    Straightness of table movement in longitudinal direction 0.02mm/m.
    Straightness of table movement in transverse direction 0.02mm/m.
    The surfaces of longitudinal table ways are all hand scraped to getting perfect contact pattern
    and to ensure very high accuracy.
    Longitudinal table ways are designed to have slide surfaces longer than that of the working surface and equal to the table length to keep the table free from torsion and deflection(except PSGS series).
