When it comes to close-tolerance manufacturing of complex shapes from leaded alloy steel, Rathbone Precision Metals, Inc.’s cold drawn expertise enables us to produce profiles that are superior in quality and less costly than their machined counterparts. Using 86L20 Steel, we use a cold draw process to form the unique tooth configuration per customer specifications, which eliminates the need for broaching. In addition, we control the corners, and fillet radii to ±.005″ tolerance, that would be difficult to cost effectively achieve by broaching. With a major diameter of 1.219″, minor diameter of .906″, and 125 Ra max finish, the profile is delivered to the customer in average 14′ random mill bar lengths. This complex shape is cold drawn with much less waste and with greater precision than the machined alternative offered, saving the customer time and money. To learn more about this profile as well as others, or how cold drawn and cold rolled profiles could benefit your application, please contact Rathbone today.
