So all the talks about securing batch production of materials for WS-20 (and WS-19) are for an improved variant I suppose.

WS-20 will expand like WS-10 family. we have seen one latest example in AEF-1300 engine. civil variant of WS-20

high thrust variants coming soon. so they were talking about materials for those version.

Shenyang also working on WS-20 successor.

Not sure they would need to rip out foreign tools though. Keep them until you can’t service them. If bans prevent them from being serviced swap them out then.

So what if they ban? Just keep on using your properties, until they cannot be repaired.

China have complete set of indigenous machines tools. from A to Z. some are not efficient as German/Japanese counterparts but good enough to finish their job.

Chinese military industrial complex and military aviation mostly using domestic tools.

KEDE and Chongqing Machine Tool (Group) Co., Ltd are top players in machine tools.

see this. my old post about Chinese Machine tools.

nope. first of all you need to know one thing. super advanced CNC machine don't required in aero engine except some precision metals cutting. engines and other high end industrial components requires of complete set of machine tools like CNC machine , drilling machine , grinding machine , milling machine , boring machine , shapers and planers.

this is laser drilling machine. widely used in turbine blades manufacturing.

this machine developed by Xi‘an Institute of Optics and Fine Mechanics.

This is 5 axis CNC machine developed by Chinese firm KEDE. is among the most advanced in the world.

Chongqing Machine Tool (Group) Co., Ltd. one of leading players globally.

this Chinese firm basically produce all types of machine tools, requires in heavy engineering. Chinese military industrial complex mostly used their tools.

Drive to manufacture domestic tools pays off

By ZHANG XIAOMIN in Dalian, Liaoning | China Daily | Updated: 2022-07-18 09:14
About 100 five-axis computer numerical control machine tools are being produced in the manufacturing shop at the Dalian Guangyang Technology Group in Jinpu New Area in Northeast China's Liaoning province.

"We've applied for some 20 international patents for this processing center, which is capable of processing large structural aircraft parts," Yu Dehai, president of the company, said while standing in front of a large machine tool.

Dalian Guangyang is a leading manufacturer of high-end CNC machine tools in the country.

In the office above the workshop, 71-year-old Yu works with the researchers and developers that account for more than a quarter of the company's 1,200 employees.

"I'm lucky that what I'm working on matches my passions. It is the same with our R&D colleagues. It is easier to achieve good results by combining work with interests," Yu said.

Previously, China's high-end CNC machine tools market was dominated by a couple of major foreign manufacturers. Yu and his colleagues changed that with the cost-effective products they developed.

"This is our main driving force for following a path of independent innovation," Yu said.

"We will produce the world's most advanced five-axis CNC machine tools and make exorbitantly priced imported machine tools a thing of the past."

According to Yu, the five-axis CNC machine tool sector is part of the core competitiveness of the country's manufacturing industry, as it has a decisive influence in a number of industries.

now you see, there are a lot Chinese firms, actually produce high end machine tools.


precision manufacturing requires tools , skilled labor and competent environment. China actually improved a lot and rapidly closing the gap with top players like USA and Germany. i think this is what tphuang trying to say this.

The risk is that it could delay production expansion during war time. Bans can and do happen suddenly. If it happens just as production needs to be ramped up in a total (read: not limited) war, it could be disastrous especially if some of your existing factories also get hit / sabotaged at the same time.

Of course it doesn't matter in a limited conflict because existing inventory is all that's relevant. But in a total war, industrial capacity is critical.

What's the current progress on the WS-15? I've heard rumours floating around that its finished and is may be entering mass production soon.
