Wittmann Robot & Automation Systems Inc. of Torrington, Conn., has introduced a line of lightweight robots built with carbon fiber components that can help reduce cycle times.
Carbon fiber materials have been used in various robot prototypes, but production units have had high manufacturing costs compared to those made with standard materials.
With Wittmann's new robot line, several axis modules can be made from composite materials as needed. This reduces the robot's moving mass and permits ultrahigh speeds and improved accelerations. The new speeds require specially engineered bearing systems and drive configurations.
End-of-arm assemblies, made of pressurized aluminum die-castings, also are weight optimized.
Wittmann displayed the robots at Plastics USA, held Oct. 6-8 in Chicago. Wittmann also will display the line at K'98 in Dusseldorf, Germany.
The cost of a robot is $75,000.
