Challenges in automated polishing of thin-walled components: Force-controlled floating grinding heads enable flexible processing for industrial robots

2026-09-01 views:8

During the processing of aluminum alloy thin-walled housings, plastic casings, and composite material components, polishing and grinding are highly susceptible to deformation under pressure, a persistent challenge for major manufacturing facilities. Conventional industrial robots struggle with controlling the rigidity of grinding force, resulting in persistently high scrap rates. Force-controlled floating grinding heads have emerged as the key solution to this problem.

The force-controlled floating polishing head supports precise setting of the polishing pressure, allowing for gentle polishing with minimal force. When the polishing contact force exceeds the set threshold, the floating structure automatically retracts to provide cushioning, preventing excessive pressure from compressing thin-walled workpieces and causing deformation. The response time is measured in milliseconds, ensuring continuous and stable polishing force maintenance.

Combined with industrial robots to achieve multi-angle processing, both internal and external curved surfaces, as well as edges and corners of the workpiece can be uniformly polished. The force control parameters can store multiple sets of formulas, allowing direct retrieval when switching between different specifications of workpieces, making it suitable for mass production of multiple models of housings.


Compared to manual polishing, automated solutions ensure uniform surface textures without the inconsistency of variable quality. For the bathroom and consumer electronics industries that prioritize aesthetic quality, industrial robot polishing solutions equipped with force-controlled floating grinding heads have become a standard choice for quality enhancement.
