Abstract (en)
[origin: EP0078472A2] A machine for reconditioning the points of twist drills is described comprising a grindstone (3), a drill holder (13) and supports for the latter, said supports being carried on a platen (7) which platen is movable in a horizontal plane towards and away from the grindstone (3), the said platen (7) being further supported on an inclined surface (5) of a member (4) which latter is adapted to be moved so that the place of support of the platen (7) on such inclined surface (5) is at a higher or lower level of the said inclined surface (5). With such a structure it is possible to semplify the position changing steps and to dispence with dismounting of the support and/or holder, since the whole change can be attained by a simple switch-over of a lever.
