The invention relates to a portable edging machine for spectacle lenses, having a conical grinding wheel arranged on a shaft mounted horizontally in the base body. It is characterized in that the grinding-wheel shaft (6) encloses an angle ( alpha ) with the base body longitudinal axis and the axis of rotation of the lens which corresponds to half the cone angle of the grinding wheel (11), and a lens-holding part (17) in front of the grinding wheel (11), carrying a lens-holding shaft (18, 22) divided in two, can be manually displaced along an axis situated parallel to the longitudinal axis of the base body and can be pivoted in such a way that the spectacle lens circumferential portion to be ground is pivoted into the horizontal plane, or approximately into this plane, which runs through the grinding-wheel shaft (6). <IMAGE>
