This machine is used for slot cutting of commutator risers. The job is rotated for one turn and the angular position of every copper segment is recorded by means of a laser sensor. Now the job is precisely positioned such that the slotting cutter can cut the first slot in the middle of the segment. After every slot the job is indexed by the precise angular displacement and all slots are cut. Jobs are loaded and unloaded automatically. Average cycle time (floor to floor) for a 23 segment commutator is 16 seconds.
In twin head machines up to 6 slots can be cut in a second.
ETA has developed Friction Stir welding machines of various capacities. Friction stir welding is an Eco-friendly process to weld and produce near nano grain size materials. It is a relatively new solid-state joining process and is useful for joining high strength aerospace aluminum alloys and other metallic alloys that are hard to weld using conventional fusion welding. This environment friendly technology is considered to be one of the most significant developments in the metal joining process.
