Machining Time Required For Taper Grinding and Its Cost
Fig 6 shows a rough idea of fixture used for tapper grindingG17 grinding machine have a grinding wheel of width 65mm.If this type of arrangement is there the portion to be grinded will be parallel to the wheel so that proper grinding can be carried out. Tapper angle calculation Large diameter (D) =55mm Smaller diameter (d) =45mmCenterless Grinding Not Magic! Modern Machine Shop,Instead of grinding a lobe shape in the workpiece, the high spot is gradually reduced by the action of the grinding wheel. So rather than creating a low spot on the periphery of the work equal to the high spot, the grinding wheel generates a proportionally smaller low spot at its contact with the workpiece.
