Abstract: In a method for grinding coffee beans (5), the beans (5) are ground off bit by bit by applying a device (1) comprising two tools (20; 40, 42), wherein one of the tools (20; 40, 42) is a grinding tool (20) having an abrasive surface (21), wherein the beans (5) and the abrasive surface (21) are made to contact each other and to perform a relative movement with respect to each other, and wherein another of the tools (20; 40, 42) is a bean delimiting tool (40, 42) having a surface (44) against which the beans (5) are retained during the time that they are in contact with the abrasive surface (21). By grinding off coffee beans (5) instead of crushing coffee beans (5) in a conventional manner, it is achieved that the grinding process can be performed at a relatively high speed and a relatively low torque.
