Of thoseLM rails, the one marked with "KB" after theserial number is the master LM rail. The LMblock on the master LM rail has its referencesurface finished to a designated accuracy,allowing it to serve as the positioning referencefor the table. (See Fig.20.)LM Guides of normal grade are not marked with"KB." Therefore, any one of the LM rails havingthe same serial number can be used as themaster LM rail.[Markings on the Reference Surface]In the LM Guide, the reference surface of theLM block is opposite the surface marked withthe THK logo, and that of the LM rail is on thesurface marked with a line (see Fig.21).
