Chapter 27 (2/2)

However, ball screws above grade P5 can not be processed by ordinary machine tools, especially those above grade P3.

In addition, the material of ball screw above P3 or P4 is no longer ordinary screw material.

The most important thing is that for processing such a grade of ball screw, in addition to the machining accuracy of the machine tool must be above grade 3, there must be other supporting equipment, such as professional grinding and polishing equipment.

Therefore, if you want to produce ball screws below P5 level, you don't need any good machine tools at all. Generally, hundreds of thousands of machine tools on the market are OK.

However, if you want to produce P5 or above, you can't solve it by hundreds of thousands. At least those machine tools with prices of tens of millions are needed.

However, uncle Qin advised you not to produce such products as ball screw. Although the investment of low-grade products is small, they are already the price of cabbage. Even if they are produced, there is no profit.

The investment of those with high precision level is not small. The most important thing is that even those with high precision level, such as P4 and P3, are not very expensive and the competition is not small. In addition to competing with domestic peers, they also have to face the impact of foreign ball screw manufacturers with better price and better performance. ” Qin Fei said.

After listening to Qin Fei's words, Wang Bin didn't speak immediately. Instead, he was thinking about the precision level of ball screw required by Xu Zhenming, or the precision level of ball screw suitable for Xu Zhenming's world. If the precision level of ball screw required by Xu Zhenming must be above P3, Wang Bin had no way. Let alone the glass of Tiangong technology, Whether it can be processed into this grade of ball screw, only production is a big problem.

Of course, ordinary P5 grade ball screws are not good. After all, P5 grade ball screws may have been processed in Xu Zhenming's era. They don't need to be purchased from him at all, so they must be above P4 grade.

However, he thought that at least P4 and P3 levels should be enough for that era, or the world where Xu Zhenming lived.

So he asked Qin Fei, ”Uncle Qin, I don't know what the price of a slightly better three-level precision machine tool is now?”

Seeing Wang Bin's expression, Qin Fei knew that Wang Bin certainly didn't give up the idea of producing ball screw. However, since Wang Bin insisted on producing ball screw, Qin Fei couldn't say anything. It's a big deal. When he hit a wall, Wang Bin will naturally know his pains.

Now if he says anything more, Wang Bin will certainly think he cares too much or has ulterior motives.

Of course, if Wang Bin really has a stable sales channel, let's say otherwise.

At this time, he suddenly thought that Wang Bin's Tiangong technology was cooperating with 969 military industry group. If they could get the order of 969 group, Wang Bin's Tiangong technology could not produce ball screws.

”OK! Since you are determined to produce ball screw, I can't say anything. As for the three-level precision machine tool you want to buy, there is no problem. Nanfang industry, which was previously sold to your Tiangong technology glass production line, has a three-level precision processing center.

And compared with other domestic machine tool manufacturers, the machine tool performance of their southern industry is still good.

Although their machine tools can not be compared with the performance of international top peers, at least in China, they are at the upper middle level. Most importantly, in terms of cost performance, the machine tools of southern industry are much more suitable than others.

And now you are just preparing to produce ball screw, so you don't need too good machine tools. After all, the prices of those international top machining centers are too high, ”Qin Fei said.

”Well, I see. Thank uncle Qin. I'll call president Zheng when I get back.” Wang Bin said.

Later, Wang Bin and Qin Fei talked for a while. He went out of Qin Fei's office and came to the unloading area of their Qin's industry.
