A novel sandwich structured wheel to achieve mirror finish in grinding of a mould steel

Abstract A novel manufacturing tool called sandwich flexible elastic grinding wheel is developed to achieve high material removal rates and machined finish of a mould steel. This made aluminium matrix, ethylene propylene rubber layer abrasive layer. Ethylene has great elasticity produces deformation when contacting with the workpiece. With existence an layer, rigidity at small scales allows occur, which can effectively remove residual height surface improve quality. In this paper, influences process parameters on key characterisation integrity are studied, roughness under various investigated. Then, that suitable for mirror machining selected by experiments demonstrated S136 steel Mirror be achieved single processing. The converges from original Ra142 nm Ra7.42 nm, texture more compact regular, significantly improved.
