Large CNC Turning Center

Large CNC Turning Center is built for global manufacturers requiring high torque, heavy workpiece load capacity, and sustained dimensional stability. Designed to process large-diameter shafts, heavy flanges, long cylinders, and industrial rollers, this machine eliminates chatter and structural deflection during deep-cut, heavy-roughing operations across steel, stainless steel, alloy steel, and cast iron.

Enhanced Rigidity: Heavy-duty bed structure reduces chatter and dampens vibrations during heavy roughing.
Superior Low-Speed Torque: High-power spindle system optimizes material removal for tough alloys and forging parts.
Expanded Work Envelope: Accommodates turning diameters up to 1,600 mm and length options up to 6,000 mm.
Heavy Load Capacity: Designed to support multi-ton workpieces without structural deflection.
Customizable Configurations: Flexible choices of CNC controls, turrets, guide systems, and steady rests.

Oil & Gas Equipment: Valve bodies, drill collar threads, riser connectors.
Energy Machinery: Wind turbine rotor shafts, generator rotors, turbine casings.
Shipbuilding & Marine: Propeller shafts, rudder stocks, stern tube bushings.
Heavy Machinery & Mining: Excavator pin shafts, crusher shafts, mill rollers.

Bed & Box Guideways: Hardened and ground box ways (Turcite-B coated) or high-load roller linear guideways ensure high rigidity, low friction, and long-term wear resistance.
Tailstock Assembly: Heavy-duty programmable or hydraulic tailstock with built-in live center for supporting heavy, long-shaft workpieces.
Tooling Systems: Heavy-duty 8/12-station hydraulic turret or servo turret accepting large shank tooling (32x32 mm or larger) for high-force cutting.

CNC Control Integration: Pre-configured with industrial-grade controllers featuring dynamic graphics, custom macros, and pitch error compensation.

To select the correct machine configuration, consider the following workpiece parameters:
Large Diameter Turning: Select larger swing capacity and wider bedway spacing.
Heavy Workpiece Weight: Choose hardened box guideways, tailstock, and reinforced bed structure.
Long Shaft Machining: Extend Z-axis travel and integrate hydraulic steady rests (closed/open type).
High-Volume Production: Add live tooling, automatic chip conveyors, and in-process probes.

Spindle Upgrades: Live tooling turret (C-axis) for milling/drilling operations.
Workholding: 3-jaw/4-jaw manual chucks, heavy-duty hydraulic chucks, custom faceplate fixtures.
Auxiliary Equipment:
Hydraulic auto-centering steady rest
Automatic chain-type chip conveyor
Tool setting probe
High-pressure coolant system (20–70 bar)

12-month global warranty on main components.
English technical documentation, wiring diagrams, and manual sets.
Remote PLC diagnosis and online technical assistance within 24 hours.
On-site commissioning and operator training available upon request.
