Ball Screw Whirling Machine
Designed for high-efficiency thread machining of long-shaft components such as ball screws and worm shafts, the high-precision CNC ball screw whirling machine is a dedicated solution for precision transmission manufacturing. Using high-speed whirling cutter head enveloping milling, threads are formed in a single pass, achieving high productivity with minimal grinding allowance and making the system well suited for batch production environments.
Widely adopted in the precision machining of ball screws, planetary roller screws, and large-lead transmission screws, this whirling system serves as a core piece of equipment for the mass production of precision transmission components.

Key Advantages
- Easy Operation: The control system is equipped with SIEMENS 828D/840D CNC platforms, combined with HEIDENHAIN/FAGOR precision linear scales and Renishaw encoders, enabling full closed-loop control.
- Intelligent Compensation: Features single-pass cyclic milling with automated capabilities for continuous machining, multi-start thread milling, dynamic tool setting, and precise lead/pitch diameter taper compensation.
- Stable Precision: Synchronous CNC control guarantees superior lead accuracy and profile consistency. Precisely controlled grinding allowances fully support C3/C5 grade ball screw process chains.
- High Flexibility: By changing the cutter head and adjusting the A-axis, complex thread forms such as multi-start threads, variable-lead threads, and planetary roller screws can be processed with ease.
- Green Machining: Supports dry cutting and minimum quantity lubrication (MQL), significantly reducing coolant consumption and environmental disposal costs.
- High Efficiency: Roughing and semi-finishing operations are completed in a single setup, delivering productivity levels 5-20 times higher than traditional turning methods and making the solution ideal for large-scale production.
