Sanding & Polishing

Sanding, deburring, polishing, and surface finishing automate processes that smooth surfaces and improve finishing quality.

Because quality depends on pressure, speed, path, and material condition, robot-based precision control has a strong impact on consistency and safety.

Key Benefits

Precise pressure and path control
provide consistent surface quality and high work stability.

01 Reduced Quality Variation

Maintain pressure, speed, and the transport path at a constant rate
Ensure uniformity of surface quality.

02 Reduced Operator Burden and Risk Exposure

Automating dust, vibration, and noise environments
Minimize physical fatigue and exposure to harmful elements

03 Support for Complex Curves and Shapes

Even in curved surfaces, corners, and irregular regions
Sanding and polishing with consistent quality are possible.

04 Higher Productivity

Even during long, repetitive tasks
Overall throughput increases by maintaining speed and quality

Technology Highlights

Rainbow Robotics robot platforms
provide force control, path control, and tool compatibility for consistent precision finishing.

01 Uniform Finishing Quality Based on Smart Force and Pressure Control

Pressure control, a core function in sanding and polishing, is realized through force- and torque-based precision control technology.
When using robots, pressure is maintained consistently at each location, enabling more uniform surface quality than the work performed by human labor. It provides stable finishing quality, especially on curved surfaces and areas with many surface variations.

02 Broad Compatibility with Sanding and Finishing Tools

It can interface with a variety of tools such as electric and pneumatic sanding heads, grinding discs, foam pads, and bur removal tools, enabling work setups tailored to the characteristics of materials such as wood, metal, plastic, and composites.
When linked with the tool change system, process transitions are also carried out quickly.

03 High-Precision Path Control for Irregular and Curved Surfaces

Even products with complex shapes such as curved surfaces, edges, corners, and inclined planes can be machined repeatedly by accurately following a designated path through the robot’s high-precision path control.
It ensures more consistent quality and reproducibility than handcrafting.
