Precision, Versatility, and Efficiency: The Heavy Duty Series

Versatile Performance:  
✓ Provide versatility with one moveable and one fixed head, making them suitable for heavy-duty threading and cold forming on cylindrical components. 
✓ Comply with various standards (ISO, ACME, TPN, WORM SCREWS, etc.) and deliver rapid and precise plunge and thru-feed thread rolling operations.  
✓ Equipped with PLC or CNC control units. 
✓ All enhanced with advanced Movable Front Spindle Support Housing.

Built to Last: 
Robust slideways and spindle support housings ensure exceptional strength and rigidity, minimizing the risk of deflection and guaranteeing a long and productive machine life. Operators can conveniently access all controls and adjustments from the front position.

Advanced Features: 
The Heavy Duty series offer advanced capabilities -  Preselector time control for automated cycling, Roll slide positive stop, and Automatic lubrication.

High-Speed Productivity: 
The PM-120VS-HS model boasts a High-Speed Gear Box with double spindle speeds, perfect for mass-producing All-Threaded-Bar and doubling productivity.

Double the Efficiency: 
The PM-120VS-TWIN introduces an innovative mechanism with 2 pairs of thread rolling dies, enabling synchronous plunge-feed thread rolling on both ends of the component, accommodating lengths of up to 300 mm, and doubling productivity.

Specialized Threads:
The Heavy Duty Series is your go-to for specialized threads such as Trapezoid (TR), DIN 405 Knuckle Thread, Spline Rolling, Ball Screw, Heavy Duty Tie Rod, Diamond Knurling, and Straight Knurling.
