To work, in particular to trim, round-arch frames or similar workpieces, it is proposed to fasten the work table to a vertical support designed as a column, to provide an extension-arm construction on the column head, which extension-arm construction is rotatable about the axis of the column and has a rail extending horizontally over the length of the construction and parallel to the horizontal extension arm, to arrange a travelling carriage on the horizontal rail, which travelling carriage is movable over the length of the extension arm, and to fasten a vertical support, pointing downwards, to the travelling carriage, which support accommodates the vertically adjustable tool unit. |
