For this configuration, the ends of the guideways are precision ground. The offset between the individual guideways should not exceed 0.002 mm. Take note of the numbered guideways at the butt joints during installation. 8.3 Push Force Defined (VD) Demanding applications may only be possible if the guideway has a defined push force. These parameters can be defined by SCHNEEBERGER according to customer specifications. Carriages and guideways are then matched and delivered as a set. 8.4 Height-matched Carriages (HA) In accuracy class G1, the maximum height deviation of the carriages is ±10 µm. This tolerance can be too large for certain configurations, for example when the distances among the individual carriages are too small, i.e. when the carriage spacing L b is smaller than the carriage length L. In such cases, the tolerances can be reduced on a customer-specific basis. Multi-part guideways are numbered at the butt joint L = Length of the (longer) carriage in mm L b = Carriage spacing in mm
