Apparatus suitable for the assessment of lubricants for the slides of machine tools, comprises a fixed slide carrier block, a moving slide block, and a drive block moving parallel to the slides at constant speed, under the action of a motor. The drive block carries a bracket with a lever which makes it possible to load the moving slide block and has a compressible elastic element to push the moving slide block. A comparator dial and an electric displacement sensor are connected to a recorder, so as to display and record the relative movements of the fixed and moving slide blocks.
