High Rigidity Structure

Built to endure years and years of rigorous high production turning, the heavily ribbed, thermally balanced, high-rigidity bed and column are of Meehanite casting. It is capable of withstanding much greater stress without deforming and provides maximum vibration dampening, which result in a machine that will outlast and outperform the competition.
By using Finite Element Methods ( FEM ), optimal reinforce ribbings are directly cast into the bed and column structure. Mechanical rigidity has been increased by more than 30% when compared to conventional designs. The GV-1 series is capable of performing super heavy-duty turning and maintain long-term super high-precision accuracy. More rigidity also means extended tool life.
Spindle and servo motors of each axis rapid systems are FANUC αi series components to ensure peak machining performance and accuracy.
Casting structure of GV-1600M Series Shown
Extremely rigid crossrail is designed with box-shaped structure to prevent thermal displacement and assure machine stability during turning operations.
Crossrail can be moved up and down as desired to meet your requirements. W-axis travel is up to 800 mm ( 31.4" ) for better machining flexibility.
Pretension on all ground ball screws with extra wide ground box ways provide high rigidity for heavy-duty cutting.
Casting struction of GV-800 series shown Crossrail
Crossrail is mounted with 4 sets of up/down-positioning mechanism providing strong locking-positioning at each point which strengthens the overall rigidity of the crossrail and tooling spindle, thus assuring high accuracy for these series.
High-Low box way
The column is adopted with the high-low box way design to firmly support the crossrail while minimizing structural distortion and increasing rigidity.
X / Z axes slide ways are bonded with “ Turcite B ” to eliminate stick-slip, minimize wear and maintain long term accuracy.
