The ABB IRB 6400 is one of the most installed robots in the world. Used by most of the major automotive manufacturers for nearly 15 years they have an excellent reputation for reliability and capability and as such are the industry standard.
It is modular in construction and this model has 150kg capacity and 2.4m reach.Â
The S4C controller is a further development of the S4, the “”C”” stands for compact, and it is well regarded for its stability and reliability with a very fast boot up time. Normally supplied with one I/O card giving 16 inputs and 16 outputs it can be fitted with many more if needed. Analogue I/O is also available. The controller can also work as a PLC by controlling and monitoring I/O signals. Up to 3 background programs (for monitoring signals for example) can be run in parallel with the actual robot program and even when the robot program has stopped. Outputs can be set at a specific time or distance before a programmed position and can be executed concurrent to the robot motion. The controller also has built in dual chain (0V and +24V) safety circuits meaning that the robot can be run without the need for extra emergency stop relays etc. Another benefit of the S4C controller over the S3 or S4 is that it is much easier to feed with data as it has an optional Ethernet connection.
The robot arm uses epicyclic (planetary) gearboxes for the major axis and is both simple and reliable. The arm is also very rugged and is less vulnerable to damage than many of its competitors. The robot is entirely powered by ac servo motors, the “”rams”” on the side of the arms are not hydraulic or pneumatic, they are simply enclosed mechanical springs. The springs and weight on the back of the robot make it very well balanced meaning the forces required to move the robot are remarkably small. Life expectancy or MTBF (mean time between failure) is largely dependent on service practices (once a year is normal) but we expect 6400’s to last for at least 100,000 hours.Â
The IRB 6400 arm and controller are both protected to IP54 with the wrist getting additional protection to IP55 this means that the robot is well suited to industrial environments.Â
The IRB 6400 is employed around the world in a multitude of applications including spot welding, MIG welding, palletising, handling, pick and place, machine tending, milling, woodworking, cutting, de-burring, plastics, even NON EX painting and spraying applications.
Now available at very reasonable prices the IRB 6400 is a fantastically useful robot. Our IRB 6400s are supplied complete with the arm, control cabinet (including I/O), cables and teach pendant. We clean, test and repaint them before shipping and give 3 months parts warranty. If you need manuals we can provide them. Most of the IRB 6400â€™s we supply will have around 30,000 hours but this can vary – we are more focused on the robot’s background and overall condition.
Remove the stress & worry of collecting, installing and maintaining your machine.
