By using Finite Element Methods ( FEM ), optimal reinforced ribbings are directly casted into the one-piece bed and column structure. Mechanical rigidity has been increased by 30% when compared to conventional designs. The GV-780 series is capable of performing heavy-duty turning and maintain long-term high-precision accuracy. More rigidity also means extended tool life.
Built to withstand years and years of rigorous high production turning, the heavily ribbed, one-piece thermally balanced bed and column casting components are of " MEEHANITE " casting.
X & Z axes uses high rigidity roller linear guideways which provides rigidity for heavy cutting and fast movement low abrasion advantages. The rigidity and controllability are greatly increased.
The servo motor of each axis feed system uses FANUC αi series components to ensure peak machining performance and accuracy.
Contact surfaces on the bed and column are precision hand scraped to provide maximum assembly accuracy, structural rigidity and load distribution.
