These grinding-wheels are very suitable for the pre-burnishing of the hard pivots in the horology industry and the tools ‘manufacturing. Good results are also obtained in the finishing-burnishing. The roughness of the pivoting grinding-wheel is decisive for the obtained surface-finish, for the pivots and for the removed quantity of material. The roughness can be slightly changed by means of a straightening with diamond grinding-wheel with different grains. An increasing roughness of the pivoting grinding-wheel implies an increasing roughness of the pivot after the pivoting, as well as a shorter correction time.
The sharpening of the grinding-wheel must be done on the runner, so that the grinding-wheel will continue to turn perfectly round.
