This paper describes the results of developmental research on the new porous diamond wheels based on the aluminium alloys. Structual features of the new wheel include various aluminide compounds (Ti/Al or Fe/Al phase) as a part of bond matrix and soluble-type compounds (Na_2S0_4,MgS0_4) as a pore formative substance. The results obtained are as follows : (1) The porous aluminium wheel containing a Ti/Al phase and Na_2S0_4-compound showed the intermediate performance between the usual metal bonded wheel and resin bonded wheel. (2) In comparison with the consumed power or the tangential grinding force, the porous wheel showed superior performance compared with the poreless diamond wheel. (3) Wear loss of the porous Ti/Al-wheel with MgS0_4 compound is smaller than the Na_2S0_4-wheel, but it has no recognizable effect in the Fe/Al-wheel. (4) Wear loss of the Ti/Al-wheel containing the tough-particles belongs to the G 5-group is very smaller, and the stock removal rate is doubled comparing with the G 2-wheel.
