STIER Project Case | Efficient Grinding of Weld Scars on Battery Boxes

STIER uses the PolishX axial flexible force control device together with a flexible grinding robot to grind weld scars on battery boxes. The minimum actual output force can be controlled down to 1 N, with force control accuracy of ±0.8 N and response under 10 ms. A positioner enables autonomous grinding across multiple areas and autonomous tool changing. In testing, weld scars were removed cleanly and R corners and edges transitioned smoothly, with a cycle time of no more than 100 s per piece and a first-pass yield of no less than 90%. The solution targets welded box-type workpieces in the automotive and new energy industries and supports process validation with customer-supplied parts.
