Innovative robotic solution: fully automatic Vibratory Finishing
Fully automatic operation
At the center of this groundbreaking fully automatic system is a robot equipped with a gripper that vibrates at very high frequencies during the HFF process. Different grippers are utilized to accommodate the various work piece shapes and sizes. After the machining operation the parts are placed on a conveyor belt in an exactly defined position. Once they arrive at the finishing system the robot picks up four parts at a time. In a first step - degreasing and cleaning - the robot dips the parts into a cleaning tank. This is followed by the HFF vibratory finishing process including a rinsing and blow off phase. Finally, the robot places the aluminum components back on the conveyor belt for transport to the next manufacturing operation.
HFF - excellent and repeatable finishing results in short cycle times
During the HFF process the robot gently dips the high frequency vibratory gripper with the 4 mounted work pieces into the work bowl filled with spherical stainless steel media. The gripper vibration with 3000 RPM and the movement of the steel media induced by the vibratory drive of the mass finishing machine produce an intensive and homogeneous media flow around the work pieces. Furthermore, during the finishing process the robot can take the work pieces out of the work bowl to turn them at a defined angle and dip them back into the media mass. These two independent media movements, in combination with the compound and media precisely adapted to this process, yield excellent and absolutely repeatable deburring and polishing results in very short cycle times.
Depending on size and shape of the respective work pieces, the complete operation, including picking the parts up and placing them back on the conveyor belt, lasts between 180 and 300 seconds.
