The ABB IRB 6400 is one of the most installed robots in the world. The latest revision of this arm, the 6400R is used by most of the major automotive manufacturers for more than 10 years. These robots are known for their reliability and capability, and having the highest industrial standards. The S4C controller includes the servo drive system, the programming language and teach pendant. The controller comes with one I/O card and Analogue I/O is also available if required. The controller can also work as a PLC by controlling and monitoring I/O signals. The controller also has built in dual chain (0V and +24V) safety circuits that the robot can be run without the need for extra emergency stop relays etc. This robot can easily be used with programs supplied by CAD-CAM software system that converts CAD models into robot paths. The robot is entirely powered by AC servomotors, the "rams" on the side of the arms are simply enclosed mechanical springs. The springs and weight on the back of the robot make it very well balanced. This makes the forces required to move the robot remarkably small. Some of the Applications are - Spot welding Part handling Grinding De-burring Finishing Polishing Inspection and testing MIG, TIG and laser welding Palletising Machine tending
