Abrégé

The invention relates to a profiled grinding tool (7) for rotatingly machining workpieces, in particular gearwheels and/or gears, comprising a main body, which has at least one device, in the form of a preferably hollow-cylindrical shaped region (6), for clamping onto a tool carrier, and comprising at least two axially spaced grinding segments (1, 3), which act in the peripheral direction, wherein the second grinding segment (3) has a modulus of elasticity which is lower than the modulus of elasticity of the first grinding segment (1). According to the invention, the main body is formed integrally with the first grinding segment (1), and the main body comprises, axially spaced apart from the first grinding segment (1), at least one support portion (2), to the periphery of which at least one second grinding segment (3) is permanently frictionally connected. The invention also relates to a method for producing a grinding tool according to the invention.

Abrégé

The invention relates to a method for producing a ceramic moulded body, comprising the following steps: a) producing a green body containing ceramic material, binding agents and an organic pore forming agent; b) heating the green body to a temperature equal to or higher than the sublimation temperature of the pore forming agent; c) burning the green body to form a ceramic moulded body. According to the invention that the organic pore forming agent is selected from the group consisting of dicarboxylic acids and mixtures of dicarboxylic acids, the sublimation temperature being at least 80 k lower than the decomposition temperature.
