ARC screw rolling head
Consolidation of thread rolling processing.
The screw rolling head typically involves three rolls and enters the material from the end face in the axial direction to roll the screw. It uses a step rolling method that rolls one thread at a time from the tip, resulting in less load on the machine and the workpiece. Regardless of the rotation speed, it advances by the pitch per rotation. The rolls can advance in the axial direction regardless of their length, allowing for flexible setting of screw length. There are F-type heads used for rotating workpieces (such as lathes) and G-type heads that can rotate the head (used for machining centers, etc.). ■ Features of the ARC screw rolling head - It can be mounted on CNC lathes, allowing the cutting process and rolling process to be consolidated into a single CNC lathe. ■ Advantages of rolled screws 1. Improved screw strength Strength is enhanced due to work hardening from plastic deformation and densification of the structure. 2. Improved surface roughness The surface is varnished and finished with a glossy appearance. 3. Reduced processing time With high peripheral speeds and pitch feeding, the processing time is relatively short for finishing. 4. Reduced setup time The lifespan of the rolls is generally longer compared to cutting tools, reducing the frequency of tool changes. 5. Prevention of burrs, cracks, and rust The structure becomes stronger due to plastic deformation, significantly reducing the defect rate.
