Abstract: An on-car brake lathe is provided with a runout compensation system configured to monitor the rotational position of a pair of slant discs within an aligning joint of the on-car brake lathe. The system monitors the amount of runout present between the rotating components of the on-car brake lathe and the wheel hub to which the on-car brake lathe is secured. The system calculates the appropriate rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis in order to align the on-car brake lathe with the rotational axis of the wheel hub. Finally, an adjustment mechanism is activated to rotationally drive each slant disc directly to the calculated rotational position with a minimum amount of rotational movement based on the current rotational position of each slant disc and the required calculated rotational positions.

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: A rotary die cuter for a box making machine has an abrading cylinder mounted for rotation alongside the anvil for engaging and resurfacing the blanket of the anvil on a virtually continuous basis to smooth, level and even the surface of the blanket. This resurfacing occurs during normal operation of the rotary die cutter so no production is lost. The abrading cylinder has a sheet layer of abrasive material spirally wrapped on the surface of the cylinder and bonded thereto with adhesive material on the backside of the sheet layer. The abrading cylinder is movable towards or away from the anvil by a servo motor and gearbox. The position of the abrading cylinder relative to the anvil is determined by an encoder which sends the information to a computer or programmable controller which calculates the changing diameter of the blanket and the amount of speed change that must be imparted to the anvil to compensate for its changing diameter.
