摘要： A method of grinding workpieces of aluminium alloys to achieve high surface quality, where the workpiece is machined in an environment comprising a semi-synthetic liquid with a concentration of 3 to 7%, by a grinding wheel with the grain of green silicon carbide of a size smaller than 200μm, in a bonding agent consisting of synthetic resin, at a circumferential speed of the workpiece in the range of 20 to 30 m-min
-1 , where the cutting speed of the grinding wheel is in the range of 35 to 40 m.s
-1 , the radial feed rate during plunge grinding is between 0.07 to 0.13 mm-min
-1 or the longitudinal axial feed raters between 0.01 to 0.04 m.min
-1 .
