Xu Zhenming nodded. He was naturally very clear about the difficulty of processing high-precision screws, let alone the screws processed using this special glass. So he said: "Yes, the level 4 screws are 25 energy coins per ton! As for other screws with precision, how did Mr. Wang price them?"

"Mr. Xu! The price of a second-level precision screw is 1 energy coin and a third-level screw is 100 energy coin. I wonder what Mr. Xu thinks?" Wang Bin asked.

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

Xu Zhenming didn't care too much about the price of second-level and third-level screws. After all, as high-end products, the third-level and second-level screws are destined to be used not too many times. Even the second-level and third-level screws he needs, the monthly consumption is only a hundred or so.

"Then Mr. Wang! First, give me two tons of screws for level 4, and at the same time, give me one thousand screws for level 3, and give me one hundred of screws for level 2." Xu Zhenming said.

Although the number of second- and third-level screws is not ordered, these quantity is enough for Xu Zhenming and his factory to use it for about a year. After all, Xu Zhenming's factory has just entered the machine tool production industry, and the annual output is not very large.

"I wonder Mr. Xu, in addition to screws, do you need other products, such as using our glass-made machine tool bed, machine tool spindle, machine tool bearing, etc.? If necessary, I can also try it out, can we use our special glass to make these parts?" Wang Bin thought for a while and asked Xu Zhenming.

At the same time, the machine tool parts mentioned by Wang Bin are very important components for machine tools, and they are also parts that are not easy to manufacture. Not to mention other things, let’s talk about the machine tool bed that seems to be the easiest to manufacture.

Generally speaking, machine tool beds in various countries, including the world where Wang Bin is located and Xu Zhenming is located, are basically made of grey tin.

After all, the machine tool bed body seems to be just cast from gray iron, but in fact there are many requirements for the machine tool bed body.

The first is the requirement of wear resistance and shock-removing properties. Since graphite in cast iron is conducive to lubrication and oil storage, it has good wear resistance. Similarly, due to the existence of graphite, gray cast iron has better shock-removing properties than steel.

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

Secondly, hardness and tensile strength requirements.

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

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

After all, the precision of high-precision machine tools has very strict requirements, with precision requirements being micron or even nanometers. However, the internal stress generated by casting the bed and the influence of the coefficient of cold and heat expansion, the variables will definitely exceed more than ten microns, especially for medium and large machine tools.

When Wang Bin saw Xu Zhenming buying high-precision screws, it was obvious that he wanted to produce high-precision machine tools and even machining centers in his world, that is, in the 1980s and 1990s, so they must also have very much 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. The stress requirements inside the glass are very strict, and at the same time, the cold and cold coefficients are absolutely met. The requirements for the bed of high-precision machines are absolutely feasible to add the performance of the glass itself to make the machine tool bed.

However, 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 the price of 15 million per ton. What's more, the weight required for a machine tool bed is no longer something that can be solved by just one ton.

Small machine tools are fine, a few tons of glass is definitely enough, but those medium and large machine tools are different. These are big guys that often cost dozens of tons!

Similarly, the machine tool spindle has very strict requirements on these aspects, and their glass performance is absolutely competent, so now it only depends on Xu Zhenming's choice.

After hearing Wang Bin's words, Xu Zhenming fell into thinking. It was obvious that if these glasses were used to make machine tools for sale, it would be absolutely inappropriate. Not to mention whether anyone would buy machine tools worth tens of millions or even hundreds of millions of dollars in his era. The problem of energy coins alone was not solved by real money.

Secondly, judging from his contact with Wang Bin during this period, the production capacity of glass such as Wang Bin and his team are also very limited.

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

Before, Xu Zhenming had actually bought some high-precision machine tools in the technology mall. However, even in the technology mall, in the zero-level late-civilized area, there are not many merchants for sale, and the machine tools sold by these merchants are also very high.

Take the third-level precision machine tools for example. The general price in the technology mall is above one million energy coins, not to mention the second-level and first-level machine tools. As for the price of truly ultra-high-precision CNC machine tools, it is even more amazing. The price of each one is above 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 purchased some machine tools from the technology mall before, the machine tools he purchased were only five-level and four-level precision machine tools, but the price of these five-level precision machine tools in the mall was as high as tens of thousands of energy coins.

Although these five-level precision machine tools are enough for them that year, or in China at that time.

But as a machine tool manufacturer, who doesn’t want machine tools with higher accuracy? It’s best to have nano-level ultra-high precision machine tools at once. After all, if there are higher precision machine tools, the accuracy of the machine tools they produce will be greatly improved. This is definitely a great thing for the countries of their era.
