Promess, Inc. has introduced a new line of lightweight press systems intended for use as end effectors in robotic assembly applications. The L-Series Robot Presses weigh up to 51 percent less than first generation Promess Robot Presses and will initially be available in sizes up to 50 kN capacities offering a 200 mm stroke and 300 mm/sec speed. L-Series Robot Presses also feature a lubrication system that allows automatic greasing of the ball nut. The press design reduces system downtime for lubrication from minutes to seconds and facilitating completely automatic greasing cycles.
