With a massive and rigid construction, the GP series double column surface grinding machine from Top-One is designed and built for precision grinding for extra-large work pieces. This series of machine is equipped with a horizontal grinding head as standard equipment, and a vertical wheel head is available upon request. High precision Z-axis downfeed can reach 2 µm, which will fully meet high accuracy grinding requirements.
