Better end product quality from reduced MD and CD variation

Accurate Valmet 3D roll grinding

At Valmet, grinding targets are customized according to each customer's specific requirements using advanced 3D measurement technology. Whenever possible, Valmet grinds the rolls with their roll bearings on the roll axis. This allows 3D measurement of the roll in its actual running condition.

Valmet's 3D measurement system is capable of measuring the precise roundness profile of a roll. Connecting it to a grinding head with 3D compensation allows almost perfect roundness to be achieved.

Using precise 3D measurement of the roll shape, the running time can be
linked to the grinding quality of the roll. This also means the planned shutdown interval is achieved with a safe vibration level.

Valmet's roll grinding services provide precise profile and roundness shapes for roll and cylinder surfaces.
