Abstract

There is described a tool as well as a method for machining a workpiece made of a hard material by means of a geometrically determined blade. In order to obtain an improved surface quality of the machined workpiece when machining such a hard and brittle material, a tool is provided which has a cutting angle of less than 10°. According to the associated machining method, rotational speeds exceeding 1300 rpm are used. There is further described a machine that is to be used in such a tool and is utilized in such a method.
