Double Tandem Scarfing Units

The Addison Machine Double-Tandem Scarfing Unit is fabricated using a heavy steel weldment frame that is precision machined to accommodate a lower and upper unit.

Function

The Double Tandem Scarfing Unit removes excess material from weld seam on outside of tube.

Features

• The lower unit utilizes hardened "Vee" rollers to support the tube during the scarfing operation.
• The Pass-line adjustment is maintained by adjusting the roll housings via individual gear assemblies with the adjusters conveniently located on the front of the unit.
• The upper unit contains the O.D. scarfing cutting tools which are located in toolholders that are adjustable simultaneously and/or individually (the latter is primarily used for depth of cut adjustments).
• The toolholders are mounted onto two-way hardened dovetail slides, these slides allow for both vertical and lateral adjustment. This dovetail design limits the chances of tool "harmonics" and allows for periodic adjustments due to normal slide wear. The toolholders accept square shank type cutting tool holders (specify either 5/8" square or 3/4" square). The toolholder has a positive locator "Lip" to lock the square shank into position.
• Each toolholder assembly has a spring-loaded cam quick release/engage to quickly raise and lower the O.D. scarfing cutting tools off/on of the tube. This quick release is activated by a manual "stick" lever by the operator.
