Overview
High-Speed CNC Vertical Turning Centers
The GV-780 series is engineered for high-speed vertical turning where rigidity and cycle efficiency must come together in a compact machine layout. It targets large workpieces that benefit from vertical workholding stability and fast chip evacuation.
With a maximum swing diameter of Ø850 mm, maximum turning diameter of Ø820 mm, and 660 mm turning length, GV-780 covers a broad range of large-part turning requirements while keeping the setup accessible and production-focused.
A belt-drive spindle (up to 2,000 rpm) paired with a fast servo indexing turret supports efficient roughing-to-finishing workflows. Rapid traverses of 20 m/min on both X and Z help reduce positioning time on repeated cycles.
For higher part complexity, the platform can be configured with a live tooling turret, enabling additional operations beyond turning within the same setup—supporting shorter lead times and fewer handling steps.

Applications
General machining
Mixed prototype and production work across sizes; flexible envelopes and quick changeovers speed setups, reduce handling, and keep output consistent day to day.
Capital goods
Industrial equipment components from plates and frames to precision shafts and housings; scalable platforms and stable processes preserve accuracy over long runs.
Automotive
Tooling and production parts across the supply chain, from fixtures and dies to turned and milled components; repeatable referencing supports surface quality and tight tolerances.
Energy
Pump and valve components, compressor parts, and auxiliary housings; controlled cutting and chip/coolant management help protect tolerances, surface finish, and tool life.
Oil & Gas
Valve bodies, manifolds, housings, and high-integrity flanges; robust machining strategies and chip/coolant control help maintain tolerances in demanding alloys.
Railway
Frames, brackets, axlebox housings, and brake components; rigid machining and effective chip evacuation keep geometry and flatness consistent on large parts.
