Longitudinal Slideways Cross Slideways Longitudinal Movement Cross Movement Vertical Downfeed Auto Down Feed
Double Vee Ways Flat Doveail Type Gibbed Ways Hydrulic Automatic Rapid Up/Down Optional
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).
