Cut-off Wheels

Struers cut-off wheels have been specially developed for materialographic specimen preparation: they produce specimens that are in perfect condition for the next preparation step. Our large range of different wheels assures that all materials can be cut without structural changes due to overheating or deformation, and guarantees maximum life time of the wheels. With cut-off wheels from Struers the abrasive density varies across the wheel radius – with increasing density towards the center of the wheel. This means that the cutting performance of the wheel remains constant even as it wears to a smaller diameter. As a conventional cut-off wheel with uniform abrasive density wears, the cutting performance changes from the outside to the inside. The number of grains is reduced, the load of each grain increases and the wheel appears to get softer and softer. The drawback is higher wear and a less controllable cut.
