Induma Milling Machine

Process

In Friction Stir Welding a rotating tool moves along the weld seam; the high rotating speed of the tool with the frictional forces between the work piece surface and the shoulder of the tool promotes joining by frictional heating, softening and severe plastic deformation. FSW is known to be a highly energy efficient and environmentally friendly process capable of joining various materials.

JR3 Multi-Axis Load Cell

The JR3 multi-axis load cell, also commonly known as a 6 degree-of-freedom force-torque sensor can be used to measure the forces along three orthogonal axes (x, y and z) as well as the moments or torques about those axes with very high accuracy.

Applications

This milling machine equipped with the JR3 load cell may be utilized for friction stir welding or processing of a variety of materials including: all Al alloys, copper and its alloys, zinc and its alloys, magnesium and its alloys, titanium and its alloys, lead, metal matrix composites, and polymers. Due to its high loading capacity it may even be used for steels. It is also possible to investigate tool loading and frictional heating during machining operations with this system, as the load cell can measure loads and total mechanical energy input imposed on the workpiece.
