J76B-600LU Gang Type CNC Lathe Machine for Larger Workpieces and Mold Steel Processing
The J76B-600LU gang type CNC lathe machine is designed for manufacturers that need larger turning capacity, strong spindle performance, and stable rough and finish machining for metal parts. With a maximum swing diameter of Ø600 mm, maximum turning diameter of Ø400 mm, maximum turning length of 560 mm, Ø86 mm spindle bore, and Ø72 mm maximum bar material diameter, this machine is suitable for stainless steel, titanium alloy, carbon steel, mold steel, and other industrial materials.
This model is especially suitable for specialized processing of mold steel up to 300 mm. For B2B buyers, machine rigidity, spindle torque, and long-term structural stability are critical when machining larger workpieces or harder materials. Weak machine structures may cause vibration, unstable surface finish, machining deviation, and shorter tool life. The J76B-600LU solves this problem with a one-piece casting base, slant bed structure, aging treatment process, Taiwan SYNTEC controller, reinforced feed axis structure, and stable servo system.
As a slant bed CNC lathe, the J76B-600LU is suitable for factories that need turning, facing, boring, threading, grooving, and precision metal machining in one machine. It is especially practical for mold steel processing factories, hydraulic component suppliers, automotive parts manufacturers, precision machining workshops, hardware processing factories, mold component workshops, and CNC turning service providers.
Key Features of the J76B-600LU
Ø400 mm Maximum Turning Diameter for Larger Workpieces
The J76B-600LU provides a Ø400 mm maximum turning diameter, making it suitable for larger workpieces than standard 600LU models. This gives factories more flexibility when processing mold steel parts, larger sleeves, discs, fixtures, hydraulic components, and industrial mechanical parts.
For buyers who need stronger capacity for large turned parts, this model offers a practical machining range while maintaining a compact machine layout.
Specialized Mold Steel Processing Capability
The J76B-600LU is designed for specialized processing of mold steel up to 300 mm. Its rigid one-piece casting base, slant bed structure, and stable spindle configuration help support rough and finish machining of harder materials.
This makes the machine suitable for mold component workshops, tooling manufacturers, and factories processing high-strength metal parts.
Ø86 mm Spindle Bore and Ø72 mm Bar Capacity
The machine features a Ø86 mm spindle bore and supports a maximum bar material diameter of Ø72 mm. This configuration is suitable for larger bar material processing, including large shaft parts, sleeves, hydraulic fittings, automotive components, and mechanical connectors.
The machine uses an A2-8 spindle nose, 10-inch hydraulic chuck, and maximum spindle speed of 2000 r/min for stable turning performance.
One-Piece Casting Base and Slant Bed Structure
The J76B-600LU adopts a one-piece casting base and slant bed design to maintain stable machine performance during long-term production. The integral casting undergoes aging processes such as annealing and vibration treatment to improve long-term stability and extend machine tool lifespan.
This rigid structure helps reduce vibration, improve cutting stability, and support consistent rough and finish machining.
Taiwan SYNTEC CNC Controller
The machine is equipped with a Taiwan SYNTEC 22TA CNC system with a 10.4-inch screen. The controller provides stable operation, convenient programming, and reliable control response for CNC turning production.
The SYNTEC system also includes G183 face drilling cycle support, helping improve machining flexibility for different part features.
15 kW Spindle Motor with High Torque Output
The standard spindle motor power is 15 kW with 143 Nm torque. An optional 15 kW / 192 Nm configuration is available for buyers who need stronger torque output for more demanding cutting conditions.
This torque configuration supports machining of stainless steel, titanium alloy, carbon steel, mold steel, and other materials that require stable cutting force.
125-8T Servo Turret for Heavy-Duty Machining
The J76B-600LU uses a 125-8T servo turret configuration, suitable for larger tools and heavy-duty turning applications. The turret supports multiple machining processes in one setup and helps improve production flexibility.
For factories machining larger or harder parts, the 125-8T turret provides better tool capacity for demanding operations.
Benefits for B2B Manufacturing Buyers
Larger Turning Capacity for Industrial Parts
With a Ø400 mm maximum turning diameter and 560 mm maximum turning length, the J76B-600LU is suitable for larger workpieces, mold steel parts, sleeves, discs, hydraulic components, and industrial fittings.
This helps manufacturers process more complex parts without frequently switching to larger machine models.
Stronger Structure for Mold Steel Machining
The machine is suitable for rough and finish machining of mold steel and other difficult materials. The rigid casting base, slant bed structure, high-torque spindle motor, and stable feed system help support consistent cutting performance.
Better Long-Term Stability
The one-piece casting base undergoes annealing, vibration aging, and other aging processes. This helps reduce structural deformation risk and maintain stable machining accuracy over long-term production.
For batch production workshops, long-term stability helps reduce rework, improve part consistency, and maintain delivery quality.
Larger Bar Processing Capacity
With a Ø86 mm spindle bore and Ø72 mm maximum bar material diameter, the machine is suitable for large bar material turning, shaft machining, sleeve machining, and hydraulic component production.
Flexible CNC System and Automation Options
The standard configuration includes a Taiwan SYNTEC CNC system. FANUC is available as an optional control system. Buyers can also choose optional accessories such as electric spindle, feeding device, chip conveyor, automated robot, oil mist separator, push-up chuck, and different feed axis options.
This makes the J76B-600LU suitable for both standard turning production and automated machining lines.
Reliable Components for Industrial Use
The main configuration includes Taiwan SYNTEC system, Taiwan SYNTEC or Japan YASKAWA servo system, Taiwan PMI or HIWIN C3-grade ball screws, Taiwan PMI or HIWIN P-class linear guides, Taiwan POSA spindle or Kenturn A2-8 spindle depending on configuration, Schneider electrical components, Japan HERG lubrication pump, and a customized hydraulic station.
These components help support stable industrial operation, easier maintenance, and long-term production reliability.
