YJ-CK300ST Single-Spindle Double Turret Lathe
Center-Drive Single Spindle Double Turret CNC Lathe Series

YJ-CK300ST Single-Spindle Double Turret Lathe

Feed System
The machine feed motions are controlled by a FANUC dual-channel CNC system, independently controlling two sets of cross slide units. Servo motors drive the ball screws to realize bidirectional feed of both the saddle and slides. Both the saddle and slides are equipped with high-precision linear rolling guideways.

Spindle System
The precision collet-type bidirectional spindle is driven by a dedicated servo spindle motor. The spindle speed can be freely adjusted within the speed range through CNC programming control.

Spindle and Spindle Drive
The machine spindle is a specially designed double-ended collet turning spindle. The designed spindle speed is 400 r/min. The spindle is driven by a 22 kW dedicated servo spindle motor. Power is transmitted via belt drive, and different spindle speeds can be set through CNC control.

Feed Drive System
The feed system converts the rotary motion of servo motors into linear motion through ball screws, driving the precision slides to achieve linear feed during machining. The servo motors are manufactured by SYNTEC and provide bidirectional feed control. Ball screws and guideways are sourced from Taiwan.
The slide body is made of HT300 cast iron and undergoes annealing and harmonic vibration aging treatment to ensure structural stability.
Rapid traverse speed: 22 m/min
Minimum feed increment: 0.001 mm

Workpiece Clamping
Workpieces are clamped using elastic collets. The collet is integrated with the spindle. Different elastic collets are required for different workpiece sizes.
Required working pressure: <1.5 MPa
The hydraulic station is equipped with an oil cooler to ensure the temperature rise of the oil tank and spindle clamping unit remains below 45°C.

Supporting Multi-Operation Turning: The Role of Dual-Turret CNC Lathes in Component Machining

What Is a Single-Spindle Double-Turret CNC Lathe?

A Single-Spindle Double-Turret CNC Lathe is a computer-controlled turning machine with one main spindle and two tool turrets. In simple terms, the spindle rotates the workpiece, while the two turrets hold different cutting tools for machining.

The two-turret design provides more tooling options and allows machining operations to be divided between two tool groups. Depending on the machine configuration and workpiece, the turrets can perform separate or coordinated operations.

Specific Applications

This CNC Turning Machine is suitable for repeated production of metal components used in automotive, hydraulic, pneumatic, machinery, agricultural equipment, and industrial applications.

Typical applications include:

  • Automotive parts: shafts, hubs, pins, sleeves, bushings, and transmission components
  • Hydraulic parts: pistons, valve components, fittings, connectors, sleeves, and cylindrical housings
  • Pneumatic components: adapters, joints, fittings, and precision cylindrical parts
  • Machinery components: rollers, flanges, bearing seats, couplings, shafts, and threaded parts
  • Agricultural machinery: drive shafts, pins, hubs, bushings, and connecting components
  • Industrial parts: rings, adapters, housings, pins, and other turned components
  • Multi-operation components: parts requiring turning, facing, boring, grooving, drilling, chamfering, and threading

For example, a hydraulic component may require external diameter turning, facing, grooving, and threading. Two turrets can provide separate tool groups for these operations, depending on the machining process.

Core Functions

Depending on the configuration, the machine can perform external and internal turning, facing, boring, drilling, grooving, chamfering, and threading.

When evaluating the machine, customers should check spindle power and speed, maximum turning diameter, workpiece length, turret type, tool capacity, CNC control system, chuck configuration, positioning accuracy, repeatability, and automation compatibility.

For precision turning applications, workholding stability, tool positioning, coolant delivery, chip removal, and thermal control are also important factors.

Why Is It Purchased?

Private Brand: Machinery distributors can introduce this CNC Turning Machine under their own brand through OEM/ODM cooperation. Custom options may include machine appearance, nameplates, labels, manuals, packaging, and selected technical configurations.

Bulk Supply: Equipment distributors can supply the machine to factories producing shafts, fittings, hydraulic parts, automotive components, and other turned products with recurring production needs.

Cost Optimization: Manufacturers may consider a double-turret configuration when frequent tool changes, repeated setups, or separate machining stages increase production time. A suitable arrangement can help organize several operations within one CNC turning process.

What Customer Problems Can It Solve?

Does the target market require several cutting tools for one component? Are repeated tool changes affecting production schedules? Do operators spend time setting up separate machining stages? Are manufacturers looking for greater tooling flexibility without adding another spindle?

A suitable Single-Spindle Double-Turret CNC Lathe can provide two tool groups around one main spindle, helping organize multi-operation turning and reduce unnecessary workpiece handling.

OEM/ODM Support

OEM/ODM cooperation may include turret configuration, spindle specifications, CNC system selection, chuck and tooling systems, automation interfaces, machine appearance, branding, packaging, technical documentation, and application-specific modifications.

When evaluating a manufacturer, customers should examine engineering capability, turret and spindle design, production capacity, machine testing, dimensional inspection, spare-parts availability, installation support, and after-sales service.

The machine should be configured according to actual workpiece drawings, material, dimensions, machining sequence, tolerance, production volume, and automation requirements. This helps customers determine whether the CNC Turning Machine matches their target applications and whether the manufacturer can support long-term private-label, distribution, and OEM/ODM cooperation.
