Abstract: An inner cam has a substantially C-shaped cross section, an arcuately shaped inner circumferential surface of which is ground with high precision by such a honing method. The inner circumferential surface has a discontinuous portion. The honing method includes a fixing step and a grinding step. A plurality of inner cams, in which openings are provided between both ends thereof in the circumferential direction, are stacked, and the arcuately shaped inner circumferential surfaces thereof are subjected to grinding. In the fixing step, the relative positions of the plurality of inner cams are fixed such that a resultant force against the inner cams arranged on both end sides in the stacking direction, and a resultant force against the inner cams arranged on a central side in the stacking direction are opposed to each other mutually at a center location of the stacking direction.

Abstract: An apparatus and method for surface finishing a workpiece is disclosed as including a workpiece supporting mechanism supporting a workpiece having a target shaped periphery with a given width to be surface finished and a tool holder holding a surface finish tool in abutting contact with the target shaped periphery of the workpiece. A pressure applying mechanism is operative to apply a pressure force to the surface finish tool through the tool holder to cause the surface finish tool to be held in pressured contact with the target shaped periphery, with the pressure force exhibiting a given distribution pattern depending upon an axial direction of the workpiece. A drive mechanism rotates the workpiece to allow the surface finish tool to surface finish the target shaped periphery into a given geometrical profile, variably contoured along an axis of the workpiece depending on the given pressure distribution pattern.

Abstract: A spindle for a grinding wheel which is to grind re-entrant cams on camshafts is described, comprising a drive motor, a shaft extending from the motor at the end of which is mounted a grinding wheel, and a rigid elongate casing extending from the motor and encasing the shaft. The length of the shaft and casing is selected to be at least as long as the axial length of cam shafts to be ground by the wheel. The shaft is carried in three hydrostatic bearings. One bearing is located near the grinding wheel at the end of the rigid casing remote from the motor. The assembly increases the shaft stiffness and its resistance to bending. A second bearing is located at the inboard end of the shaft and the third bearing is located within the motor at the far end of the shaft. The length of the rotor-bearing part is shorter than the external part of the shaft, which is constructed so that the stiffness and the support of the shorter part of the shaft dictate that the bending resonance of the longer external part is above the critical spindle rotational frequency. The motor housing is symmetrical and includes a water cooling jacket in which water follows a helical path around the motor, to avoid cooling one side of the motor more than another. The spindle is constructed to be axisymmetrical, so that any heat generated within the bearings dissipates radially and uniformly into the surrounding material. Oil is supplied under pressure to the bearings by a pump from a reservoir to which oil returns from the bearings. The oil is heated in each bearing and the heated oil drains into lower regions of the enclosure formed by the shaft casing and motor housing. The lower regions of this enclosure constitute a separate oil collection box mounted so as not to strain the shaft. A thermal barrier is provided between the upper and lower regions of the enclosure. During assembly the internal bores of two of the bearings are initially aligned and the third bearing is adjusted radially to bring all three bores into alignment.
