J76-600LU Gang Type CNC Lathe Machine for Large Bar and Medium-Length Turning
The J76-600LU gang type CNC lathe machine is designed for manufacturers that need larger swing capacity, stronger spindle bore capacity, and stable rough and finish machining for metal parts. With a maximum swing diameter of Ø600 mm, maximum turning diameter of Ø300 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.
For B2B buyers, spindle capacity, machine rigidity, and long-term stability are critical when processing larger bar materials and medium-length parts. In real machining environments, weak machine structures may cause vibration, unstable surface finish, machining deviation, and shorter tool life. The J76-600LU 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 J76-600LU is suitable for factories that need turning, facing, boring, threading, grooving, and precision metal machining in one machine. It is especially practical for hydraulic component suppliers, automotive parts manufacturers, precision machining workshops, hardware processing factories, mold component workshops, and CNC turning service providers.
Key Features of the J76-600LU
Ø600 mm Swing Diameter and 560 mm Turning Length
The J76-600LU provides a Ø600 mm maximum swing diameter and 560 mm maximum turning length, making it suitable for medium-length workpieces and larger turned components. This machining range gives factories more flexibility when processing shafts, sleeves, connectors, tooling parts, hydraulic components, and industrial mechanical parts.
Compared with shorter turning models, the J76-600LU supports longer workpiece machining while maintaining a compact machine layout.
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 to support stable turning performance for larger workpieces.
One-Piece Casting Base and Slant Bed Structure
The J76-600LU 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 Higher Torque Option
The standard spindle motor power is 15 kW with 95.5 Nm torque. An optional 15 kW / 143 Nm configuration is available for buyers who need stronger torque output for more demanding cutting conditions.
This makes the J76-600LU practical for machining stainless steel, titanium alloy, carbon steel, mold steel, and other materials that require stable cutting force.
100-12T Servo Turret for Multi-Process Machining
The standard turret configuration is a 100-12T servo turret, while a 125-8T turret is available as an optional configuration. This allows manufacturers to select a turret setup according to tool quantity, part complexity, and machining requirements.
The servo turret supports multiple machining processes in one setup and helps reduce manual tool changing.
Reinforced Feed Axis Structure
The J76-600LU offers a maximum fast travel speed of 24 m/min. The X/Z axis uses C3-grade ball screws and roller linear guides to support stable movement and accurate positioning.
The X-axis maximum travel is 230 mm, and the Z-axis maximum travel is 580 mm, providing enough stroke for medium-length turning applications.
Benefits for B2B Manufacturing Buyers
Larger Bar Processing Capacity
With a Ø86 mm spindle bore and Ø72 mm maximum bar material diameter, the J76-600LU is suitable for buyers who need to process larger bar materials than smaller spindle bore models.
This makes it practical for large shafts, sleeves, hydraulic parts, automotive parts, industrial fittings, and mechanical components.
Longer Machining Range for Medium-Length Parts
The 560 mm maximum turning length and 580 mm Z-axis travel help manufacturers process longer parts with better flexibility. This is useful for shaft components, tube-type parts, mechanical connectors, and custom industrial parts.
Stable Machining for Difficult Materials
The machine is suitable for rough and finish machining of stainless steel, titanium alloy, carbon steel, mold steel, and other materials. Its rigid casting structure, stable spindle system, and slant bed design help support consistent machining 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.
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 turret configurations.
This makes the J76-600LU 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 for Model 76, 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.
