  • Friction stir processing apparatus and friction stir processing method
    Patent number: 9162318
    Abstract: A friction stir processing apparatus comprises a tool, a processing head retaining the tool, a support table retaining the workpiece, and a cylinder unit biasing the support table toward the tool. The tool having a probe projecting from a shoulder surface, for performing friction stir processing on a workpiece made of a metal material. The processing head is pressing the tool against the workpiece so as to relatively shift the tool in a processing direction. The friction stir processing apparatus comprises load control means for controlling to constantly keep the bias force of the cylinder unit so as to constantly keep pressurizing force of the tool pressing the workpiece. It is thus possible to perform friction stir processing with excellent quality even when the workpiece has a different thickness or is made of a different material.
