Our advantage:Thread Rolling Machine for Roller Screw Actuators

The cold-rolled screw rolling machine is a key for manufacturing Ball Screws and Planetary Roller Screw.Most manufacturers use "dovetail rail" structure thread rolling machine. The "dovetail rail" needs to be added with "shims" to adjust the matching clearance. The defect is it cannot be pushed axially if it is locked, and there will be radial deflection if the lock is loose, the Ball Screws Assemblies will have "black and white circles", the Ball Screws will have inconsistent contours and roundness, and the assembly nut will have "one circle is tight and one circle is loose".

The radial drive of the thread rolling machine generally adopts hydraulic drive, and the floating nature of the holding pressure determines the consistency of the screw pitch diameter.

We launch two structures: Rexroth hydraulic system and servo drive according to different screw requirements; The transmission mechanism adopts ground trapezoidal screw and ground Ball Screws are respectively configured in hydraulic thread rolling machines and servo thread rolling machines. The above measures can reduce the impact of unstable driving on the precision of the cold-rolled screw.
