Soft-Consolidation Abrasives Pneumatic Wheel Technology Oriented to Finishing of High-Hardness Free-Form Surface


Article Preview

In order to improve the efficiency of high-hardness laser strengthening mold polishing, especially to the free-form surface, a new precision finishing method based on soft-consolidation abrasives pneumatic wheel is brought forward. The pneumatic wheel is constituded by flexible rubber maxtrix, combined with the robbet control. The abrasives group is bond to the rubber matrix by the polymer binder. In the way, compared with those free abrasives used in other polishing method, the soft-consolidation abrasives can get more stable surpport from nearby polymer to form effective cutting. On the other hand, it is unlike the abrasive of rigid grinding wheel because the flexibility of pneumatic wheel can have self-adaptation according to the changes in local curvature and achieve large scale copying contact between tools and work piece. Combined with the lay elastic system theory and Preston equation and coefficients, the mechanics model of polishing is given. The results of experiment shows the Ra of workpiece can be reached to 0.09um and the efficiency of process can be improved three times more than free abrasive machining. It will show its wild prospects in the process of polishing.
