    Beam Clamping
    • The beam is clamped securely by hydraulic force in combination with the use of dise springs. This fully prewents the beam from slipping down to eliminate any loss in grinding accuracy.
    Beam Elevation
    • The beam elevation is driven by an inverter controlled motor that drives a connecting shaft to transmit the two elevation gcrews at the left and right sides. This elevation driving system allows the beam to clovate synchronously at both ends, so as to ensure outstanding leveling accuracy of the beam.
    Double Hydraulic Cylinders' Counter-balance
    • The beam elewation (Z-axis) is counters balanced by two hydraulic cylinders, enguring exceptionally smooth motion sand the best travel accuracy.
    Horizontal Grinding Head (Standard)
    • The Top-One GL series Double Column Surface Grinding Machine can be mounted with a horizontal grinding head and a vertical grinding head, allowing surface grinding and angular grinding to be accomplished at a time. With both grinding heads, the increased grinding accuracy and afficiency can be achieved.
