FLORENCE, Ky., August 12, 2019 – A part of Mazak’s family of HYBRID Multi-Tasking machining centers, the VTC-300C FSW combines milling capabilities with those of FRICTION STIR WELDING (FSW). With a full traveling-column design, automatic tool changer and powerful 40-taper spindle in addition to the FSW package, this machine helps shops achieve reduced lead times and greater part accuracy with less required capital equipment and floor space – all while enabling completely novel methods for processing parts with stronger welds than ever before.
Designed and manufactured in Kentucky in partnership with the Provo, Utah-based Mazak MegaStir, the VTC-300C FSW joins Mazak’s series of HYBRID Multi-Tasking machines, which adds such capabilities as advanced additive, joining and gear-cutting technologies to the world-class Multi-Tasking capabilities found in Mazak machines.
The machine’s FSW package uses a process that involves frictional heat and forging pressure to create full-penetration, defect-free welded joints stronger than conventional methods. A solid-state joining process with a non-consumable tool pin, the Mazak FSW head joins two metal plates without melting the workpiece. Commonly considered a forging process, FSW is well-suited for joining alloys with low melting points, including aluminum, copper and brass, among others.
MegaStir, which was acquired by Mazak in late 2018, has led the industry with improved FSW tool material innovation and applications since 2002. Mazak first collaborated with MegaStir on the full 5-axis VTC-800 FSW Vertical Machining Center. The new Mazak MegaStir will continue to pursue further system advancements while providing technical expertise as the future home of a full FSW technology center.
