Abstract: A half toroidal CVT disk having an inner surface portion, an outer surface portion and a toroidal surface having a given machining allowance is centered with said inner surface portion worked prior to the heat treatment of said half toroidal CVT disk as the standard thereof, and then is chucked by a chuck mechanism. The toroidal surface of the chucked half toroidal CVT disk is ground by a grinding mechanism with the grinding wheel for grinding the half toroidal CVT disk in a state that one of said half toroidal CVT disk and said tool is inclined at a given angle with respect to the other.

Abstract: An intersection between a first circular arc traced around a given measuring point on a toroidal surface on one side by the extreme end of a segment with a length equal to the curvature radius of traction surfaces of discs and a second circular arc traced around a given measuring point on a toroidal surface on the other side by the extreme end of the segment is obtained in a cross section along the central axis of the power roller. A plurality of intersections are obtained by repeating the process for obtaining the intersection for each of different measuring points on the toroidal surfaces. That specific one of the intersections which is situated nearest to the reference surface of the power roller is selected and it is concluded that the selected intersection is the tilting center of the discs.

Abstract: A grinding apparatus for grinding a spline ball groove on a workpiece comprises a rod-shaped grindstone, having a distal end portion with a curved surface corresponding to the groove to be ground, and a spindle mechanism for rotating the grindstone. The spindle mechanism and the grindstone are supported by means of a supporter in a manner such that they are inclined at a given angle to an axis of the workpiece. A rotary dresser, which has a dress groove corresponding to the curved surface of the distal end portion of the grindstones is disposed near the grinding apparatus. The grindstone can be reciprocated along the axis of the workpiece by a drive mechanism between the workpiece and the dresser without changing its angle of inclination.
