The Kawasaki ZX200S robot performs machine tending between the CNC washing machine, thermal deburring machine and acid washing machine. The robot takes out the valve block from the CNC washing machine and feeds it to the thermal deburring machine. After deburring, the robot cleans up the workpiece's surface for better magnet contact. Using a magnetic gripper, the robot picks up the workpiece and places it on a table to change its orientation. After turning the workpiece upside down, the robot feeds it to the acid washing machine. The workpiece weighs more than 100 kg. The automation of the machine tending process relieved the operator from the dangerous work of handling heavy parts manually.
