For producing long threads, or threads without run-out restriction, RSVP axial rolling heads are a good selection, according to the company. Axial heads feed on from the end of the part and require one revolution of the spindle for each pitch of thread to be produced. Controlled forward axial motion, either by cam or CNC feed, are recommended, although manually operated lathes can also give excellent results. RSVP axial heads are self opening and require an external closing action to reset them. Right-hand rolling heads are required for rolling right-hand threads, and the spindle direction must also be right hand. Left-hand threads require corresponding heads and spindle rotation. RSVP thread rolling heads and replacement thread rolls exceed the industry standard for durability and performance. Our on-site technical staff can provide superior advice regarding your application from installation, material selection and performance.
