A friction welding machine ( 1 ) has two headstocks ( 5, 6 ), two spindles ( 8, 9 ) with a spindle drive ( 12, 13 ) and a workpiece holder ( 22 ). The first headstock ( 5 ) is arranged stationarily at the frame ( 2 ). The second headstock ( 6 ) is mounted axially movably at the frame ( 2 ) and is connected to a feed drive ( 25 ). The spindles ( 8, 9 ) have different sizes, the second spindle ( 9 ) and its spindle drive ( 13 ) being designed to be smaller and weaker.
