摘要： A wave cam is rotatably and integrally mounted on a drive shaft of a compressor. Pistons are connected to cam surfaces of the wave cam via shoes. The shoes move relatively to the cam surface along a predetermined orbital path. The predetermined orbital path defined on the cam surfaces is ground by bringing a grinding surface of a grinding stone, attached to a rotary shaft, into contact with the cam surfaces. During grinding, the grinding surface is perpendicular in respect with the cam surface. The axis of the grinding stone coincides with the axis of the rotary shaft.

摘要： A grinding apparatus grinds a workpiece by rotating the workpiece held by main spindles and a grinding wheel held by a wheel spindle, and by relatively moving the grinding wheel toward and away from the workpiece. The grinding apparatus includes a first detection unit that detects a rotational phase of the workpiece; a second detection unit that detects a grinding resistance moment at a grinding point between the grinding wheel and the workpiece, or detects a drive current of a rotary drive unit of the workpiece or a rotary drive unit of the grinding wheel; a storage unit that stores the grinding resistance moment or the drive current in a manner associated with the rotational phase; and a determination unit that determines a slip between the workpiece and the main spindles based on the grinding resistance moment or the drive current at a current rotational phase, and on the grinding resistance moment or the drive current at the same phase as the current rotational phase of a previous time.

摘要： A grinder performs operations ranging from rough grinding to mirror-like finishing of the whole of an elongate peripheral surface of a work rotated around the central longitudinal axis thereof by pressing a grindstone to the work and by shifting the grindstone along the longitudinal direction of the central rotary axis of the work. By providing a rotor on the carriage adapted to move in parallel with the longitudinal axis of the work to be ground and by fixing grindstones different from each other in grain size to a plurality of rotating shafts fixed to the rotor, respectively, a grindstone in desired grain size is, upon rotation of the rotor, selectively brought into contact with the work. The grindstone that has been in contact with the work is rotated by a drive and, at the same time, the pressing force to act upon the work is imparted to the grindstone by a presser. Thus, the work is ground throughout the elongate peripheral surface thereof with the grindstone being pressed thereagainst by the presser and being shifted therealong by the drive.
