Hi, this is Morio!

Welcome to another post in our TF series—this time, we’re diving into the “manufacturing side” of the machine bed!
We’ve already talked about the bed’s structure and the role of ribs, but have you ever wondered how the bed is actually built?
That’s what we’re exploring today—from a real-world, factory-floor perspective!

🛠 So, how is a bed made?

The bed of the TF series is created by welding steel plates into a box-like shape.

But… it’s not as simple as just welding pieces together!
There are a lot of “watch-out points” during the process.

🔍 The first step: Check the steel plates!

Before anything else, we use a gauge to check if the plates are warped.

“If the base material is already distorted, everything you build on top will be off!”

That’s why this step is basic but absolutely critical!

🔥 The welding order is everything!

As we weld each part of the bed together, the heat causes the metal to expand and contract.
This naturally leads to some warping—but that’s where technique comes in!

The order of welding is key to preventing distortions:

• Weld diagonally to balance stress
• Proceed symmetrically to avoid one-sided shrinkage

It’s like solving a puzzle—you really have to think about the sequence.

If you don’t, you might end up with the opposite corner lifting up as you weld. Not good!

🏗 Gantry-style beds are especially tricky!

When it comes to gantry-style beds used in secondary processing machines, things get even more delicate.

As you weld the steel plates, a force pulls them inward.
If you’re not careful, the structure might get pulled in and misaligned.

This is known as the toughest part of bed fabrication—it’s where the skills and intuition of a master welder really shine ✨

📐 For large beds: Keep it square!

Large beds tend to warp into parallelograms if you’re not careful.
That’s why during pre-assembly, we pay close attention to whether any gaps appear between components.

This part requires multiple checks with measuring tools.
We make absolutely sure everything fits snugly—no gaps allowed!

🧰 Tapping holes: The drill makes the difference!

To attach parts to the bed, we need to create tapped holes (threaded screw holes).
What’s crucial here is keeping those holes perfectly perpendicular.

At our partner companies, they use magnetic-base drills to attach firmly to the bed and ensure precision.

This not only helps maintain vertical alignment but also reduces the chance of drill bit breakage.

And of course, the sharpness and maintenance of the drill are part of the craftsmanship too.

Taking good care of your tools—that’s where manufacturing excellence begins!

✨ Summary

The TF series bed isn’t just tough—it’s smartly built.

From avoiding distortions, to heat control, to ensuring the precision of every hole—it’s full of small tricks and thoughtful touches from the factory floor.

These “invisible techniques” are what allow our machines to keep making high-precision springs over the long term.

Isn’t that amazing?
