THREAD ROLLING ATTACHMENTS FOR LATHES AND AUTOMATIC SCREW MACHINES

What It’s All About…

Thread rolling is an economical method of producing smooth precision threads at high production rates. Close tolerances are easier to maintain, threads are stronger, downtime for replacing tooling is minimized and the original accuracy of the setup is maintained on long runs.

 

The uniformity of rolled threads reduces inspection time to a minimum, resulting in considerable savings in those costs. Threads can be rolled close to the front and rear of shoulders, which many times will eliminate a secondary threading operation.

 

Reed-Rico Thread Rolling Attachments are designed to operate from the cross slides of automatic screw machines and lathes and consist of two units…a head and an adapter.

 

Six standard heads make possible the selection of an attachment that will provide the maximum thread rolling capacity within the tooling sectors of more than 100 sizes of single and multiple spindle screw machines.

 

Adapters are of solid or adjustable type and are designed for selected cross slide positions on the automatics. A large assortment of adapters is available for more than 500 applications.

 

The Senes B Attachment is a precision tool. It is rugged in construction, easy to adjust and set up. and is capable of rolling class 2A or 3A threads.

 

The following features, exclusive with Reed-Rico, account for superior roll performance, longer roll life, less machine downtime and better quality threads.

   
  • Advance and Alignment Compensators
  • Anti-Friction Bearings
  •  
  • Simple Precise Roll Matching
  • Dovetail Clamping Arrangement

Design Features

Advance Compensator

Roll “wind-up” caused by one roll rotating counter to the direction of attachment advance as the rolls move into the work, is automatically compensated for, by an advance compensating device within the head without placing any undue strain on the gear train. The Advance Compensator insures perfect synchronization of the thread rolls during rolling operation.

Alignment Compesator

Accurate positioning of the rolls in the head, accomplished by four independently adjustable arms, and a vertical floating arrangement in the adapter, provides automatic parallel alignment of the rolls with the center line of the work throughout the rolling cycle. The Alignment Compensator also assures smooth contacting and withdrawal of the rolls to and from the work.

Anti-friction Bearings

Anti-friction thrust bearings on both sides of the thread rolls minimizes unnecessary wear on the rolls from any side movement. Not only is this important when rolling straight threads, but it also accounts for exceptional performance when taper Pipe threading.

Simple Precision Matching

Precise matching of the rolls is important in the operation of a two-roll geared type thread rolling attachment. To obtain accurate threads, it is necessary that the rolls track property on the work blank. The simple micrometer adjusting device provides a positive means of positioning both rolls for proper tracking.

Dovetail Clamping Arrangement

The dovetail design of the connection between the head and the adapter makes it possible to easily remove the head from the machine for changing or adjusting rolls, or for convenience in making adjustments, without removing the adapter from the cross slide. This feature combined with an adjustable and positive locating stop, assures that the head will always be reassembled in the adapter in the same relative position to the work.
