Double Column Grinding Machine-GP Series
GP
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.

FEATURES
Crossrail Movable Type
- The ruggedly constructed beam provides a solid support for the horizontal and vertical grinding heads, resulting in outstanding stability during grinding operations.
- The grinding head movement (Y-axis) is individually driven by a servo motor and transmitted through a precision ball screw for high positioning accuracy.
