NANOTOL® — for highest precision
of the linear guideways
With the NANOTOL® technology, Röders has raised the precision and running behaviour of the guideways in the linear axes of the RPT machines to a new level. The tolerances in the running behaviour of the axis carriages are so small that they no longer have any influence on the machining result because other parameters such as the running concentricity of the tool etc. play a greater role. The diagram shows the significant difference between the previous and new guideway technology with NANOTOL®.
Residual errors in the straightness of the guideways and positioning uncertainties of the optical scale are measured over the entire travel of the axis with the high-precision XM60 laser from Renishaw and compensated for by the NC control system. In this way, exceptional accuracy and straightness of the linear axes are achieved.
