Hi, it’s Morio♪

Starting from this post, I’ll be diving into our TF series for extension springs.

To be honest, I felt it was a bit too much for me, so I tried resisting and asking my senior co-workers for help. But they just brushed me off with “Well, everything is a challenge, so do your best!”

The TF series is one of our most popular products and involves a lot of technical aspects. This will be a long journey, but I plan to explore it while making a few detours along the way.
Please don’t abandon me!

Now, let’s start with the machine’s structure.

Since the TF series is also a machine tool, it has the following basic components:

1. Bed
“Bed” is the foundation of the machine. In general machine tools, it is made of cast iron or carbon steel.
For the TF series, we use carbon steel.

Its role includes:

Supporting the entire machine and minimizing vibrations during processing
Firmly securing the frame

In the TF series, not only the main frame but also secondary processing units are attached.
The bed is one of the most critical structures for ensuring machine durability and spring accuracy.
It has a box-type structure reinforced with ribs.

2. Frame
“Frame” is positioned on top of the bed and serves as the mounting base for machining units.
In the TF series, it consists of two plates, one in the front and one in the back.

Its role includes:

Providing stable support for each machining unit
Reducing vibration during processing to improve precision
Enhancing the overall strength of the machine tool

3. Machining Unit
The machining unit is where the spring processing tools are mounted.
The TF main unit is equipped with the following machining units:

Feed Unit: Feeds the wire into the machining section
Torsion Attachment: Bends hooks and processes the body coil section
Machining Slide: Lifts hooks and performs cutting
Push Pitch: Adds pitch to the spring

The secondary processing machine is equipped with the following machining units:

Arm: Transfers the spring (which still has an unfinished rear hook) from the main unit to the secondary processing machine
Rotor Arm: Rotates the transferred spring to the correct angle for rear hook forming
Slide: Raises the rear hook
The machining unit consists of visible components as well as parts that transmit the movement of the servo motors to the machining units, such as shafts and gears.

4. Attachment
Attachments are additional devices that expand the range of processing capabilities.
For example, one of the attachments enables three-dimensional tool movement when raising the front hook.

5. Machining Tools
Machining tools are mounted onto machining units or attachments and physically contact wire material to perform processing.
The TF series includes the following machining tools:

Feed Rolls
Wire Guides
Bending Dies (Coiling Points)
Lifting Tools, Support Tools
Cutters, Cutting Support Tools
Arbor / Mandrel
Pitch Tools
Spring Chuck

6. Control System
The control system consists of a CPU, servo drivers, and servo motors, which manage the movements of machining units and ensure proper data communication.
In the TF series, there are control components housed inside the bed as well as a separate control box.
(Servo motors are mounted onto the frame.)

7. Operation Panel
The operation panel is the monitor section where machining programs and production management settings are entered.
It is connected to the bed and consists of a touchscreen, button controls, and a computer.
The data created here is communicated to the control system, which then directs the actual machining unit movements.

Additionally, sensors for quality control are also utilized.

Wrapping Up
Since this is the first post in this series, I provided a simple overview of the machine’s structure.
Moving forward, I’ll be diving deeper into each topic while occasionally going off on tangents!

Stay tuned for the next post!
