No blind spots in burr removal: copper tubes, valves and fittings — including small inner holes, gaps and threads — can all be polished, removing burrs from stamping and cutting.
Workpiece precision is not affected: parts suffer no dents or deformation, the dimensions of refrigeration components remain unchanged, and the accuracy of sealing surfaces is guaranteed.
High efficiency: batch processing handles multiple parts at one time, greatly reducing manual grinding costs.
Smooth and uniform surfaces: parts gain higher surface finish, which lowers pipeline resistance and reduces later oxidation.
Simple operation: no skilled technician is required, consumable loss is low, and cleaning and polishing are completed in one step.
