Friction Stir Welding (FSW) Machine

​
​

One of the essential technologies in manufacturing fields such as aircraft, automobile bodies, and bridges is joining.
Welding is one of the joining methods, and there are various techniques such as arc welding and resistance welding.
Recently, a high-profile next-generation technology is Friction Stir Welding (hereafter referred to as FSW).
FSW was developed in 1991 by TWI (The Welding Institute) in the United Kingdom.
It works by softening the materials to be joined using frictional heat generated by a rotating cylindrical welding tool, and then stirring them together to form a solid-state joint.
Since the materials are not melted during the process, FSW achieves high fatigue strength and minimal welding deformation.

Komatsu NTC technology

FSW technology addresses challenges such as dependence on engineers' experience and the transfer of skills from veteran workers.
We encourage you to implement this innovative solution at your manufacturing sites.

FSW dedicated design

Each axis slideway has been enhanced for high rigidity to ensure stable machining, and the spindle has been specially developed for dedicated use in FSW. 

Optimal control of stirring & plasticity

Pushing amount and robot pressurization are controlled to achieve optimal stirring, plastic fluidization, and joining.

All-around machine tool manufacturer

We have built an extensive supply record and customer support for automotive, battery or semiconductor industries.
