A method of machining a disk for a toroidal-type continuously variable transmission, has the steps of fixing a disk to a core bar having a pair of reference portions for rotation at both end thereof, clamping the reference portions by a first center and a second center opposing the first center, abutting a first flat surface portion formed on one side surface of the disk against a reference for axial abutment, machining a first traction surface formed on another side surface of the disk, inverting the disk with the disk fixed to the core bar, clamping the pair of reference portions by the first center and the second center, abutting a second flat surface portion formed on the other side surface of the disk against the reference for axial abutment and machining a second traction surface formed on the one side surface of the disk.
