Xu Zhenming nodded. He is naturally very clear about the difficulty of processing high-precision screw rods, let alone screw rods made of this special glass, so he said: "Yes, the cost of 4-level screw rods is 25 energy coins. One ton! As for the screw rods of other grades of precision, how does Mr. Wang set the price?"

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

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

Xu Zhenming didn't pay too much attention to the price of the second- and third-grade screw rods. After all, as high-end products, the third-grade and second-grade screw rods are destined to not use too many quantities, even for the second-grade and third-grade screw rods he needs. The monthly consumption of poles is no more than a hundred at most.

"Then Mr. Wang! First give me two tons of screw rods for the fourth grade, and one thousand for the third grade screw rods, and one hundred for the second grade screw rods." Xu Zhenming said.

Although the number of second- and third-level screw rods 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, do you need other products, such as the machine bed, machine spindle, machine bearing and so on made of our glass? If necessary, I can also try Let's see if we can 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 all very important parts for machine tools, and they are also parts that are not easy to manufacture. Let alone the other things, let’s talk about the machine bed that seems to be the easiest to manufacture.

Generally speaking, the bed of machine tools in various countries, including the world where Wang Bin lives and the world where Xu Zhenming lives, are basically made of gray iron.

After all, the bed of the machine tool seems to be made of gray iron, but in fact there are many requirements for the bed of the machine tool.

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 existence of graphite, the shock absorption of gray cast iron is better than steel.

Secondly, in terms of process performance, gray cast iron has high carbon content and is close to the eutectic composition, so the melting point is relatively low, the fluidity is good, and the shrinkage rate is small, so it is suitable for casting complex or thin-walled castings. In addition, the machinability of gray cast iron is superior to that of steel due to the ease of chip breakage during machining by graphite.

Second, hardness and tensile strength requirements.

However, these are the requirements of ordinary machine tool beds, but those high-precision machine tools are different. Generally speaking, high-precision machine tools have very strict requirements on stress, because stress has a great impact on the accuracy of machine tools.

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

After all, the precision of high-precision machine tools has very strict requirements. The precision requirements are at the micron level or even at the nano level. 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 his world in the 1980s and 1990s, so they must also have a great need for machine bed materials.

The high-temperature-resistant special glass produced by Tiangong Technology itself is a special high-temperature-resistant glass for aerospace, and the stress requirements inside the glass are very strict. For bed requirements,

In addition to the performance of the glass itself, it is absolutely feasible to use it to manufacture the bed of the machine tool.

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 per ton. The weight required by the machine bed is no longer a mere one ton.

Small machine tools are fine, a few tons of glass is definitely enough, but those medium and large machine tools are different, this is a big guy with tens of tons at every turn!

In the same way, the machine tool spindles have very strict requirements in these aspects, and the performance of their glass is absolutely capable, so now it is only up to Xu Zhenming's choice.

After listening to Wang Bin's words, Xu Zhenming fell into deep thought. Obviously, it is absolutely inappropriate to use these glasses to manufacture machine tool beds, etc., to manufacture machine tools for sale. Will someone buy a machine tool with a price of 100 million? The problem of energy coins alone cannot be solved with real money.

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

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

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

Take the three-level precision machine tool as an example. The general price in the technology mall is more than one million energy coins, not to mention the second-level and first-level machine tools. The price of one machine is more than one billion energy coins, so if you don't have some energy coins, you can't afford these high-precision machine tools.

And although Xu Zhenming has bought some machine tools from the technology mall before, the machine tools he bought are only five-level and four-level precision machine tools, but the prices of these five-level precision machine tools in the mall are also high. Up to tens of thousands of energy coins.

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

But as a machine tool manufacturer themselves, who doesn't want a machine tool with higher precision? It is best to have a nano-level ultra-high-precision machine tool at once. The accuracy of the machine tool will be greatly improved, so it is definitely a great thing for the country of their era.

But now, for Xu Zhenming, the opportunity is in front of him. He has solved the problem of the screw in the ball screw before. If he is solving the problems of the bed, bearing, and spindle, then Xu Zhenming and his company can manufacture some high-precision machine tools for themselves. Not a problem.
