Hi, this is Morio!

This is the third entry in my blog series on the TF Series, and the second one focusing on the bed.

Today, I’d like to talk about something inside the bed that doesn’t usually get much attention: the **“ribs.”**

“Ribs” refer to the reinforcing structures built inside a machine bed.
Think of it like a box—if it’s just hollow, it tends to wobble. But if you put some supports inside, it becomes much more stable.
You’ll find reinforcement ribs in car bodies or building frames too. And yes, they’re also an important part of our machine beds.

Their biggest role Without a doubt is **to increase the rigidity** of the machine.
Now, what’s “rigidity”? It means **how well a structure resists deformation from external forces.**
Our machines are known for having high rigidity, and that directly contributes to **stable spring processing**.

In other words, this links directly to our company’s motto:

> **“Repeat accuracy” = the ability to keep producing high-precision springs in exactly the same shape, again and again.**

Back to the ribs—by placing them properly inside the bed, we can make the box structure **resist distortion** and **suppress vibrations**.

Of course, we also need to consider costs, so the real challenge for our designers is:

– How can we place ribs **most effectively**?
– How can we design them to be **easy to manufacture**?

Some practical design choices include:

– Placing **more ribs near the top**, where the frame will be mounted.
– Designing the inside of the bed to make it **easy to weld ribs accurately.**
– Considering **thermal flow and vibration damping**, especially since electrical components may be installed inside the bed.

Also, depending on the size of the machine, the relationship with the **wire line** (the spring’s processing height) comes into play.
Larger machines tend to have **lower beds**, while smaller ones have **higher beds**.
So, we carefully decide the **thickness and layout** of both the bed and the ribs, taking into account the size and weight of the units mounted above.

That’s all for today!
Next time, I’ll dive even deeper into the world of “ribs” and how they support our machines behind the scenes.

By the way, this content is also available on our YouTube Channel under the “Posts” section.
We’ve also uploaded many videos and Shorts, so I’d be super happy if you checked those out too!

Stay tuned and see you next time!
