Hybrid technologies that join concepts and capabilities.
Consolidating metal removal and joining in one multi-task, digital-driven platform requires a distinctively innovative perspective on the manufacturing life cycle.
A leading provider of Friction Stir Welding (FSW) technology since 2002, Megastir became part of the Mazak Corporation in 2018. The company chose IMTS 2018 as its showcase to unveil the VTC-300c's groundbreaking new capabilities.
“At IMTS 2018, it was clear, based on the attendee-buzz and communication from our customer-base that digital manufacturing and hybrid machining was the right direction.”
—Dale Fleck, General Manager, Mazak Megastir
Instead of joining components by changing their states from solid to liquid so that they fuse together as the weld pool solidifies, FSW plasticizes and then homogenizes two components through a combination of frictional heat, forging pressure, and rotational energy. It creates full-penetration, defect-free joints. It can also join dissimilar metals, such as aluminum to copper or steel to nickel-based alloys.
“FSW breaks down grain structure and regrows it in a controlled manner, preserving material properties,” says Russell Steele, Engineering Manager, Mazak Megastir. “Control algorithms continuously optimize performance based on real-time feedback related to temperature, pressure, spindle speed, travel speed and numerous avariables, delivering consistent fusion within a part, between lots and across a fleet of systems.”
“This multi-tasking system exemplifies the non-linear thinking visitors will find at IMTS 2020. It's two traditional solutions but wrapped in a comprehensive digital package that can exponentially increase overall equipment efficiency.”
