Inline surface finishing for high value components

Uploaded 15 Jun @ 14:18pm

The groundbreaking Rosler Surf-Finisher opens up new possibilities thanks to its ability to precisely finish specific surface areas on high value components in single piece flow. Its compact and highly adaptable plug-and-play system can be easily integrated into existing or new manufacturing lines.

Such high value workpieces include machining tools, engine and transmission components, turbine components and orthopedic implants. For such parts, the surface finishing process, in an automated manufacturing environment, has presented a serious bottleneck. Currently the deburring, edge radiusing, surface grinding/smoothing and polishing is mostly conducted away from the production lines, often with associated low efficiency levels.

The innovative Surf-Finisher provides precise, consistent and cost-effective treatment of high value components even as single piece workflow. And, it makes no difference whether the entire surface or only certain surface areas of complex workpieces require finishing.

At its core, a robot immerses one or multiple workpieces, mounted to a specially designed clamping device, into the work bowl and guides them through the media with pre-programmed movements. This allows for the precise finishing of different shapes and contours as well as specific surface areas on the workpieces. During the process the work bowl rotates at a speed of up to 300 rpm. This generates a very high pressure resulting in extremely short cycle times. At the end of the finishing cycle the robot guides the workpieces to an integrated rinse station before depositing them at a predefined location. With wet processes, in addition to the rotational speed of the work bowl, the process intensity can also be controlled by different water levels in the work bowl.

The new, fully equipped plug-and-play Surf-Finishers, models 700 and 800 F, are designed for workpieces of up to 150 mm long. Processing bowl, 6-axis jointed-arm robot, electrical controls, dosing system, rinse station and a pump unit for the process water, which can be connected to a process water cleaning station, are integrated in the system, with
a footprint of only 2,700 (L) x 1,600 (W) x 2,750 (H) mm. This compact design allows for strategic placement of the finishing system next to pre-existing equipment, such as CNC machining centres.
