Abstract
A grinding method for single-disc cylindrical grinding of elongated objects, such as cylindrical paper machine rollers, in which method the object to be ground is rotated about its axis and a grinding stone is rotated and its position on the surface of the object being ground is adjusted so that the grinding point of the grinding stone is held substantially at a constant distance from the center axis of the object being ground regardless of the deflection of the object. In the method, the position of the grinding stone is adjusted by means of an oscillating positioning controller synchronized with the rotation of the roller and receiving feedback from a measured quantity that bears a linear correlation to the change of position of the surface being ground.

Grinding method in single-disc cylindrical grinding of elongated objects of substantially circular cross-section, such as paper machine rollers, in which method
- the object being ground is rotated about its axis, and
- a grinding stone is rotated and its position on the surface of the object being ground is adjusted so that the grinding point of the grinding stone is held substantially at a certain distance from the actual center axis of the object being ground regardless of the deflection of the object,
- characterized in chat
- the position of the grinding stone is adjusted by means of an oscillating positioning controller synchronized with the rotation of the roller and receiving feedback from a measured quantity that bears a linear correlation to the change of position of the surface being ground.
