You have 25 polishing workers. Three quit last month. Two more are threatening to leave. Your overseas buyer just sent an email: "Next shipment rejected — Ra 2.8, spec is Ra 1.6. Fix it or we cancel the order."

Walk into any traditional metal-finishing workshop and you will find the same scene: rows of workers hunched over workbenches, coated in metallic dust, grinding parts by hand. It is skilled work. It is also one of the most variable, costly, and hazardous processes in the factory.

Every metal part that comes off a casting line, CNC machine, or stamping press carries an unwanted companion: burrs. These tiny, sharp edges may seem insignificant, but in precision manufacturing, they are anything but. Burrs compromise part quality, damage downstream equipment, injure workers, and create rejection risks that can derail entire production schedules.

Force-control polishing is a key technology in robotic metal finishing. It allows robots to maintain consistent contact pressure with the workpiece, ensuring stable and high-quality polishing results.
