The present invention relates to several systems and methods for clamping, machining, inspecting, and/or correcting workpieces in an integrated machine.

A manufacturing apparatus for producing a curved contour on an end face of a roll includes a grinding device and a holding device, linearly movable relative to the grinding device. The grinding device is for grinding the curved contour on the end face. The holding device is for holding the roll between the holding device and the grinding device. A method for producing the curved contour on the end face using the manufacturing apparatus is also disclosed. The method includes driving the holding device to move in a linear fashion relative to the grinding device.

A system for polishing an outer surface of a specimen, the system including a motor and a rotatable shaft extending from a first end of the motor, wherein the specimen is removably attachable to the rotatable shaft, a safety cover configured to at least partially surround at least a portion of the rotatable shaft, wherein the safety cover includes a top panel, a first side panel and a second side panel spaced from each other across a width of the safety cover and extending downwardly from the top panel, and at least one aperture extending through at least one of the first and second side panels. The system further includes an abrasive material insertable through the at least one aperture so that the abrasive material is positionable to contact the outer surface of the specimen.

A grinding machine for machining workpieces includes a workpiece headstock and two grinding headstocks. A first grinding headstock has two grinding spindles each with one grinding wheel for grinding first and second planar and non-planar external surfaces. A second grinding headstock has a grinding spindle having a grinding wheel for grinding a central bore in the workpiece, and a clamping device to clamp the workpiece. First, the bore and the first planar and any non-planar external surface are ground on one side of the workpiece. Then, the workpiece is clamped in the bore. The second planar external surface can then be ground in the same grinding machine with one of the grinding wheels of the first headstock. The clamping device attached to the second grinding headstock is such that the central axis of the clamping device is exactly aligned with the central axis of the workpiece headstock.

A method for manufacturing a rotor includes the following operations: the clamping of a workpiece in a grinding machine; the performance of one or more cylindrical grinding operations whereby a rotor shaft section is ground to the desired diameter with a cylindrical grinding disk; the performance of one more profile grinding operations whereby a rotor body is profiled with a profile grinding disk. During the manufacture of the rotor in the grinding machine, the workpiece is not undamped and the cylindrical grinding operations and the profile grinding operations are done with the same grinding machine.
