If you look for where they make truly working vertical ring rolling mills in China, you will immediately come across a bunch of sites with almost identical descriptions. Many people think that the main thing is the price or a beautiful specification, but in reality it all depends on how the mill behaves under real load after six months of operation. I went through this myself when I was looking for equipment for a project in Kazakhstan.
A common mistake is to look at the list of models and ratings on the Internet. Everyone is “the best” there. But in reality, the key point is the production culture of the plant. I saw how at one well-known enterprise, the assembly of components was entrusted to new employees without proper control, and then these components began to play after the first hundred hours. Therefore, the best manufacturer is often not the most popular one.
It is important to look at how the plant approaches the processing of shafts and bearing units. A good manufacturer will have a separate line or even a workshop for this operation, with temperature and vibration control. If everything is done “in the general flow”, expect problems with beating. This is not a theory, but a conclusion after visiting three different factories in Shandong and Henan.
One more point -vertical ring rolling machineoften requires non-standard solutions for a specific product range. If they persistently offer you only standard models, without asking for rolling details, this is a red flag. The best ones, in my experience, start the conversation with questions about the material of the workpiece and the required end accuracy.
Everyone knows about the giants in Shenyang or Wuxi, but there prices are often inflated for the brand, and production flexibility suffers. I found interesting options in Shandong province. There are many enterprises concentrated there that work precisely on “non-standard” lines. and complex tasks. Their websites may look modest, but the engineering staff is strong.
For example, I worked withShandong Shenyang Mechanical Equipment Co.,Ltd. On their websiteshengyangjxgroup.ruthere is no pathos, but it is clear that they are positioning themselves as a high-tech enterprise. What is important is that they do not hide the fact that they take some components (for example, CNC systems) from proven German or Japanese suppliers, and see their area of responsibility in power mechanics and adaptation. This is an honest approach.
There are a couple of other factories in Luoyang that focus on machines for rolling heat-resistant alloy rings. Their machines are more expensive, but if you need just such a niche, then it’s better to look there. They are rarely advertised en masse; they are found through recommendations or through industry exhibitions.
The first is a warranty on the hydraulics and control system. Not for the entire camp, but specifically for these nodes. They fail first. A good manufacturer will give at least 18 months for hydraulic cylinders and servos. If they only offer 12, it’s worth considering.
The second is the presence of a test run on your material. I once had to insist that the factory in Tianjin roll my 40XNMA blank. They reluctantly agreed, and in the process discovered a problem with the roll pressure settings. It’s better to see this before shipment than to figure it out at your site.
Third, who will carry out commissioning. It is ideal if not just an installer comes to the site, but an engineer who participated in the design. UShandong Shenyang Mechanical Equipment Co.,LtdBy the way, there is such a practice. This greatly reduces commissioning time.
There is a lot of temptation to save money here. But with a vertical ring rolling mill, savings of 15-20% on purchase can result in double repair costs in the first year. I think this: if the price difference between two suppliers covers the cost of one major overhaul of the main gearbox, it is better to take more.
An important nuance is the availability of spare parts. Some manufacturers use unique bearings or gears, which can then take months to arrive. Immediately ask for a catalog of spare parts with article numbers and clarify which of them are standard (for example, according to ISO), and which are of your own production. The latter are a potential headache.
Sometimes the ?best? the choice is not the most technologically advanced mill, but the one whose design is simpler and more repairable right in your workshop. Especially if you don’t have highly qualified adjusters. Simple and reliable mechanics sometimes outperform sophisticated but capricious ones.
I had a project where we bought a car from a manufacturer in Jiangsu. The machine looked perfect, but after three months problems began with rolling accuracy. It turned out that the frame was not rigid enough for our cycles, and it was “led?” when warming up. The manufacturer denied the problem for a long time, citing improper operation. Lesson: always request stiffness and vibration calculations for your operating mode. If they are not there, this is a reason to be wary.
Another case, more successful, is connected precisely with the search for a machine for rolling medium-diameter rings. We contacted several suppliers, including the one mentionedShandong Shenyang Mechanical Equipment Co.,Ltd. Their engineers sent not just a commercial proposal, but a technical note with an analysis of our technical specifications and their recommendations for strengthening the frame. It made an impression. In the end they took it from them. The machine has been running for four years now, there are no serious complaints, only scheduled maintenance.
Therefore, returning to the question in the title. The best manufacturersvertical ring rolling machinein China - these are those who are not afraid of dialogue, who are ready to show their “kitchen” and is responsible for its products after sale. They are often searched not in the top search results, but in professional discussions and through a chain of recommendations. Look not at the wrapper, but at the content and the people you communicate with.
