Intelligent Tool Holder - Mazak MegaStir

Wireless Multi-Channel Tool Holder Series for Friction Stir Welding

Mazak MegaStir is now offering a patent pending Intelligent tool holder and telemetry system to upgrade milling or routing machines with FSW capability. The tool holder provides high-speed process sampling of customer-selected channels for either tool temperature, z-axis load, or tool torque for maximum control for the friction stir welding process. The system can also be set up with analog outputs for integrated machine control using force or temperature control algorithms.


Wireless telemetry system with load, temperature, and torque measurement capability.
Can be used as a stand-alone device or simultaneously with a PC using USB interface for added utility.
Easy to use “nodes” that are fully rechargeable and connect wirelessly to a USB receiver.
Up to 8 analog outputs for PID control (including output replicates).
