RSVP tangential side rolling attachments were originally developed to roll threads behind a shoulder. The process requires the rolls to be plunged, at a controlled rate, into the rotating component. Tangential side rolling attachments may be mounted in any machine tool having a cross slide or turret with a controlled feed stroke. The attachment is mounted in a holder that has been designed for a specific machine tool. There must be clearance between the attachment and machine tool, as well as between the arms of the attachment and any shoulder on the component.
For left-hand threads, the same attachment can be used as for right-hand threads. Left-hand threads require left-hand rolls.
RSVP - Tangential side rolling attachments, Type RT, have a capacity range to 64 mm/2.52".
Capacity ranges are shown in the adjoining table.
The thread length including thread runout can not exceed the width of the roll. For shorter threads, rolls can be supplied with a recess for additional clearance. Roll width must be specified.
Also attachments with smaller construction numbers are suitable in the same work range, there are exceptions.
