L400-PW
ZRD
ZRD-L400-PW is a precision worm CNC whirling machine designed for worm shaft machining, miniature worm shafts, screw shafts, and high-accuracy thread production. Powered by advanced whirling technology, it replaces traditional grinding and multi-step milling with one-pass forming, delivering superior efficiency and accuracy.
Integrated worm thread whirling ensures stable, uniform forming and reduces vibration during high-speed machining.
The high-rigidity structure guarantees consistent precision for long-term, continuous production.

A Precision Worm CNC Whirling Machine is a specialized CNC tool designed to produce high-accuracy worm shafts and threads. It uses the whirling process to achieve superior surface finish, consistent pitch, and excellent dimensional accuracy, making it ideal for gear manufacturing, automotive parts, and precision machinery industries.
This machine can process a wide range of materials, including alloy steel, stainless steel, carbon steel, brass, and aluminum alloys. The high-speed whirling process ensures stable cutting even with hard-to-machine materials.
Unlike traditional single-point cutting, CNC whirling uses multiple cutting edges rotating around the workpiece at high speed. This reduces machining time, improves thread precision, and extends tool life. It is especially suitable for deep threads and long worm shafts.
High accuracy for complex worm and screw profiles
Faster production speed compared to conventional turning
Excellent surface finish without secondary grinding
Longer tool life thanks to reduced cutting pressure
Lower noise and vibration during machining
Common industries include:
Gear manufacturing
Automotive components
Aerospace parts
Robotics and automation equipment
Medical device manufacturing
Depending on the model, a Precision Worm CNC Whirling Machine can process worm shafts up to 400mm or longer. Custom configurations are available for extended lengths.
Yes. With advanced CNC control and programmable settings, the whirling machine can produce custom pitch, lead angle, and tooth profiles according to customer drawings or CAD models.
Regularly clean chips and debris from the cutting area
Monitor cutting tool wear and replace inserts promptly
Check spindle alignment and lubrication systems
Update CNC software and parameters for optimal accuracy
