The grinding of the base is one of the maintenance works that must be periodically carried out to maintain the perfect efficiency of the skis.
Normal wear due to friction wears the insole slowly and progressively, it is invisible in the initial stages. This wear is concentrated near the edges, in the area of greatest pressure or in the area under the bindings. This type of wear causes the base to lose its flatness, which gradually becomes "rounded." The base of a medium-high level ski always has a footprint, that is a series of small notches with a depth of 50 microns (5 thousandths of a millimeter, or 0.5 tenths of a millimeter), arranged in such a way as to generate a drawing / imprint.
When the "cancellation" of the impression occurs, the base must certainly be rectified.
Our SKI SERVICE will grind your ski with the WINTERSTEIGER stone grinding machine that allows you to accurately level the ski and recreate the footprint.
