Overview
GS-4000 Series Heavy-Duty Turning Centers
The series provides two spindle-size configurations. GS-4000 accepts 15 / 18 in chucks and Ø115 mm bar stock, while GS-4300 offers 20 / 24 in chucks and Ø165 mm bar capacity.
A 30° slant bed and widely spaced, hardened box ways on the X and Z axes support the cutting assembly during demanding operations. This rigid foundation is suited to sustained stock removal and long machining cycles.
The main spindle delivers 30 kW continuously and 37 kW for 30 minutes through a two-speed gearbox. Spindle torque reaches up to 2,900 Nm, while servo-indexing turret configurations provide 12 or 10 tool stations.
Four bed lengths accommodate different workpiece lengths. Optional live tooling and C-axis control add milling, drilling and tapping; the Y-axis enables off-center features, and the sub-spindle supports machining the rear of the component.

Notes
- The listed turning lengths refer to a 15 in chuck. Usable machining length depends on the chuck and workholding arrangement.
- Configurations with Y-axis control have a maximum turning diameter of Ø460 mm and live tooling speeds up to 6,000 rpm.
- Live tooling, C-axis, Y-axis and sub-spindle equipment are optional. Sub-spindle configurations are available for selected bed lengths.
- Turret station count, tailstock type and center taper depend on the selected tooling and workpiece-support configuration.
- Spindle torque and working capacity may vary according to the selected machine configuration.
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.
Wind energy
Drivetrain and auxiliary components including hubs, seats, flanges, and structural parts; rigid setups and stable processes sustain accuracy, finish, and tool life across long runs.
Railway
Frames, brackets, axlebox housings, and brake components; rigid machining and effective chip evacuation keep geometry and flatness consistent on large parts.
Defense
Housings, carriers, and structural parts in high-strength alloys; stable machining conditions and verified datums deliver repeatable accuracy under heavy cuts.
