Overview
GV-780 CNC Vertical Turning Center
GV-780 provides a vertical machining layout for large chuck components. Its Ø850 mm swing, Ø820 mm turning diameter and 660 mm turning height accommodate a range of disc-shaped and cylindrical parts. Chuck sizes of 15″ and 18″ are available according to the selected configuration.
The machine combines a rigid cast structure with roller linear guideways on the X and Z axes. Travels of 500 mm and 670 mm respectively provide tool access across the working envelope, while rapid traverse of 20 m/min on each axis helps reduce positioning time.
The main spindle delivers 18.5 kW continuously and 22 kW for 30 minutes, with corresponding torque ratings of 620 Nm and 1,050 Nm. An 8- or 12-station servo-indexing turret supports the selected turning tool layout.
The M configuration adds a 12-station live tooling turret and C-axis control for parts requiring additional milling, drilling or tapping. Optional dual-face turning holders support simultaneous machining of opposing faces, while the optional Work-piece Balancing Analyzer (WBA) adds workpiece balancing analysis.
Key Features – GV-780 Series
Ø820 mm Turning Capacity
A maximum turning diameter of Ø820 mm and turning height of 660 mm support a broad range of chuck components.
High-Torque Main Spindle
The spindle provides 620 Nm continuously and 1,050 Nm for 30 minutes, supporting demanding turning operations.
Roller Guideways and Fast Positioning
Roller linear guideways on both axes combine with 20 m/min rapid traverse for efficient movement between cuts.
Optional Live Tooling and C-Axis
A 12-station live tooling turret and C-axis control allow turning and secondary machining operations within the same setup.

Notes
- Maximum swing diameter, turning diameter and turning height describe different limits of the working envelope. Usable capacity also depends on the chuck, jaws, tools and workpiece geometry.
- The 18.5/22 kW power and 620/1,050 Nm torque values refer to continuous and 30-minute ratings respectively.
- Chuck size and turret layout depend on the selected configuration. OD tool shank sizes differ between the 8- and 12-station turrets.
- Live tooling and C-axis control are optional. The listed tool spindle speed ranges apply to the live tooling system, and its motor and speed specifications depend on the selected configuration.
- Dual-face turning holders and WBA are optional. Tooling suitability depends on the component geometry and machining process.
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.
