Surf Finisher – the new standard for precision surface finishing
With its many technical features the innovative Rösler Surf Finisher opens completely new possibilities for the precise, targeted dry or wet surface treatment of complex components. The heart of this finishing center consists of one, occasionally, two 6-axis robots and a rotating work bowl filled with specially selected grinding or polishing media. The work bowl comes in different sizes allowing the treatment of relatively large components or the simultaneous, entirely touch-free finishing of multiple work pieces.
The robot fulfills two functions: For one, equipped with a specially designed gripper, it performs a material handling task by picking up the work pieces from and returning them to a transport belt, immersing them into the work bowl and conveying them to a cleaning/rinsing station. In a second function the robot is guiding the work pieces through the processing media in pre-programmed movements including defined treatment angles, different immersion depths and rotary motion. This flexibility allows the targeted finishing of specific surface areas on the work pieces.
During the complete process the work bowl with the processing media is also rotating at a speed of up to 80 RPM. The actual speed is determined by the work pieces to be treated and the respective finishing task. The robotic movement and the work bowl rotation create a “surfing” effect with a very high pressure between work piece and media. This pressure with the concurrent intensive surface smoothing effect produces perfect finishes within relatively short cycle times. Even with complex work piece geometries surf finishing generates surface readings of as low as Ra = 0.04 µm (1.6 micro inches).
