred for the second-level screw." Xu Zhenming said.

Although the quantity ordered for Grade 2 and Grade 3 screws is not large, these quantities are enough for Xu Zhenming's factory to use for about a year. After all, Xu Zhenming's factory has just entered the machine tool production industry. The output is not very much.

"I don’t know Mr. Xu, besides the screw, you also need other products, such as machine bed, machine spindle, machine bearing, etc. made of our glass? If necessary, I can also try Now, can we use our special glass to make these parts." Wang Bin thought about it and asked Xu Zhenming.

At the same time, these machine tool parts mentioned by Wang Bin are very important parts for the machine tool, and they are also parts that are not easy to manufacture. Let alone the other, let's talk about the machine bed that seems the easiest to manufacture.

Generally speaking, the machine bed of various countries, including Wang Bin's world and Xu Zhenming's world, are basically made of gray iron.

After all, the machine bed seems to be cast only by gray iron, but in fact there are many requirements for the machine bed.

The first is the requirements for wear resistance and shock absorption. Because graphite in cast iron is good for lubrication and oil storage, it has good wear resistance. Similarly, due to the presence of graphite, gray cast iron has better shock absorption than steel.

Secondly, in terms of process performance requirements, gray cast iron contains high carbon content and is close to eutectic composition, so it has a relatively low melting point, good fluidity, and small shrinkage rate, so it is suitable for casting complex or thin-walled castings.In addition, because graphite makes it easy to form chip breaking during cutting, the machinability of gray cast iron is better than steel.

Secondly, the hardness and tensile strength requirements.

However, these are the requirements of ordinary machine bed, and those high-precision machine tools are different. Generally, high-precision machine tools have very strict stress requirements, because stress has a huge impact on the accuracy of machine tools.

Therefore, under normal circumstances, high-precision machine tools will not use cast bed, but will adopt a more secure method, that is, use other materials instead of cast bed, such as granite bed.

After all, the precision of high-precision machine tools has very strict requirements. The precision requirements are in the micron level or even the nano level. However, the internal stress generated by the casting bed and the influence of the thermal expansion coefficient will definitely change More than ten microns, especially for medium and large machine tools.

When Wang Bin saw Xu Zhenming buying high-precision screw rods, it was obvious that he wanted to produce high-precision machine tools and even machining centers in the 1980s and 1990s when he was in the world, so they must also have a great need for machine tool bed materials.

The high-temperature resistant special glass produced by Tiangong Technology itself is a special high-temperature resistant glass for aerospace and aviation, and its internal stress requirements are very strict. At the same time, it absolutely reaches high-precision machine tools in terms of heat and cold coefficient. For the requirements of the machine bed, coupled with the performance of the glass itself, it is absolutely feasible to manufacture the machine bed.

It's just that the price of these glasses is too expensive compared to other materials. After all, the price of 15 energy coins per ton is equivalent to 15 million yuan per ton. What's more, one set The weight required by the machine bed is no longer a mere one ton.

Small machine tools are okay. A few tons of glass is definitely enough, but those medium and large machine tools are different. This is a big guy with dozens of tons at every turn!

In the same way, machine tool spindles have very demanding requirements for these aspects, and the performance of their glass is absolutely capable, so now only see Xu Zhenming's choice.

After listening to Wang Bin’s words, Xu Zhenming fell into thinking. Obviously, it is absolutely inappropriate to use these glass to make machine tool beds, etc., to make machine tools for sale. Let’s not say that in his age, it is as high as tens of millions or even several. Will someone buy a machine tool with a price of 100 million yuan? The problem of energy coins alone cannot be solved by money in reality.

Secondly, judging from the contact between him and Wang Bin during this period, Wang Bin and their Tiangong Technology glass production capacity is also very limited.

However, he also thought that since these glass-based machine tools cannot be used for sale, there is no problem in using them himself. After all, as a high-precision equipment manufacturing company, the requirements for equipment precision are endless.

In the past, Xu Zhenming had actually bought some high-precision machine tools in the science and technology mall. However, even in the science and technology mall, there are not many merchants selling high-precision machine tools or machining centers in the post-zero-level civilization area. And the machine tools sold by these businesses are also very high.

Take a three-level precision machine tool as an example. The general price in the science and technology mall is above one million energy coins, not to mention the second and first-level machine tools. As for the price of truly ultra-high precision CNC machine tools, it is even more incredible. The price of one machine is more than one billion energy coins, so if you don't have energy coins, you can't afford these high-precision machine tools.

Although Xu Zhenming had bought some machine tools from the Science and Technology Mall before, the machine tools he bought were only grade 5 and grade 4 precision machine tools. However, the price of these grade 5 precision machine tools in the mall is also Up to tens of thousands of energy coins.

Although these five-level precision machine tools are enough for their year, or for the country of that era.

But as a machine tool manufacturer, who doesn’t want higher precision machine tools, it’s better to have nano-level ultra-high precision machine tools all at once. After all, if they have higher precision machine tools, they will produce them themselves. The accuracy of the machine tools will also be greatly improved, so for the countries of their time, it is definitely a great thing.

And now, for Xu Zhenming, the opportunity is right now. The screw problem in the ball screw has been solved before. If the machine bed, bearing, spindle and other problems are solved, then Xu Zhenming and his company will manufacture some high-precision machine tools for themselves. It's not a problem.
