Conventionally, grinding of stainless steel, aluminium ally, copper alloy, and titanum alloy are difficult to obtain the high quality finish, because they have the mechanical properties such as low hardness, high toughness which result in the loading of wheel and the poor surface finish. Inorder to perform the grinding operations for these sorts of materials easily, the discontinuous grinding wheel with multi-porous grooves has newly been developed. The multi-porous grooves were formed during wheel production. This discontinous grinding wheel increases the grinding performance. It is desirable to use the discontinuous grinding wheel when grinding materials wiht high efficiency and accuracy which is impossible by conventional wheels. In this paper, the constructing and manufacturing method of grinding wheel with multi-proous grooves are explained, and the grinding charateristics of discontinuous grinding wheel are also illustrate.

Recently, emerging as major tasks are grobal warming prevention, and earth environment conservation and preservation, and the resolution of environmental issues is crucial in the 21st century and needs to jointly be tackled by all nations in cooperation with each other. This research developed dry cold air grinding system, and this ensured cold effects of machine tools and dressing effects against loading phenomenon of grinding wheel, thus extending the tool life of grinding wheel.
