High smoothness grinding of aluminum alloy with surface traverse grinding

High smoothness machining of aluminum alloy has been increasingly becoming important. Generally aluminum alloy is finished smoothly by cutting with diamond tool. High smoothness grinding of aluminum alloy, however, has been strongly desired because of the difficulty of re-sharpening of diamond tool. In the report, the influence of surface traverse grinding conditions on high smoothness grinding of aluminum alloy is examined by the comparisons of the dressing and grinding characteristics. The experiment are executed using the resinoid bonded diamond wheel of coarse grain size and two types of grinding fluids which are the two kinds of emulsion type, that is, the conventional emulsion type and the special emulsion type including the extreme pressure additives. From the results it is found that the characteristic obtained by using the special emulsion type is much better than the conventional emulsion type.
