VABS screw rolling head
Large diameter screw rolling, dedicated machine rolling attachment
This is a brand suitable for screw machining larger than ARC size and for rolling heads mounted as dedicated machine attachments. ■ Features of VABS (Vabs) Screw Rolling Heads - Can be mounted on CNC lathes, allowing the integration of cutting and rolling processes into a single CNC lathe. - Has a wealth of experience in processing large screws ranging from a minimum of M2.6 to a maximum of M138. - Has a proven track record in the production of trapezoidal screws and screws with special shapes. - Can also provide closing devices. ■ 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 has a glossy finish. 3. Reduced processing time High-speed pitch feeding allows for relatively short processing times for finishing in one go. 4. Reduced setup time The lifespan of rolls is generally longer compared to cutting, which reduces 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.
