A Study on Friction Welding by Use of an Automatic Lathe

The Swiss-type automatic lathe is designed to produce small-diameter and long rods with high accuracy efficiency. However, its unique mechanism causes the disadvantage of a large amount waste material. This can be solved by use friction welding method. Friction uses frictional heat generated mechanical rotational energy applies lathes two opposing spindles high-precision positioning functions. performed machine. machine has rigid for hydraulic pressure control. Therefore, there are some differences between machines configurations. In research, authors optimized conditions on using tensile strength evaluation joined workpieces as an index.
