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 grounded 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 using 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.

Abstract: An ultrasonic testing method uses surface waves to prevent false detection of primary cracks, to lower the level of structural noises from grain boundaries, and to improve the detectability in the ultrasonic testing by surface wave testing of hot rolling rolls. A surface wave probe 10 capable of transmitting and receiving a surface wave is provided with a piezoelectric element 10A, a resin wedge 10C disposed on the front surface of the piezoelectric element 10A and a damping block 10B disposed on the back surface. The surface wave probe 10 is driven to produce a short pulse having a pulse length being at most 2.5 times the wavelength of the surface wave to be produced. A coupling liquid medium is supplied to the probe 10 in accordance with the peripheral speed of the roll to be tested. Depending on the height of the reflected waves measured, the grinding allowance of the roll is determined, and the roll is ground according to the thus-determined grinding allowance. The roll may be tested while being partly ground, and the optimum grinding allowance of the roll may be determined.

Abstract: A grinding head unit is constituted by a grinding wheel, a drive device for rotating the grinding wheel, and a movement device for moving the grinding wheel. When vibration of a mill roll is applied to the grinding wheel, a plain wheel integral with an abrasive layer of the grinding wheel and having an elastically deforming function is deflected to absorb the vibration energy. The contact force between the abrasive layer and the mill roll is measured for determining a profile of the mill roll. The mill roll can be thereby ground into a target profile while absorbing the vibration transmitted from the mill roll and measuring the profile of the mill roll, without causing any chattering marks.

Abstract: Disclosed is a method of manufacturing a spindle motor using a fluid bearing. The spindle motor includes a hub having a support member for supporting a disk storage medium and a magnet, a fixed member having a coil, for holding the hub rotatably, and a fluid bearing provided between the hub and the fixed member. In this method, the hub is secured to the fixed member through the fluid bearing. This method includes a step of grinding a support surface of the support member. In this grinding step, a grinding member is applied to a part of the support member, and other part of the support member is pressurized by a pressurizing member to prevent the hub from falling down due to the pressurization by the grinding member.

Abstract: A process for regrinding the rolls installed in hot-strip roll stands using rotating pot-shaped grinding tools which are movable in an oscillating manner parallel to the roll axis. The grinding tool is fastened to the end of a grinding shaft which is driven in rotation so as to be axially displaceable transversely to the roll, guided coaxially in a grinding sleeve and connected at its opposite end with a displacing drive supported directly at the housing. The contact pressing force of the grinding tools at the roll is applied by compressed air which is supplied to the displacing drives. The air pressure, which is preset corresponding to the desired contact pressing force, is changed within a narrow range until the torques of all grinding tools or of one of the grinding tools measured at the drive motors for the grinding tools which are driven in rotation are identical and constant.
