The invention relates to a grinding machine for all kinds of material, the machine comprising: a receiving element for the material ( 5 ); at least one shaft ( 2 ) positioned in the housing ( 1 ) and provided with grinding tools ( 3 ); rigid cutting tools ( 4 ) which are arranged in the housing ( 1 ) and against which the grinding tools ( 3 ) operate, grinding the material ( 5 ) with specifically low forces. To this end, the grinding tools ( 3 ) comprise cutting regions ( 3.1,3.2 ) within which an inner cutting region ( 3.1 ) can take a large amount of material ( 5 ) to be ground and grind the same, thus comprising a small lever arm, and an outer cutting region ( 3.2 ) can take a smaller amount of material ( 5 ) to be ground and grind the same, thus comprising a large lever arm. According to the invention, the rigid cutting tools ( 4 ) are provided with teeth ( 4.2 ) having profiles ( 4.3 ) which cooperate with one of the cutting regions ( 3.1, 3.2 ), a first transversal edge ( 3.4 ) of the grinding tools ( 3 ) being oriented towards a second transversal edge ( 4.4 ) of a tooth ( 4.2 ) of the rigid cutting tools ( 4 ) in such a way that it cuts past the same.
