Mazak MegaStir Tools & Tool Holders
FSW Tools
An FSW tool consists of a protruding pin that plunges into workpieces and a larger concentric shoulder that remains on the surface of the joint. When tools rotate in contact with the base workpiece material, the action creates frictional heat that produces a plasticized region around the tool.
With extensive FSW tooling experience, Mazak MegaStir is an industry leader in the development of advanced FSW tooling produced from ultrahard materials for specific part material applications. We are the current patent holders for using diamond tool material in FSW joining of aluminum and cooper applications and the original inventors of PCBN tools for steel part applications. Additionally, we currently hold a patent for tools made from our special blend of PCBN.

FSW Tool Holders
With all aspects of effective FSW in mind, Mazak MegaStir continues to lead in the advancement of tool holding technology for the process. Within that technology are the company’s patent Intelligent Tool Holders that allow Mazak machines to seamlessly switch from conventional machining processes to FSW operations with the speed and simplicity of an automated tool change.
Intelligent Liquid-Cooled Tool Holder
For even greater accuracy and process security, the FSW Intelligent Tool Holder is also available with a liquid-cooled variant that provides all the same integrated features with the addition of advanced temperature-control capabilities. Liquid cooling ensures the longest tool life and the strongest possible welds, especially in high-temperature applications or those performed with softer FSW pin materials.
